Occupational safety and health

This painting depicts a woman examining her work on a lathe at a factory in Britain during World War II. Her eyes are not protected. Today, such practice would not be permitted in most industrialized countries that adhere to occupational health and safety standards for workers. In many countries however, such standards are still either weak or nonexistent.

Occupational safety and health (OSH), also commonly referred to as occupational health and safety (OHS), occupational health,^[1] or workplace health and safety (WHS), is a multidisciplinary field concerned with the safety, health, and welfare of people at work. These terms of course also refer to the goals of this field,^[2] so their use in the sense of this article was originally an abbreviation of occupational safety and health program/department etc.

The goals of occupational safety and health programs include to foster a safe and healthy work environment.^[3] OSH may also protect co-workers, family members, employers, customers, and many others who might be affected by the workplace environment. In the United States, the term occupational health and safety is referred to as occupational health and occupational and non-occupational safety and includes safety for activities outside of work.^[4]

In common-law jurisdictions, employers have a common law duty to take reasonable care of the safety of their employees.^[5] Statute law may in addition impose other general duties, introduce specific duties, and create government bodies with powers to regulate workplace safety issues: details of this vary from jurisdiction to jurisdiction.

All organizations have the duty to ensure that employees and any other person who may be affected by the organization's activities remain safe at all times.

As defined by the World Health Organization (WHO) "occupational health deals with all aspects of health and safety in the workplace and has a strong focus on primary prevention of hazards."^[6] Health has been defined as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity."^[7] Occupational health is a multidisciplinary field of healthcare concerned with enabling an individual to undertake their occupation, in the way that causes least harm to their health. Health has been defined as It contrasts, for example, with the promotion of health and safety at work, which is concerned with preventing harm from any incidental hazards, arising in the workplace.

Since 1950, the International Labour Organization (ILO) and the World Health Organization (WHO) have shared a common definition of occupational health. It was adopted by the Joint ILO/WHO Committee on Occupational Health at its first session in 1950 and revised at its twelfth session in 1995. The definition reads:

"The main focus in occupational health is on three different objectives: (i) the maintenance and promotion of workers’ health and working capacity; (ii) the improvement of working environment and work to become conducive to safety and health and (iii) development of work organizations and working cultures in a direction which supports health and safety at work and in doing so also promotes a positive social climate and smooth operation and may enhance productivity of the undertakings. The concept of working culture is intended in this context to mean a reflection of the essential value systems adopted by the undertaking concerned. Such a culture is reflected in practice in the managerial systems, personnel policy, principles for participation, training policies and quality management of the undertaking."

— Joint ILO/WHO Committee on Occupational Health^[8]

Those in the field of occupational health come from a wide range of disciplines and professions including medicine, psychology, epidemiology, physiotherapy and rehabilitation, occupational therapy, occupational medicine, human factors and ergonomics, and many others. Professionals advise on a broad range of occupational health matters. These include how to avoid particular pre-existing conditions causing a problem in the occupation, correct posture for the work, frequency of rest breaks, preventative action that can be undertaken, and so forth.

"Occupational health should aim at: the promotion and maintenance of the highest degree of physical, mental and social well-being of workers in all occupations; the prevention amongst workers of departures from health caused by their working conditions; the protection of workers in their employment from risks resulting from factors adverse to health; the placing and maintenance of the worker in an occupational environment adapted to his physiological and psychological capabilities; and, to summarize, the adaptation of work to man and of each man to his job.

History

Harry McShane, age 16, 1908. Pulled into machinery in a factory in Cincinnati and had his arm ripped off at the shoulder and his leg broken without any compensation.

The research and regulation of occupational safety and health are a relatively recent phenomenon. As labor movements arose in response to worker concerns in the wake of the industrial revolution, worker's health entered consideration as a labor-related issue.

In the United Kingdom, the Factory Acts of the early nineteenth century (from 1802 onwards) arose out of concerns about the poor health of children working in cotton mills: the Act of 1833 created a dedicated professional Factory Inspectorate.^{[9] :41} The initial remit of the Inspectorate was to police restrictions on the working hours in the textile industry of children and young persons (introduced to prevent chronic overwork, identified as leading directly to ill-health and deformation, and indirectly to a high accident rate). However, on the urging of the Factory Inspectorate, a further Act in 1844 giving similar restrictions on working hours for women in the textile industry introduced a requirement for machinery guarding (but only in the textile industry, and only in areas that might be accessed by women or children).^{[9] :85}

In 1840 a Royal Commission published its findings on the state of conditions for the workers of the mining industry that documented the appallingly dangerous environment that they had to work in and the high frequency of accidents. The commission sparked public outrage which resulted in the Mines Act of 1842. The act set up an inspectorate for mines and collieries which resulted in many prosecutions and safety improvements, and by 1850, inspectors were able to enter and inspect premises at their discretion.^[10]

Otto von Bismarck inaugurated the first social insurance legislation in 1883 and the first worker's compensation law in 1884 – the first of their kind in the Western world. Similar acts followed in other countries, partly in response to labor unrest.^[11]

Workplace hazards

Although work provides many economic and other benefits, a wide array of workplace hazards also present risks to the health and safety of people at work. These include but are not limited to, "chemicals, biological agents, physical factors, adverse ergonomic conditions, allergens, a complex network of safety risks," and a broad range of psychosocial risk factors.^[12] Personal protective equipment can help protect against many of these hazards.

