Entry-level HAZWOPER jobs include a variety of positions that provide Hazardous Waste Operations and Emergency Response services. Common positions include roles like air monitoring, water treatment system operator, and chemical technician. HAZWOPER is usually not a job title in its own right. Instead, the name refers to an OSHA training program that is mandatory for some jobs that work with hazardous materials. As part of this, you may participate in hazard cleanup and removal efforts, provide training to other people who work around hazards, or monitor the level of toxins in the local environment. HAZWOPER jobs often involve wearing personal protective equipment and working with particularly dangerous substances.
