What type of control is using workplace signage and rules classified as?

Using workplace signage and rules is classified as administrative controls. Administrative controls are procedures and policies implemented to alter the way people work or to communicate safety information effectively. Signage serves as a means to inform employees of hazards, provide instructions, and establish protocols for maintaining safety. By clearly communicating expectations and guidelines, administrative controls help to reduce the likelihood of accidents and injuries.

This classification differs from engineering controls, which involve physical modifications to the work environment to reduce hazards, personal protective equipment, which involves the use of gear to protect individuals from hazards while they work, and elimination, which refers to completely removing a hazard from the workplace. Each has its place in a comprehensive safety program, but signage and rules primarily aim at guiding behavior and enhancing awareness, thus fitting squarely within the realm of administrative controls.
