What Does Control Line Mean?

A control line, within the context of workplace health and safety, refers to a restrictive marker used for designating areas along its perimeter that limits and/or prohibits access beyond a certain point.

Employers generally use control lines as a practical measure to identify hazardous locations reserved exclusively for trained personnel.

A control line is a boundary marker surrounding a designated area limiting and/or barring access to people based on circumstantial regulations. Control lines can include rope, wire, or tape running the dimensional perimeter of a bounded location to indicate a hazardous, or otherwise restricted, zone. Employers apply control lines at different sites to give a visual and physical reminder for unauthorized employees to avoid certain controlled areas.

The type of control line and placement of the control line may be subject to governmental regulations in some instances.
