The following are examples of hazardous wastes: ignitable wastes, corrosive wastes, and reactive wastes. Provide a brief description of each.
What will be an ideal response?
Ignitable wastes burn readily. These materials have a flash point of less than 140F. Automotive products such as cleaning solvents, paint solvents, degreasers, and gasoline are examples of ignitable materials.
Corrosive wastes burn the skin or corrode metals or other materials. They have a pH of lower than 2 or higher than 12.5. Examples include rust removers and acid or alkaline cleaning liquids.
Reactive wastes are unstable and react rapidly or violently when combined. A good example of a reactive waste is the combination of ammonia and bleach, which forms phosgene gas (nerve gas). There are hardly any reactive wastes used in the automotive industry. Acetylene (used in gas welding) is an example of a reactive substance.
