7.1 On our construction projects, we widely use temporary power and portable tools. Hazards arecreated when cords, cord connectors, cord and plug connected equipment, andreceptacles are improperly used and maintained. Generally, flexible cords are morevulnerable to damage than other electrical equipment and deserve special attention. Inaddition, we often work around energized electrical circuits from operating a 120 Vbreaker by properly trained team members to working in cabinets with exposed liveparts by qualified electricians.

7.2 Training

7.2.1 All team members must be trained in the requirements of this policy.

7.2.2 Team members who are required to work within the limited approach boundary asdefined in NFPA 70E must be qualified and have additional training. See 050 ElectricalOperations Program Safety Policy and Procedure for specific training topics required.

7.2.3 Training shall include identifying and understanding the relationship between theelectrical hazard and potential injury.

7.2.4 Training shall be documented with name, date, trainer, and content and sent to theCianbro Training Center for retention through entry into our system.

7.3 Ground Fault Circuit Interrupters (GFCI) for Personnel Protection

7.3.1 The Ground Fault Circuit Interrupter (GFCI) is a fast-acting circuit breaker that sensessmall imbalances in the circuit (5 milliamps or more) caused by current leakage toground and in a fraction of a second shuts off the electricity. The purpose of the GFCIis to provide protection from electrical shock to the user.

A. GFCI protection is required on all 120-volt single-phase 15, 20, and 30 ampreceptacle outlets. The GFCI plug receptacles, panel breakers or cord pigtailsmust be in place before using a cord set so the cord set and all down stream loadsare protected.

B. All 120 volt 15, 20, and 30 amp single-phase outlets, cord sets, and cord and plug

connected equipment shall be protected by GFCI.C. GFCI devices like plug receptacles or cord pigtails are required to be tested each

day before use. This is to be done by the person using the GFCI. The test isperformed by pushing the test button on the GFCI, the reset button will pop outand the electricity will be shut off. This will be verified by having the user plug atool or light into the GFCI, turn the tool switch on and make sure there is no powerto the tool. A competent person may also verify by using a voltage tester to makesure there is no power. A plug-in GFCI tester can be used to test the device forproper trip functions. If the button does not pop out, take the GFCI out of serviceeither by tagging it out or if its a portable device, tag it out of service (out of order,


4/18


for repair, damaged, etc.) and return it to the tool crib for repair by a qualifiedelectrician.

D. GFCI circuit breakers located in electrical panels used to protect outlet circuitsmust be tested at least monthly, after any violent thunderstorm or more often ifrequired by the manufacturer. GFCI circuit breakers tests shall be documented.Know what systems are protected that may be in use, before checking a GFCIbreaker or cord pigtail device.

E. OSHA requires testing of GFCI devices used for personnel protection.F. Refer to Cianbro Electrical Operations Program for GFCI testing procedure.

7.4 Power Cord Inspection Program

7.4.1 Cianbro has a power cord inspection program that requires inspection of all outlets,cord sets, and cord/plug connected tools and equipment cords before use.

7.4.2 Implementation of this program is the responsibility of the supervisor in charge. It is theresponsibility of every team member to verify that each cord set (extension cord) andany equipment connected by cord and plug is visually inspected before each day's usefor defects such as deformed or missing prongs, damaged insulation, indications ofpossible internal damage or incorrect quarterly identification. Equipment founddamaged shall be removed from service, tagged, and not used until repairs have beenmade by a qualified electrician.

7.4.3 The project manager/superintendent or supervisor in charge shall ensure a qualifiedperson is assigned the responsibility to conduct quarterly inspections of all outlets, cordsets, and cord/plug connected equipment. This specifically includes 240 and 480 voltcords and all other cords but does not include those cords that are 120 volt single-phase 15, 20, and 30 amps or those cord sets in storage. The following tests andinspections shall be performed.

A. Conduct visual inspections for external defects and possible internal damage.B. With the use of testers, test to determine correct connections and whether or not

the outlet, cord set, or cord/plug connected equipment is properly grounded.C. Inspections and tests must be performed before first time use, (new equipment or

cords) before equipment is used following repairs or suspected damage andbefore every quarter of each calendar year.

D. Rental or other equipment shall also be inspected and tested in the same way.

7.4.4 Quarterly checks and tests must be accomplished and documented by using the propercolored electrical tape wrapped around the cord approximately three to six inches fromthe male plug end. Remove old quarter tape before applying new color tape.

