Do You Need to Take the OSHA 40-Hour HAZWOPER Training Course?

The 40-Hour HAZWOPER training course meets the requirements outlined in OSHA’s Hazardous Waste Operations and Emergency Response (HAZWOPER) 29 CFR 1910.120(e) standard. This course prepares workers to operate safely in situations with hazardous substances. Typical locations include:

  • Voluntary or required clean-up operations on hazardous waste sites
  • Clean-up operations on sites covered by the Resource Conservation and Recovery Act (RCRA)
  • Operations conducted at treatment, storage, and disposal (TSD) facilities
  • Emergency response operations involving potential release of hazardous substances

40-Hour HAZWOPER training is intended for workers facing high risk of exposure on the job at levels at or above OSHA’s permissible exposure limits (PELs). HAZWOPER training is required for all workers at contaminated sites. However, workers that are facing less exposure risk can take the 24-Hour HAZWOPER training. All workers must complete the 8-Hour HAZWOPER Refresher each year, regardless of which initial training course they completed.

What to Expect in Online 40-Hour HAZWOPER Training

The course has been fully revised and reorganized and features exceptional content containing current research, standards, and technology. The self-paced training is interactive and fully narrated with thorough explanations and check point questions throughout to ensure comprehension.

Upon completion, learners will understand OSHA’s 29 CFR 1910.120(e) standard and how to stay safe when handling dangerous chemicals or responding to emergencies involving hazardous waste. The course features a Hands-On Simulator that enables learners to participate in three virtual scenarios of donning and doffing Level A, Level B, and Level C personal protective equipment (PPE).

Upon completion of the self-study modules, learners take a final examination to earn their certification. After successfully passing the examination, learners can download a certificate of completion and will receive a copy by email. The certificate can be shared with employers immediately after completing the training.

Course Objectives

After completing NET’s online 40-Hour HAZWOPER training, learners will:

  • Be certified as a HAZWOPER 40 General Site Worker, meeting requirements of 29 CFR 1910.120(e) and other applicable regulations.
  • Understand hazardous substances and materials, workplace risks, and the health effects of hazardous materials to the human body.
  • Have an up-to-date understanding of regulations and statutes relating to HAZWOPER operations and the limitations of the various levels of certifications, such as OSHA’s Hazard Communication Standard, the Globally Harmonized System of Classification and Labeling of Chemicals (GHS), site characterization, and medical surveillance programs.
  • Know how to prepare a site safety and health plan and a job hazard analysis that minimizes risk from hazardous materials.
  • Be able to identify hazardous substances, including the use of the Department of Transportation (DOT) labeling system, National Fire Protection Association (NFPA) 704 placard system, Hazardous Materials Information System (HMIS), container profiles, the Globally Harmonized System (GHS), and Safety Data Sheets (SDSs).
  • Know how to select and use (don and doff) proper personal protective equipment (PPE), including Level A, B, and C protection using NET’s HAZWOPER Hands-on Simulator®.
  • Understand basic hazardous materials terminology such as vapor density, specific gravity, pH, TLV/TWA, PEL, STEL, IDLH, flammability range, L.E.L./U.E.L., combustible, flammable, flash point, and auto-ignition temperature.
  • Understand the concepts of decontamination and their importance in hazardous materials operations.
  • Know how to enter confined spaces and ensure safety during operations in these spaces.
  • Know the methods to contain and control spills at work sites.

Physical and On Site Requirements

To become HAZWOPER certified, learners must be physically able to wear a self-contained breathing apparatus (SCBA) and a fully encapsulating suit, either Level A or Level B personal protective equipment (PPE). The weight of these suits varies but is typically 30 to 40 pounds. The suits also vary in type, and maneuverability on a work site can be difficult.

This course covers the 40 hours of initial training. Final certification requires a minimum of three days of actual field experience under the direct supervision of a trained, experienced supervisor.

Plan States (approved by U.S. OSHA) must have standards at least as stringent as the Federal 40-Hour HAZWOPER training requirements. These Plan States may have additional training requirements.


What is 40-hour HAZWOPER training?

  • The 40-Hour HAZWOPER course is designed for a person who works in an environment where there is a potential for exposure to hazardous substances at or above the permissible exposure limits. This can include clean-up operations or operations involving hazardous substances at the workplace, and the storage, treatment, or disposal of hazardous substances, as well as emergency response operations. It complies with OSHA’s CFR 1910.120(e) standard.

What is the difference between 24-hour and 40-hour HAZWOPER training?

  • Besides the duration of the course, the 24-Hour offering is aimed primarily at individuals who work in an environment with limited opportunity for exposure to hazardous substances. This includes those who work with or near hazardous substances under permissible exposure limits. The 40-Hour HAZWOPER training is designed for individuals with risk for exposure to hazardous substances that exceed these limits and who must wear the appropriate personal protective equipment (PPE).

What kind of jobs typically require the 40-hour HAZWOPER certification?

  • Removing or handling of underground tanks and/or piping.
  • Handling contaminated soil and/or groundwater.
  • Conducting subsurface investigations.
  • Participating in construction work where hazardous substances may potentially be present.
  • Working at an uncontrolled hazardous waste site as listed by a federal or state regulatory agency.
  • Performing work at a listed or proposed-for listing on the Superfund National Priority List (NPL).
  • Performing work at a listed site or proposed for listing on a state priority list.
  • Conducting operations at corrective action sites covered by U.S. EPA's Resource Conservation and Recovery Act (RCRA).

How do you know if your workplace falls under the OSHA HAZWOPER standard?

  • Search for your company in the 27 OSHA Plan States, which are state-level regulatory agencies that implement and enforce HAZWOPER regulatory programs. State-level programs often exceed federal regulations.

What types of work are covered by HAZWOPER standards?

  • Uncontrolled hazardous waste cleanup regulated by the government
  • Corrective action cleanup at Resource Conservation and Recovery Act (RCRA) sites
  • Voluntary cleanup at uncontrolled hazardous waste sites
  • Operations conducted at treatment, storage, disposal (TSD) facilities
  • Emergency response operations with release or threat of release of hazardous substances

Does HAZWOPER certification expire?

  • Yes, HAZWOPER certifications do expire. They must be renewed annually with the 8-Hour HAZWOPER Refresher course.
