Osha standard 1910.147
The OSHA Standard 1910.147, also known as the Control of Hazardous Energy or Lockout/Tagout (LOTO) standard, is a critical regulation designed to protect workers from unexpected energization or startup of machines and equipment during servicing and maintenance activities.
This standard outlines specific practices and procedures to ensure that hazardous energy sources are isolated and rendered inoperative.
It applies to a wide range of industries and machinery, requiring employers to implement comprehensive energy control programs. By enforcing proper lockout and tagout procedures, OSHA 1910.147 helps prevent serious injuries and fatalities, ensuring workplace safety and regulatory compliance.

OSHA Standard 1910.147, formally known as the Control of Hazardous Energy (Lockout/Tagout) standard, establishes requirements to safeguard workers during service and maintenance of machines and equipment where unexpected energization or startup could cause injury.
This regulation mandates the use of lockout/tagout (LOTO) procedures to de-energize machinery and prevent the release of stored energy, such as electrical, mechanical, hydraulic, pneumatic, chemical, or thermal sources.
Employers are required to develop, implement, and enforce an energy control program that includes written procedures, employee training, periodic inspections, and the proper application of lockout and tagout devices.
The standard applies to a wide range of industries and covers servicing and maintenance activities where workers are exposed to hazardous energy sources, ensuring that equipment is properly isolated and cannot be inadvertently re-energized while work is being performed.

A compliant LOTO program under OSHA 1910.147 must include several core elements: written energy control procedures, comprehensive employee training, and periodic program inspections.
Written procedures detail the specific steps for shutting down, isolating, locking or tagging, and verifying the de-energization of each machine or piece of equipment. These procedures must clearly identify the type and magnitude of the energy source, the methods used to isolate it, and the responsibilities of authorized and affected employees.
Authorized employees are those who perform maintenance and are trained to implement LOTO, while affected employees operate or use the equipment and are trained on the purpose and function of the energy control program. Regular audits, conducted at least annually, verify that procedures are being followed and that employees remain knowledgeable about safe practices.
Differences Between Lockout and Tagout Devices
While often used together, lockout devices and tagout devices serve distinct purposes under OSHA 1910.147.
Bank racial discriminationLockout devices are physical restraints, such as padlocks or valve locks, that prevent the operation of energy-isolating devices and ensure that equipment cannot be energized until the lock is removed. Tagout devices, on the other hand, are prominent warning labels (tags) that indicate that equipment is not to be operated until the tag is removed.
Tags alone are considered less protective than locks because they provide only a warning and do not physically prevent energization. OSHA permits tagout-only procedures only when they provide full protection equivalent to lockout, which generally requires additional safety measures and is only allowed under specific conditions.
Application, Verification, and Removal of LOTO Procedures
The proper application of LOTO procedures involves a sequence of steps: notification of affected personnel, shutdown of the machine, isolation from all energy sources, application of lockout/tagout devices, release of stored energy, and verification of de-energization.
Verification is a critical step and requires checking that zero energy is present, typically through testing or operating controls after isolation. Removal of devices must follow a defined protocol that includes ensuring that all tools are removed, machine guards are reinstalled, and all employees are safely positioned.

| Element | Description | OSHA Requirement |
|---|---|---|
| Written Procedures | Documented steps for safely isolating energy sources for each machine. | Mandatory for each piece of equipment covered under 1910.147. |
| Employee Training | Different training for authorized and affected employees. | Initial and retraining required when procedures change or inspections fail. |
| Periodic Inspections | Annual reviews of LOTO procedures and employee adherence. | Must be conducted by an authorized employee not involved in the procedure. |
| Energy Isolation | Use of lockout devices to physically prevent energization. | Preferred over tagout unless full protection is ensured. |
| Verification of Isolation | Confirming that zero energy is present before beginning work. | Required before any maintenance or servicing begins. |
Frequently Asked Questions
What is OSHA Standard 1910.147?
OSHA Standard 1910.147, also known as the Control of Hazardous Energy (Lockout/Tagout), sets requirements to protect workers from unexpected energization or startup of machines and equipment during servicing or maintenance. It mandates procedures for shutting down, isolating, locking out, and tagging energy sources to prevent injuries. Employers must develop and implement written energy control programs and provide employee training.
Who is covered by OSHA 1910.147?
OSHA 1910.147 applies to general industry employers and their employees who perform servicing or maintenance on machines or equipment where the unexpected energization, startup, or release of stored energy could cause injury. This includes workers such as maintenance personnel, machine operators, and repair technicians. It does not typically cover construction, agriculture, or oil and gas well drilling unless similar maintenance tasks are performed.
What are the key requirements of a Lockout/Tagout program?
A Lockout/Tagout program under 1910.147 must include written procedures, employee training, and periodic inspections. Employers must identify energy sources, use lockout devices to isolate them, and ensure only authorized employees apply or remove locks. Each lock must have a tag identifying the worker. Procedures must outline safe shutdown, isolation, and verification of zero energy before maintenance begins.
How often must Lockout/Tagout procedures be inspected?
OSHA requires that Lockout/Tagout procedures be inspected at least annually. These inspections must be conducted by an authorized employee who is not the one using the procedures. The inspection verifies that the energy control procedures are being followed correctly and that employees understand their roles. Any deficiencies found must be corrected immediately to ensure continued compliance and worker safety.
