#239 Guardrails

A fall from an elevation can seriously injure or kill a worker. Employers should implement a fall prevention safety program by identifying potential fall hazards throughout the workplace, training employees, providing fall protection equipment, and placing guardrails around elevated locations. Guardrails protect workers from falls and act as a barrier to prevent tools and equipment from falling on workers below.

Cal/OSHA requires guardrails to be installed at the open sides of all work surfaces that are 7 ½ ft. or higher, or workers must be protected by other fall protection or, if justified, by a valid fall protection plan…1621(a).
