Which of the following is an unsafe condition?

• A. Poor illumination
• B. Failing to follow procedures
• C. Engaging in horseplay
• D. Servicing a machine while energized

Answer: (A)

An unsafe condition is a physical or environmental factor in the workplace that increases the chance of an incident if not corrected. Poor illumination fits this because inadequate lighting makes hazards harder to see, which can lead to trips, mistakes, or mishandling tools and equipment. It’s about the condition of the environment itself, not a person’s behavior.

The other options involve actions rather than environmental factors: failing to follow procedures is a lapse in behavior or compliance; horseplay is unsafe behavior; servicing a machine while energized is a risky procedure or energy-control violation. These are unsafe acts or procedural hazards, whereas poor illumination is a conditions-based hazard that directly creates risk in the work area.
