OSHA 1910.119(e)(6)

This fails OSHA PSM requirements. OSHA 1910.119(e)(6) explicitly requires that the Process Hazard Analysis be updated and revalidated at least every 5 years. The plant's PHA is now 7 years old and 2 years past the mandatory revalidation deadline. The revalidation requirement exists because process conditions, equipment condition, personnel, and industry knowledge of hazards change over time, even without intentional process modifications. Additionally, incident investigations, near-misses, and new regulatory guidance since the original PHA may reveal hazards not previously identified. The 5-year revalidation is mandatory regardless of whether process changes have occurred.

OSHA 1910.138 / SMACNA Safety Manual

Raw sheet metal edges are razor-sharp and cause severe lacerations. OSHA and SMACNA safety standards require cut-resistant gloves (ANSI A4 or higher) when handling unfinished sheet metal. This is the #1 injury in sheet metal shops.

OSHA 1910.147 / NFPA 70E 120.5

Removing an MCC bucket while the bus is energized exposes the worker to live 480V bus stabs and creates an arc flash hazard. OSHA 1910.147 and NFPA 70E require the MCC to be de-energized and locked out/tagged out before withdrawing any bucket unless the equipment is specifically designed for hot-swap operation.

OSHA 1910.147(d)(6)

OSHA 1910.147(d)(6) requires the authorized employee to VERIFY that isolation and de-energization have actually been accomplished before starting work — by testing for absence of voltage and attempting a normal start. A handle position is an indication, not a verification. Handles break, contacts weld, and the disconnect you opened is not always the one feeding the equipment.

OSHA 1910.147(e)(3)

OSHA 1910.147 requires each lock to be removed by the employee who applied it. Removal by anyone else is permitted only under a specific documented procedure that includes verifying the employee is not in the facility and informing them before they return to work. A master key kept for convenience defeats the single guarantee the standard provides — that your lock is the only thing that can start that machine while you are inside it.

OSHA 1910.212 / SMACNA Safety Manual

Pittsburgh lock seam machines have pinch points that can amputate fingers. Machine guards are required by OSHA and must never be bypassed or removed. SMACNA apprenticeship training specifically emphasizes: never defeat a machine guard.