Physical hazards affect many people in the workplace. Occupational hearing loss is the most common work-related injury in the United States, with 22 million workers exposed to hazardous noise levels at work and an estimated $242 million spent annually on worker's compensation for hearing loss disability.^[13] Falls are also a common cause of occupational injuries and fatalities, especially in construction, extraction, transportation, healthcare, and building cleaning and maintenance.^[14] Machines have moving parts, sharp edges, hot surfaces and other hazards with the potential to crush, burn, cut, shear, stab or otherwise strike or wound workers if used unsafely.^[15]

Biological hazards (biohazards) include infectious microorganisms such as viruses and toxins produced by those organisms such as anthrax. Biohazards affect workers in many industries; influenza, for example, affects a broad population of workers.^[16] Outdoor workers, including farmers, landscapers, and construction workers, risk exposure to numerous biohazards, including animal bites and stings,^[17][18][19] urushiol from poisonous plants,^[20] and diseases transmitted through animals such as the West Nile virus and Lyme disease.^[21][22] Health care workers, including veterinary health workers, risk exposure to blood-borne pathogens and various infectious diseases,^[23][24] especially those that are emerging.^[25]

Dangerous chemicals can pose a chemical hazard in the workplace. There are many classifications of hazardous chemicals, including neurotoxins, immune agents, dermatologic agents, carcinogens, reproductive toxins, systemic toxins, asthmagens, pneumoconiotic agents, and sensitizers.^[26] Authorities such as regulatory agencies set occupational exposure limits to mitigate the risk of chemical hazards.^[27] An international effort is investigating the health effects of mixtures of chemicals. There is some evidence that certain chemicals are harmful at lower levels when mixed with one or more other chemicals. This may be particularly important in causing cancer.^[28]

Psychosocial hazards include risks to the mental and emotional well-being of workers, such as feelings of job insecurity, long work hours, and poor work-life balance.^[29] A recent Cochrane review - using moderate quality evidence - related that the addition of work-directed interventions for depressed workers receiving clinical interventions reduces the number of lost work days as compared to clinical interventions alone.^[30] This review also demonstrated that the addition of cognitive behavioral therapy to primary or occupational care and the addition of a "structured telephone outreach and care management program" to usual care are both effective at reducing sick leave days.^[30]

By industry

Specific occupational safety and health risk factors vary depending on the specific sector and industry. Construction workers might be particularly at risk of falls, for instance, whereas fishermen might be particularly at risk of drowning. The United States Bureau of Labor Statistics identifies the fishing, aviation, lumber, metalworking, agriculture, mining and transportation industries as among some of the more dangerous for workers.^[31] Similarly psychosocial risks such as workplace violence are more pronounced for certain occupational groups such as health care employees, police, correctional officers and teachers.^[32]

Construction

Construction is one of the most dangerous occupations in the world, incurring more occupational fatalities than any other sector in both the United States and in the European Union.^[33][34] In 2009, the fatal occupational injury rate among construction workers in the United States was nearly three times that for all workers.^[33] Falls are one of the most common causes of fatal and non-fatal injuries among construction workers.^[33] Proper safety equipment such as harnesses and guardrails and procedures such as securing ladders and inspecting scaffolding can curtail the risk of occupational injuries in the construction industry.^[35] Due to the fact that accidents may have disastrous consequences for employees as well as organizations, it is of utmost importance to ensure health and safety of workers and compliance with HSE construction requirements. Health and safety legislation in the construction industry involves many rules and regulations. For example, the role of the Construction Design Management (CDM) Coordinator as a requirement has been aimed at improving health and safety on-site.^[36]

The 2010 National Health Interview Survey Occupational Health Supplement (NHIS-OHS) identified work organization factors and occupational psychosocial and chemical/physical exposures which may increase some health risks. Among all U.S. workers in the construction sector, 44% had non-standard work arrangements (were not regular permanent employees) compared to 19% of all U.S. workers, 15% had temporary employment compared to 7% of all U.S. workers, and 55% experienced job insecurity compared to 32% of all U.S. workers. Prevalence rates for exposure to physical/chemical hazards were especially high for the construction sector. Among nonsmoking workers, 24% of construction workers were exposed to secondhand smoke while only 10% of all U.S. workers were exposed. Other physical/chemical hazards with high prevalence rates in the construction industry were frequently working outdoors (73%) and frequent exposure to vapors, gas, dust, or fumes (51%).^[37]

