Hazardous waste technicians dispose of materials that have been in contact with or are ignitable, corrosive, reactive, toxic or a combination of the aforementioned hazardous traits. They remove the waste from industrial facilities or households and transport them to a treatment facility to ensure they are treated and disposed of according to regulations. They may also advise on the proper treatment of hazardous waste, and aid in the clean-up of hazardous waste spills.
