Cost: $95 per person

Do You Need to Take an 8 Hour HAZWOPER Refresher Course?

National Environmental Trainer’s (NET) online HAZWOPER 8-hour annual refresher course is for anyone who needs to keep their 24-Hour HAZWOPER or 40-Hour general site worker certification current in compliance with OSHA 29 CFR 1910.120.

You’ll need to take the refresher on or before the anniversary date of your initial 24- or 40-hour HAZWOPER training. If you have missed a refresher training, attend the next available course. You may need to repeat the initial 24- or 40-hour HAZWOPER training if a substantial amount of time has passed since you took the refresher.

The grace period for missing a refresher must be determined by your employer. Ultimately, all employees must be trained sufficiently to be safe while performing their job duties.

Course Content

When you complete NET’s 8-hour online HAZWOPER refresher training, you will have re-certification as a 24-Hour HAZWOPER or 40-Hour general site worker. This course is to be completed as your annual refresher training after having previously completed the 24- or 40-hour HAZWOPER training.

Additionally, you’ll know the laws and regulations as they relate to hazardous substances, the chemical properties that cause harm to people, the environment and property, and the toxicology of various chemicals on the human body.

The 8-hour course also refreshes your understanding of respiratory protection relating to contaminated site cleanup, the four levels of PPE used in contaminated site cleanup and emergency response and how to implement a proper decontamination sequence.

Physical and On Site Requirements

While NET’s training course is very comprehensive, additional site-specific training must be taken for certain hazardous materials/environments that may be encountered at different sites. This is an employer obligation.
