HEALTH AND SAFETY PROCEDURE 505 – Lock Out Tag Out

1.0 PURPOSE/SCOPE

The purpose of this program is to ensure effective implementation, operation, and recordkeeping of the Westlake lock-out/tag-out program in compliance with 29 CFR 1910.147. The provisions of the Lock- out/Tag-out Program shall apply to all personnel at the facility.

2.0 APPLICATION

This program applies to the servicing and maintenance of machines and equipment in which the

unexpected energization or startup of the machines or equipment, or release of stored energy could cause

injury to employees. This program establishes minimum performance requirements for the control of such

hazardous energy.

A system that is to be opened for work and does not have valves (ie. instrument lines), has valves that

cannot be locked out (ie.. underground water valves) or any other deviation to this procedure requires

approved written procedures to document how the equipment shall be isolated.

NOTE:

It is the responsibility of the owner of the equipment, usually the operations group, to clean, clear,

de-energize and lock out all systems BEFORE allowing any work on the system(s). IF THE

SYSTEM(S) CAN NOT BE ISOLATED, A WRITTEN DEVIATION PLAN (per procedure

WGS-SAF-HSE-P103) IS TO BE EXECUTED WITH MANAGEMENTS APPROVAL AND

ACCEPTANCE FROM MAINTENANCE.

Exclusions can be found in section 5 (WRITTEN ENERGY CONTROL PROCEDURE) of this

procedure

At Westlake Vinyls, all personnel have the right to deny any job that they feel it is unsafe.

NOTE:

This procedure is not intended to cover switchgear and high voltage equipment at or above 480V.

This policy does NOT apply to work on or near exposed electrical conductors and circuit parts falling

within the scope of OSHA standard 1910.333 - Selection and Use of Work Practices. If work must be

performed on or near exposed electrical conductors and circuit parts, refer to the Maintenance Procedure

Electrical Equipment Lockout/ Tag out.

3.0 RESPONSIBILITY

4.0 RECIPIENTS

Westlake Vinyls Intranet http://gvcdocs/Default.asp?

5.0 WRITTEN ENERGY CONTROL PROCEDURE (UNIT MANAGERS)

The Unit Manager shall develop, document, and use energy control procedures to control potentially

hazardous energy before workers perform service/maintenance activities covered by the Control of

Hazardous Energy (Lock-out/Tag-out) Procedure.

These written, machine or equipment specific procedures (505_1) must identify the information that the

authorized employee(s) must know to control hazardous energy (steam, water, natural gas, compressed

air, chemical, electrical, hydraulic, mechanical, and others) during servicing or maintenance. If this

information is the same for various machines or equipment or if other means of logical grouping exists,

then a single energy control procedure may be sufficient. If there are other conditions, such as multiple

energy sources, different connecting means, or a particular sequence that must be followed to shut down

the machine or equipment, then the supervising department must develop separate, machine or equipment

specific, written energy control procedures to protect the employees




EXCLUSIONS

The purpose of this section is to identify activities that will not require LOTO or that are covered

by operational procedures.

GENERAL

Automotive maintenance

Loading and unloading hoses, utility hoses, railcars and general hoses for certain instrument systems

Service activity such as copy machines, soda machines, telephones, etc.

Working on potable water lines (2 inches or less) and replacing water filters with pressure less than 35 pounds.

INSTRUMENT

Sensing/ signal inputs to and signal outputs from instruments, indicating or control devices.

Examples are pressure taps to gauges or switches, impulse lines to transmitters, outputs from

controllers or transmitters, and inputs to valve positioners and actuators interconnecting signals

between instruments or within nest, etc. This does not include flange mounted devices, unless the

system has installed bleed rings for the instrument, or devices used in highly hazardous chemical

services such as sulfuric acid, chlorine, HCl, caustic, hydrogen, bleach, etc.

