Gratings
Attachments
Gratings serve multiple purposes on a rig, including acting as walking surfaces and guarding moving equipment like mud pits or machine parts. All gratings must be securely attached so they do not shift, wobble, or come loose when stepped on. Movement underfoot can cause workers to lose balance and fall. Hinged gratings must have a pop-up handle that lies flat when not in use to avoid creating a trip hazard. These gratings should also include a secure method to hold them open during maintenance tasks to prevent crush injuries from falling hatch covers.
Gratings that cover moving machinery such as belt drives or conveyors must be bolted down at all times. These areas are considered hazardous and must follow a lockout/tagout procedure if the grating needs to be removed for service or inspection. Proper signage or markings must indicate that removal of the guard is restricted and only allowed after the equipment has been safely shut down and locked out.
Condition
Inspect all gratings regularly for damage, especially rust or corrosion, which can reduce the strength and safety of the panel. Damaged or worn gratings may not be able to support the expected weight and could fail during use. Also check for sharp edges, missing sections, or buildup of mud or oil that could cause slips.
Load Rating
Each grating used as a load-bearing surface must have a clearly posted load rating in the area. This ensures that personnel do not overload the walkway or platform during work operations. Gratings must not be bent, cracked, or broken. They should never be temporarily patched with boards, plywood, or other materials that are not rated for structural support. Makeshift repairs can fail suddenly and create serious fall or injury hazards.
