Step 1: Characteristics of hazardous waste as per rules. According to the Hazardous Waste (Management and Handling) Rules, 2016, a waste is classified as “characteristic” hazardous waste if it exhibits any of the following characteristics:
Ignitability: The waste is flammable or combustible under standard conditions.
Reactivity: The waste reacts violently with water, air, or other substances, potentially causing explosions or toxic gas releases.
Toxicity: The waste contains toxic substances that pose a risk to human health or the environment when improperly managed.
Step 2: Analyze the options.
Ignitability: Correct, as it is one of the characteristics of hazardous waste.
Reactivity: Correct, as it is a key property defining hazardous waste.
Radioactivity: Incorrect, as radioactive waste is regulated separately under specific guidelines.
Toxicity: Correct, as toxic substances in waste contribute to its hazardous classification.
