The five requirements
The employer designates a competent person as the safety monitor and makes sure the monitor:[1]
- Is competent to recognize fall hazards
- Warns an employee who appears unaware of a fall hazard or is acting unsafely
- Is on the same walking/working surface, within visual sighting distance of the employee
- Is close enough to talk to the employee
- Has no other responsibilities that could take attention away from monitoring
Where a safety monitor is allowed
Safety monitoring is not a general substitute for guardrails, nets or personal fall arrest. It appears in two places:
- Low-slope roofing. Roofers can be protected by a warning line combined with a safety monitoring system, and on roofs 50 feet or less in width a safety monitoring system alone is permitted.[2]
- A fall protection plan. Only for leading edge work, precast concrete erection or residential construction where conventional fall protection is infeasible or creates a greater hazard. The plan is written by a qualified person for that specific site and kept on site.[3]
Site rules that come with it
Where monitoring protects roofers on a low-slope roof, mechanical equipment may not be used or stored in that area. Only the roofers, or employees covered by a fall protection plan, may be in the monitored area. Employees working in a controlled access zone must comply promptly with the monitor's warnings.[1]
Safety monitor vs. safety observer
A safety monitor is a fall protection method in its own right, with legal duties attached and nothing else on their plate. A safety observer watches a wider set of activities and reports. An NSC Enterprises observer can record whether a required monitor is in place, on the same surface and undistracted, and escalate it if not. Who gets designated as the monitor is a decision for the employer of the workers, under its program. See how observers cover fall protection in high-risk work monitoring.
