What is the first priority for the first crew at a suspected hazmat release?

  1. Find and stop the leak at its source
  2. Wash the product away with a hoseline
  3. Isolate the area and keep people out
  4. Collect a sample of the product
Show the answer

C. Isolate the area and keep people out

Isolation and denial of entry keeps more people from becoming victims and is done before anything else. Stopping the leak may come later, by people trained and equipped for it; flushing can spread the product.

Responders should approach a hazardous materials incident from

  1. Uphill and downwind
  2. Uphill and upwind
  3. Downhill and upwind
  4. Downhill and downwind
Show the answer

B. Uphill and upwind

Vapors drift downwind and liquids and heavy gases flow downhill, so the safe approach is from uphill and upwind. Any downhill or downwind position can put responders in the product's path.
