What does the lockout/tagout standard require under 29 CFR 1910.147?

Short answer

The lockout/tagout standard under 29 CFR 1910.147 requires employers to control hazardous energy during servicing and maintenance of machines and equipment. This includes implementing procedures for lockout, tagout, and group lockout/tagout, as well as training employees on these procedures. The standard applies to machines and equipment where unexpected energization or startup could cause injury to employees.

The rule says

The control of hazardous energy (lockout/tagout) standard covers the servicing and maintenance of machines and equipment in which the unexpected energization or start up of the machines or equipment, or release of stored energy could cause injury to employees — 29 CFR 1910.147(a)(1)(i).

"Group lockout or tagout devices shall be used in accordance with the procedures required by paragraph (c)(4) of this section including, but not necessarily limited to, the following specific requirements: (A) Primary responsibility is vested in an authorized employee for a set number of employees working under the protection of a group lockout or tagout device..." (29 CFR 1910.147(c)(3)(ii))

In plain English

Employers must develop and implement procedures to control hazardous energy, including lockout, tagout, and group lockout/tagout. These procedures must be tailored to the specific machines and equipment being used and must include training for employees on the proper use of lockout/tagout devices. The standard also requires employers to ensure that employees understand and comply with the restrictions and prohibitions of the energy control program.

What to do

• Develop and implement a lockout/tagout program that includes procedures for lockout, tagout, and group lockout/tagout.
• Train employees on the proper use of lockout/tagout devices and the procedures for controlling hazardous energy.
• Ensure that employees understand and comply with the restrictions and prohibitions of the energy control program.
• Review and update the lockout/tagout program regularly to ensure it remains effective and compliant with the standard.
