Lockout / Tagout

Lockout/tagout agenda

• In today’s presentation, we will discuss the following:

• Terminology

• Energy sources

• Energy control procedures and equipment

• The three stages of lockout:1. Preparation2. Lockout3. Restoration of energy

• Special circumstances:- Multiple employees- Shift change- Emergency lock removal- Contractors

Lockout/tagout: What is it?

Lockout/tagout is a procedure used by authorized personnel to ensure that energy controls are kept in an off or safe position during maintenance and service work.

Lockout/Tagout terminology

•Authorized Employee – employee(s) who is trained and authorized to perform work requiring identification and control of energy sources. Generally, this work is service, maintenance or construction related.

•Affected Employee – employee(s) who does not use lockout/tagout but who works in an area where they will see equipment with locks and tags on energy control devices.

Our critical safety rule

Authorized and affected employee’s alike share one critical safety rule:

The Person Who Applied the Lock is the Only Person Allowed to Remove the

Lock

Energy sources

Energy Sources, present in many machines, include:

Electrical

• Mechanical (moving parts)

• Pneumatic and gas

• Hydraulic

• Thermal (heat or extreme cold sources)

• Chemical (acids, bases, solvents, etc.)

• Stored (energy that is stored even after the control device is locked)

Stored energyMany serious accidents occur because stored energy was not

recognized. Some examples of where stored energy can be found are:

• Charged electrical capacitors• Compressed springs and wound torsion bars• Hot machine parts • Pressurized pipe lines• A machine part that can slide if a catch fails• Many others not listed

ALWAYS CHECK EQUIPMENT TO VERIFY THAT ALL STORED ENERGY SOURCES HAVE BEEN RENDERED

SAFE BEFORE STARTING WORK

Energy control procedures

• We maintain a written Energy Control Procedure for all equipment in our facility. Exception: Single power source machines, which meet several other criteria.

• The Energy Control Procedure lists the following:-The type of energy and the magnitude-The location of the control device for each energy source

• The Energy Control Procedure should be consulted before Lockout/Tagout to assure that all energy sources are identified and put into a safe state

Periodic inspection

•Performed annually

•Review of all Energy Control Procedures (ECP)

•Revise Energy Control Procedures when applicable

•Conduct retraining when ECP requires revision

Energy control equipment

Each authorized employee will be provided with locks and tags:

• Our facility standard is to use locks and tags together

• Only locks and tags supplied by our company are allowed

• Tagout alone is only allowed when an energy control device is not capable of accepting a lock

• Lockout locks are provided with only one key

• Never lend your locks to another person

• Never use lockout locks for purposes other than lockout

• Specialized lockout equipment is available in our facility

Lockout/tagout preparation

To prepare to perform a job requiring Lockout/Tagout you must:

•Review the Energy Control Procedure

•Procure all hardware needed to lockout all energy sources

•Complete all information needed on your tag(s)

•Notify the “owner” of the equipment

•Barricade the work area to ensure safety

Lockout sequence

The sequence to actually lockout the equipment is:

1. Shut down all energy sources using normal procedures2. Lock and tag each energy control device in the off or

safe position (controls that can not be locked can be tagged only-the tag must be as close as possible to the device and readily visible)

3. Dissipate or restrain stored energy4. Verify proper lockout by attempting to restart the

machine Caution: be sure all personnel are clear of the machine

5. Return operating control(s) to off or safe position

Restoration of energy

When the job is completed you must:

1. Inspect the equipment for tools, parts, etc.

2. Replace guards and restore machine controls

3. Notify the “owner” and others in the area of start-up

4. Remove locks, tags, etc.

5. Test the operation of the equipment

6. Release the equipment back to the “owners”

Multiple employee lockout

Whenever more than one employee is working on equipment requiring lockout/tagout, the following rule applies:

• Each employee must have her/his lock on each energy control

• A group lockbox could also be used

Shift change or reassignment

When shift change or reassignment occurs during a lockout/tagout, the following rules apply:

•The off-going employee will review the job with the on-coming employee

•The off-going employee will remove his/her locks/tags

•The on-coming employee will place his locks/tags

•The on-coming employee will verify that all energy controls are in the off or safe position

Always check your lockout/tagout after being away from the job, even after breaks and lunch

In the event that a lock has to be removed when an employee can not be contacted, the following procedure will be followed:

•The decision to remove the lock must be made by a member of management

•Every effort must be made to contact the employee including calling her/him at home

•A member of management will meet the employee at the entrance before the next scheduled work shift

•The cut-off lock will be left with a note on the employee’s bench or tool box

Emergency lock removal

Working with contractors

• Contractors are required to have a program equivalent to ours

• Contractor personnel will be made aware of our procedure, locks and tags

• All of our facility personnel who work with contractors will be made aware of the contractor procedure, locks and tags

• Any problems that you observe should be immediately brought to the attention of the program administrator

Conclusion

• Locks and tags are always used in our facility, except when an energy control device can not accept a lock

• Only facility assigned locks and tags are to be used

• Always check the Energy Control Procedure prior to performing a lockout/tagout - never forget to check for stored energy

• Communicate with all personnel who are affected by the job

• Each employee working on the job must have his/her lock on each energy control device

Never risk accidental energy restoration—lockout!