ELECTRICAL

Checks, tests, verifications, calibrations, etc. of electrical/ electronic circuit condition or

arrangement made during the course of normal repairs or maintenance performed by qualified

Instrument/ Electricians while energized. A large portion of the repair/ troubleshooting work

required in the Instrument/ Electrical discipline is not possible without energizing circuits due to

the nature of electrical circuits and their functions. Examples would include phase voltage level

of a multiple tap transformer, verification of voltage and current indicators, phase rotation tests,

pressure and level transmitters and switches, etc. Additionally, this will include such activities as

changing of lights bulbs fluorescent bulbs, and checking electrical grounds. Work on cord and

plug-connected electric equipment for which exposure to the hazards of unexpected energization

or startup of the equipment is controlled by the unplugging of the equipment from its single

energy source and by the plug being under the exclusive control of the one and only employee

performing the servicing. HVAC (Heating, Ventilation and Air Conditioning Systems Service

checks, additions, removal or transfer of fluids involved in the Freon circuits of building HVAC

units or process refrigeration units.




TEST EQUIPMENT

The use of test or calibration equipment, which utilizes various energies for test or calibration

sources. Examples would be hypots, meggers, transmations, pressure calibrators, etc. Similar to

using multimeter to generate a 4-20mA signal.

OTHER

Minor tool changes and adjustments, and other minor servicing activities, which take place during

normal production operations, if they are routine, repetitive, and integral to the use of the

equipment, provided that the work is performed using alternative measures which provide

effective protection. Hot tap work where the Hot tap procedure is followed.

CHECKING ROTATION/ BALANCING OF MOTORS AND FANS

Testing or positioning of machines, equipment, or components following this sequence:

a. Notify all Authorized and Affected Employees that the equipment is being tested.

b. Have all workers remove their respective locks from the lock box. c. Remove the Operations lock from the lock box. d. Operations shall remove the keys from the lock box and activate the energy source for

testing. e. Perform the test

6.0 DEFINITIONS

Affected employee - An employee whose job requires him/her to operate or use a machine or equipment

on which servicing or maintenance is being performed under lock-out or tag-out, or whose job requires

him/her to work in the immediate area in which such servicing or maintenance is being performed. Many

times this will be the unit operators.

Authorized employee - A person who locks or implements a tag-out system procedure on machines or

equipment to perform the servicing or maintenance on that machine or equipment. An authorized

employee and an affected employee may be the same person when the affected employee’s duties also

include performing maintenance or service on a machine or equipment, which must be locked, or a tag-

out system implemented.

“Capable of being locked out” - An energy-isolating device will be considered to be capable of being

locked out if either it is designed with a hasp or other attachment or integral part to which, or through

which, a lock can be affixed, or if it has a locking mechanism built into it. Other energy-isolating devices

will also be considered to be capable of being locked out if lock-out can be achieved without the need to

dismantle, rebuild, or replace the energy-isolating device or permanently alter its energy control

capability.




“Clearing House Locks” – Locks that are keyed-alike in group. Each set of clearing house locks will be

clearly identified on each lock and on each lockbox. Danger tags may be used but are not necessary on

clearing house locks as the lock can be tracked to the required LOTO checklist which will identify when

and why the lock out is in place. The clearing house locks will be RED (if used by the operations) and

GREEN (if used by the electrical department).

IDENTIFING LOCKS:

Energized - Connected to an energy source or containing residual or stored energy.

Energy source - Any source of electrical, mechanical, hydraulic, pneumatic, chemical, thermal, or other

energy.

Energy-isolating device - A mechanical device that physically prevents the transmission or release of

energy, including, but not limited to, the following: a manually operated electrical circuit breaker; a

disconnect switch; a manually operated switch by which the conductors and, in addition, no pole can be

operated independently; a slide gate; a slip blind; a line valve; a block; and any similar device used to

block or isolate energy. The term does not include a push button, selector switch, and other control

circuit-type devices.

Hot tap - A procedure used in the repair, maintenance, and services activities, which involves welding on

a piece of equipment (pipelines, vessels, or tanks) under pressure, in order to install connections or

appurtenances. It is commonly used to replace or add sections of pipeline without the interruption of

service for air, gas, water, steam, and petrochemical distribution systems.

