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

Explanation

A hazardous waste is defined by dangerous physical or chemical traits, and all five listed here are counted.

Statement 1 is right: ignitability denotes wastes that catch fire easily.

Statement 2 is right: corrosivity denotes strongly acidic or alkaline wastes that eat into materials.

Statement 3 is right: reactivity denotes unstable wastes that can explode or release toxic gas.

Statement 4 is right: toxicity denotes wastes that poison living things or leach harmful substances.

Statement 5 is right here: radioactivity denotes wastes emitting harmful ionising radiation.

The first four form the core regulatory set, with radioactive waste often handled under special rules.