Agriculture

Agriculture workers are often at risk of work-related injuries, lung disease, noise-induced hearing loss, skin disease, as well as certain cancers related to chemical use or prolonged sun exposure. On industrialized farms, injuries frequently involve the use of agricultural machinery. The most common cause of fatal agricultural injuries in the United States is tractor rollovers, which can be prevented by the use of roll over protection structures which limit the risk of injury in case a tractor rolls over.^[38] Pesticides and other chemicals used in farming can also be hazardous to worker health, and workers exposed to pesticides may experience illnesses or birth defects.^[39] As an industry in which families, including children, commonly work alongside their families, agriculture is a common source of occupational injuries and illnesses among younger workers.^[40] Common causes of fatal injuries among young farm worker include drowning, machinery and motor vehicle-related accidents.^[41]

The 2010 NHIS-OHS found elevated prevalence rates of several occupational exposures in the agriculture, forestry, and fishing sector which may negatively impact health. These workers often worked long hours. The prevalence rate of working more than 48 hours a week among workers employed in these industries was 37%, and 24% worked more than 60 hours a week. Of all workers in these industries, 85% frequently worked outdoors compared to 25% of all U.S. workers. Additionally, 53% were frequently exposed to vapors, gas, dust, or fumes, compared to 25% of all U.S. workers.^[42]

Service sector

As the number of service sector jobs has risen in developed countries, more and more jobs have become sedentary, presenting a different array of health problems than those associated with manufacturing and the primary sector. Contemporary problems such as the growing rate of obesity and issues relating to occupational stress, workplace bullying, and overwork in many countries have further complicated the interaction between work and health.

According to data from the 2010 NHIS-OHS, hazardous physical/chemical exposures in the service sector were lower than national averages. On the other hand, potentially harmful work organization characteristics and psychosocial workplace exposures were relatively common in this sector. Among all workers in the service industry, 30% experienced job insecurity in 2010, 27% worked non-standard shifts (not a regular day shift), 21% had non-standard work arrangements (were not regular permanent employees).^[43]

Mining and oil & gas extraction

According to data from the 2010 NHIS-OHS, workers employed in mining and oil & gas extraction industries had high prevalence rates of exposure to potentially harmful work organization characteristics and hazardous chemicals. Many of these workers worked long hours: 50% worked more than 48 hours a week and 25% worked more than 60 hours a week in 2010. Additionally, 42% worked non-standard shifts (not a regular day shift). These workers also had high prevalence of exposure to physical/chemical hazards. In 2010, 39% had frequent skin contact with chemicals. Among nonsmoking workers, 28% of those in mining and oil and gas extraction industries had frequent exposure to secondhand smoke at work. About two-thirds were frequently exposed to vapors, gas, dust, or fumes at work.^[44]

Healthcare and social assistance

Healthcare workers are exposed to many hazards that can adversely affect their health and well-being. Long hours, changing shifts, physically demanding tasks, violence, and exposures to infectious diseases and harmful chemicals are examples of hazards that put these workers at risk for illness and injury.

According to the Bureau of Labor statistics, U.S. hospitals recorded 253,700 work-related injuries and illnesses in 2011, which is 6.8 work-related injuries and illnesses for every 100 full-time employees.^[45] The injury and illness rate in hospitals is higher than the rates in construction and manufacturing – two industries that are traditionally thought to be relatively hazardous.

The Occupational Health Safety Network (OHSN)^[46] is a secure electronic surveillance system developed by the National Institute for Occupational Safety and Health (NIOSH) to address health and safety risks among health care personnel. OHSN uses existing data to characterize risk of injury and illness among health care workers. Hospitals and other healthcare facilities can upload the occupational injury data they already collect to the secure database for analysis and benchmarking with other de-identified facilities. NIOSH works with OHSN participants in identifying and implementing timely and targeted interventions. OHSN modules currently focus on three high risk and preventable events that can lead to injuries or musculoskeletal disorders among healthcare personnel: musculoskeletal injuries from patient handling activities;^[47] slips, trips, and falls; and workplace violence. OHSN enrollment is open to all healthcare facilities.

Workplace fatality and injury statistics

United States

The Bureau of Labor Statistics of the United States Department of Labor compiles information about workplace fatalities and non-fatal injuries in the United States. In 1970, an estimated 14,000 workers were killed on the job – by 2010, the workforce had doubled, but workplace deaths were down to about 4,500.^[48]
Between 1913 and 2013, workplace fatalities dropped by approximately 80%.^[49]

Number of occupational fatal work injuries in the U.S. from 1992 until 2014. Note, 2001 statistics do not include death related to the September 11 terrorist attacks.

