Unprotected holes in the floor, deck, or roof have resulted in injuries, and even fatalities, in the construction industry. Proper planning and personal attention, however, can prevent falls through openings.
- If you make a hole, guard it. Before cutting a hole, barricade the work area to keep people out.
- If the hole must be open, install permanent barricades around the perimeter. Like railings around the edge of a building or stairwell, barricades around a hole should be a minimum of forty-two inches high, contain a mid-rail, and maintain the capability of withstanding a 200 pound load. Toe boards are recommended at all times and are required if anyone is going to work under the hole.
- If the hole is not guarded, it must be covered. The cover must be capable of supporting at least a 200 pound load, be larger than the opening, secured against displacement, and labeled “Floor Opening, Do Not Remove”. If possible, make a round hole and a larger round cover. An oversized round cover cannot fall through a smaller round hole.
- Never cover a hole with any type of non-substantial material such as paper, cardboard, or plastic.
- Exercise extreme caution while walking over protective paper or plastic. A hole may be lurking underneath. Step very tentatively. If you find a hole, immediately expose it for others to see, barricade it or post someone to warn others of the danger, and immediately notify your supervisor. Even shallow holes can cause injuries.
- Plastic skylights and smoke vents are very popular. You should never stand or sit on a skylight. They are not made to support your weight. If installing skylights, protect the openings as described above until installation is complete.