A. Equipment shall be marked as follows.

Test/InspectionMonth

Quarter Tape Color Memory Code

December Jan, Feb, Mar White Snow/Winter

March Apr, May, Jun Green Grass/Spring

June Jul, Aug, Sep Red Hot/Summer

September Oct, Nov, Dec Orange Foliage/Fall

B. Remove old tape and apply new color each quarter.C. Double-insulated tools, other than 120 volt single-phase 15, 20, or 30 amp, should

also be taped in the same manner to document that a visual inspection has beendone.

D. Electrical equipment that remain in a fixed location like a field office trailer; do nothave to be checked per this power cord inspection program.

E. Quarterly intervals shall not exceed three months. In order to ensure turnover fromquarter to quarter, tests and inspections should start during the month prior to the


5/18


start of the new quarter and should be completed by the first day of the newquarter.

7.4.5 Subcontractors must also show evidence of their assured equipment groundingconductor (AEGC) or GFCI program and method of documenting inspection or checks.They may adopt our electrical program; however, they shall be fully responsible forinspection/testing and controlling their equipment.

7.4.6 Repairs to cord sets or the electrical components of power tools must be made by aqualified electrician. This includes plug and cap connections. The only exception to this

is that qualified persons other than electricians may make repairs to 120 V cordassemblies (repairs to cords and plugs, not internal repairs to power tools) if they havebeen approved through the procedure contained in SD1070 found out on Cianbro.net.

7.4.7 See 9.1 Appendix A for Cianbro Wiring Procedure for Portable Cords.

7.4.8 See SD1070 for Authorized Electrical Cord Repair Person Requirements.

7.4.9 Cable Stripping methods and tools require special planning to avoid personal injuryfrom cuts.Specialty cable/wire stripping tools shall be used whenever possible.Some cable stripper tools that work well are:

A. MK01A, ABECO- cable stripper, 3/8 to 1 inch diameter cableB. Ideal 45-129 - cable stripper, for larger size cablesC. Rotastrip ABECO - cable stripper, works well, blades will brakeD. Stripmaster - cable stripper, works well, less fatigue to wristE. Reflex T, - cable stripper, works well, light and easy to use

7.4.10 Only as a last resort and as determined to be a safer method, shall utility or personalknives be used. A job hazard analysis (JHA) must be completed and justificationdocumented in the activity specific plan allowing the use of utility or personal knives.

A. Cut resistant sleeves and cut resistant gloves shall be used for all cable and wirestripping when using a utility or jack knife.

B. Proper instructions/training shall be given on how to safely strip cable/wire.C. Refer to Safety Policy and Procedure Numbers 017 Hand and Finger Protection

and 031 Personal Protective Equipment for additional information in regard to

working with sharp tools or objects.

7.5 Portable Electric Generators/Welders/Light Stands

7.5.1 Portable electric generating equipment shall be equipped with GFCIs or portable plug-in GFCIs shall be used.

7.5.2 Under the following conditions, the frame of the generator does not need an externalground (such as using a ground rod) if:

A. The generator supplies only equipment mounted on the generator such as lightstands, arrow boards, welders, etc. and/or plug and cord connected equipment.

B. When mounted on a vehicle or barge, the frame of the generator is bonded to theframe of the vehicle or barge, and the generator supplies only equipment located

on the vehicle and/or cord and plug connected equipment.C. The generator is bonded to its supporting frame and if on a trailer or vehicle to theframe of the trailer or vehicle.

7.5.3 In all other cases, generators shall be grounded by a ground rod or connection to thebuilding grounding system as required.

7.6 Temporary Lighting

7.6.1 Temporary area lighting is required to be supplied by its own circuit. Temporary lightingcircuits are not to be used for any other purposes.


6/18


7.6.2 Portable electric lighting used in wet or other conductive locations such as drums,tanks, and vessels shall be low voltage (12 volts or less) or 120 volts protected byGFCIs.

7.7 Special Conditions

7.7.1 Written activity plans must be developed which address the specific work to beaccomplished and all electrical hazards associated with it. Activity plans should bebased on inspection of the work area and elimination, isolation, or control of identified

hazards including Process Safety Management (PSM) consideration. A competentsupervisor must be assigned to coordinate planning and monitor activities. Activityplans must be communicated with all persons associated with the work to be involvedprior to the start of work.

