When more than one employee works on equipment that must be locked-out in accordance with...

OSHA’s Control of Hazardous Energy (Lockout/Tagout) standard, 29 CFR 1910.147, requires that each authorized employee shall affix a personal lockout device to the energy-isolating device when they are working on equipment. This ensures that energy cannot be restored until every individual has removed their own lock, thereby directly protecting each worker.

Correct (D): The standard explicitly describes the use of a multiple lockout device (commonly called a hasp), where each employee applies their own personal lock. No lock may be removed until the individual’s work is complete.

Incorrect Options:

A: Listing multiple names on a single lock/tag does not meet OSHA’s requirement for individual control.

B: Providing multiple keys to a single lock defeats the purpose of individual energy control and is not compliant.

C: Commonly keyed locks are prohibited because one employee could remove another’s lock.

Relevance to CHFM Exam (Compliance Domain):

The CHFM exam tests knowledge of OSHA workplace safety standards because healthcare facility managers must ensure compliance in utility and maintenance operations. Proper lockout/tagout procedures are critical for worker safety and regulatory adherence.
