What type of control does a barricade represent?

A barricade is classified as an engineering control because it is a physical means of preventing access to hazardous areas or situations. Engineering controls are designed to eliminate or reduce exposure to hazards through the use of physical barriers, redesigning workspaces, or modifying equipment. In the case of a barricade, it directly creates a barrier that protects workers from potential dangers, such as electrical hazards or moving machinery.

This type of control is effective because it does not rely on human behavior or compliance to function, meaning that as long as the barricade is properly erected and maintained, it will provide ongoing protection. By physically isolating workers from danger, engineering controls like barricades are a fundamental aspect of workplace safety strategies.
