    Study Notes

    Equipment Lookout and Lockout Procedures in Safety Management Systems

    • Equipment lookout is a system of locks and tags that secure devices to prevent hazardous energy release.
    • Locks are used to secure control devices such as disconnect switches, circuit breakers, valves, and clutches.
    • Hazardous energy includes electric, compressed gas, steam, hydraulic energy, moving parts, or elevated objects that could injure a worker.
    • Equipment lockout is required during maintenance and no work can be done until all parts and attachments are secured, hazards are controlled, and energy isolating devices are locked out.
    • A typical lockout station includes locks, tags that read "do not operate," and hasps for equipment or process lookout.
    • Personal locks assigned to specific individuals are used for lockout, and combination locks should not be used.
    • Shift or personnel changes require an orderly transfer of control of locked-out energy isolating devices.
    • If personal locks are not practical, alternate lockout devices such as metal cable seals with unique identifiers can be used.
    • De-energization and lockout are necessary to prevent the release of energy that could activate moving parts and cause injury.
    • Energy isolating devices must not prevent access to adjacent devices.
    • Effective means of verifying lookout, such as pushing a motor start button or opening bleed valves, must be provided and used.
    • Each worker is responsible for locking out energy isolating devices, removing personal locks, and maintaining control of their keys.
