SUBJECT 4 · POST-CRASH & TRIAGE

When corrosive substances catch fire, they cannot be extinguished by spraying directly with a high-pressure water jet.

A
True
B
False
ANSWER · A
When inorganic or organic corrosive substances burn directly, except those that react with water, large amounts of water are usually fine, but use mist water — do not spray high-pressure water jets directly, to prevent splashing droplets from burning rescuers. Liquid corrosives should be covered and absorbed with dry sand or soil, then swept away and rinsed with water. For large spills, neutralize with dilute acid or alkali, taking care to prevent violent reactions. When rinsing the leak site, only pour or spray slowly with mist water to prevent splashing. The statement is correct.
