HAZMAT

HAZMAT is short for hazardous materials: substances that can harm people, property or the environment when they spill, leak, burn or are released. The term covers chemicals, fuels, compressed gases, corrosives, radioactive materials and biological agents. HAZMAT also names the system for marking and shipping these materials safely, and the trained crews who respond when something goes wrong.

Preppers meet the term in two places. The first is the highway, rail line or plant near home, where a HAZMAT incident can bring an order to evacuate or shelter in place. The second is the garage and the cabinet under the sink, where bleach, pool chemicals, fuel and pesticides sit on the shelf. Knowing what HAZMAT means helps you read an emergency alert quickly and store your own supplies with care.
