Lockout/tagout Safety Rules

The lockout/tagout standard requires your employer to establish a program to prevent the unexpected startup of machinery or the release of stored energy while you perform maintenance. Before you perform servicing, your employer must ensure the equipment is completely DE-energized and locked out so it cannot be turned on while you are working on it.

Under 1910.147(c)(4), your employer must develop and document specific procedures for shutting down, isolating, and securing equipment. This includes using locks or tags on energy isolating devices and verifying that the machine is truly dead before you begin work. These steps are mandatory for any activity where you might be exposed to hazardous energy.

This regulation applies to you if you work in general industry and perform maintenance or servicing on machines. It covers roles like mechanics, machine operators, and maintenance technicians in manufacturing, food processing, and industrial facilities. It does not apply to construction, agriculture, or maritime operations, which have their own specific safety standards.

OSHA frequently cites employers for failing to develop written energy control procedures as required by 1910.147(c)(4). Other common violations include failing to train you on the specific hazards of your machines or neglecting to conduct the mandatory annual periodic inspection of the energy control program.

In your workplace, these violations often look like a manager skipping the lockout process to save time during a quick repair. It also occurs when you are given a machine to service without being trained on how to identify all energy sources, or when your employer fails to provide the necessary locks and tags to secure the power source.

Violations of 1910.147 are frequently classified as serious, as they often lead to life-altering injuries or fatalities. OSHA conducts inspections triggered by your complaints or reports of severe accidents. Because this is a high-priority standard, fines can be substantial, especially if your employer has a history of repeat violations or demonstrates a willful disregard for safety protocols.

You have the right to a workplace free from recognized hazards, including the risk of being crushed or electrocuted by machinery. If your employer fails to provide proper lockout equipment or training, you have the right to file an OSHA complaint. You are also protected from retaliation under Section 11(c) of the OSH Act if you report these safety concerns.

If you were injured because a machine started unexpectedly, document the equipment involved and whether any lockout procedures were in place. Preserve any evidence of missing training or faulty equipment. An attorney can help you determine if an OSHA violation supports your Workers' Compensation claim.