7.7.2 Unanticipated or Unique Electrical Hazards

A. Unique electrical hazards created during work performed by Cianbro teammembers shall be reported to the client including what measures are in place tocontrol the hazard.

B. Unanticipated electrical hazards identified during the work activity shall be reportedto the client including what measures are in place to control the hazard and toprevent the hazardous condition from reoccurring.

7.7.3 Work on Energized Panels or Equipment

A. Work on energized panels or equipment is prohibited. Whenever possible,electrical equipment must be de-energized, tested, and positively locked-out inaccordance with our Zero Energy State Safety Policy and Procedure prior toconducting any work on or around it (Tick Tracers are not to be used whenidentifying or testing for energized conductors.) Energized work will only be done,as an exception, when the work cannot be done with the equipment in anelectrically safe working condition. Only electricians approved by the CianbroElectrical Committee and designated as persons qualified to work on live electricalparts are authorized to perform work in energized panels or equipment. For workon or near live electrical parts reference NFPA 70E Article 130.1 Working on orNear Live Parts - Justification for Work. This indicates that if live parts are not

placed in electrically safe working condition, the work to be performed shall beconsidered energized electrical work and shall be performed by written permissiononly. Unqualified workers are not allowed in these areas unless the space hasbeen placed in an electrically safe working condition.

B. A completed Cianbro Energized Work Permit is required. A detailed activity plandeveloped with review and input by a qualified electrician is also required. RequiredPPE and insulated tools (with current inspection date if applicable) must be usedby the qualified electrician when working on or around energized circuits whereincidental contact or an arc flash could occur.

7.7.4 Work on live circuits will require using specialized equipment and protective clothingfollowing OSHA, NEC, and NFPA 70E guidelines.

A. All insulating personal protective equipment must be inspected before use each

day and after any incident that could possibly have damaged the PPE.B. Rubber insulating PPE must be tested periodically. Refer to 050 ElectricalOperations Program Safety Policy and Procedure for specific intervals (not toexceed 6 months for gloves or 12 months for other insulating PPE).

7.7.5 Work on or adjacent to live circuits in confined spaces or enclosed areas with limitedspace will require the use of protective shields, barriers, or insulating materials toprevent team members from inadvertently touching electrical hazards. Ladders used foraccess to such areas must be non-conductive. Protective barriers must also beconsidered if team members are required to work with or handle conductive materials


7/18


adjacent to electrical hazards. Adequate lighting must always be provided in areas thatcontain live electrical parts.

7.7.6 There must be a minimum of two Cianbro team members, one being a qualifiedelectrician, working at all times in an Electric Room when panels are open. No teammember will ever be left alone.

7.7.7 All other work in an Electric Room will be evaluated for electrical hazards by a qualifiedelectrician. If electrical hazards are not found to exist, work may proceed until changein conditions occurs. Should a change in conditions occur, work will be stopped and be

re-evaluated by a qualified electrician.

7.7.8 Fifty (50) amp cord caps and connector bodies for both 480v and 240v cordconnections used in temporary power systems are subject to failure under variousenvironmental conditions. Items such as moisture and dust penetrate the plugsterminals and contacts. Several considerations for protection against failure are asfollows:

A. Temporary systems can be hard-wired very cost effectively, eliminating plug-inconnections completely.

B. Cords may be custom made by a qualified person (in the field or in Pittsfield)where long runs are needed in order to eliminate plug-in connections.

C. Locate plug-in connections out of wet/moist areas.D. Keeping plug-in connections above floors or ground.E. Cover plug-in connections to allow water to run off without contacting the plugs.F. When plug-in connections must be used in a moist/wet environment,

manufacturers specified boots shall be installed with coupling rings, kept off wetsurfaces, and covered in a manner which will allow water to run off.

7.8 Electrical Surveys

7.8.1 The following should be surveyed routinely:A. Are electric panels completely and accurately labeled? Panels greater than 600

volts between phases shall be labeled High Voltage. Is each circuit accuratelylabeled?

B. Are electric panels clearly accessible and not blocked off?C. Are electrical boxes and panels properly located, supported, covered, and

openings sealed (no open holes)?

D. Are all light bulbs properly covered, guarded, and not broken? Metal guards mustbe grounded as required by National Electrical Code.

E. Are power cords routed up and out of travel ways?F. Are lugs and leads on electric welders properly insulated?G. Are Cianbro conex boxes correctly wired to the Cianbro standard?

