GOM Electrical Safe Practice

Purpose,

Objectives

& Scope

The purpose of this standard is to address shockand arc – flash hazards and to protect personnelfrom these hazards.

To establish the minimum requirements forperforming work safely on or near electricalequipment operating at voltage levels of 50 volts

DC or AC and above. Equipment operating atvoltages less than 50 volts are not normally ashock hazard and are excluded.

To establish uniform procedures for doingelectrical work.

The standard applies to all Chevron (company)and contractor personnel performing and/ormonitoring construction, operational ormaintenance activities at any facility or propertyand/or any joint venture operation, where joint –venture agreements allow its use.





GOM Electrical Safe Practice -2011

Scope

GOMBU Electrical Safe Work Practice is a new version. The file is in

PDF format with the Corporate Standard and the GOMBU Addendum tothe Standard merged together into one file.

The requirements in the Addendum are modifications and are definedand indicated within the first pages of the Standard.

The requirements for electrical workers are more stringent for thesafety of the personnel, but allow the assigned tasks to be performedsafely. All personnel should become familiar with the guidelines whichpertain to the PPE used by Company and Contractors doing electricalwork on Chevron property.

Chevron does not allow energized electrical work without the properapprovals. The GOMBU follows this same practice to protect our workersand create an environment of using “Stop Work Authority” for anysituation where the De-energized state is unknown.





Key Definitions Applying to ElectricalSafety

Q u a l i f i e d El e c t r i c a l P e r s o n – A person who has skills and

knowledge related to the construction and operation of the electricalequipment and installations and has received electrical safety trainingto recognize and avoid the hazards involved. This person shall havethe ability to establish an electrical safe work condition.

A u t h o r i z e d El e c t r i c a l Pe r s o n – An individual who is competent in

isolation of hazardous energy and is capable of recognizing electricalhazards. Examples of personnel who might be authorized electrical

persons for specific tasks are electricians, mechanics, supervisors,operators, and engineers. An authorized electrical person is notnecessarily competent to perform the duties of a qualified electrical

person.

El e c t r i c a l St a n d b y P e r s o n – An electrically qualified or authorized person whose responsibilities are to observe the actions of a person performing a task, ensure his/her safety, assist if in danger, and toexercise stop work authority.





Key Definitions Applying to ElectricalSafety continued:

Electrical Work Procedures

Energized Electrical Work Permit

The Energized Electrical Work permit is in addition to the Permit to Work whendoing energized electrical work. All permit to work requirements need to bemet as well as the Energized Electrical Work Permit which will be checked inSection B of the PTW.

The Energized Electrical Work Permit as of July 2011 shall be approved by the Electrical Engineering Supervisor or Delegate of , and an OS, OIM , DSM or

Delegate of, and when possible, an Operations Representative who ison location and acknowledges that all permit conditions are met and the worksite has been inspected, a n d always 2 Qualified Electrical persons , who are planning and requesting the PTW approvals for the work.

The permit is designed to identify the hazards involved, and identify the PPErequirements. Energized Work needs to be planned in advance because of theamount of danger and the information needed on the permit.

IT IS SAFEST TO DE-ENERGIZE!Use the Flow Chart in the Safe Work Practice to determine the bestpath for the work to be completed.

Electrical Work ProceduresPolicy

• It is Chevron’s policy that no maintenance or construction/installationwork is to be performed on any conductor and/or exposed equipment

parts at 50 volts and above while energized.

Use Lockout Tagout to achieve the electrical safe work condition.

1. De-energize / isolate2. Lock & Tag

3. Test to ensure the absence of voltage

4. Ground conductors when applicable Electrical




Electrical Work Procedures 3 Hazards associated with electricity

Electrical Shock and electrocution are well-known electrical hazards. Butelectricity can also cause burns, fires and explosions. These two serious sourcesof such accidents are Arc Flashes and Arc Blasts.

1. Electrical Shock

For electrical shock to occur, the human body must become part of anenergized circuit. Electrical current will flow whenever it has a complete circuit(path) that returns it either to the source or ground. Electrical current will flowthrough your body if you are part of the circuit.





3 Hazards associated with electricity

2. Arc Flash

When electrical current passes through the air between ungroundedconductors or between ungrounded conductors and grounded conductors, thetemperature can reach 35,000 degrees F, or about four times the temperature ofthe sun. Exposure to these extreme temperatures burns the skin directly andcauses ignition of clothing, which adds to the burn injury. The majority of hospitaladmissions due to electrical accidents are from arc flash burns not shocks. Arcflashes can and do kil l at distances of 10 ft.

