29 CFR Part 1910
[Docket No. S-012A]
RIN 1218-AA53

Control of Hazardous Energy Sources (Lockout/Tagout)

AGENCY: Occupational Safety and Health Administration, (OSHA).

ACTION: Final rule.

SUMMARY: The Occupational Safety and Health Administration (OSHA) is issuing a standard detailing safety requirement for the control of hazardous energy as a new 1910.147. This standard addresses practices and procedures that are necessary to disable machinery or equipment and to prevent the release of potentially hazardous energy while maintenance and servicing activities are being performed. The standard requires that lockout be utilized for equipment which is designed with a lockout capability except when the employer can demonstrate that utilization of tagout provides full employee protection. For equipment which was not designed to be locked out the employer may use tagout. In addition, the standard also supplements and supports the existing lockout related provisions contained elsewhere in the general industry standards by providing that comprehensive and uniform procedures be used for complying with those provisions. This standard applies to general industry employment under 29 CFR part 1910, but does not cover maritime, agriculture, or construction employment. The standard also does not cover oil and gas well drilling; the generation, transmission and distribution of electric power by utilities; and electrical work on electric conductors and equipment. These will be the subjects of separate rulemaking efforts.

The standard contains definitive criteria for establishing an effective program for locking out or tagging out energy isolating devices and requires training for authorized and affected employees. The standard requires the employer to implement the specified procedures, and to utilize effective control measures based on the workplace hazards that are encountered. OSHA expects that this standard will prevent approximately 122 fatalities, 28,400 lost workday injuries and 31,900 non-lost workday injuries a year.

This rule, 1910.147, is being placed in Subpart J of part 1910. The present 1910.147 is redesignated as 1910.150 to allow for the new section.

DATES: This final standard shall become effective October 31, 1989, except for paragraphs (c)(4), (c)(7), and (f)(2), of 1910.147 which contain information requirements currently under review at OMB. A document announcing the effective date of the recordkeeping portions will be published at a later date in the Federal Register.

ADDRESS: In accordance with 28 U.S.C. 2112(a), the Agency designates for receipt of petitions for review of the standard, the Associate Solicitor for Occupational Safety and Health, Office of the Solicitor, Room S-4004, U.S. Department of Labor, 200 Constitution Avenue NW., Washington, DC 20210.

For FURTHER INFORMATION CONTACT: Mr. James F. Foster, Occupational Safety and Health Administration, Room N3649, U.S. Department of Labor, Washington, DC 20210, (202) 523-8148.
