When is the use of protective eyewear and face protection required?

The use of protective eyewear and face protection is required when there is a reasonable probability of being exposed to eye or face hazards. This encompasses various work environments where flying particles, hazardous liquids, or even harmful radiation may pose risks to the eyes and face. The emphasis on "reasonable probability" indicates that if there is any significant risk in the activity being performed, appropriate protective gear should be worn to ensure safety.

In contrast, the options suggesting protective gear is needed under lower-risk circumstances, such as during low risk of eye injury or only at night, do not account for the importance of preventive measures in all situations where hazards may be present. Lastly, while insulated tools may reduce certain types of electrical hazards, they do not specifically address the broader scope of eye and face hazards that can arise in various work tasks.