3. A rc Blast

The tremendous temperatures of the arc cause the explosive expansion of thesurrounding air and the metal in the arc path. For example, copper expands by afactor of 67,000 times when it turns to a vapor. The danger associated with thisexpansion is one of high pressures, sounds and shrapnel. The high pressures caneasily knock workers off ladders, rupture ear drums, and collapse lungs. The sounds

associated with these pressures can exceed 160 decibels. Finally, material andmolten metal expel from the arc at speeds exceeding 700 miles per hour, fastenough for shrapnel to pass right through the human body.





Electrical Work Procedures Burn Hazards associated with electricity

Electrical Burns

Electrical energy may cause two types of burns. The first i s the electrical burn,which is a burn that results from current flow through the body’s tissues.Contact with an exposed live part will cause this type of burn. This burn is fromthe inside out.

Thermal BurnThe second type of electrical burn is a thermal burn, which results from an arcflash and does not require any contact with the exposed live part. This burn isfrom the outside in, an example is sunburn.






Electrically Rated Gloves

Electrically Rated gloves are used to protect from SHOCK. They are rated by aClass according to the voltage level of protection needed for a task

Class 00 ---- 500 Volts Class 2 --- 17,000 Volts

Class 0 --- 1,000 Volts Class 3 --- 26,500 Volts

Class 1 --- 7,500 Volts Class 4 --- 36,000 Volts

NOTE: Visually inspect and air test rubber gloves before each use and after any event thatcould have resulted in damage to the glove. Air testing involves trapping air in the glove and thensqueezing the glove and checking for pinhole leaks. Gloves shall also be dielectrically tested every6 months, or discarded if not feasible to be sent to be re-tested.

Voltage rated gloves always and leather protectors (task specific) are required anytime aperson is within the Restricted Approach Boundary which are as follows:

1. 50 -300 volts - avoid contact

2. 301 to 750 volts – 1 Foot

3. 751 to 15,000 volts – 2 Feet 2 Inches

4. 15,001 – 36,000 volts – 2 Feet 7 Inches






Electrically Rated Gloves

Gloves need to be tested or replaced every 6 months from date placed into service.If two pairs are purchased, the second pair can be put into service to replace thefirst pair. Shelf life of the not in service gloves is 12 months.

Example; I purchase 3 pair of gloves tested on Jan 1, 2011.

I open one pair and put into service on Jan 15, 2011, This pair is notin compliance after July 15, 2011.

I now open the second pair July 16,2011 since they were not placedin service and use them for 6 months, they are out of

compliance after Jan 16, 2012.

I cannot use the third pair I ordered because they are older than 12months even though they were never in service. The 3rd paircan only be used if in service by December 31, 2011, which isthe end of the 12 month shelf life cycle.

This example will allow an individual to purchase 3 pairs of voltage ratedgloves at the same time, on 1 PD-15 and maximize the time to about 15months between orders.






Personal Protective Equipment (Section 4.5 in the Standard)

Flame Resistant (FR) Clothing and Personal Protective Equipment (PPE) is to beused by the employee based upon the energy exposures associated with the specifictasks.

NFPA 70E tables are used as an alternative to an incident energy analysis whenthe employees are planning tasks, to align exposure levels to PPE requirements.Table 130.7(C)(9) Hazard/Risk Category Classifications and Table 130.7(C)(10)Protective Clothing and PPE.

1. Note: Using the tables, Testing for the presence of Voltage at a levelgreater than 50 volts and less than 240 volts is a Hazard/Risk Category 1and Requires more than the everyday FR clothing

A. Arc Rated Face Shield required

B. Rubber Insulating Gloves required

An Energized Electrical Work Permit will always require the completion of a ShockHazard Analysis, and an Arc Flash Analysis which will determine the PPE required tosafety perform the assigned task.






“Electrical

Qualified Employee” Training

Required to work on energized electrical equipment

For a person to be considered a “qualified employee”, he or she must:

Understand the specific hazards associated with electrical energy and be able toidentify and understand the relationship of such hazards to possible injury.

Be familiar with safety-related work practices, safety procedures, and otherpersonnel safety requirements that relate to the job or task assignments.

Be able to distinguish exposed live parts from the other parts of electricequipment, machines, and processes.

