Environmental Safety and Occupational Health
This domain tests worker protection in decontamination and sterile processing: bloodborne pathogens, chemical safety, respiratory protection, sharps, spills, ergonomics, and environmental controls. Items often present an exposure or hazard and ask for the correct immediate action and program element.
Core rules
- OSHA Bloodborne Pathogens standard (29 CFR 1910.1030) requires a written exposure control plan reviewed at least annually, hepatitis B vaccination offered within 10 working days of assignment, PPE, labeled containers, and post-exposure evaluation.
- Hazard Communication (29 CFR 1910.1200) requires accessible Safety Data Sheets and training for every hazardous chemical, including sterilants, high-level disinfectants, and cleaning agents.
- Respiratory protection (29 CFR 1910.134) requires medical evaluation, annual fit testing, and training before N95 use.
- Engineering and work-practice controls come first: ventilation and local exhaust, closed containers, leak-proof transport, no recapping by hand, and eyewash stations where corrosives are used.
- Chemical spills are handled with the SDS, spill kit, PPE, and ventilation; never return a spilled sterilant to its container.
- Report every exposure and near miss, and document the evaluation.
Worked example
A technician splashes high-level disinfectant into one eye. Reasoning: go immediately to the eyewash and irrigate for at least 15 minutes, remove contact lenses if present, then seek medical evaluation, report the exposure, and review the SDS and the task's engineering controls. Delay or incomplete irrigation worsens injury and complicates the claim.
Traps that cost marks
Treating PPE as the only control; keeping SDSs locked away; skipping fit testing because a respirator was issued; using a spill kit without reading the SDS; forgetting that latex allergy and ergonomic injury are also occupational health issues.
