In a construction environment, the standards of OSHA need to be followed with an aim to avoid any accident, and in this case, demarcation barrier warning lines are workable. For more information, you can refer to 29 CFR 1926.502(f). And it is necessary to make sure everyone’s safety.
In case you are unsure regarding demarcation barrier warning lines: this is fundamentally a system intended to alert individuals that are moving toward an unprotected side or corner, and which assigns a zone where roofing work could begin without the utilization of body belt, guardrail, or safety net structures to make sure the safety of individuals in the region.
The system of warning lines and their utilization need to fulfill the following requirements:
- The system should be established throughout the sides of the rooftop work zone.
- At the time mechanical gear is not in use, the demarcation barrier warning lines need to be established at least 6 feet from the rooftop edge.
- At the time mechanical gear is in use, these lines need to be established at least 6 feet from the rooftop edge which is equivalent to the route of mechanical gear functional, and at the very least 10 feet from the rooftop edge which is perpendicular to the route of mechanical gear procedure.
- The workplace area needs to be linked to access points, materials dealing zones, storage zones, and hoisting zones with the way of access path created by two warning lines.
- At the time the route to the point of access is not functional, in this case, wire, rope, chain, or other barrier, having comparable strength and tallness to the warning line, will be required to set up where the route crosses the warning line created around the work zone. On the other hand, the route needs to be offset such that an individual cannot walk straight to the work zone.
- Demarcation barrier warning lines will have ropes, wires, chains, and supporting foundations established as follows:
- In this case, the wire, rope, or chain required to be flagged under 6-foot intervals with high visibility material.
- The framework needs to be fixed and supported in a manner its absolute bottom (including sag) is no under 34 inches from the walking surface, and its top point is under 39 inches from the walking surface.
- In such cases, foundations need to be fit for withstanding, without collapsing, a strength of a minimum of 16 pounds connected horizontally against the stanchion, 30 inches over the walking surface, perpendicular to the warning line.
- In this case, the rope, wire, or chain need to have at least 500 pounds of strength.
- The line needs to be connected at every foundation so that dragging on one part of the line between foundations won’t cause slack being taken up in adjoining areas before the foundation topple.