(Available from Cianbro Equipment LLC.)H. Are buried cables properly flagged and signed?I. Have overhead power lines been marked for work that requires cranes to be in the

area?J. Are installations and modifications of electrical equipment being performed only by

licensed electricians and qualified persons?K. Does this site have electrically safe working conditions? Has a detailed activity

plan been developed? Has the Cianbro Energized Work Permit been filled out if

energized work must be done? Does this site have electricians qualified to doenergized work and certified by the Electrical Safety Committee?L. Are insulated tools and protective clothing and equipment available for work on

energized systems?M. Has protective equipment and clothing been inspected each day before use for

rips, tears, and damage?N. Do environmental conditions exist which create the conditions of working in or

around water? (Rain, snow, foggy conditions).O. Are all electrical receptacles, covers, and cord plugs intact and free from cracks?P. Old style Cianbro 240/480 volt distribution boxes should not be used in wet

environments unless covered or protected.


8/18


Q. New style Cianbro 240/480 volt distribution boxes must be used with the coversclosed at all times other than when installing or removing a cord. Extension cordsmust enter from under the cover and not through the side where they would besubject to damage by the cover.

7.9 Cianbro Arc Flash Protection Policy and Procedure

7.9.1 Cianbro team members and subcontractors shall perform work on electrical equipmentand circuits in a de-energized electrically safe state if at all possible. The tables ofNFPA 70E will be utilized, unless more accurate information is available from a system

specific Arc Flash Hazard Study, to determine Arc Flash Hazard/Risk Categories.Required personal protective equipment based on the Arc Flash Hazard/Risk Categoryfor that portion of the electrical system being worked on will be used. In addition, a livework permit including a hazard analysis is required to be completed with appropriatesignatures before any energized work is performed.

7.9.2 See SD1063 for Cianbro Energized Electrical Work Permit available onCianbro.net>Standard Operating Procedures SOP.

7.9.3 Flame Retardant Arc Rated Garments

A. Team members working on energized electrical equipment or circuits, or exposedto the hazards of an electrical arc flash, shall wear long sleeved flame retardantshirt, pants and/or outer garment designed to meet the requirements of the CianbroFlash Protection Matrix and NFPA 70E Table 130.7(C) (10) Protective Clothing andPersonal Protective Equipment (PPE) Matrix.

B. Proper Inspection, Use, and Care of FR Arc Rated Garments

Arc Rated clothing is intended to be used while team members are within the ArcFlash/Blast boundary, and not as a part of their daily working attire unlessotherwise specified.This clothing is to be purchased and maintained by Cianbro.Proper inspection and use is the responsibility of the user.

1. Inspection: Inspect the garment thoroughly for cleanliness Be sure there are no stains in garment as this could indicate the presence

of contaminants. Check for embedded foreign materials or foreign fibers. Inspect for excessive wear, or torn fabric before each use. Look for signs of repair such as stitches, patches etc. Check hood shield or face shield for damage and for excessive scratches

which could limit visibility. Do not use the garment if it does not pass inspection.

2. Use: Be sure to fasten all closures to eliminate the possibility of skin

exposure to an Arc event.

Be sure to use the correct Arc Rated garment for the task, as per NFPA70E requirements.

Take care not to snag or tear the fabric, as it cannot be repaired byconventional means. The integrity of the garment will be jeopardized byrepairs with inferior materials. If damaged remove it from service.

If garment is exposed to an arc event, remove it from service. Take care not to expose the garment to oils and grease which could be

absorbed into the fabric, causing it to burn if involved in an arc event.



13/18


3. Care and Cleaning: Follow manufacturers recommendations for proper care and cleaning. Be sure that the garment is washed after using. Hygiene can become an

issue when garments are shared by team members. Do not wash Arc Rated garments with other garments, as this can cause

foreign material to become embedded in the Arc Rated fabric. Do not use fabric softeners, or bleach while cleaning these garments. Store the garments in a clean container, and in a safe location. Be sure to protect face shields from scratches and other damage while

storing them.

7.9.4 When exposed to electrical hazards, team members shall not wear conductive articlessuch as key or watch chains, rings, wristbands, necklaces or other jewelry, or beltbuckles which could come into contact with live parts unless such articlesare coveredto prevent contact.