Lock-out - The placement of a lock-out device on an energy-isolating device, in accordance with an

established procedure, ensuring that the energy-isolating device and the equipment being controlled

cannot be operated until the lock-out device is removed.

Lock-out device - A device that utilizes a positive means such as a lock, either key or combination type, to hold an energy-isolating device in a safe position and prevent the energizing of a machine or equipment.




Master Operations Control Lock - A Red lock with a wrap of yellow tape that is (individually keyed. ie..

one lock and only one key) used by the operations department to secure the lock boxes.

Normal production operations - The utilization of a machine or equipment to perform its intended production function.

Servicing and/or maintenance - Workplace activities such as constructing, installing, setting up,

adjusting, inspecting, modifying, and maintaining and/or servicing machines or equipment. These

activities include lubrication, cleaning or unjamming of machines or equipment and making adjustments

or tool changes, where the employee may be exposed to startup of the equipment or release of hazardous

energy.

Setting up - Any work performed to prepare a machine or equipment to perform its normal production

operation.

established procedure, to indicate that the energy-isolating device and the equipment being controlled

may not be operated until the tag-out device is removed.

Tag-out device - A prominent warning device, such as tag and a means of attachment, which can be

fastened securely to an energy-isolating device, in accordance with an established procedure, to indicate

that the energy-isolating device and the equipment being controlled may not be operated until the tag-out

device is removed.

Worker - The person actually performing work on equipment. The worker can be either a contractor or

Westlake personnel. Each worker must have full control of all energy sources leading to the equipment

for the duration of the work.

7.0 PROTECTIVE MATERIALS AND HARDWARE

Operations shall provide locks, tags, chains, wedges, key blocks, adapter pins, self-locking fasteners, or other hardware for isolating, securing, or blocking of machines or equipment from energy sources.

Lock-out devices and tag-out devices must be identified and the only device(s) used for

controlling energy.

LOTO locks used to protect workers while they are working shall be keyed different with

only one key for each lock.

“Clearing House” locks will be keyed the same, but are ONLY to be used by operations and the electrical department. RED (operations) and GREEN (electrical department).




Clearing House locks are to be keyed alike in small groups. No matter how many groups of

clearing house locks are used, the job MUST be protected by use of ONLY ONE Master

Control Lock.

DANGER:

No worker shall solely use clearing house locks to perform work. Clearing house locks are to be used to isolate the equipment and will not provide the required protection. Individually keyed locks are to be used by each worker providing work on a system that is locked out.

the use of excessive force or unusual techniques, such as with the use of bolt cutters.

Tag-out devices, including their means of attachment, shall be substantial enough to

prevent inadvertent or accidental removal. Tag-out device attachment means shall be of a

non-reusable type, attachable by hand, self-locking, and non-releasable with a minimum

unlocking tensile strength of no less than 50 pounds having the general design and

basic characteristics of being at least equivalent to a one-piece, all-environment-

tolerant nylon cable tie.

The ONLY acceptable attachment to be used at Westlake Vinyls is a RED tie-wrap that is available in warehouse stock that meets the above criteria.

8.0 INSPECTIONS

Routine Inspections

The Safety and Operations departments shall continually monitor performance with regard to compliance with this program and shall correct any deviations or inadequacies observed.

Periodic Inspections

The site will conduct periodic inspections through housekeeping and JTO (Job Task Observation) audits.

Inspections shall:

1. Include review of isolation list(s) for specific equipment to ensure that the isolation lists are adequate to provide the necessary protection.

2. include observing the implementation of an energy control procedure(s).

An authorized employee other than the one(s) utilizing the energy control procedure being inspected shall

perform the periodic inspection.




The employee performing the periodic inspection does not have to observe every authorized employee

implementing the energy control procedure on the machine or equipment on which he or she is authorized

to perform servicing and maintenance.