Be able to determine the nominal voltage of exposed live parts.






“ Electrical Qualified Employee” Training

For a person to be considered a “qualified employee”, he or she must:

Know and understand the clearance and minimum approach distances requiredwhen working with the voltages to which he or she will be exposed.

Know proper use of special precautionary techniques, personal protectiveequipment including arc-flash protective equipment, insulating and shieldingmaterials, and insulated tools when required.

Understand induced, static, and impressed voltages, grounding integrity,condition of equipment and structures, and circuit and equipment location.

Be familiar with methods of release of victims from contact with exposed live

parts.Be able to perform cardiopulmonary resuscitation (CPR) and first aid, and befamiliar with applicable emergency procedures related to work and safety.






Qualified Persons

Determine the flash protect ion boundary and, if the boundary is to be crossed, useappropriate arc-flash protective equipment.

For a person to cross the limited approach boundary and enter the limited space, he or shemust be qualified to perform the job/task. An exception to this is that an “authorizedperson” is permitted to cross the limited approach boundary if he or she is specificallytrained for the task to be done.

To cross the r e s t r ic t e d a p p r o a c h b o u n d a r y and enter the restricted space, the qualifiedperson must:

Have a plan that is documented and approved by authorized management.(Energized Electrical Work Permit)Use personal protective equipment appropriate for working on exposed live parts and ratedfor the voltage and energy level involved.

Be certain that no part of the body enters the prohibited space.

Minimize the risk due to inadvertent movement by keeping as much of the body out of therestricted space, using only protected body parts in the space as necessary to accomplishthe work.

To cross the p r o h ib it e d a p p r o a c h b o u n d a r y and enter the prohibited space isconsidered the same as making contact with exposed live parts, the qualifiedperson must:

Have specified training to work on exposed live parts and be approved by authorizedmanagement.

Use personal protective equipment appropriate for working on exposed live parts and ratedfor the voltage and energy level involved.






Work Zones

The space to safeguard personnel. An area temporarily marked off with rope,tape or other barricading devices into which entry is prohibited for all personsexcept those authorized by the Person in Charge of the work zone.

A work zone is established by the Qualified person in charge around the areawhere there are exposed energized electrical equipment. The person in chargehas total authority over this area, before ANYONE enters they must get thePIC’s approval.

Ten Foot Rule

Any person who is NOT electrically Qualified must maintain a minimumdistance of 10 ft from any exposed energized conductor or circuit part. In theGulf of Mexico, this distance can reduced to 4 feet where the system voltagesphase-to-phase is 750 volts or less because the electrical parts are fixed (not

movable).

As the distance between a person and the exposed live part decreases, thepotential for an electrical accident increases. These shorter distances also require higher levels of training and PPE .

Guidance for GFCI Whip Cords and Breakers

• It is Chevron’s policy that personnel use ground fault circuit interrupters when usingcord connected portable power tools and other cord connected equipment.Reference Section 4.7.1 of GOM Electrical Safe Work Practices, and attachment “2009GFCI Application Guidance for Hazardous and Non-Hazardous Areas”, located in theResources section of the OE Manual.

• Before each use of cord connected portable Power Tools, Extension Cords, and othercord connected equipment, a visual inspection should be made.

• A periodical inspection should be made of all extension cords in stock. Never use a cordthat has been taped up or repaired. Always roll up extension cords that have beenunplugged first.

• Observe the following precautions for any cord and plug connected equipment notconnected to premises wiring:

1. Use a tool equipped with a cord containing an equipment-grounding conductorconnected to the tool frame and to a ground on the other end.

2. Use a tool of the double-insulated type.

3. Use a tool connected to the power supply through an isolating transformer with anungrounded secondary.






Substations, and MCC rooms

Storing Materials

Keep substation and MCC rooms free of debris. Do not storeflammable materials ( paper goods, boxes) and equipment notnecessary for electrical systems repair and maintenance in substationand MCCs.

Do not allow substation and MCC rooms that contain energizedelectrical equipment ( 480 V Switch gear) to be public areas, likesmoking areas and offices.

Inspections and Maintenance

Annually inspect substations and MCC rooms to determine thegeneral condition of all equipment, including grounding systems.

Qualified employees should perform the inspection. Equipmentmaintenance scheduling recommendations can be found in NFPA 70B,scheduled in D7I, and/or requested by Electrical Engineers orElectrical Qualified Persons who are first line support for theequipment.
