Osha has set forth regulations codifying the steps building owners must take to protect roof openings including roof hatches.
Osha regulations roof access.
This means that the building owner needs to work with their maintenance staff to develop a safe work plan for any work on the roof.
Conversely they can leave it up to individual contractors to provide safe access to the roof during maintenance activities.
Two osha standards can apply 29 cfr 1910 which governs general industry safety standards and 29 cfr 1926 which governs construction sites specifically.
If the parapet is continuous the access level is the top of the parapet.
The osha general industry standards exclude construction as well as agriculture and marine industries which also have their own standards but both standards can sometimes apply to the same.
Osha considers it a working area.
Parapet ladders must have an access level at the roof if the parapet is cut to permit passage through it.
These standards are flexible providing multiple options for maintaining compliance.
Osha requires that this distance be no greater than 3 5 feet 29 cfr 1926 502 d 16 iv but it may be less for some pfas equipment.
