• LO/TO accidents are severe– Average lost work days for
failure to LO/TO is 24 days per injury
– 7% of all fatalities are related to failure to LO/TO

IntroductionIntroduction
• Purpose of the Control of Hazardous Energy Program:
– If a risk exists to any person on unexpected start up, all protective measures are taken to isolate all sources of hazardous energy.
77
ApplicationApplication
Application of Lockout/Tagout is required:– when servicing and/or maintaining machines
or equipment,– if it is necessary to remove a guard or bypass
safety device or interlock,– if employee has the potential to be exposed to
material being processed or machine cycle.

ApplicationApplication
The Lockout/Tagout standard does not apply to:
– Cord and Plug Electrical Equipment• plug under exclusive control of employee
performing servicing or maintenance
– Hot Tap operations..transmission and distribution systems..water,gas, stream or petroleum products
• continuity of service essential• shutdown of system is impractical• documented procedures are followed

LockoutsLockouts
• Individual Lockout:
– Shut down, control off, lockout– Stored energy dissipated, isolated– Operate controls for operation, verify OFF– Work may proceed– If shift changes, individual LO/TO repeated by
next shift

• Long Term Safety Lockout:
– Extended period of time… discontinued ...not longer part of operation
– Long term locks available for use by the responsible person

TrainingTraining
Additional Training for Authorized Persons
– When implementation is required.– Recognition of hazardous energies.– Returning equipment to service.– If questions on application specific actions to
be taken.

TrainingTraining
Additional training required if . . .– new equipment is
introduced– changes in LO/TO
equipment– periodic audit
identifies need
