33. How to establish an energy
control program?
SM

34. The whole process
SM

35. 1. Assessment
Conduct a hazard
assessment by
identifying all equipment
that is used, serviced,
maintained or stored
SM

36. 2. Procedures
Determine Lockout/Tagout requirements for
all equipment, identifying and documenting
all energy sources – and create machine-
specific procedures containing:
 Type of Hazard
 Location on the equipment
 Proper isolation and lockout
device/procedure
 How to dissipate the stored
energy
 How to verify the isolation
After this step, you should have an
energy control program for your facility
and machine-specific procedures
SM

37. 3. Devices

place at least annually to
identify and correct any
deviations or inadequacies.
 Retraining must take place
anytime there is a change in
responsibilities, equipment or
procedures along with new
employees
SM

40. In conclusion…
SM

41. Key Take-Aways
1. Only work on equipment “hot” or “live” if it absolutely
unavoidable
2. Lockout over Tagout
3. Facility specific and machine specific
4. Don’t forget about secondary energy sources or stored energy
5. Use annual inspections, regular training (annually suggested),
and discipline to avoid complacency
6. Lockout/Tagout is only one part of a complete and effective
safety program (safety ID, PPE, etc.)
