To qualify as hazardous waste, a waste must have which of the following characteristics? Choose the correct answer from the options given below.
- 1. Ignitability
- 2. Corrosivity
- 3. Reactivity
- 4. Toxicity
- 5. Radioactivity
A1, 3 and 4 only
B2, 3 and 4 only
C1, 2, 3 and 5 only
D1, 2, 3, 4 and 5 ✓ Correct
Correct answer: (D) 1, 2, 3, 4 and 5 — All five characteristics apply, so the answer is 1, 2, 3, 4 and 5.
Explanation
★All five characteristics apply, so the answer is 1, 2, 3, 4 and 5.
★Hazardous waste can harm human health or the environment.
★Ignitability means it can readily catch fire.
★Corrosivity means it can corrode materials, and reactivity means it is chemically unstable.
★Toxicity means it is poisonous, and radioactivity means it emits harmful radiation.
★So ignitability, corrosivity, reactivity, toxicity and radioactivity are all characteristics.
