Fall-through protection from a tested skylight

Summary A skylight manufacturer asked whether its tested skylights could satisfy OSHA's opening-guarding rules without a separate rail or cage. OSHA said the submitted test data suggested a properly installed skylight would prevent falls through the opening, but actual effectiveness had to be evaluated in use. OSHA did not approve the product and labels the letter an archive document.

Dear Mr. Heather:

This is in response to your December 9 letter requesting a statement of compliance from the Occupational Safety and Health Administration (OSHA) for your skylights.

OSHA neither approves nor endorses products or work practices, but when provided with adequate information, it can offer an opinion as to whether or not they afford compliance with certain regulations. We have reviewed the skylight test data enclosed with your letter and it appears that if the skylights are properly installed, they would prevent an employee from falling through the skylight and therefore the employer would be in compliance with OSHA's skylight opening guarding requirements.

Please be aware, however, the effectiveness your system can only be determined by a health and safety professional observing it in actual use under specific circumstances. Therefore, OSHA provides this review only with the understanding that no mention be made of our review in any advertising or promotional material.

If we can be of any further assistance, please contact me or Mr. Dale Cavanaugh of my staff at (202) 219-8136.

Sincerely,
Roy F. Gurnham, P.E., J.D.
Director
Office of Construction and Maritime
Compliance Assistance
