Mechanical Power Transmission Guarding

The regulation requires your employer to protect you from the hazards of moving power-transmission equipment. This includes any part of a machine that transfers energy, such as flywheels, shafts, pulleys, belts, and gears, that are located within seven feet of the floor or a working platform.

Under 1910.219, your employer must use specific protective measures like stationary casings, troughs, or guardrails to enclose these parts. For example, 1910.219(c)(2) mandates that horizontal shafting must be enclosed by a casing or trough, while 1910.219(f)(1) requires gears to be completely enclosed or shielded by a standard guard.

This standard applies to all general industry workplaces where mechanical power-transmission apparatus is used. It is particularly relevant in manufacturing, processing plants, and industrial facilities where you operate or maintain heavy machinery, conveyor systems, or automated production lines.

OSHA frequently cites employers for failing to guard nip points and rotating shafts as required by 1910.219(c) and 1910.219(e). Common violations involve missing or damaged guards on belt drives and exposed shaft ends that do not meet the safety requirements for smooth edges or protective sleeves.

These violations often occur when guards are removed for maintenance and never replaced, or when equipment is modified to speed up production. You may be exposed to hazards because a manager failed to install a guardrail around a flywheel or neglected to cover a projecting keyway on a rotating shaft.

Violations of 1910.219 are often classified as serious, as they involve a substantial probability of death or serious physical harm. OSHA inspections are frequently triggered by reports of amputations, crush injuries, or your complaints regarding unsafe machinery. Your employer faces significant fines for these citations, especially if the hazard was known and left uncorrected.

You have the right to a workplace free from recognized hazards, including exposed moving parts. If you believe your equipment is unsafe, you can report the condition to your employer or file an anonymous complaint with OSHA. You are protected from retaliation for exercising these rights under Section 11(c) of the OSH Act.

If you were injured by machinery, document the equipment's condition immediately by taking photos of the missing or broken guards. Report the injury to your supervisor right away and seek medical attention. An attorney can help you understand how an OSHA violation may strengthen your Workers' Compensation claim.