7.9.5 Team members whose job classification may require them to work on, or be exposedto, energized equipment or circuits and wear flame retardant garments shall beprepared to do so. The team member should not need to leave the job site to changeclothing in order to be in compliance. Flame retardant coveralls, suits, or othergarments, where warranted, shall be added over acceptable cotton or other naturalfiber work clothing at the job site.

7.9.6 Shock arc flash boundaries shall be delineated and marked by red barricade tape withappropriate information tags.

7.9.7 Flash Protection Matrix

A. The intent of the Flash Protection Matrix is to specify the minimum necessaryclothing and personal protective equipment to be worn while working on or nearenergized electrical equipment within the flash protection boundary. (per NFPA70E Table 130.7(C)(10) Protective Clothing and Personal Protective Equipment(PPE)

Notes:

1. See Table 130.7(C) (11). Arc rating for a garment or system of garments is expressed in cal/cm.2. If rubber insulating gloves with leather protectors are required by Table 130.7(C) (9), additional leather or arc-rated gloves arenot required. The combination of rubber insulating gloves with leather protectors satisfies the arc flash protection requirement.3. The FR shirt and pants used for Hazard/Risk Category 1 shall have a minimum arc rating of 4.4. Alternate is to use FR coveralls (minimum arc rating of 4) instead of FR shirt and FR pants.5. FR shirt and FR pants used for Hazard/Risk Category 2 shall have a minimum arc rating of 8.6. Alternate is to use FR coveralls (minimum arc rating of 8) instead of FR shirt and FR pants.7. A face shield with a minimum arc rating of 4 for Hazard/Risk Category 1 or a minimum arc rating of 8 for Hazard/Risk Category2, with wrap-around guarding to protect not only the face but also the forehead, ears and neck (or, alternatively, an arc-rated arc

flash suit hood), is required.8. An alternate is to use a total FR clothing and hood, which shall have a minimum arc rating of 25 for Hazard/Risk Category 3.9. The total clothing system consisting of FR shirt and pants and/or FR coveralls and/or arc flash coat and pants and hood shallhave a minimum arc rating of 40 for Hazard/Risk Category 4.10. Alternate is to use a face shield with a minimum arc rating of 8 and a balaclava (sock hood) with a minimum arc rating of 8and which covers the face, head and neck except for the eye and nose areas.

7.9.8 Fall Protection PPEA Fall protection PPE shall be Arc Flash/Flame resistant rated for the applicable

Hazard/Risk category.B. Specific information on products can be obtained from manufacturers such as

DBI/SALA-Fall Protection.

7.9.9 TestingA. Testing requires PPE and tools suitable for the hazard/risk category of the

equipment or circuits being tested.B. The proper test instrument must be chosen. Test instruments, equipment, and their

accessories will meet the requirements contained inANSI/ISA-61010-1-SafetyRequirements for Electrical Equipment for Measurement, Control, and LaboratoryUse Part 1 General Requirements, for rating and design requirements for voltagemeasurement and test instruments designed for use on electrical systems 1000volts and below.

C. For voltages over 50 volts, the test instrument shall be verified both before andafter an absence of voltage test is performed (Live, dead, live test). The person

7.10 Safety At Home

7.10.1 OSHA estimates that approximately 1000 electrocutions occur annually in the home.This is around three times the number of electrocutions in the workplace. One of thekey contributors is that people are generally complacent when it comes to usingelectrical appliances and tools at home. They feel they are in a Safe Zone and nevergive safety a thought. The fact that the use of electrical equipment has increased,combined with the frequent use of equipment by basically untrained people has donemuch to increase the risk. As construction workers we should strive to set a goodexample of safety in the home even though we may feel that it is a Safe Zone.

7.10.2 Following are several examples which could eliminate the possibility of electric shock orelectrocution. Use GFCI protection whenever we use electrical equipment outside, near

plumbing fixtures, in damp basements, near swimming pools, etc. Test each GFCI device based on the manufacturers recommendation at a

minimum. Understand which outlets are required by the National Electrical Code to be

GFCI protected. Take steps to ensure that electrical outlets are protected from contact by

children, and explain the hazards to them. Disconnect power when working on any portion of a circuit. Unplug cords when working on tools, equipment, or lights (even when changing a

light bulb). Avoid cutting trees that are within reach of a power line. Avoid using aluminum ladders or ariel lifts near power lines. Avoid working near service drops without involving the power company for advise

and protection. Determine the location of buried cables prior to digging with a machine or by

hand.
