Hazardous energy sources• Evaluate machines,
equipment, and processes
• Develop energy control plan
1a
Hazardous energy sources• Look for all
sources of energy
• Identify secondary and stored energy sources
1b
Why lockout/tagout is necessary
• Maintenance/ servicing operations often require employee to place part or all of his/her body into machine’s point of operation
2a
• Prevents injury due to unexpected startup of equipment or released energy
Functions covered by lockout/tagout• Servicing of machines and
equipment
• Performing maintenance on equipment and machinery
• Normal operations
4a
Preparation for shutdown
• Authorized employees locate all energy sources
• Authorized employees inform all affected persons
5a
Shutdown procedure• Each piece of
equipment or machine must be shutdown according to written energy control procedures
• Orderly shutdown avoids additional or increased hazards
6a
Shutdown procedure• Authorized employee uses shutdown
procedures that are established for the machine
6b
Isolating machinery from its energy sources• Type of devices to
be used
• Placement of isolating devices
7a
8a
Releasing stored energy• Authorized employees check for
and relieve:• electrical energy capacitors• residual pressure in lines and pipes
Application of lockout/tagout devices• Positioning of
lockout/tagout devices
• Only authorized employees can attach the devices
9a
Verification procedures
• Authorized employee verifies that all locks and tags are in place
• Authorized employee tries to operate the equipment
10a
Restoring energy to the equipment/machine• Authorized
employees remove tools from the area, replace guards
• Authorized employees ensure that all employees are safely positioned or removed from the area
11a
Restoring energy to the equipment/machine• The authorized
employee who applies the lock is the only one who can remove it
• Special requirements for testing and positioning equipment
11b
Lockout devices• Authorized employees
may never use someone else’s lockout device
• The lock must identify the person who applied it
12b
Tags• The attachment means for a tag
must be:• non-reusable• attachable by hand• self-locking and non-reusable with
