Roof Hatch Access
Governed by OSHA Regulations 1910.23 & 1910.27, roof top hatches should provide safe egress and ingress through the roof. Hinged and guarded by railings with a standard height of 12 inches, they are in effect a ladderway floor opening, the roof being the floor or platform.
Fixed access options for roof hatch access include ships ladders permanently angled at different degrees, folding ladders, vertical fixed wall ladders and retractable ladders.
Ships ladders are designed for access to roof hatches, mezzanines, equipment lofts and other restricted spaces. They usually include heavy duty aluminum top and bottom brackets for a fixed, permanent installation. Typically, they are available in 60 degrees 70 degrees and 80 degrees with maximum heights varying between 15 feet and 20 feet. They can be specified with or without side rails and with or without extended side rails.
