Why does hazardous waste require special handling?

Answer: It's harmful to humans, so touching it could cause disease and injury. In order to properly get rid of it you need specific gear (such as protective goggles, gloves, suits, etc) in order to avoid harm.

A hazardous waste is a special type of waste because it cannot be disposed of by common means like other by-products of our everyday lives. Depending on the physical state of the waste, treatment and solidification processes might be required.
