Warning line review

The warning line shall be erected around all sides of the roof work area.

Points of access, materials handling areas, storage areas, and hoisting areas shall be connected to the work area by an access path formed by two warning lines. <br>

(i) When mechanical equipment is not being used, the warning line shall be erected not less than 6 feet (1.8 m) from the roof edge. <br>

When the path to a point of access is not in use, a rope, wire, chain, or other barricade, equivalent in strength and height to the warning line, shall be placed <br>across the path at the point where the path intersects the warning line erected around the work area, or the path shall be offset such that a person cannot walk directly into the work area.

Warning lines shall consist of ropes, wires, or chains, and supporting stanchions

The rope, wire, or chain shall be flagged at not more than 6-foot (1.8 m) intervals with high-visibility material;

The rope, wire, or chain shall be rigged and supported in such a way that its lowest point (including sag) is no less than 34 inches (.9 m) from the walking/ <br>working surface and its highest point is no more than 39 inches (1.0 m) from the walking/working surface;

After being erected, with the rope, wire, or chain attached, stanchions shall be capable of resisting, without tipping over, a force of at least 16 pounds (71 N) <br>applied horizontally against the stanchion, 30 inches (.8 m) above the walking/ working surface, perpendicular to the warning line, and in the direction of the floor, roof, or platform edge;

The line shall be attached at each stanchion in such a way that pulling on one section of the line between stanchions will not result in slack being taken up in adjacent sections before the stanchion tips over.

No employee shall be allowed in the area between a roof edge and a warning line unless the employee is performing roofing work in that area. <br>

The employer shall designate a competent person to monitor the safety of other employees and the employer shall ensure that the safety monitor complies with the following requirements:

(a) The safety monitor shall be competent to recognize fall hazards; <br>(b) The safety monitor shall warn the employee when it appears that the employee is unaware of a fall hazard or is acting in an unsafe manner; <br>(c) The safety monitor shall be on the same walking/working surface and within visual sighting distance of the employee being monitored; <br>(d) The safety monitor shall be close enough to communicate orally with the employee; and have no other duties

No employee, other than an employee engaged in roofing work shall be allowed in an area where an employee is being protected by a safety monitoring system. <br>
