Did You Know?

The origin of "hazmat" is clear enough - it was formed by combining the first three letters of each of two words: "hazardous" and "material." The word hazmat is fairly young, first appearing in print in 1980. Although it is a noun, "hazmat" tends to be used attributively, meaning that it often appears in sentences before another noun as if it were performing the duties of an adjective (as in "hazmat team" and "hazmat worker").
