OSHA 29 CFR 1910.147 is the federal standard governing the control of hazardous energy (lockout/tagout) for general industry in the United States.

Question 2

What is the role of an 'affected employee' in a Lockout/Tagout program, as distinct from an authorized employee?

Accepted Answer

An affected employee operates or works in an area where LOTO is applied but does not perform the servicing

Answer

Affected employees operate or use machines subject to LOTO but do not perform the servicing; they must be trained to recognize LOTO and must not attempt to restart locked-out equipment.

Question 3

A contractor crew arrives to perform maintenance on equipment already covered by a plant LOTO. What must the host employer (Work Permit Receiver side) do?

Accepted Answer

Coordinate with the contractor to ensure their LOTO program provides equivalent protection and that both parties are informed of each other's procedures

A hydraulic press has both electrical energy (motor) and stored hydraulic pressure; both must be isolated and the hydraulic system bled or mechanically blocked before servicing.

Accepted Answer

A warning not to operate the equipment, the identity of the employee who applied the tag, and contact information
