PPE by usage

Combat

Gear for defense against ballistic weapons are commonly worn by military and law enforcement personnel.

A shield is held in the hand or arm. Its purpose is to intercept attacks, either by stopping projectiles such as arrows or by glancing a blow to the side of the shield-user. Shields vary greatly in size, ranging from large shields that protect the user's entire body to small shields that are mostly for use in hand-to-hand combat. Shields also vary a great deal in thickness; whereas some shields were made of thick wooden planking, to protect soldiers from spears and crossbow bolts, other shields were thinner and designed mainly for glancing blows away (such as a sword blow). In prehistory, shields were made of wood, animal hide, or wicker. In antiquity and in the Middle Ages, shields were used by foot soldiers and mounted soldiers. Even after the invention of gunpowder and firearms, shields continued to be used. In the 18th century, Scottish clans continued to use small shields, and in the 19th century, some non-industrialized peoples continued to use shields. In the 20th and 21st century, shields are used by military and police units that specialize in anti-terrorist action, hostage rescue, and siege-breaching.

Torso

Ballistic vest.

A ballistic vest helps absorb the impact from firearm-fired projectiles and shrapnel from explosions, and is worn on the torso. Soft vests are made from many layers of woven or laminated fibers and can be capable of protecting the wearer from small caliber handgun and shotgun projectiles, and small fragments from explosives such as hand grenades.

Metal or ceramic plates can be used with a soft vest, providing additional protection from rifle rounds, and metallic components or tightly-woven fiber layers can give soft armor resistance to stab and slash attacks from a knife. Soft vests are commonly worn by police forces, private citizens and private security guards or bodyguards, whereas hard-plate reinforced vests are mainly worn by combat soldiers, police tactical units and hostage rescue teams.

Modern body armor may combine a ballistic vest with other items of protective clothing, such as a combat helmet. Vests intended for police and military use may also include ballistic shoulder and side protection armor components, and bomb disposal officers wear heavy armor and helmets with face visors and spine protection.

A combat helmet are among the oldest forms of personal protective equipment, and are known to have been worn by the Assyrians around 900BC, followed by the ancient Greeks and Romans, throughout the Middle Ages, and up to the end of the 1600s by many combatants.[1] Their materials and construction became more advanced as weapons became more and more powerful. Initially constructed from leather and brass, and then bronze and iron during the Bronze and Iron Ages, they soon came to be made entirely from forged steel in many societies after about 950AD.[2] At that time, they were purely military equipment, protecting the head from cutting blows with swords, flying arrows, and low-velocity musketry. Today's militaries often use high-quality helmets made of ballistic materials such as Kevlar and Aramid, which have excellent bullet and fragmentation stopping power. Some helmets also have good non-ballistic protective qualities, though many do not.[3] Non-ballistic injuries may be caused by many things, such as concussive shockwaves from explosions, physical attacks, motor vehicle accidents, or falls.[4]

A ballistic face mask, is designed to protect the wearer from ballistic threats. Ballistic face masks are usually made of kevlar or other bullet resistant materials and the inside of the mask may be padded for shock absorption, depending on the design. Due to weight restrictions, protection levels range only up to NIJ Level IIIA.

Respirator

A gas mask is worn over the face to protect the wearer from inhaling "airborne pollutants" and toxic gases. The mask forms a sealed cover over the nose and mouth, but may also cover the eyes and other vulnerable soft tissues of the face. Airborne toxic materials may be gaseous or particulate. Many gas masks include protection from both types. During riots where tear gas or CS-gas is employed by riot police, gas masks are commonly used by police and rioters alike.

Limbs

Protection of limbs from bombs is provided by a bombsuit.

Sports

Limbs

A pair of fingerless cycling gloves.

Gloves are frequently used to keep the hands warm, a function that is particularly necessary when cycling in cold weather. The hands are also relatively inactive, and do not have a great deal of muscle mass, which also contributes to the possibility of chill. Gloves are therefore vital for insulating the hands from cold, wind, and evaporative cooling. Putting a hand out to break a fall is a natural reaction, however, the hands are one of the more difficult parts of the body to repair. There is little or no spare skin, and immobilising the hands sufficiently to promote healing involves significant inconvenience to the patient. Fingerless gloves, have a lightly padded palm of leather (natural or synthetic), gel or other material. Full-finger gloves are useful in winter, when real warmth is not an issue. These are also generally waterproof but will become soggy in heavy rain.

Construction

Head

A hard hat is a type of helmet predominantly used in workplace environments, such as construction sites, to protect the head from injury by falling objects, impact with other objects, debris, bad weather and electric shock. Inside the helmet is a suspension that spreads the helmet's weight over the top of the head. It also provides a space of approximately 3 cm (1.2 inch) between the helmet's shell and the wearer's head so that if an object strikes the shell, the impact is less likely to be transmitted directly to the skull. Rigid plastic has been the most common material.

Respiratory system

A half face particulate mask.

A respirator is designed to protect the wearer from inhaling harmful dusts, fumes, vapors, and/or gases. Respirators come in a wide range of types and sizes used by the military, private industry, and the public. Respirators range from cheaper, single-use, disposable masks to reusable models with replaceable cartridges. There are two main categories: the air-purifying respirator, which forces contaminated air through a filtering element, and the air-supplied respirator, in which an alternate supply of fresh air is delivered. Within each category, different techniques are employed to reduce or eliminate noxious airborne contents. The term respirator in the hospital setting refers to the N95 filtering face piece masks that are commonly used to care for patients with Tuberculosis. There was much controversy over the use of these masks during the H1N1 outbreak of 2009.[5]

Full protective garments

Protective suit is an umbrella term for any suit or clothing which protects the wearer. Any specific design of suit may offer protection against biological and chemical chemical agents, particle radiation (alpha) and/or radiation (delta and gamma), and may offer flash protection in the case of bomb disposal suits. Most forms of industrial clothing are protective clothing. Personal protective equipment includes:

Complete suits

The word "chemsuit" is sometimes used to mean a real chemical-protection suit, as well as fictional.
