PHRASE ORIGIN

Hazmat is an American abbreviation formed from the opening parts of hazardous materials. It appeared in the United States during the second half of the twentieth century and was established by the 1970s. It was initially associated particularly with the storage, transport and emergency handling of dangerous substances.

The word is an example of a clipped compound: two shortened words are fitted together and pronounced as one, rather like sitcom from situation comedy. It may be written hazmat, HazMat or, particularly in official contexts, HAZMAT.

Adding suit produced the transparent compound hazmat suit. The name can be slightly misleading, however: there’s no single universal suit. The appropriate clothing depends on whether the danger comes from gases, liquids, particles, radiation or biological agents—and whether breathing equipment is required.

THE DANGER INSIDE THE SUIT

A suit designed to keep danger out can create a new danger inside.

Chemical-resistant clothing often prevents sweat from evaporating. Add gloves, boots, a hood and breathing equipment, and the wearer is doing physical work inside something resembling a sealed plastic greenhouse. Body heat rises, vision may mist up and simple movements demand more effort.

A 1987 study of workers wearing protective suits found that the clothing could impose heat stress comparable to adding roughly 6°C to 11°C to the surrounding conditions. That’s why emergency teams don’t simply send someone into a contaminated area and wait. They plan work periods, rest breaks, hydration and medical observation.

Cooling can be surprisingly technical. Some workers wear vests containing ice packs or circulating chilled water. Others use air-cooled garments. Yet cooling equipment adds weight, bulk and another possible point of failure.

Protection also comes in levels. Under the American system, Level A provides the greatest skin, eye and respiratory protection. Its fully encapsulating suit and independent air supply may look reassuringly invincible. It isn’t. The person inside still has limited air, restricted movement and a body steadily producing heat.

A hazmat suit is therefore not armour against everything; it’s a carefully managed temporary refuge.
