OSHA’s HAZWOPER Training Requirements for Employers

1. Provide the Correct Level of Training for Employees

The HAZWOPER training requirements state that employers must ensure that workers receive the appropriate level of HAZWOPER training based on their job duties and exposure risks.

✔ 40 Hour HAZWOPER Training

✅ Required for workers who are regularly exposed to hazardous substances and involved in cleanup operations.
✅ Includes 40 hours of instruction, hands-on training of SITE SPECIFIC Personal Protective Equipment (PPE) + 3 days of supervised field experience.
✅ Workers must be medically cleared before starting work.

✔ 24 Hour HAZWOPER Training

✅ For workers who visit hazardous sites occasionally but have limited exposure.
✅ Includes 24 hours of training + 1 day of field experience.

✔ 8 Hour HAZWOPER Refresher Training

✅ Required annually for employees with 24-hour or 40-hour certification.
✅ Covers updates on safety practices, hazard recognition, and emergency response.

✔ 8 Hour HAZWOPER Supervisor Training

✅ Required for managers and supervisors overseeing hazardous operations.
✅ Must be completed in addition to 24-hour or 40-hour training.

2. Conduct Job Hazard Assessments (JHA)

Employers must conduct hazard assessments to determine:

• The types of hazardous substances workers may be exposed to.
• The potential risks of exposure, spills, or environmental contamination.
• The appropriate level of PPE required for workers.

3. Implement a Health and Safety Plan (HASP)

Before any hazardous operations begin, employers must develop a Health and Safety Plan (HASP) that includes:

• Hazard identification and risk assessment.
• Emergency response protocols for hazardous material spills.
• Medical surveillance programs for worker health monitoring.
• Decontamination procedures to prevent toxic substance spread.
• Recordkeeping of training, incidents, and PPE usage.

4. Provide Personal Protective Equipment (PPE)

Employers must provide workers with proper PPE based on the risk level. OSHA classifies PPE levels as:

• Level A – Fully encapsulated suits with a Self Contained Breathing Apparatus (SCBA) for maximum protection.
• Level B – Chemical-resistant suits with SCBA, used when airborne hazards exist.
• Level C – Chemical-resistant clothing with air-purifying respirators.
• Level D – Basic work uniforms with minimal protection.

Employers must train workers on PPE use, limitations, and maintenance.

5. Conduct Medical Surveillance for Workers

Workers who are regularly exposed to hazardous substances must undergo medical monitoring to track their health. Employers must provide:

• Pre-employment medical evaluations.
• Ongoing health assessments for early detection of toxic exposure effects.
• Exit medical exams for workers leaving hazardous environments.

6. Establish Emergency Response Plans

Employers must create Emergency Response Plans (ERPs) to ensure safe operations during hazardous incidents. Plans should cover:

• Evacuation procedures in case of a chemical spill or explosion.
• First-aid and medical response protocols for exposure injuries.
• Coordination with local emergency responders (fire, Hazardous Materials (HAZMAT) teams.

7. Maintain Training Records and Certifications

Employers are required to document all employee training and certifications. Training records must include:

• Employee name and job role.
• Type of training completed (40-hour, 24-hour, refresher, etc.).
• Date of training completion and instructor information.
• Proof of competency tests and field training evaluations.

OSHA inspectors may request these records during compliance audits.

8. Spill Response and Clean Up

Spill response and cleanup operations are conducted under strict procedures designed to protect workers, the environment, and surrounding communities from hazardous releases. When a spill occurs—whether it involves a leaking drum, ruptured pipeline, or chemical overfill—the response begins with immediate site control and hazard assessment. Trained personnel must identify the substance using available data such as labels, Safety Data Sheets (SDS), or field monitoring instruments. Based on this evaluation, the appropriate level of PPE and cleanup teams are assigned in accordance with the site’s Health and Safety Plan (HASP).

Containment is the first operational priority. Workers use absorbent booms, neutralizing agents, dikes, or trenches to prevent further spread or migration of the material. Once stabilized, cleanup and decontamination begin—typically involving the safe collection of contaminated soil, liquids, or debris for proper disposal under EPA and RCRA regulations. Throughout the process, continuous air monitoring ensures that exposure levels remain below OSHA’s permissible exposure limits (PELs).

9. Decontamination Procedures

At a HAZWOPER site, decontamination procedures are a critical component of worker protection and environmental safety, ensuring that hazardous substances are not spread beyond controlled areas. Under OSHA 29 CFR 1910.120(k), every site must establish and implement a decontamination plan before any personnel or equipment enter the exclusion (Hot) zone. The process begins with the design of a decontamination line, which provides a structured, step-by-step sequence for removing contaminants as workers transition from the contaminated area to clean zones. Decontamination typically involves gross contamination removal, washing and rinsing, and removal of PPE in a controlled order to prevent cross-contamination. Specialized solutions or neutralizing agents may be used depending on the type of chemical or biological hazard present. All disposable PPE and cleaning materials are treated as hazardous waste and managed according to EPA and RCRA regulations. Continuous air monitoring and supervision ensure that procedures remain effective and that no personnel bypass required steps. Proper decontamination not only protects individual workers but also prevents secondary exposure, maintains the integrity of the worksite, and fulfills regulatory requirements for safe hazardous waste operations.

10. Confined Space Entry

Confined space entry presents some of the most serious hazards workers can face, combining the dangers of limited oxygen, toxic atmospheres, and restricted movement. Under OSHA 29 CFR 1910.146 and 29 CFR 1910.120, a confined space is defined as an area large enough for a worker to enter and perform assigned tasks, but with limited means of entry or exit and not designed for continuous occupancy. Examples include storage tanks, pits, vaults, silos, and sewers commonly encountered during hazardous waste cleanup or remediation work. Before any entry occurs, the employer must develop a Confined Space Entry Program that includes atmospheric testing for oxygen content, flammable gases, and toxic vapors; implementation of ventilation or purging procedures; and assignment of a trained attendant to monitor entrants at all times. Workers entering the space must wear appropriate PPE—such as respirators or supplied-air systems—based on the results of air monitoring. A permit system must be used for permit-required confined spaces, and rescue procedures must be established and rehearsed before entry. Proper planning, monitoring, and communication are essential to prevent asphyxiation, chemical exposure, or entrapment incidents, ensuring all confined space operations are performed safely and in compliance with HAZWOPER and OSHA standards.

11. Drums and Containers

The safe handling of drums and containers is essential to prevent leaks, fires, explosions, and worker exposure to hazardous substances. Under OSHA 29 CFR 1910.120(j), all containers must be visually inspected, identified, and evaluated before being moved or opened. Workers should look for signs of corrosion, bulging, leakage, or incompatible labeling, and treat all unidentified drums as potentially hazardous until properly characterized. Specialized drum handling equipment—such as overpack drums, drum grapplers, and remotely operated opening devices—must be used to minimize manual contact and prevent tipping or rupture. Opening operations should only be performed by trained personnel wearing the appropriate level of PPE (A, B, or C), depending on the potential hazards present. Continuous air monitoring should be conducted when venting or sampling drums to detect flammable vapors or toxic gases. All removed materials and residues must be managed in accordance with EPA’s RCRA hazardous waste regulations, and incompatible substances must be segregated to avoid chemical reactions. Proper drum and container handling not only ensures regulatory compliance but also safeguards the health of workers and the integrity of the site cleanup operation.
