Operating Room Environmental Safety: Addressing Potential Hazards

OR environmental hazard controls ensure patient/staff safety:

1. Ventilation: Positive pressure; ≥20 ACH; prevents contaminated air ingress.
2. HEPA Filtration: Removes airborne particles, bacteria, viruses.
3. Temperature/Humidity Control: 68–75°F (20–24°C), 30–60% RH; prevents hypothermia, condensation.
4. Cleaning/Disinfection: Terminal cleaning between cases; EPA-registered disinfectants; high-touch focus.
5. Waste Management: Segregated streams (sharps, red bag, chemo, RCRA); point-of-use containers.
6. PPE & Smoke Evacuation: Surgical masks, gowns, gloves; smoke evacuators for electrosurgery/laser plume.
7. Emergency Preparedness: Fire (OR-specific), spill, power failure protocols; drills.
8. Staff Training: AORN guidelines, hazardous material handling, emergency response.
9. Standards Compliance: AORN, CMS, Joint Commission, NFPA 99.
10. Continuous Monitoring: Particle counts, pressure differentials, temperature, humidity.

Multilayered controls maintain asepsis and safety.
