Theater Services Hazard Communication Guide
Basic Stage Safety
- Make sure that all props are safely secured.
- All elevated structures should be clearly marked and safe, and be made of secure construction.
- Stage floors should have adequate resiliency, and and be able to support the weight of props and equipment.
- Stage floors should be kept dry and cleared of slip and fall hazards. Trip hazards should be removed or clearly marked.
- The stage floors should be free of splinters, nails, or worn-out floorboards.
- Backstage stairs should be maintained in good condition, and the stairwells should be properly lit.
- Alleyways should be clear of litter and obstacles.
- The stairs leading up to any catwalk or elevation should have rails, and be marked.
Elevated Platforms and Workspaces
- Elevated work at any level above 6 feet, requires Fall Protection. Protection can generally be provided through the use of guardrails, safety nets, or fall arrest systems. If none of these protection systems is feasible, an alternative written Fall Protection Plan must be written and implemented.
- All floor openings must be guarded by a cover or guardrail on open sides. If there is only a cover, When uncovered, the opening must be attended to by worker. Hinges, handles, and all other hardware must be flush with the floor.
- Moving the "Genie" (or any other manlift equipment) with the basket occupied in the elevated position is strictly prohibited.
- Platforms should be clear of all obstructions, and kept free of oils, grease or water.
- Standard railings consist of a toprail, an midrail, toeboard and posts. Standard railings must be able to withstand 200 pounds in any direction on the top rail.
- All guardrails should be designed for live load of 20 pounds per foot.
- For metal pipe railing, the top rails and midrail should be 1 1/2 inch in diameter.
- If toeboards are required, they should not exceed 3 « inches and bottom clearance should not exceed 1/4 inch.
- If work is done on thrustouts or other elevated surfaces of over 15 feet (e.g. trusses or beams),safety belts and lifelines are needed.
- All individuals working under elevations must wear hardhats and safety shoes.
- Genies, or other hydraulic lift systems can only be operated if all outriggers are in place. If the Genie is positioned directly against the wall, then that side can be without the outrigger, provided the wheels are locked and the rig stabilized.
- OSHA has strict regulations for scaffolding (CFR 1910.29 and 1910.29)
- Scaffolds should be erected and dismantled by experienced personnel using the proper equipment.
- Scaffolds should be constructed so they can support up to 4 times the maximum intended load.
- Scaffolds should follow the 4 to 1 rule, meaning that the maximum height of a free-standing scaffold should be 4 times the narrowest side of the base.Scaffolds must never be erected on top of barrels, boxes, cement blocks, or other unstable support.
- Guardrails and toeboards are required on all scaffolds over 8 feet tall. If the scaffold is less than 45 inches wide, then there must be guardrails on scaffolds over 4 feet.
- Rolling scaffolds (towers) must have proper cross and horizontal bracing, and at least two of four casters or wheels must be swivel type with locking capability. People should not be allowed to ride on manually propelled scaffolds.

- All hand tools must be secured to the worker.
- All individuals working under scaffolds must wear hard hats.
- All individuals working under scaffolds should wear safety shoes.
- Ladders should always be inspected before use to make sure they are in safe condition. Any ladders with broken or missing rungs or other defects shall not be used.
- Never substitute a chair, table or box etc. for a ladder. Never place a ladder on a table or box to increase the height.
- Ladders should not be "spliced" together to create a longer one.
- All personnel using a ladder should face the ladder while ascending and descending.
- A step ladder should be used only in the completely open position, and only climbed on the side with the steps. A step ladder shouldn't be used as a surface from which to work. Workers should not stand on the top step.
- Wooden ladders should not be painted (this can hide splits and defects).
- Ladders should be maintained in good condition, the hardware and fittings, and joints should be securely and smoothly operating. Rungs should be clean of oil, grease or water.
- The ladder feet should be placed on a secure base, and the area underneath the ladder should be kept clear of debris and dry.
- Non-skid safety feet should be installed on all straight ladders before use.
- Manufactured portable wood ladders should have non-slip bases securely bolted or riveted by side rails.
- Ladder side rails shall at least 3 feet above the landing. If this is not possible, then there should be grab rail installed.
- Portable metal ladders should not be used for electrical work. Metal ladders must be marked:"CAUTION: Do Not Use Around Electrical Equipment."
- Straight ladders should be kept on a level surface. They should be placed so that the distance from the wall or surface upon which it leans is about one quarter the length of the ladder.
- Straight ladders should be blocked, tied off or otherwise secured when in use. Otherwise, an assistant wearing a hard hat should brace the ladders for the user. For large ladders, two assistants may be needed.
- Tools and other objects should be secured against falling while using the ladder. Materials should never be left on the ladder, or dropped or pitched to another worker.
- OSHA has specific regulations on tread width and rung distance for fixed ladders.
- Fixed ladders over 20 feet in height must be caged.
- If there are ladder safety devices, then a landing platform is not required. Examples of these are a wire rope going along the middle of the ladder, or a notched rail device used in conjunction with a friction operated safety harness.
- Because a fixed ladder rests on a wall, these ladders can be installed at a steeper angle than portable ladders.
- The operation, maintenance, and repair work on rigging equipment should be done by properly trained and qualified persons. They should be knowledgeable in operation and functioning of the equipment, safe use, routine maintenance, operation of safety devices, possible dangers during proper and improper operation, and emergency procedures.
