Identify two chemical hazards in the OR and one safety measure for each.

• A. Ionizing radiation requiring shielding
• B. Laser hazards requiring eyewear
• C. Sterilants/disinfectants with ventilation and PPE; Anesthetic solvents with scavenging and proper storage
• D. Noise hazards requiring ear protection

Answer: (C)

In the operating room, two chemical hazards are sterilants/disinfectants and volatile anesthetic solvents, and each has its own protective approach. Sterilants and disinfectants emit vapors that can irritate the respiratory tract, eyes, and skin; to minimize exposure, ensure good ventilation to dilute and remove vapors and use appropriate PPE such as gloves, eye protection, and a gown. Volatile anesthetic solvents (waste anesthetic gases) pose inhalation risks to staff; the safety measure is a scavenging system that captures and removes these gases, along with proper storage and handling to prevent leaks or spills and ensure labeled, sealed containers.

Other options describe nonchemical hazards found in the OR—physical hazards like ionizing radiation that require shielding, laser hazards that require eyewear, and noise hazards that require ear protection—so they do not address chemical risks.
