Covers

Covers are fastened over holes in the working surface to prevent falls.

• Covers located in roadways and vehicular aisles must be capable of supporting, without failure, at least twice the maximum axle load of the largest vehicle expected to cross over the cover.
• All other covers must be capable of supporting, without failure, at least twice the weight of workers, equipment, and materials that may be imposed.
• All covers must be secured when installed to prevent accidental displacement by wind, equipment, or workers. A cover is not secured if it can be picked up with moderate effort.
• All covers should be marked in paint with the words “CAUTION - HOLE - DO NOT REMOVE”.
