As part of occupational health and safety regulations many industrial, commercial, office buildings, and more are required to post signs to keep workers, visitors, and customers safe. These signs work to inform and alert personnel and patrons of hazardous conditions and regulations. Self-adhesive or wall-mounted signs and posters range from disposal instructions at refuse stations to out of service signs at bathroom facilities. Freestanding options include everything from wet floor caution signs to tabletop no smoking signs.
