29 CFR 1910.120: OSHA HAZWOPER Standard

Regulatory citation: 29 CFR 1910.120, Hazardous Waste Operations and Emergency Response

What Is HAZWOPER?

OSHA's Hazardous Waste Operations and Emergency Response standard (HAZWOPER) protects workers in five groups of operations: cleanups required by a government body at uncontrolled hazardous waste sites, corrective actions under RCRA, voluntary cleanups at sites recognized by a government body as uncontrolled hazardous waste sites, operations at RCRA treatment, storage and disposal (TSD) facilities, and emergency response to releases of hazardous substances, wherever they occur.

Why HAZWOPER Matters

Cleanup sites and chemical releases can expose workers to toxic, flammable and reactive substances, often before the hazards are fully known.

Core Requirements

1. Written Safety and Health Program

Employers at cleanup sites need a written program covering organizational structure, a workplan, a site-specific safety and health plan, training, medical surveillance and standard operating procedures.

2. Site-Specific Safety and Health Plan

Each site plan must include a hazard analysis for each task, training assignments, PPE, air monitoring, site control, decontamination, emergency response and spill containment, among other elements.

3. Initial Training

General site workers need at least 40 hours of off-site instruction plus three days of supervised field experience. Occasional workers with limited tasks, and workers in fully characterized areas below exposure limits without respirators, need at least 24 hours plus one day. On-site managers and supervisors also need at least eight hours of specialized training.

4. Annual Refresher

Employees, managers and supervisors covered by the cleanup training requirements must receive eight hours of refresher training each year.

5. Medical Surveillance

Medical surveillance covers employees exposed at or above permissible exposure limits for 30 days or more a year, employees who wear respirators 30 days or more a year, employees with symptoms of overexposure, and HAZMAT team members. Exams are due before assignment, at least every 12 months (up to two years if the physician decides), and at termination unless the employee had an exam in the prior six months.

6. Emergency Response

Employers whose employees respond to releases need a written emergency response plan and an incident command system. Training ranges from awareness level to operations (at least 8 hours), technician, specialist and on-scene incident commander (at least 24 hours each), with annual refreshers or yearly competency demonstrations.

Common Compliance Approaches

Define Your Scope First

Confirm which of the five operation types applies before building a program.

Keep a Training Matrix

Track each worker's training level and refresher due date.

Schedule Medical Exams Proactively

Track exam due dates for every covered worker.

Example: HAZWOPER in Practice

An environmental contractor is hired to clean up a state-listed former plating site. It writes a site safety and health plan with a hazard analysis for drum removal, sets up decontamination zones and plans air monitoring. Workers have 40-hour training and current refreshers, and those wearing respirators are in medical surveillance.

Frequently Asked Questions

Does every HAZWOPER worker need 40-hour training?

No. General site workers need 40 hours plus three days of field experience, but occasional workers and some low-exposure workers need 24 hours plus one day. Emergency responders follow separate training levels.

How often is HAZWOPER refresher training required?

Workers covered by the cleanup site training rules need eight hours of refresher training every year. Emergency responders need annual refresher training or must demonstrate competency at least once a year.

Does HAZWOPER apply if my employees just evacuate during a spill?

If employees evacuate and none are allowed to help handle the emergency, the employer is exempt from the emergency response plan requirements as long as it has an emergency action plan meeting 29 CFR 1910.38.
