4.0 DEFINITIONS
4.1 Arc Rating – The value attributed to materials that describe their performance to exposure to an electrical arc discharge. The arc rating is expressed in cal/cm2 and is derived from the determined value of the arc thermal performance value (ATPV) or energy of breakdown threshold (EBT) (should a material system exhibit a breakdown response below the ATPV value). Arc rating is reported as either ATPV or EBT, which is the lower value.
4.2 Boundary, Limited Approach – An approach limit at a distance from an exposed energized electrical conductor or circuit part within which a shock hazard exists.
4.2.1 The limited approach boundary is a shock protection boundary that is not related to arc flash or incident energy.
4.2.2 This boundary defines the approach limit for unqualified employees and is intended to eliminate the risk of contact with an exposed energized electrical conductor or circuit part.
4.3 Boundary, Restricted Approach – An approach limit at a distance from an exposed electrical conductor or circuit part within which there is an increased likelihood of electric shock, due to electrical arc over combined with inadvertent movement, for personnel working in close proximity to the energized electrical conductor or circuit part.
4.3.1 This shock protection boundary is the approach limit for qualified employees.
4.3.2 A qualified employee required to cross the restricted approach boundary must be protected from unexpected contact with the conductor or circuit part.
4.4 De-energized – Free from any electric connection to a source of potential difference and from electric charge.
4.5 Energized – Electrically connected to, or is, a source of voltage.
4.6 Exposed Worker – Person performing an electrical task.
4.7 Equi-potential Zone – Temporary protective grounding devices that have been placed at specific locations and arranged in a manner to provide a work zone that prevents each employee from being exposed to hazardous differences in electrical potential (voltage) in the event that de-energized circuits or equipment are inadvertently energized.
4.8 Exposed Energized Parts – Electrical equipment and circuits which are not guarded or isolated, that are electrically connected to a source of potential difference (voltage), or electrically charged so as to have a potential significantly different from earth.
4.9 FRC – Fire Retardant Clothing approved by Nitro Construction Services, LLC.
4.10 Full Electrical PPE – Full Electrical PPE includes: FRC, safety glasses, flash suit with hood and face protection, hearing protection, and insulated gloves with leather protectors that are properly rated for voltage present.
Note: For switching activities where no shock hazard exists, Nomex/flame retardant gloves may be used in place of insulated gloves.
4.11 Guarded – Covered, shielded, fenced, enclosed, or protected by suitable covers, casings, barriers, rails, screens, mats, or platforms to remove the likelihood of approach or contact by persons or objects to a point of danger.
4.12 Manhole – A subsurface enclosure that personnel may enter and which is used for the purpose of installing, operating, and maintaining electrical cable.
4.13 Minimum Approach Distance – The closest distance a person is permitted to approach exposed energized parts.
4.14 Overload – Operation of equipment in excess of the normal full-load rating, or of a conductor in excess of rated ampacity, which when it persists for a sufficient length of time, would cause damage or dangerous overheating. A fault, such as a short circuit or ground fault, is NOT an overload.
4.15 Portable Electric Equipment – Cord and plug-connected equipment including flexible cord sets (extension cords).
4.16 Qualified Person – A person who is trained and knowledgeable in the construction and operation of electrical equipment and who has been trained to recognize the hazards associated with electrical equipment. It is very possible for an individual to be considered “qualified” for certain electrical equipment in the workplace, but “unqualified” for other equipment.
4.17 Risk Assessment – An overall process that identifies hazards, estimates the potential severity of injury or damage to health, estimates the likelihood of occurrence of injury or damage to health and determines if protective measures are required.
4.18 Safety Glasses – ANSI-approved (Z-87) safety glasses with side shields.
4.19 Unqualified Person – A person who has little or no training to work on, or near electrical equipment and has limited or no knowledge of the hazards associated with electrical equipment.