The Bureau also compiles information about the most dangerous jobs. According to the census of occupational injuries 4,679 people died on the job in 2014.^[50]

Musculoskeletal injuries accounted for 32% of all employer-reported injuries and illnesses in 2014.^[53]

European Union

In most countries males comprise the vast majority of workplace fatalities. In the EU as a whole, 94% of death were of males.^[54] In the UK the disparity was even greater with males comprising 97.4% of workplace deaths. In the UK there were 171 fatal injuries at work in financial year 2011-2, compared with 651 in calendar year 1974; the fatal injury rate declined over that period from 2.9 fatalities per 100,000 workers to 0.6 per 100,000 workers^[55]

Management systems

International

In 2001, the International Labor Organization (ILO) published ILO-OSH 2001, also titled "Guidelines a on occupational safety and health management systems" to assist organizations with introducing OSH management systems.^[56] These guidelines encourage continual improvement in employee health and safety, achieved via a constant process of policy, organization, planning & implementation, evaluation, and action for improvement, all supported by constant auditing to determine the success of OSH actions.^[56]

The ILO management system was created to assist employers to keep pace with rapidly shifting and competitive industrial environments. The ILO recognizes that national legislation is essential, but sometimes insufficient on its own to address the challenges faced by industry, and therefore elected to ensure free and open distribution of administrative tools in the form of occupational health and safety management system guidance for everyone. This open access forum is intended to provide the tools for industry to create safe and healthy working environments and foster positive safety cultures within the organizations.

OHSAS 18000 is an international occupational health and safety management system specification developed by the London-based BSI Group, a multinational business chiefly concerned with the production and distribution of standards related services. OHSAS 18000 comprises two parts, OHSAS 18001 and 18002 and embraces a number of other publications. OHSAS 18000 is the internationally recognized assessment specification for occupational health and safety management systems. It was developed by a selection of leading trade bodies, international standards and certification bodies to address a gap where no third-party certifiable international standard exists. This internationally recognized specification for occupational health and safety management system operates on the basis of policy, planning, implementation and operation, checking and corrective action, management review, and continual improvement.

The British Standards – Occupational Health and Safety management Systems Requirements Standard BS OHSAS 18001 was developed within the framework of the ISO standards series. Allowing it to integrate better into the larger system of ISO certifications. ISO 9001 Quality Management Systems and ISO 14001 Environmental Management System can work in tandem with BS OHSAS 18001/18002 to complement each other and form a better overall system. Each component of the system is specific, auditable, and accreditable by a third party after review.^[57]

Also Standards Australia and the Association Française de Normalisation (AFNOR) in France have developed occupational safety and health management standards.^[58]

United Kingdom

Guidance note HSG65: Successful Health and Safety Management, published by the British non-departmental public body Health and Safety Executive, was substantially re-written 2013. It now promotes the Plan Do Check Act approach to health and safety management, sharing similarities with BS OHSAS 18001. This achieved a balance between the original systems-based approach, and the more modern behavioural approach to safety management.^[59]

National legislation and public organizations

Occupational safety and health practice vary among nations with different approaches to legislation, regulation, enforcement, and incentives for compliance. In the EU, for example, some member states promote OSH by providing public monies as subsidies, grants or financing, while others have created tax system incentives for OSH investments. A third group of EU member states has experimented with using workplace accident insurance premium discounts for companies or organisations with strong OSH records.^[60]

Australia

In Australia, the Commonwealth, four of the six states and both territories have enacted and administer harmonised Work Health and Safety Legislation in accordance with the Intergovernmental Agreement for Regulatory and Operational Reform in Occupational Health and Safety.^[61] Each of these jurisdictions has enacted Work Health & Safety legislation and regulations based on the Commonwealth Work Health and Safety Act 2011 and common Codes of Practice developed by Safe Work Australia.^[62] Some jurisdictions have also included mine safety under the model approach, however, most have retained separate legislation for the time being. Western Australia intends to adopt a moderated version of the model approach and Victoria has retained its own regime, although the Model WHS laws themselves drew heavily on the Victoria approach.

Canada

In Canada, workers are covered by provincial or federal labour codes depending on the sector in which they work. Workers covered by federal legislation (including those in mining, transportation, and federal employment) are covered by the Canada Labour Code; all other workers are covered by the health and safety legislation of the province in which they work. The Canadian Centre for Occupational Health and Safety (CCOHS), an agency of the Government of Canada, was created in 1966 by an Act of Parliament. The act was based on the belief that all Canadians had "...a fundamental right to a healthy and safe working environment." CCOHS is mandated to promote safe and healthy workplaces to help prevent work-related injuries and illnesses. The CCOHS maintains a useful (partial) list of OSH regulations for Canada and its provinces.^[63]

European Union

In the European Union, member states have enforcing authorities to ensure that the basic legal requirements relating to occupational health and safety are met. In many EU countries, there is strong cooperation between employer and worker organisations (e.g. unions) to ensure good OSH performance as it is recognized this has benefits for both the worker (through maintenance of health) and the enterprise (through improved productivity and quality). In 1996, the European Agency for Safety and Health at Work was founded.

