Lockout/ Tagout Process


MANAGEMENT&

SUPERVISORYRESPONSIBILITIES


Ethical and moral duty, you have a legal responsibility for safety as a supervisor.

Federal law; supervisors can be held criminally liable for serious injury or death of an employee if proved negligent in their duties.

Fines/prison time for serious and/or willful violations.

Legal Responsibilities


Fine and Jail Sentencefor

Worker Electrocution

Company fined $140,000

Supervisor sentenced to a year in jail

Company had received notification and several warnings that no work was to be accomplished until a power line crossing the job site was de-energized (locked-out and tagged-out).

Supervisor knowing the hazard, directed an employee to drive a dump truck into the hazard area. Then provided instructions to the employee to raise the truck bed under the energized power line.

The employee was severely burned and died on the scene.

Information Source: Safety 21 OSHA-Compliant Workplace - October 2003


Develop company policy for implementing lockout/tagout procedures for the control of hazard energy during maintenance operations.

Management Responsibilities

Train authorized and affected employees on proper use of procedures.

Establish written machine-specific procedures to include applying the locks and tags, release, and notification from lockout.


Supervisors Responsibilities

Ensure initial LOTO training.

Ensure retraining if job assignments change, new machines, control procedures or modifications occurs.

Monitor refresher training.

Enforcement of machine-specific procedures to include applying the locks and tags, release, and notification from lockout.

Check for shortcuts, mistakes, or unsafe work practices.


LOTOPERSONNEL


An Authorized Employee

Or Both !

Your Role

You are either an Affected Employee


Pertains to any employee whose job require them to work in an area where maintenance is performed

Affected Employee

An individual that operates the machinery but does not perform the lockout procedures


Affected Employee Responsibilities

Report all unusual situation to your supervisor or foreman.

Stay clear of the area as much as possible.

Watch out for others in the area.

Never attempt to assist if your not properly trained.

Never interfere or tamper with a lock or tag.


An individual who has been properly trained to use lockout/tagout

procedures on a machinery or equipment that is to be serviced.

Authorized Employee


Authorized Employee Responsibilities Verify the isolation.

Properly plan the job.

Notify all affected employees in the area of work.

Shut down the equipment at the operating controls.

Isolate all energy sources to equipment.

Lock and tag all isolating devices.

Dissipate all stored or residual energy sources.


Could be Both

An authorized employee and an affected employee may be the same person, when the affected employees’ duties also include performing maintenance or service on a machine or equipment that requires lockout tagout procedure.


LOTOENERGY SOURCES


Types of Energy

Electrical Thermal

Mechanical

Chemical Hydraulic

Pneumatic

Could be more depending on machinery type !

Air


Electrical Energy Hazards

Can cause shock and/or fire


Hydraulic Energy Hazards

Energy of liquids under pressure- Pressure can cause parts to move- Rapid release can cause injury- Hydraulic fluid can burn you


Hydraulic values must also be locked out

Next Slide


Holes drilled in handles to lockout with a chain.


Boiler

Cold fluids can

cause severe injury

Thermal Energy Hazards

Energy of Heat /Cold

Hot equipment & fluids willburn you


Pneumatic Energy Hazards

Energy of compressed gasesUncontrolled release can cause injury

Properly vent all systems before starting maintenance


Six-point hasp used to lockout air valve


Pneumatic energy can be very dangerous


Chemical Energy Hazards

Machinery that use any chemicals have energy that can start fires, cause skin burns and generate harmful gases or fumes

Lubricants, Hydraulic fluid, Fuels, Coolants, Solvents


Mechanical Energy Hazards

Two Types

1. Parts that are still in motion

2. Parts that store energy sources


Mechanical Energy Hazard

A chipper or hog can remain in motion long after power is locked out

Parts that are still in motion


Mechanical Energy Hazard

Parts that store energy sources

A plywood press has stored energy by the hydraulic actuators it uses

Position blocks toprevent parts fromFalling or moving


LOTOPROCEDURES


The purpose of lockout/tagout is to prevent energy sources from accidentally being released while a machine or equipment is being serviced.

The ultimate goal of lockout/tagout is to protect the safety and health of employees.

Lockout/Tagout Program

“Over 70% of all accidents come from improperly applied procedures or non-compliance”


OSHA

OSHA requires employers to develop, document, and

implement machine specific procedures for the control

of hazard energy source(s) during maintenance operations.

Machinery Lockout/Tagout

7-step process

2. Shut down equipment

3. Isolate all energy sources 4. Install Locks and Tags

5. Verify stored energy shut-down

6. Verify equipment isolation

7. Release from Lockout

1. Prepare for shutdown


Step 1Prepare for shutdown

Must know what energy sources associated with equipment

Electrical

Hydraulic

Pneumatic

Thermal

Mechanical

Chemical


Step 2Shut down equipment

Use normal shutdown procedure


Step 3Isolate all energy sources

Turn off power at machinery


Turn off power at machinery at electrical circuit breaker boxes


Turn off Air and Hydraulic pressure


Step 4Install Locks and Tags


Remember to put the key in your pocket – never leave it in the lock


Step 5Verify stored energy is shut-down

Ensure saw blades have come to a complete stop before removing guards


Ensure cutter heads are not in motion


Step 6Verify equipment isolation

Try to restart machinery following normal procedures


Machinery is now safe for maintenance operations


Step 7Release from Lockout

Inspect Area and Equipment

Reinstall machine guards

Account for tools and parts

Inform others of equipment start-up


Conduct annual audits to validate effectiveness of the lockout/tagout procedures

Review procedures annually or when required, especially after an accident has occurred.

Additional lockout/tagout requirements:

Maintain an equipment survey that list the equipmentrequired to have lockout/tagout procedures, type(s) of energy sources, and magnitude of energy.
