Every SOP generated from this template cites the paragraphs below, with a plain-language summary of what each one requires. Citations are informational and are not legal advice.
| Standard | Title | What it requires |
|---|---|---|
| 29 CFR 1910.147(f)(3) | Control of hazardous energy: group lockout or tagout | When servicing is performed by a crew, group lockout or tagout must give each authorized employee protection equivalent to a personal lockout device. One authorized employee is given primary responsibility for a set number of employees working under a group device, that employee ascertains the exposure status of the crew, and each authorized employee affixes a personal lockout device to the group device and removes it only when finished working. |
| 29 CFR 1910.147(f)(4) | Control of hazardous energy: shift or personnel changes | Specific procedures must be used during shift or personnel changes to ensure the continuity of lockout or tagout protection, including an orderly transfer of devices between off-going and oncoming authorized employees so that the machine is never left unprotected. |
| 29 CFR 1910.147(f)(2) | Control of hazardous energy: outside personnel and contractors | When outside servicing personnel work on equipment covered by this standard, the on-site employer and the outside employer must inform each other of their respective energy control procedures, and the on-site employer must ensure its employees understand and comply with the restrictions of the outside employer's program. |
| 29 CFR 1910.147(f)(1) | Control of hazardous energy: testing or positioning of machines | Where lockout or tagout devices must be temporarily removed to test or position a machine or component, a defined sequence must be followed: clear the machine of tools and materials, remove employees from the machine area, remove the devices, energize and proceed with testing, then de-energize and reapply energy control measures before servicing continues. |