Member states of the European Union have all transposed into their national legislation a series of directives that establish minimum standards on occupational health and safety. These directives (of which there are about 20 on a variety of topics) follow a similar structure requiring the employer to assess the workplace risks and put in place preventive measures based on a hierarchy of control. This hierarchy starts with elimination of the hazard and ends with personal protective equipment.

However, certain EU member states admit to having lacking quality control in occupational safety services, to situations in which risk analysis takes place without any on-site workplace visits and to insufficient implementation of certain EU OSH directives. Based on this, it is hardly surprising that the total societal costs of work-related health problems and accidents vary from 2.6% to 3.8% of GNP between the EU member states.^[65]

Denmark

In Denmark, occupational safety and health is regulated by the Danish Act on Working Environment and cooperation at the workplace.^[66] The Danish Working Environment Authority carries out inspections of companies, draws up more detailed rules on health and safety at work and provides information on health and safety at work.^[67] The result of each inspection is made public on the web pages of the Danish Working Environment Authority so that the general public, current and prospective employees, customers and other stakeholders can inform themselves about whether a given organization has passed the inspection, should they wish to do so.^[68]

Spain

In Spain, occupational safety and health is regulated by the Spanish Act on Prevention of Labour Risks. The Ministry of Employment and Social Security is the authority responsible for issues relating to labour environment.^[69] The National Institute for Labour Safety and Hygiene is the technical public Organization specialized in occupational safety and health.^[70]

Sweden

In Sweden, occupational safety and health is regulated by the Work Environment Act. The Swedish Work Environment Authority is the government agency responsible for issues relating to the working environment. The agency should work to disseminate information and furnish advice on OSH, has a mandate to carry out inspections, and a right to issue stipulations and injunctions to any non-compliant employer.^[71]

United Kingdom

In the UK, health and safety legislation is drawn up and enforced by the Health and Safety Executive and local authorities (the local council) under the Health and Safety at Work etc. Act 1974^[72][73] (HASAWA). HASAWA introduced (section 2) a general duty on an employer to ensure, so far as is reasonably practicable, the health, safety and welfare at work of all his employees; with the intention of giving a legal framework supporting 'codes of practice' not in themselves having legal force but establishing a strong presumption as to what was reasonably practicable (deviations from them could be justified by appropriate risk assessment). The previous reliance on detailed prescriptive rule-setting was seen as having failed to respond rapidly enough to technological change, leaving new technologies potentially un-regulated or inappropriately regulated.^[74][75] HSE has continued to make some regulations giving absolute duties (where something must be done with no 'reasonable practicability' test) but in the UK the regulatory trend is away from prescriptive rules, and towards 'goal setting' and risk assessment. Recent major changes to the laws governing asbestos and fire safety management embrace the concept of risk assessment. The other key aspect of the UK legislation is a statutory mechanism for worker involvement through elected health and safety representatives and health and safety committees. This followed a similar approach in Scandinavia, and that approach has since been adopted in Australia, Canada, New Zealand and Malaysia, for example.

For the UK, the government organisation dealing with occupational health has been the Employment Medical Advisory Service but in 2014 a new occupational health organisation - the Health and Work Service - was created to provide advice and assistance to employers in order to get back to work employees on long-term sick-leave.^[76] The service, funded by government, will offer medical assessments and treatment plans, on a voluntary basis, to people on long term absence from their employer; in return, the government will no longer foot the bill for Statutory Sick Pay provided by the employer to the individual.

India

In India, the Labour Ministry formulates national policies on occupational safety and health in factories and docks with advice and assistance from Directorate General of Factory Advice Service and Labour Institutes (DGFASLI), and enforces its Policies through inspectorates of factories and inspectorates of dock safety.^[77] DGFASLI is the technical arm of the Ministry of Labour & Employment, Government of India and advises the factories on various problems concerning safety, health, efficiency and well - being of the persons at work places.^[77] The DGFASLI provides technical support in formulating rules, conducting occupational safety surveys and also for conducting occupational safety training programs.^[78]

Malaysia

In Malaysia, the Department of Occupational Safety and Health (DOSH) under the Ministry of Human Resource is responsible to ensure that the safety, health and welfare of workers in both the public and private sector is upheld. DOSH is responsible to enforce the Factories and Machinery Act 1967 and the Occupational Safety and Health Act 1994.

People's Republic of China

Hardware stores in China specializing in safety equipment

In the People's Republic of China, the Ministry of Health is responsible for occupational disease prevention and the State Administration of Work Safety for safety issues at work. On the provincial and municipal level, there are Health Supervisions for occupational health and local bureaus of Work Safety for safety. The "Occupational Disease Control Act of PRC" came into force on May 1, 2002.^[79] and Work safety Act of PRC on November 1, 2002.^[80] The Occupational Disease Control Act is under revision. The prevention of occupational disease is still in its initial stage compared with industrialised countries such as the US or UK.

