Not Sure If The 24 Hour HAZWOPER Is Right For You?

View our 24 Hour and 40 Hour HAZWOPER comparison table to see which course best fits your duties and expected exposure conditions. Employers are responsible for determining the appropriate training level for each worker.

The 24 Hour HAZWOPER course will not satisfy OSHA training requirements for workers who:

  • routinely wear respirators
  • engage in hazardous substance removal
  • enter IDLH atmospheres
  • perform large-scale remediation activities
  • may be exposed above OSHA permissible exposure limits

These workers typically require 40 Hour HAZWOPER training.

Course Description

Our Hazardous Waste Operations and Emergency Response (HAZWOPER) 24 Hour HAZWOPER Training was developed using Occupational Safety and Health Administration (OSHA) guidance documents in combination with extensive real-world field experience. This course is commonly referred to as OSHA 24, HAZWOPER 24, or the 24 Hour HAZWOPER.

In accordance with OSHA 29 CFR 1910.120(e), this training is required for individuals who plan to work on or around designated HAZWOPER sites. Upon successful completion, participants receive a certification that is widely recognized and accepted by regulatory authorities. The program is self-paced, giving students the flexibility to complete the course on their own schedule.

The curriculum incorporates self-assessment quizzes, interactive learning modules, and a final examination. Quizzes may be repeated as often as necessary to reinforce comprehension, while the final exam allows up to three attempts. Once completed successfully, an electronic certificate of completion is issued and delivered via email.

It is important to note that the 24 Hour HAZWOPER Training is delivered online. OSHA regulations require that employers also provide employees with site-specific, hands-on training on the actual personal protective equipment (PPE) and tools they will use on the job. This practical instruction must meet performance-based standards and may be conducted in a classroom or field setting.

Most individuals who require 24 hour HAZWOPER certification do not routinely wear PPE. However, in cases where PPE is necessary, employers are responsible for ensuring workers receive additional hands-on instruction with the exact equipment used in the field. This training is conducted in conjunction with the online 24 hour HAZWOPER course to ensure full compliance and workplace safety.

OSHA Regulatory Basis for 24-Hour HAZWOPER

The 24-Hour HAZWOPER training requirement originates from the Occupational Safety and Health Administration (OSHA) Hazardous Waste Operations and Emergency Response Standard found at 29 CFR 1910.120. This regulation was developed in response to the growing need for worker protection during hazardous waste cleanup operations, treatment, storage, disposal activities, and emergency response incidents involving hazardous substances. The standard was heavily influenced by the Superfund Amendments and Reauthorization Act (SARA) of 1986, which directed OSHA to establish comprehensive safety and health requirements for hazardous waste operations.

Under 29 CFR 1910.120(e)(3)(ii), OSHA requires 24 hours of initial instruction for workers classified as “Occasional Site Workers.” These individuals may occasionally enter hazardous waste sites or controlled work areas but are unlikely to be exposed to hazardous substances above permissible exposure limits (PELs). Typical workers falling under this category may include environmental technicians, groundwater monitoring personnel, inspectors, survey teams, or subcontractors performing limited task-specific duties at contaminated sites.

The OSHA 24-Hour HAZWOPER standard also applies to construction-related hazardous waste operations under 29 CFR 1926.65, which mirrors the general industry requirements contained in 29 CFR 1910.120. In addition, the Environmental Protection Agency (EPA) adopted OSHA’s HAZWOPER framework at 40 CFR Part 311 to protect state and local government employees engaged in hazardous waste operations in states without OSHA-approved State Plans.

Although the 24-Hour HAZWOPER course may be completed online for the knowledge-based portion of training, OSHA expects employers to provide additional site-specific instruction and supervised field experience appropriate to the worker’s assigned duties, hazards, personal protective equipment (PPE), decontamination procedures, emergency response protocols, and air monitoring equipment used at the jobsite. Workers covered under the 24-hour training category must also complete an annual 8-Hour HAZWOPER Refresher to maintain competency and regulatory compliance.

For workers who may be exposed above OSHA permissible exposure limits or who actively participate in hazardous substance removal or remediation operations, OSHA generally requires the more comprehensive 40-Hour HAZWOPER training under 29 CFR 1910.120(e)(3)(i).

  • Modern web browser

  • Audio/speakers or headphones for narrated content

What is the difference between the 24 hour HAZWOPER and 40 hour HAZWOPER courses?

The 24 hour HAZWOPER course is often available fully online and requires one day of hands-on instruction. However, employers must ensure that the worker is also trained on site-specific hazards. Here is a comparison of the 40 hour and 24 hour courses.

  • 24 Hour HAZWOPER: For qualifying occasional or limited-task workers; requires one day of supervised field experience and employer-provided site-specific instruction.

  • 40 Hour HAZWOPER: For general site workers with direct exposure; includes hands-on training and medical clearance

 

 

Bonus Tips for Employers:

  • Ensure the provider offers OSHA-compliant training with a certificate of completion.

  • Supplement online training with site-specific briefings or drills.

  • Maintain training records for compliance audits.

Site-Specific Training Clarification

OSHA expects employers to provide site-specific hands-on training using the actual PPE, air monitoring equipment, decontamination procedures, and emergency response equipment used at the worksite. OSHACode® offers a blended training option where we provide the online knowledge component while employers conduct required site-specific field training.
