7. It you use tagout devices, you must prove to do so _____.a. prevents inadvertent exposure to equipment isolation
b. may be successfully used to warn employees
c. provides safety equivalent to lockout
d. will provide a minimum level of employee protection6.8 Verifying Machinery or Equipment Isolation
Each authorized employee must place his or her personal lock on each energy-isolating device before
beginning service work. Service work involving many workers and many energy-isolating devices can
make traditional lockout complicated.
Before any work begins on machines or equipment that have been locked out or tagged out, an
authorized employee must verify that the machine or equipment has been properly isolated and de-
energized. To do that, the authorized employee will attempt to turn the equipment or machinery on by
cycling the energy isolation devices.
Attempting to restart the equipment is one way to confirm isolation; however, the authorized person
should also test, as necessary, all components ensure they have been properly discharged, hazardous
heat has dissipated, and excessive pressures have been relieved (zero-energy states).
Best Practice: Some companies refer to their energy control program as "Lock, Tag, Try" or "Lock, Tag,
Test" to emphasize this important verification step.
8. To properly confirm isolation of equipment, what should the authorized employee do in
addition to attempting to restart the equipment?a. Identify the equipment to be isolated
b. Ensure proper documentation of LOTO steps
c. Get permission to begin servicing or maintenance
d. Test all components for zero-energy states
