Lockout/Tag Out is for workers and supervisors who may be required to provide maintenance or repair work on a piece of machinery/equipment. Participants will learn the importance of the need to lockout and how to help worker make educated decisions working on their equipment.
Lockout is a technique used to prevent equipment from being accidentally started and prevent stored energy from being released while an associated machine or piece of equipment is being serviced.
Typically, a padlock or any other appropriate mechanical device that physically prevents the transmission or release of energy is placed on the energy-isolating device that should be in the off or closed position. Energy isolating devices can include the following:
- Disconnecting switches
- Circuit breakers
- Valve handles
A tag will also be placed together with the locking device to explain why the equipment is locked, by whom and for how long.
The Lockout/Tag Out procedures includes:
- Preparation for Shutdown
- Equipment Shutdown
- Equipment Isolation
- Application of Lockout Devices: apply lock and/or tags to all energy isolating equipment. Anything that might restore the flow of energy to the work area must be locked out
- Control of Stored Energy: after locking out/tagging off the equipment the stored energy must be controlled:
- relieving any residual energy
- waiting until moving parts stop
- relieving trapped pressure
- installing ground wires to discharge electrical capacitors
- blocking or supporting elevate equipment
- Verify Equipment Isolation
Training for this course can be arranged through the PAT Institute — topics covered are: how to know when lockout is required, how to lockout as a group, understanding the dangers of hazardous energy and much more! Interested participants or employees should call the PAT Institute at 1-888-501-9272 or visit www.patinstitute.ca for more information.
