Hazwoper, or Hazardous Waste Operations and Emergency Response, standard has been issued by OSHA for covering all those workers who face exposure to harmful and toxic exposure at their workplaces. The Occupational Safety and Health Administration training has established certain training requirements for all those workers who make direct and frequent contact with hazardous materials and substances.

Those who are employed to remove hazardous waste substances and face potential health hazards at their work site have to complete the 40 hour, off site training course for certification. The course consists of online training. However, employees have to complete at least three days of practical, supervised training on the field. The topics covered in this training are on site hazards, different ways to reduce risk, use of protective gear and recognizing the different signs of exposure.

The personnel appointed for supervising also need to complete the 40 hour training for certification. They take up the 8 hour course which covers topics like employer specific programs, training and protecting employees, monitoring hazards and overseeing health and safety.

Those workers who have been certified by Hazwoper need to complete at least 8 hours of annual refresher training. This training can be completed in parts through self paced online trainings.
