A "face protection shall be worn" sign is a safety sign used to indicate that protective face gear, such as a helmet, face shield, or goggles, must be worn in a specific area or during a specific task. This sign is typically used in industrial or construction settings where there is a risk of flying debris, sparks, or other hazards that could cause injury to the face or eyes. The sign may also be used in hazardous chemical or biological environments where additional face protection is required to prevent exposure to harmful substances. The sign usually includes a pictogram or symbol of a person wearing protective face gear, along with text indicating the requirement to wear face protection. The goal of the sign is to promote safety and reduce the risk of injury in hazardous work environments.
Mandatory signs recommend a particular conduct. This required sign stipulates that a protective apron must be worn.
