Which of the following is a physical hazard in the surgical environment?

• A. Physical hazard
• B. Biological hazard
• C. Chemical hazard
• D. Ergonomic hazard

Answer: (A)

Physical hazards are the risks in the surgical environment that cause injury from energy or mechanical forces—things like sharps injuries, electrical hazards from powered equipment, radiation from imaging, heat or cold exposure, burns, noise, and slips or falls. These hazards arise from the way energy is transferred to the body or from hazards in the physical environment, rather than from pathogens, chemicals, or motions.

Among the options, the choice that identifies a physical hazard is the one that explicitly labels the hazard category as physical. Biological hazards involve pathogens and infections, chemical hazards involve sterilants and solvents, and ergonomic hazards involve posture and repetitive motion issues. Understanding these distinctions helps you apply appropriate controls: using sharps precautions and PPE for physical hazards, proper shielding and equipment safety for radiation, safe handling for electrical risks, and general housekeeping to prevent slips.
