Personal protective equipment (PPE) for the eyes and face is designed to prevent or lessen the severity of injuries to workers. OSHA says the employer must assess the workplace and determine if hazards that necessitate the use of eye and face protection are present or are likely to be present before assigning PPE to workers.
According to OSHA, a hazard assessment should determine the risk of exposure to eye and face hazards, including those which may be encountered in an emergency. Employers should be aware of the possibility of multiple and simultaneous hazard exposures and be prepared to protect against the highest level of each hazard.