Singapore

In Singapore, the Ministry of Manpower operates various checks and campaigns against unsafe work practices, such as when working at height, operating cranes and in traffic management. Examples include Operation Cormorant and the Falls Prevention Campaign.^[81]

South Africa

In South Africa the Department of Labour is responsible for occupational health and safety inspection and enforcement in commerce and industry apart from mining and energy production, where the Department of Mineral Resources is responsible.

The main statutory legislation on Health and Safety in the jurisdiction of the Department of Labour is Act No. 85 of 1993: Occupational Health and Safety Act as amended by Occupational Health and Safety Amendment Act, No. 181 Of 1993.

Regulations to the OHS Act include:

• General Administrative Regulations, 2003^[82]
• Certificate of Competency Regulations, 1990^[83]
• Construction Regulations, 2003
• Diving Regulations 2009^[84]
• Driven Machinery Regulations, 1988^[85]
• Environmental Regulations for Workplaces, 1987^[86]
• General Machinery regulations, 1988^[87]
• General Safety Regulations, 1986^[88]
• Noise induced hearing loss regulations, 2003^[89]
• Pressure Equipment Regulations, 2004

Taiwan

In Taiwan, the Occupational Safety and Health Administration of the Ministry of Labor is in charge of occupational safety and health.^[90] The matter is governed under the Occupational Safety and Health Act.^[91]

2007,official release the document TOSHMS (Taiwan Occupational Safety and Health Management System),which defined the basic rule about occupational safety standard.^[92]

United States

In the United States, President Richard Nixon signed the Occupational Safety and Health Act into law on December 29, 1970. The act created the three agencies that administer it. They include the Occupational Safety and Health Administration, National Institute for Occupational Safety and Health, and the Occupational Safety and Health Review Commission.^[93] The act authorized the Occupational Safety and Health Administration (OSHA) to regulate private employers in the 50 states, the District of Columbia, and territories.^[94] The Act establishing it includes a general duty clause (29 U.S.C. § 654, 5(a)) requiring an employer to comply with the Act and regulations derived from it, and to provide employees with "employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees."

OSHA was established in 1971 under the Department of Labor. It has headquarters in Washington, DC and ten regional offices, further broken down into districts, each organized into three sections; compliance, training, and assistance. Its stated mission is to assure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education and assistance.^[95] The original plan was for OSHA to oversee 50 state plans with OSHA funding 50% of each plan. Unfortunately it has not worked out that way. There are currently 26 approved state plans (4 cover only public employees)^[48] and no other states want to participate. OSHA manages the plan in the states not participating.^[48]

OSHA develops safety standards in the Code of Federal Regulation and enforces those safety standards through compliance inspections conducted by Compliance Officers; enforcement resources are focussed on high-hazard industries. Worksites may apply to enter OSHA's Voluntary Protection Program (VPP); a successful application leads to an on-site inspection ; if this is passed the site gains VPP status and OSHA no longer inspect it annually nor (normally) visit it unless there is a fatal accident or an employee complaint until VPP revalidation (after 3–5 years)^[48](VPP sites have injury and illness rates less than half the average for their industry).

It has 73 specialists in local offices to provide tailored information and training to employers and employees at little or no cost^[4] Similarly OSHA produces a range of publications, provides advice to employers and funds consultation services available for small businesses.

OSHA's Alliance Program enables groups committed to worker safety and health to work with it to develop compliance assistance tools and resources, share information with workers and employers, and educate them about their rights and responsibilities. OSHA also has a Strategic Partnership Program that zeros in on specific hazards or specific geographic areas.^[48] OSHA manages Susan B. Harwood grants to nonprofit companies to train workers and employers to recognize, avoid, and prevent safety and health hazards in the workplace. Grants focus on small business, hard-to-reach workers and high-hazard industries.

The National Institute of Occupational Safety and Health (NIOSH), created under the same act, works closely with OSHA and provides the research behind many of OSHA's regulations and standards.^[96]

Professional roles and responsibilities

The roles and responsibilities of OSH professionals vary regionally, but may include evaluating working environments, developing, endorsing and encouraging measures that might prevent injuries and illnesses, providing OSH information to employers, employees, and the public, providing medical examinations, and assessing the success of worker health programs.

