Safety glasses are required to be worn under which condition?

• A. Always
• B. Never
• C. Yes, if needed
• D. Only during inspections

Answer: (C)

Eye protection should be worn whenever there is a potential for eye injury, and the decision is based on the hazards of the task. If there’s a risk from flying particles, dust, chemical splashes, or bright/ radiant light, safety glasses are needed. The idea behind the option “Yes, if needed” is that you assess the task and put on protection only when the hazard exists, rather than insisting on constant wear or never wearing protection. In tasks with no exposure to eye hazards, protection isn’t required. The other choices don’t fit because wearing protection at all times isn’t always necessary and never wearing protection would be unsafe; protective eyewear isn’t only for inspections, as hazards can occur during normal work too.
