Question

When mechanical equipment is being used, the warning line shall erected not less than ________ feet from the roof edge which is parallel to the direction of mechanical equipment operation, and not less than _______ feet from the roof edge which is perpendicular to the direction of mechanical equipment operation?

Answer 1

The warning line should be placed 6 feet from the roof edge parallel to the mechanical equipment operation and 10 feet from the edge perpendicular to the equipment.

Step-by-step explanation:

When mechanical equipment is being used, the warning line shall be erected not less than 6 feet from the roof edge which is parallel to the direction of mechanical equipment operation, and not less than 10 feet from the roof edge which is perpendicular to the direction of mechanical equipment operation.

The distances are specified to ensure the safety of workers on the roof by providing a buffer zone between the working area and the roof edge.

These safety measures are to prevent falls and other accidents when mechanical equipment is operated in close proximity to the roof edge.

When using mechanical equipment on a rooftop, the warning line should be erected not less than X feet from the roof edge parallel to the direction of mechanical equipment operation, and not less than Y feet from the roof edge perpendicular to the direction of mechanical equipment operation.