However, each Westlake Vinyl's employee that utilizes lock out tag out shall be observed and the

observation is to be documented using Safety Standard 505_3 Lock, Tag and Try Evaluation Form.

This procedure must be reviewed annually.

9.0 TRAINING AND COMMUNICATION

Initial Training

The Safety department shall provide orientation and annual training to ensure that the purpose and

function of the energy control program are understood by employees and that the knowledge and skills

required for the safe application, usage, and removal of energy controls are acquired by employees.

Training shall include:

1. Each authorized employee shall receive training in the recognition of applicable hazardous energy

sources, the type and magnitude of the energy available in the workplace, and the methods and

means necessary for energy isolation and control. 2. Each affected employee shall be instructed in the purpose and use of the energy control program. 3. All other employees whose work operations are or may be in an area where energy control

procedures may be utilized, shall be instructed about the procedure, and about the prohibition

relating to attempts to restart or re-energize machines or equipment which are locked out or

tagged out.

Employee Retraining

Retraining shall be provided for all authorized and affected employees annually or whenever there is a

change in their job assignments, a change in machines, equipment or processes that presents a new

hazard, or when there is a change in the energy control procedure.

Additional retraining will be managed by the MOC Procedure

10.0 GENERAL PROCEDURE

Energy Isolation

Implementation of lock-out or the tag-out system shall be performed only by authorized employees.

The 505_1 LOTO Isolation List shall be completed and retained for future use. It shall also be maintained and reviewed by the Unit Trainer until it is no longer valid and a digital record is developed for each piece of equipment under their responsibility.




Notification of Employees

Affected employees shall be notified by the supervising department or authorized employee of the

application and removal of lock-out devices or tag-out devices. Notification shall be given before the

controls are applied, and after they are removed from the machine or equipment.

Tag-out

OSHA has determined that lock-out is a more effective means of ensuring the de-energization of

equipment; it is the preferred method. However, OSHA recognizes that tag-out must be used where the

energy control device cannot accept a lock or locking device. If the energy isolating device is capable of

being locked out, the standard requires that a lock-out be used.

When tag-out systems are approved (See Responsibilities Section of this Procedure), employees shall also be trained in the following:

1. Tags are, essentially, warning devices affixed to energy-isolating devices, and do not provide the

physical restraint on those devices that is provided by a lock. 2. Tags must be attached with a RED cable tie LOTO tie wrap to an energy-isolating means, it is

not to be removed without authorization of the authorized person responsible for it, and it is never to be bypassed, ignored, or otherwise defeated.

3. Tags must be filled out completely. Partially written information or a tag that can't be read due poor penmanship or no ink in pen is not acceptable.

4. Tags must have a means of attachment that shall be substantial enough to prevent inadvertent or accidental removal. Tag-out device attachment means shall be of a non-reusable type, attachable by hand, self-locking, and non-releasable with a minimum unlocking tensile strength of no less than 50 pounds having the general design and basic characteristics of being at least equivalent to a one-piece, all-environment-tolerant nylon cable tie.

5. A RED cable tie-wrap meeting the above requirements is available in warehouse stock.

NOTE:

To determine if tags may be used in the place of equipment locks, two of the following must

agree (Unit Manager or designee, Safety Department and/or Shift Supervisor).

Preparation for Lock-out or Tag-out

Make a survey to locate and identify all isolating devices to be certain which switch(s), valve(s) or energy-isolating devices apply to the equipment to be locked or tagged out. More than one energy source (electrical, mechanical, or others) may be involved.

Sequence of Lock-out Tag-out System Procedures

1. The safe work permit system is designed to notify all affected employees that a lock-out or tag-

out system is going to be utilized and the reason therefore.




2. If the machine or equipment is operating, shut it down by the normal stopping procedure (depress

stop button, open toggle switch, etc.). 3. Operate the switch, valve, or other energy-isolating device(s) so that the equipment is isolated

from its energy source(s). Stored energy (such as that in springs, elevated machine members, rotating flywheels, hydraulic systems, and air, gas, steam, water pressure, etc.) must be dissipated or restrained by methods such as repositioning, blocking, bleeding down, etc.

