Questions & Answers

Is the temporary cover listed and labeled to meet OSHA requirements as a "Hole" cover during construction?

Asked by: Kristopher
Hello and thank you for your inquiry. We do not have any test data to support a load rating for the temporary cover for our floor boxes or poke through devices. UL only requires the UL 514A cover load test to be applied to the actual finished covers. The OSHA fall protection standard is found in 29 CFR §1926.500(b) and has the following definitions and requirements. The requirement highlighted below would be similar to the 300 lb. load required for the finished cover in UL 514A. As we have not tested the temporary cover, they would need to protect the opening using another approved method in 29 CFR §1926.500. Hole means a gap or void 2 inches (5.1 cm) or more in its least dimension, in a floor, roof, or other walking/working surface. (4) Holes. (i) Each employee on walking/working surfaces shall be protected from falling through holes (including skylights) more than 6 feet (1.8 m) above lower levels, by personal fall arrest systems, covers, or guardrail systems erected around such holes. (ii) Each employee on a walking/working surface shall be protected from tripping in or stepping into or through holes (including skylights) by covers. (iii) Each employee on a walking/working surface shall be protected from objects falling through holes (including skylights) by covers. (i) Covers. Covers for holes in floors, roofs, and other walking/working surfaces shall meet the following requirements: (1) Covers located in roadways and vehicular aisles shall be capable of supporting, without failure, at least twice the maximum axle load of the largest vehicle expected to cross over the cover. (2) All other covers shall be capable of supporting, without failure, at least twice the weight of employees, equipment, and materials that may be imposed on the cover at any one time. (3) All covers shall be secured when installed so as to prevent accidental displacement by the wind, equipment, or employees. (4) All covers shall be color coded or they shall be marked with the word “HOLE” or “COVER” to provide warning of the hazard. Note: This provision does not apply to cast iron manhole covers or steel grates used on streets or roadways.
