Lockout/Tagout FAQs

Lockout/Tagout FAQs

I can’t lockout a machine. What do I do?

There are times when locking out a machine’s energy-isolating device is not possible. If you find this is the case, securely attach a tagout device as closely and safely as possible to the energy-isolating device. Make sure it’s immediately obvious to anyone attempting to operate the machine. Additionally, employees must be trained to be aware of the limitations of tagout devices, as they do not provide the physical restraint of lockout devices.

What if I use outside contractors for service and maintenance tasks?

In this case, both the outside contractor and the employer must inform each other of their respective lockout/tagout procedures. The employer must ensure that employees fully understand the contractor’s energy-control program.

What if a shift changes during machine service or maintenance?

This is another instance when standardization is important. A standardized lockout/tagout procedure ensures continuity and should include instructions on the orderly transfer of a lockout/tagout device between incoming and outgoing shifts. If a lockout or tagout device remains on an energy-isolating device from a previous shift, the incoming shift employees must verify that the machine is, in fact, isolated and de-energized.
