# Site-Specific Safety and Health Plan (HASP) Requirements Under 1910.120(b) HAZWOPER guide · 2 min read · Updated 2026-11-03 Every hazardous waste cleanup site needs a written **site-specific safety and health plan**, often called a HASP. It is part of the employer's safety and health program under 29 CFR 1910.120(b), must be kept on site, and must address the safety and health hazards of each phase of the operation. ## Required elements of the HASP Under 1910.120(b)(4)(ii), the plan must address at least: 1. A safety and health **risk or hazard analysis** for each site task and operation in the work plan 2. **Employee training** assignments 3. **Personal protective equipment** for each site task and operation ([PPE levels](https://www.hazwoperosha.com/guides/ppe-levels-a-b-c-d/)) 4. **Medical surveillance** requirements ([medical surveillance](https://www.hazwoperosha.com/guides/hazwoper-medical-surveillance/)) 5. Frequency and types of **air monitoring**, personnel monitoring and environmental sampling, including instrument maintenance and calibration ([air monitoring](https://www.hazwoperosha.com/guides/air-monitoring/)) 6. **Site control** measures ([work zones](https://www.hazwoperosha.com/guides/site-control-work-zones/)) 7. **Decontamination** procedures ([decon](https://www.hazwoperosha.com/guides/hazwoper-decontamination/)) 8. An **emergency response plan** meeting 1910.120(l) 9. **Confined space entry** procedures 10. A **spill containment** program ## The wider safety and health program The HASP sits inside a written program that also includes: - An **organizational structure** naming the general supervisor, the site safety and health supervisor, and lines of authority - A **comprehensive work plan** covering tasks, objectives, staffing, equipment and training - Standard operating procedures and the medical surveillance program ## Pre-entry briefings and inspections The plan must provide for **pre-entry briefings** before site activities start, and at other times as needed, so employees know the plan and are following it. The employer must also inspect the site to judge whether the plan is working and fix any problems found. ## Who writes the HASP A qualified person, usually a certified industrial hygienist, safety professional or experienced site safety officer, writes the HASP using the site characterization data. Contractors and subcontractors must be told about the site's hazards. The plan is a living document: update it when conditions, tasks or data change. ## Frequently asked questions ### What does HASP stand for? HASP stands for Health and Safety Plan. Under HAZWOPER it is the site-specific safety and health plan required by 29 CFR 1910.120(b)(4). ### Does the HASP have to be kept on site? Yes. The site safety and health plan must be kept on site and be available to employees, contractors and OSHA. ### How often must the HASP be updated?