Europe

In Norway, the main required tasks of an occupational health and safety practitioner include the following:

• Systematic evaluations of the working environment
• Endorsing preventative measures which eliminate causes of illnesses in the workplace
• Providing information on the subject of employees’ health
• Providing information on occupational hygiene, ergonomics, and environmental and safety risks in the workplace^[97]

In the Netherlands, the required tasks for health and safety staff are only summarily defined and include the following:

• Providing voluntary medical examinations
• Providing a consulting room on the work environment to the workers
• Providing health assessments (if needed for the job concerned)^[98]

‘The main influence of the Dutch law on the job of the safety professional is through the requirement on each employer to use the services of a certified working conditions service to advise them on health and safety’.^[98] A ‘certified service’ must employ sufficient numbers of four types of certified experts to cover the risks in the organisations which use the service:

• A safety professional
• An occupational hygienist
• An occupational physician
• A work and organisation specialist.^[98]

In 2004, 37% of health and safety practitioners in Norway and 14% in the Netherlands had an MSc; 44% had a BSc in Norway and 63% in the Netherlands; and 19% had training as an OSH technician in Norway and 23% in the Netherlands.^[98]

USA

Leather craftsman gloves, safety goggles, and a properly fitted hardhat are crucial for proper safety in a construction environment.

The main tasks undertaken by the OHS practitioner in the USA include:

• Develop processes, procedures, criteria, requirements, and methods to attain the best possible management of the hazards and exposures that can cause injury to people, and damage property, or the environment;
• Apply good business practices and economic principles for efficient use of resources to add to the importance of the safety processes;
• Promote other members of the company to contribute by exchanging ideas and other different approaches to make sure that every one in the corporation possess OHS knowledge and have functional roles in the development and execution of safety procedures;
• Assess services, outcomes, methods, equipment, workstations, and procedures by using qualitative and quantitative methods to recognise the hazards and measure the related risks;
• Examine all possibilities, effectiveness, reliability, and expenditure to attain the best results for the company concerned^[99]

Knowledge required by the OHS professional in USA include:

• Constitutional and case law controlling safety, health, and the environment
• Operational procedures to plan/develop safe work practices
• Safety, health and environmental sciences
• Design of hazard control systems (i.e. fall protection, scaffoldings)
• Design of recordkeeping systems that take collection into account, as well as storage, interpretation, and dissemination

Differences between countries and regions

Because different countries take different approaches to ensuring occupational safety and health, areas of OSH need and focus also vary between countries and regions. Similar to the findings of the ENHSPO survey conducted in Australia, the Institute of Occupational Medicine in the UK found that there is a need to put greater emphasis on work-related illness in the UK.^[101] In contrast, in Australia and the USA a major responsibility of the OHS professional is to keep company directors and managers aware of the issues that they face in regards to occupational health and safety principles and legislation. However, in some other areas of Europe, it is precisely this which has been lacking: “Nearly half of senior managers and company directors do not have an up-to-date understanding of their health and safety-related duties and responsibilities.”^[102]

Identifying safety and health hazards

Hazards, risks, outcomes

The terminology used in OSH varies between countries, but generally speaking:

• A hazard is something that can cause harm if not controlled.
• The outcome is the harm that results from an uncontrolled hazard.
• A risk is a combination of the probability that a particular outcome will occur and the severity of the harm involved.^[103]

“Hazard”, “risk”, and “outcome” are used in other fields to describe e.g. environmental damage, or damage to equipment. However, in the context of OSH, “harm” generally describes the direct or indirect degradation, temporary or permanent, of the physical, mental, or social well-being of workers. For example, repetitively carrying out manual handling of heavy objects is a hazard. The outcome could be a musculoskeletal disorder (MSD) or an acute back or joint injury. The risk can be expressed numerically (e.g. a 0.5 or 50/50 chance of the outcome occurring during a year), in relative terms (e.g. "high/medium/low"), or with a multi-dimensional classification scheme (e.g. situation-specific risks).

Hazard identification

Hazard identification or assessment is an important step in the overall risk assessment and risk management process. It is where individual work hazards are identified, assessed and controlled/eliminated as close to source (location of the hazard) as reasonably as possible. As technology, resources, social expectation or regulatory requirements change, hazard analysis focuses controls more closely toward the source of the hazard. Thus hazard control is a dynamic program of prevention. Hazard-based programs also have the advantage of not assigning or implying there are "acceptable risks" in the workplace. A hazard-based program may not be able to eliminate all risks, but neither does it accept "satisfactory" – but still risky – outcomes. And as those who calculate and manage the risk are usually managers while those exposed to the risks are a different group, workers, a hazard-based approach can by-pass conflict inherent in a risk-based approach.

The information that needs to be gathered from sources should apply to the specific type of work from which the hazards can come from. As mentioned previously, examples of these sources include interviews with people who have worked in the field of the hazard, history and analysis of past incidents, and official reports of work and the hazards encountered. Of these, the personnel interviews may be the most critical in identifying undocumented practices, events, releases, hazards and other relevant information. Once the information is gathered from a collection of sources, it is recommended for these to be digitally archived (to allow for quick searching) and to have a physical set of the same information in order for it to be more accessible. One innovative way to display the complex historical hazard information is with a historical hazards identification map, which distills the hazard information into an easy to use graphical format.

Risk assessment

Modern occupational safety and health legislation usually demands that a risk assessment be carried out prior to making an intervention. It should be kept in mind that risk management requires risk to be managed to a level which is as low as is reasonably practical.

