For additional safety rules about woodworking machinery, consult Part 213 of Section 29 CFR 1910, OSHA Regulations. Mechanical power-transmission apparatus Machinery equipped with belts, flywheels, chain drives, cranks, connecting rods, and shafting must be equipped with guards to protect employees from the moving parts. The integrity of the guards is weakened with time through vibration, abuse, and incomplete reinstallation after removal for maintenance.
Safety is maintained by inspecting the integrity of the guards prior to use and during operation.
If safety deficiencies are detected, the equipment must be shut down and tagged out until repaired and tested. The OSHA regulation for transmission apparatus contains some general and many specific rules. For additional rules about mechanical power-transmission apparatus, consult Part 219 of Section 29 CFR 1910, OSHA Regulations.
