Roof Hatches & Access Openings
Roof hatches (also called scuttles or roof access hatches) let people and materials reach the roof from inside. They are also holes in the floor of the roof, and open hatches are a fall hazard in both directions: people step or fall through them, and tools and materials fall in. Safe access also means a safe ladder or stair and safe handling at the top.

Hazards
- Falling through the opening: an open hatch is a hole in the roof surface. It's easy to step into it, especially backward, carrying a load, in snow or at night.
- Falling from the ladder or stairs to the hatch, especially when carrying tools. See Fixed Ladders and Stairways.
- Hatch cover strikes: a heavy cover, caught by wind, can slam shut or fall on a worker or knock them off the ladder.
- Edge exposure: once on the roof you may be near an unprotected edge. See Roof Work and Warning Lines & Monitors.
- Falling objects: tools and materials dropped through the opening can hit people below.
- Slips: wet, icy or snowy surfaces around the hatch. See Scaffold Weather.
- Stuck or locked hatches that trap workers on the roof or are forced open unsafely. Locked hatches can also lock out emergency egress.
- Roof deterioration: rotted decks and corroded hardware around old hatches.
What OSHA requires
- OSHA treats a roof hatch opening as a hole and requires protection: guardrails, a cover or a fall arrest system where workers could fall through (29 CFR 1926.501(b)(4) for construction; 1910.28 for general industry).
- A cover must be able to support at least twice the weight of employees, equipment and materials that may be placed on it, be secured against accidental displacement, and be marked “HOLE” or “COVER”. See Holes & Floor Openings.
- For ladders and stairs that lead to the hatch, general ladder rules apply: ladder rungs and safe climbing, and 3 feet or more of extension above the landing. Fixed ladders over 24 feet need a fall protection system. See Ladder Basics.
- Employers must train workers to recognize hazards and use the protection. See Fall Protection Basics.
Safe use
- Inspect the hatch and access before use: ladder, handrails, hinges, springs and the lock. Don't use damaged ladders or hatches.
- Before opening, check above and around: wind, ice, snow and any tools on the cover. Use handholds, not the cover edge, for support.
- Raise the cover fully and lock it in the open position with the hold-open arm so wind can't slam it. Some hatches have a spring assist that must be adjusted by a pro.
- Install or use a safety post (ladder extension) or handrail at the top of the ladder to give a handhold for stepping on and off the roof. Use a guardrail around the opening (a hatch rail kit) when the hatch is used often, and keep the gate closed while the hatch is open.
- If working near the opening alone, use a cover, guard or a lookout, and never leave an open hatch unattended. Close and latch the hatch when leaving.
- Hoist tools and materials with a rope or bucket, not in your hands or on your back while climbing.
- Use 3 points of contact on the ladder, and avoid carrying loads up it. Wear non-slip boots and clear snow from the area.
- Plan for the roof: know where the edges are and how to protect yourself. Keep a safe distance and use warning lines or fall protection. See Personal Fall Arrest Systems.
For building owners and managers
- Provide a safe route to the roof: a permanent stair or a fixed ladder with a safety post, rails and cage or ladder safety system where required, and a hatch with a guardrail kit.
- Install roof anchors or guardrails for workers who come to service equipment. See Anchorage Points.
- Keep hatches maintained (hinges, locks, gaskets, springs, ladder bolts) and clear of ice and debris, and don't padlock without a way to open from inside.
- Tell contractors about roof hazards (openings, skylights, fragile areas, edges) and provide access instructions. See Fragile Surfaces & Skylights.
- Make sure the hatch is labeled and fire-rated or smoke vent hatches are not blocked. Ask a professional when replacing hatches.
Roof hatch checklist
- I inspected the ladder, hinges, hold-open arm and lock
- The hatch is locked open while in use, and closed when I leave
- There is a safety post, handrail or guardrail at the opening
- Tools and materials go up on a hoist line, not in my hands
- I know where the roof edges are and have fall protection if needed
