The Occupational Safety and Health Administration’s 2025 Top 10 most frequently cited workplace safety violations placed Control of Hazardous Energy (Lockout/Tagout) at No. 4, recording 2,177 violations. Plastic products manufacturers and machine shops topped the list of industries cited for LOTO violations, but industries less traditionally associated with heavy machinery are increasingly seeing citations as well.
Violations commonly involve missing lockout devices, inadequate training, or failure to develop written hazardous energy control procedures. As OSHA emphasizes, controlling hazardous energy is critical: without it, workers face crushing, amputation, or fatal injuries.
The renewed National Emphasis Program (NEP) on Amputations in Manufacturing, which remains in effect through June 2030, continues to target Lockout/Tagout and machine guarding practices across manufacturing sectors. Employers with high inspection numbers related to LOTO or a history of employee-reported amputations face heightened scrutiny.
The Three Pillars of Lockout/Tagout Compliance
To build a robust hazardous energy control program, organizations should focus on three core areas:
1. Comprehensive Written Procedures
Machine-specific LOTO procedures must identify all energy sources, outline step-by-step shutdown and isolation protocols, and specify verification methods. OSHA 29 CFR 1910.147 requires employers to establish an energy control program and utilize procedures for affixing appropriate lockout or tagout devices to energy-isolating devices.
2. Periodic Inspections and Documentation
OSHA mandates that lockout/tagout procedures be inspected at least annually to ensure all steps are followed correctly. Inspections must include interviews with authorized employees and a written evaluation of the program’s effectiveness.
3. Effective Training
Generic training is not enough. Workers need machine-specific training that covers how to lock out the specific equipment they work on, how to release stored energy, and how to achieve a zero-energy state before beginning maintenance. Authorized employees who perform lockout/tagout must have the training, knowledge, and experience specific to the machinery they service.
Industry Outlook and Emerging Standards
The industrial safety landscape continues to evolve. The release of ANSI/ASSP Z244.1-2024—The Control of Hazardous Energy – Lockout, Tagout, and Alternative Methods—provides updated guidance on hazardous energy control requirements. Internationally, new standards such as EN 17975:2025 offer additional frameworks for managing risks related to energies and fluids during maintenance activities.
Recent technological advancements extending to computer-based controls of hazardous energy are also prompting OSHA to review its existing LOTO standard for potential updates.
