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.

IntroductionSlide3

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.Slide4

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-outSlide5

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.Slide6

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.Slide7

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.Slide8

Mechanism of Injury

Unexpected start-up of the equipment

Release of stored energySlide9

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.Slide10

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

applying lock-out/tag-out guidelinesSlide11

Preparation for Shut Down

applying lock-out/tag-out guidelines

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 equipmentSlide12

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

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

Equipment Isolation

verificationSlide13

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 sourceSlide14

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 valvesSlide15

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 systemSlide16

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

ChemicalSlide17

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.Slide18
