The 40-Hour HAZWOPER course is the initial off-site instruction described in OSHA's Hazardous Waste Operations and Emergency Response standard, 29 CFR 1910.120. Under paragraph (e)(3)(i), general site workers - equipment operators, general laborers, and supervisory personnel engaged in hazardous substance removal or other activities that expose or potentially expose them to hazardous substances and health hazards - must receive a minimum of 40 hours of instruction off the site, plus a minimum of three days of actual field experience under the direct supervision of a trained, experienced supervisor. The HAZWOPER 40-Hour study guide has 6 sections and about 1,966 words.
01Site Safety and Health Program Elements and Organizational Structure
A hazardous waste site safety and health program is built on a written plan that assigns responsibility and defines how work is controlled. Know the core elements: a defined organizational structure with clear lines of authority; a site-specific safety and health plan; hazard identification and site characterization; training; medical surveillance; PPE and air monitoring programs; site control (zones and communication); decontamination; emergency response; and recordkeeping.

Site characterization answers three questions: what contaminants are present, where they are, and how they can hurt workers. The sequence is off-site information review (records, historical use, prior reports), then on-site survey (walkover, interviews, visual evidence), then sampling and monitoring to confirm.
