If a worker has a visual impairment in one eye, when is protective eyewear required?

Protective eyewear is required for a worker with a visual impairment in one eye in all specified situations, making the option that includes each scenario the correct choice. This is essential for ensuring safety and protection, as individuals with a visual impairment in one eye may have reduced depth perception and field of vision, increasing the risk of accidents or injuries.

In contexts like mess cooking duties, where sharp tools and hot surfaces are present, protective eyewear helps prevent accidents that could lead to further injury. During combat duties, the environment is inherently dangerous and requires the utmost caution; protective eyewear can safeguard against debris and other hazards. Finally, when standing a military watch, the need for clear vision to respond to potential threats or emergencies is crucial, so wearing protective eyewear serves to enhance safety and duty performance.

Each situation presents its own risks, and protective eyewear is a key component in maintaining the safety and well-being of the individual and those around them.