This assessment should:

• Identify the hazards
• Identify all affected by the hazard and how
• Evaluate the risk
• Identify and prioritize appropriate control measures

The calculation of risk is based on the likelihood or probability of the harm being realized and the severity of the consequences. This can be expressed mathematically as a quantitative assessment (by assigning low, medium and high likelihood and severity with integers and multiplying them to obtain a risk factor), or qualitatively as a description of the circumstances by which the harm could arise.

The assessment should be recorded and reviewed periodically and whenever there is a significant change to work practices. The assessment should include practical recommendations to control the risk. Once recommended controls are implemented, the risk should be re-calculated to determine of it has been lowered to an acceptable level. Generally speaking, newly introduced controls should lower risk by one level, i.e., from high to medium or from medium to low.

Contemporary developments

On an international scale, the World Health Organization (WHO) and the International Labour Organization (ILO) have begun focusing on labour environments in developing nations with projects such as Healthy Cities.^[104] Many of these developing countries are stuck in a situation in which their relative lack of resources to invest in OSH leads to increased costs due to work-related illnesses and accidents. As a 2007 Factsheet from the European Agency for Safety and Health at Work states: "Countries with less developed OSH systems spend a far higher percentage of GDP on work-related injury and illness – taking resources away from more productive activities . . . The ILO estimates that work-related illness and accidents cost up to 10% of GDP in Latin America, compared with just 2.6% to 3.8% in the EU."^[105] There is continued use of asbestos, a notorious hazard, in some developing countries. So asbestos-related disease is, sadly, expected to continue to be a significant problem well into the future.

Nanotechnology

A nanomaterial containment hood, an example of an engineering control used to protect workers handling them on a regular basis.

Nanotechnology is an example of a new, relatively unstudied technology. A Swiss survey of one hundred thirty eight companies using or producing nanoparticulate matter in 2006 resulted in forty completed questionnaires. Sixty five per cent of respondent companies stated they did not have a formal risk assessment process for dealing with nanoparticulate matter.^[106] Nanotechnology already presents new issues for OSH professionals that will only become more difficult as nanostructures become more complex. The size of the particles renders most containment and personal protective equipment ineffective. The toxicology values for macro sized industrial substances are rendered inaccurate due to the unique nature of nanoparticulate matter. As nanoparticulate matter decreases in size its relative surface area increases dramatically, increasing any catalytic effect or chemical reactivity substantially versus the known value for the macro substance. This presents a new set of challenges in the near future to rethink contemporary measures to safeguard the health and welfare of employees against a nanoparticulate substance that most conventional controls have not been designed to manage.^[107]

Education

There are multiple levels of training applicable to the field of occupational safety and health (OSH). Programs range from individual non-credit certificates, focusing on specific areas of concern, to full doctoral programs. The University of Southern California was one of the first schools in the US to offer a Ph.D. program focusing on the field. Further, multiple master's degree programs exist, such as that of the Indiana State University who offer a master of science (MS) and a master of arts (MA) in OSH. Graduate programs are designed to train educators, as well as, high-level practitioners. Many OSH generalists focus on undergraduate studies; programs within schools, such as that of the University of North Carolina's online Bachelor of Science in Environmental Health and Safety, fill a large majority of hygienist needs. However, smaller companies often don’t have full-time safety specialists on staff, thus, they appoint a current employee to the responsibility. Individuals finding themselves in positions such as these, or for those enhancing marketability in the job-search and promotion arena, may seek out a credit certificate program. For example, the University of Connecticut's online OSH Certificate,^[108] provides students familiarity with overarching concepts through a 15-credit (5-course) program. Programs such as these are often adequate tools in building a strong educational platform for new safety managers with a minimal outlay of time and money. Further, most hygienists seek certification by organizations which train in specific areas of concentration, focusing on isolated workplace hazards. The American Society for Safety Engineers (ASSE), American Board of Industrial Hygiene (ABIH), and American Industrial Hygiene Association (AIHA) offer individual certificates on many different subjects from forklift operation to waste disposal and are the chief facilitators of continuing education in the OSH sector. In the U.S. the training of safety professionals is supported by National Institute for Occupational Safety and Health through their NIOSH Education and Research Centers. In Australia, training in OSH is available at the vocational education and training level, and at university undergraduate and postgraduate level. Such university courses may be accredited by an Accreditation Board of the Safety Institute of Australia. The Institute has produced a Body of Knowledge^[109] which it considers is required by a generalist safety and health professional, and offers a professional qualification based on a four-step assessment.

World Day for Safety and Health at Work

On April 28 The International Labour Organisation celebrates "World Day for Safety and Health"^[110] to raise awareness of safety in the workplace. Occurring annually since 2003,^[111] each year it focuses on a specific area and bases a campaign around the theme.^[112]