4. Lock, Tag & Try the energy-isolating devices with assigned individual lock(s) and/or tag(s).

SHARED EQUIPMENT

Some jobs require that valves be isolated in multiple units. The area operator that writes the permit is

responsible for walking the line and identifying all isolation points and shall also be responsible for

notifying the "non-originating" unit(s), and for locking all isolation points involved. All keys for the job

shall be kept in the same lockbox. The lockbox must stay at the originating unit where the permit was

written. Any valves locked in the "non-originating" unit(s) shall have tags with the locks. The tag must

indicate what unit originated the lockout. This will allow the "non-originating" unit(s) whom to call,

should there be questions about the lock out. Locks and tags are to be returned to their "originating"

unit(s) upon completion of the lock out.

CAUTION: Operations and Maintenance Supervisor or Designee JOINTLY are to test

and verify the following steps;

a. After ensuring that no personnel are exposed to potential energy hazard and disconnecting energy

sources: b. Operate the push button or other normal operating controls to make certain the equipment will not

operate. c. Try to start or use the push button of the equipment at least TWO times or other normal operating

controls to make certain the equipment will not operate. d. Return operating control(s) to “neutral” or “off” position after the test.

ATTENTION: Contractors/ Maintenance shall NOT operate any start switch or valve at Westlake Vinyls. Only trained operators are authorized to operate valves

and start switches.

5. If the equipment may be operated from a remote station or computer control system the

authorized employee MUST verify that the equipment will not start remotely

WARNING: Some equipment is capable of being operated remotely and isolation must be verified.

CAUTION: Ensure interlocked equipment is properly isolated and not temporarily disabled by interlock




6. The equipment is now locked out and/or tagged out

NOTE: If more than one person is working on the equipment refer to the Group LOTO section below.

Starting up a piece of equipment that is partially repaired can be dangerous. Therefore, as a preventative

measure, the operator will leave the Master Operations Control Lock Red (red lock with a wrap of

yellow tape) on the lockbox until it is proven that the equipment is prepared for start-up. It is the

responsibility of the person performing the work to communicate to the operator the job status of the

equipment at the bottom of the safe work permit, under the section titled, “exceptions to completion”

section. The work permit will serve as the communication tool between the operator and worker

performing the work and will capture if the “WORK IS NOT COMPLETE" before the end of a shift.

Restoring Machines or Equipment to Normal Production Operations

1. After the servicing and/or maintenance is complete and equipment is ready for normal production

operations notify the affected employee(s) and check the area around the machines or equipment

to ensure that no one is exposed. 2. After all tools have been removed from the machine or equipment, guards have been reinstalled

and employees are in the clear, remove all lock-out and tag-out devices. Operate the energy- isolating devices to restore energy to the machine or equipment

11.0 GROUP LOCK-OUT/TAG-OUT

Group lock-out shall be utilized where complex. In such situations the supervising department may

designate a primary authorized employee, with the primary responsibility for a set number of employees

working under the group LOTO device(s). The primary authorized employee must implement and

coordinate the Westlake LOTO. The primary authorized employee shall place all keys to all locks utilized

in the lock-out inside of a lock box and A Master Operations "Red" control lock placed on the box. This

must be accomplished before a permit is written and before authorized employees participating in the

group LOTO affix their personal lock-out device to the outside of the group LOTO box and before

performing servicing/maintenance activities.

ATTENTION: Operations MUST be present when energy is tested, such as, pressing a "START" button.

In addition to the primary authorized employee, each authorized employee participating in the group

LOTO must be informed of their right to verify the effectiveness of the lock-out measures. Each

authorized employee must be allowed to personally verify that hazardous energy sources have been




effectively isolated, if they so choose. An authorized employee, who opts to verify the effectiveness of the

isolation measures, must perform this verification after affixing his or her personal lock-out device to the

lock box and before performing servicing/maintenance activities.

