  1. What are the characteristics and parameters of Characteristic Hazardous Waste?

The four characteristics of hazardous waste are;Ignitability, if a waste burns at a flash point of less than 60 0 C such as waste oils and used solvents. Corrosivity are wastes with pH below or equivalent to 2.0 and larger than or equivalent to 12.5 are acidic and corrode metals such as battery acid. Reactivity is when the reactive waste reacts violently with water, forms explosions, generates toxic gases and fumes when reacted with waters such as metallic sodium potassium while Toxicity are harmful waste if absorbed. Therefore, if the waste fails toxicity characteristics leaching procedure lab test for given 40 parameters is regarded to be toxic and includes lead or mercury metals.
