MSHA's Accident Prevention Program
Skylight Screen Guard
Since 1983, 21 miners have been injured from falls through unguarded skylights. One fatality was reported. To prevent falls through acrylic dome and corrugated fiberglass skylights, manufacturers have developed screen safety guards.
Properly installed skylight screen guards can completely eliminate the hazard of falling through a skylight.
Regular corrugated fiberglass skylights and trapezoidal standing seam skylights are especially hazardous since they are at the same level as the roofing and have the same profile. Dirt and debris can camouflage skylights. Skylights are easily overlooked when personnel are accessing, working or walking on the roof. Screen guarding can be specifically designed to prevent falls through many types of skylights.
Note: Mounting hardware should be corrosion resistant and designed specifically for each skylight system. For more information about preventing falls of workers through skylights: http://www.cdc.gov/niosh/docs/2004-156/.
