HAZWOPER Refresher Training

The 8-Hour HAZWOPER Refresher is annual training for workers and supervisors who previously completed 24-hour or 40-hour HAZWOPER initial training and continue to perform covered hazardous-waste operations. Under 29 CFR 1910.120(e)(8), refresher training must be completed annually and should reinforce the hazards, controls, procedures, and lessons relevant to the employee’s work.

Who Needs Which Refresher?

Worker or Role Typical Refresher Requirement What the Refresher Should Reinforce Key OSHA Reference

Keep Your HAZWOPER Training Current

Training Milestone What to Do Employer Responsibility
Initial 24- or 40-Hour Training Complete the initial course required for the employee’s assigned duties and anticipated exposure. Provide hands-on instruction, supervised field experience when applicable, site-specific training, and competency verification.
Before the 12-Month Anniversary Complete the annual 8-hour refresher before training currency lapses. Track due dates, schedule refresher training, and address changed hazards, procedures, and work assignments.
If Training Has Lapsed Complete refresher training promptly and do not assume the prior certificate alone authorizes covered work. Evaluate the lapse, employee experience, retained knowledge, current duties, and whether additional or repeat initial training is necessary.

Refresher Training Requirement

According to OSHA 29 CFR 1910.120(e)(8), employees who have previously completed the 24- or 40-hour HAZWOPER training for general site workers must complete at least eight (8) hours of refresher training every year. The purpose of this refresher is to keep knowledge current on workplace hazards, changes in regulations, site-specific procedures, and safe work practices. Failure to complete refresher training can result in expired certification, which may prevent employees from entering hazardous waste sites or participating in cleanup operations.

The refresher also helps employers stay compliant with the Occupational Safety and Health Administration (OSHA) and Environmental Protection Agency (EPA) standards by verifying that employees remain capable of safely performing their duties in potentially hazardous environments.

Course Topics

The HAZWOPER 8-hour refresher reinforces the fundamental concepts of hazardous waste operations and updates employees on any regulatory or site-specific changes. Typical topics include:

  • Recognition and evaluation of hazardous substances

  • Health effects, toxicology, and exposure routes

  • Use, care, and limitations of Personal Protective Equipment (PPE)

  • Air monitoring and instrumentation

  • Decontamination procedures and zone control

  • Emergency response and spill containment

  • Medical surveillance and incident reporting

  • Review of new or updated OSHA/EPA requirements

Frequently Asked Questions

Who needs an 8-Hour HAZWOPER Refresher?

Workers and supervisors who previously completed initial 24-hour or 40-hour HAZWOPER training and continue to perform covered hazardous-waste operations generally need annual refresher training. This includes many remediation workers, environmental consultants, sampling personnel, hazardous-waste site workers, and on-site supervisors.

How often is HAZWOPER refresher training required?

For workers covered by 29 CFR 1910.120(e), refresher training is required annually. The refresher is generally completed within 12 months of the employee’s prior initial training or most recent refresher training.

Is the HAZWOPER refresher always eight hours?

For 24-hour and 40-hour HAZWOPER site workers and supervisors, the annual refresher requirement is eight hours. Emergency responders under 29 CFR 1910.120(q) have a different requirement: annual refresher training must be sufficient in content and duration to maintain competency for the responder’s assigned role, or the employee must demonstrate competency at least yearly.

Do 24-Hour HAZWOPER workers need the same refresher as 40-Hour workers?

Yes. Workers who completed either initial 24-hour or 40-hour HAZWOPER training generally complete an 8-hour annual refresher to maintain training currency. The employer should ensure the refresher remains relevant to the employee’s assigned duties, hazards, and work environment.

Do HAZWOPER supervisors need annual refresher training?

Yes. On-site managers and supervisors who completed HAZWOPER training must maintain their training currency through annual refresher training. Their refresher should reinforce supervisory responsibilities, site safety and health program implementation, PPE, air monitoring, emergency procedures, and worker protection.

Can I take an 8-Hour HAZWOPER Refresher online?

Yes. Online training can provide the knowledge-based portion of an 8-hour HAZWOPER refresher. Employers must still provide site-specific updates, practical instruction, PPE and equipment training, and competency verification appropriate to the employee’s actual worksite and assigned duties.

Does the 8-Hour HAZWOPER Refresher replace site-specific training?

No. The refresher course reinforces HAZWOPER knowledge, but it does not replace employer-provided site-specific training. Employers must train workers on current site hazards, the Health and Safety Plan, PPE, monitoring procedures, work zones, decontamination procedures, emergency contacts, and task-specific controls.

What topics should an 8-Hour HAZWOPER Refresher cover?

A refresher should reinforce the hazards, controls, procedures, and lessons relevant to the employee’s work. Common topics include hazard recognition, toxicology, PPE, respiratory protection, air monitoring, decontamination, site control, emergency procedures, medical surveillance, regulatory updates, and lessons learned from incidents or near misses.

What happens if my HAZWOPER refresher is expired?

If refresher training lapses, the employee should complete refresher training as soon as possible. The employer should evaluate the length of the lapse, the employee’s work history, retained knowledge, changes in site hazards or procedures, and whether additional training or repeat initial training is needed before the employee returns to covered work.

Do I have to repeat the full 24-hour or 40-hour course if my refresher is late?

Not necessarily. OSHA does not establish one automatic rule requiring every worker with a late refresher to repeat the full initial course. The employer must evaluate the situation and determine whether the employee needs only refresher training or additional instruction based on the length of the lapse, work history, knowledge, and current job duties.

Does the HAZWOPER refresher apply to emergency responders?

Emergency responders have separate annual competency requirements under 29 CFR 1910.120(q). Their refresher training must be sufficient to maintain the competencies required for their assigned role, such as Awareness, Operations, Technician, Specialist, or Incident Commander. An 8-hour site-worker refresher may not meet the needs of every emergency-response role.

What records should employers keep for HAZWOPER refresher training?

Employers should maintain records showing the employee’s name, course completion date, training provider, course title, certificate or completion documentation, and any site-specific or practical training completed. Records should also document competency verification and additional training provided when duties or site conditions change.
