Which item is listed as an unsafe condition?

• A. Poor illumination
• B. Failing to follow instructions
• C. Engaging in horseplay
• D. Servicing equipment in motion

Answer: (A)

Unsafe conditions are physical hazards in the environment that can increase the risk of an incident. Poor illumination fits this category because insufficient lighting is a environmental factor that reduces visibility, making it easier to miss hazards, misread controls, or trip and fall.

The other options describe unsafe acts—how people behave rather than the surroundings. Failing to follow instructions is a deviation from procedures; engaging in horseplay is reckless behavior; servicing equipment in motion involves performing maintenance while machinery is active, which is unsafe because it exposes you to moving parts. Therefore, poor illumination is the unsafe condition listed.
