Which option is NOT a physical hazard that threatens safety?

• A. Poison
• B. Fire
• C. Disasters
• D. Hand hygiene

Answer: (D)

Distinguishing physical hazards from safety practices that prevent harm. A physical hazard is something in the environment that can cause physical injury or harm. Poison fits this category because exposure can injure or kill through ingestion, inhalation, or skin absorption. Fire is a clear physical hazard due to heat and flames that can cause burns and smoke inhalation, and disasters create dangerous conditions like structural failure or hazardous environments. Hand hygiene, on the other hand, is a preventive practice in infection control aimed at reducing the transmission of pathogens. It is not a hazard itself; it lowers risk rather than posing a threat to safety. So hand hygiene is not a physical hazard, making it the correct choice.