Each authorized employee shall affix a personal lock-out to the group lock-out device, group lockbox, or

comparable mechanism before he or she begins work, and shall remove those devices when he or she

finishes working on the machine or equipment being serviced or maintained or at the end of the shift,

whichever comes first.

It is imperative that each authorized employee understands the hazards of the work and how to control the

hazards. Furthermore, it is required that authorized employee(s) have knowledge regarding the type and

magnitude of the energy, the hazards of the energy to be controlled, and the procedure to be used to

control the hazardous energy.

12.0 LOCK AND/OR TAG REMOVAL

Each lock-out or tag-out device shall be removed from each energy isolating device by the person who applied the device.

EXCEPTION: Operators are assigned specific areas of responsibility and the RED MASTER CONTROL LOCK KEY will be passed off during each shift change. It is the responsibility of the off-going operator to communicate the LOTO status of each piece of equipment under their assigned responsibility and to ensure the on-coming operator is made aware of the LOTO. The key control will continue from shift to shift until the equipment lock out is removed.

WARNING:

No tag or lockout device shall be forcibly removed without proper authorization. Failure to follow rules may result in disciplinary action up to and including termination.

The supervisor of an employee may remove a lock out or tag out device using the process below.

The supervisor MUST identify the worker(s) whose tag(s) or lockout device(s) are on the equipment.

The supervisor MUST complete Westlake Vinyls' Safety Standard 505_2 Authorization for Removal of Tags / Locks.

An incident report is to be completed by the employee's supervisor and disciplinary action as needed to prevent future occurrence.

PERSONNEL ARE RESPONSIBLE FOR REMOVING THEIR LOCK OUT TAG OUT BEFORE THEY LEAVE THE PLANT PROPERTY

NOTE: If the worker is contacted he/she MUST return to the work site and remove the worker

tag(s) or lock(s). No overtime is provided for this duty.




Operations shall report the LOTO incident to the Unit Manager or the Shift Supervisor indicating what

failed during the incident.

The findings from the incident and recommendations to prevent reoccurrence will be reviewed with all affected personnel.

If the worker cannot be located, attempts shall be made to contact the worker’s supervisor.

PREPARING TO REMOVE THE TAG OR LOCKOUT DEVICE

Verify the equipment is ready to run. Such as, machine guards in place and tools removed.

Fill out “Authorization for Removal of Lockout Device”. (505_2 LOTO Cutting Locks Form)

Remove the tag or lockout device.

NOTE:

Keep the worker’s lockout device, so it can be returned

The lock and tag will be given to the worker’s supervisor. The supervisor will notify the

worker whose lock or tag has been cut and review the incident prior to returning to

work. The worker should get the tag or lockout device(s) and a copy of the removal

form as soon as possible upon returning to the plant property. The ultimate goal is to

ensure the worker’s supervisor (or designee) must notify the worker prior to the worker

commencing any work activity.

The Shift Supervisor is responsible for ensuring the completed Authorization For

Removal of Tags/ Locks form is to be delivered to the Safety Department.

13.0 SHIFT OR PERSONNEL CHANGES

This section is to explain the orderly transfer of lock-out or tag-out device protection between off-going

and oncoming employees, to minimize exposure to hazards from the unexpected energization or start-up

of the machine or equipment, or the release of stored energy.

When work is being performed, under group LOTO, outside the normal shift or working hours a primary authorized employee must be present at all times.

When changing shifts the supervising department may, through an orderly transfer, designate a new

primary authorized employee. This new primary authorized employee must assume the control of the

key(s) involved in the LOTO




It is the responsibility of the each authorized employee to verify effective isolation prior to beginning

work.

When work is performed over a period of time and is not continuous, the primary authorized employee

shall walk through the affected work area(s) to verify effective isolation prior to beginning work. It is not

sufficient for the primary authorized employee(s), to merely review tests in a job briefing and to rely on a

locked box. Rather, each applicable energy isolation device must be verified to assure effective energy

isolation.
