Safety Considerations

Skylights pose an inherent risk of injury or death from fall throughs, and the safety of others is of the utmost importance to VELUX.  VELUX recommends that the customer, building owner or manager use additional protection with the skylight such as an exterior or interior safety cage, to enhance long-term safety.  The building owner or manager is responsible for providing fall protection around the skylight in accordance with OSHA regulations.  VELUX also recommends that the building owner or manager restrict roof access only to personnel who have been cautioned as to the location of the skylights, and warned not to sit, step or walk on the skylights.
