2. Introduction
Most accidents are caused by the uncontrolled release of hazardous energy. Many of these accidents can be prevented by proper lock-out/tag-out procedures.
OSHA’s standard is designed to prevent needless deaths and serious injury to workers by controlling hazardous energy.

3. Training Overview
This training is intended to provide a general overview of Lock-out/Tag- out Systems used in today’s workplace.
This awareness information will not provide specific direction in using lock-out/tag-out in confined space rescue operations.

4. Course Objectives Define what is lock-out/tag-out
Determine when lock-out/tag-out should be used
Define energy as it applies to this area
Apply lock-out/tag-out guidelines
Describe procedures for removing lock-out/tag-out

5. Lock-Out
A disconnect switch, circuit breaker, valve or other energy isolating mechanism is put in a safe or “off” position.
A device is often placed over the energy isolating mechanism to hold it in a safe position.
A lock is attached so the equipment cannot be energized.

6. Tag-Out
In a tag-out, the energy isolating device is placed in a safe position and a written warning is attached to it. All lock-out/tag- out materials are supplied by the employer.

7. When
Lock-out/tag-out is necessary whenever you are performing service or maintenance around any machine where you can be injured.
When placing any portion of your body in a position that may be caught in moving machinery
Any work in or near electrically charged machinery.

8. Mechanism of Injury Unexpected start-up of the equipment
Release of stored energy

9. What is Energy?
Energy can be defined in many areas. For the purposes of these guidelines, energy is defined as the following:
Energy is the movement or the possibility of movement
Whenever the power switch is “on” or “off”, energy as some sort is always present in any powered equipment
Energy can come from the force caused by the motion of an object, or potential energy, or force stored in an object that is not moving.

10. applying lock-out/tag-out guidelines Preparation for Shut Down
Before you turn off any equipment, in order to lock or tag it out, you must know:
The type and amount of energy that powers it
The hazard of that energy
How the energy can be controlled

11. applying lock-out/tag-out guidelines Preparation for Shut Down
Shut the system down by using its operating controls.
Follow the proper procedure which is right for that equipment.
Assistance from employees knowledgeable with the equipment

12. Equipment Isolation Equipment Isolation
Operate all energy isolating devices so the equipment is isolated from its energy source
Be sure to isolate all energy sources, secondary power supply, as well as the main one
Never pull an electrical switch while it is under load
Never remove a fuse instead of disconnecting
Equipment Isolation
verification
Make sure all danger areas are cleared of personnel
Verify that the main disconnect switch or breaker can’t be moved to “on” position
Press all start buttons and other controls on the equipment
Shut off all machine controls when testing is finished

13. Application of Lock-Out/Tag-Out
Isolating devices are to be locked, tagged or both
Use only standardized devices supplied by your employer
If tags are used instead of locks, attach them at the same point as a lock or as close as possible
If no tags available, post a firefighter at the energy source

14. Control Stored Energy
To guard against stored energy residual; do any of the following.
Inspect the system
Relieve trapped pressure
Release tension on springs
Block or brace parts that may fall
Gravity
Bleed the lines and leave vent port open
Process piping systems and close valves

15. Removing Lock-Out/Tag-Out
Contact Incident Command
Remove only the tags you put in place
Make sure equipment is safe to operate
Remove all tools from work area
Safeguard all employees
Conduct a head count to assure everyone is clear of the equipment and make notification that lock-out/tag-out is being removed
Follow a check list if there are required steps to re-energize the system

16. Factoids
According to OSHA, how many workplace deaths are attributed to improper use of lock-out/tag-out annually?
According to OSHA, 2% of workplace deaths could be avoided by proper implementation of lock-out/tag-out procedures.
What are the four major types of energy sources which require lock-out/tag-out?
Electrical
Mechanical
Hydraulic
Chemical

17. They must be reviewed annually in the workplace.
Factoids
What is the last step of the lock-out/tag-out procedure?
Verify the isolation of energy and assure stored energy has been released.
How often should lock-out/tag-out procedures be inspected?
They must be reviewed annually in the workplace.
