Multiple choice

What is the definition of ignitability in the context of hazardous waste?

  1. The ability of a waste to catch fire and burn easily.

  2. The ability of a waste to produce toxic gases when burned.

  3. The ability of a waste to corrode metal.

  4. The ability of a waste to react violently with water.

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ignitability is the ability of a waste to catch fire and burn easily. This property is important because it can pose a fire hazard if the waste is not properly managed.

Multiple choice