4.20 Working On (energized electrical conductors or circuit parts) – Coming in contact with energized electrical conductors or circuit parts with the hands, feet, or other body parts, with tools, probes, or with test equipment, regardless of personal protective equipment a person is wearing. There are two categories of “working on”: Diagnostic (testing) is taking readings or measurements of electrical equipment with approved test equipment that does not require making any physical change to the equipment; repair is any physical alteration of electrical equipment (such as making or tightening connections, removing or replacing components, etc.).

6.0 PROCEDURE
6.1 General Work Practices
6.1.1 All energized parts to which persons may be exposed must be de-energized before any person works on or near unless it can be demonstrated that de-energizing introduces “increased or additional hazards” or is “not feasible” due to equipment design or operational limits.
6.1.1.1 Examples of “increased or additional hazard” may include, but not necessarily be limited to the following:
6.1.1.1.1 Deactivation of emergency alarm systems.
6.1.1.1.2 Shutdown of hazardous location ventilation equipment.
6.1.1.1.3 Removal of illumination for an area.
6.1.1.2 Examples of “not feasible” may include, but not necessarily be limited to the following:
6.1.1.2.1 Testing of electric circuits that can only be performed with the circuit energized.
6.1.1.2.2 Work on circuits that are essential to a continuous industrial process.
6.1.1.3 Energized parts that operate at less than 50 volts to ground need not be de-energized if there will be no increased exposure to electrical burns or explosion due to electrical arcs.
6.1.2 Conductors and parts of electric equipment that have been de-energized but have not been locked out or tagged in accordance with the Nitro Construction Services Lockout/Tagout Policy or the adopted policy of a particular project, or client, and the specific requirements in this procedure, will be treated as energized.
6.2 Working On or Near Exposed De-energized Parts (De-energizing/Re-energizing)
6.2.1 De-energizing Equipment
6.2.1.1 Procedures for safely de-energizing circuits and equipment must be determined before equipment can be de-energized.
6.2.1.2 All energy sources for the equipment to be worked on must be disconnected. Push buttons, selector switches, interlocks, and other control circuit devices may not be used as the sole means for disconnection circuits or equipment.
6.2.1.3 Interlocks for electrical equipment may not be used as a substitute for a lockout device or tag.
6.2.1.4 All capacitors, other high capacitance elements, and any line to which capacitors are connected will be discharged, short-circuited, and grounded if the stored electrical energy might endanger personnel. Such items will be treated as energized while performing this task.
6.2.1.5 All stored mechanical energy in devices that could re-energize electric circuit parts will be blocked or relieved to prevent accidentally energizing by the device.
6.2.1.6 A lock and tag will be placed on each energy source used to de-energize circuits and equipment on which work is to be performed. De-energization must be performed in accordance with the Nitro Construction Services Lockout/Tagout Procedure or the adopted policy of a particular project or client. A lock or tag may only be used independently under the following conditions:
6.2.1.6.1 If a lock cannot be applied, a tag used without a lock is only permitted when supplemented by at least one additional safety measure that provides a level of safety equivalent to that obtained using a lock. Examples of additional safety measures may include, but not necessarily be limited to the following:
6.2.1.6.1.1 Removal of an isolation circuit element.
6.2.1.6.1.2 Blocking of a controlling switch.
6.2.1.6.1.3 Opening of an extra disconnection device.
6.2.1.6.2 A lock may never be used without a tag.
6.2.1.7 All complex lockout/tag out procedures shall require a written plan of execution that identifies the person in charge. Each complex lockout/tag must be under the direct control of a single person who is identified in the written plan.
6.2.1.7.1 A complex lockout/tag out plan shall be permitted where one or more of the following exist:
6.2.1.7.1.1 Multiple energy sources

6.2.1.9 Utilizing the proper personal protective equipment, a qualified person must use approved test equipment to test the circuit elements and electrical parts of equipment to which employees will be expose; to verify that the circuit elements and equipment parts are de-energized. The test will determine if any energized condition exists because of induced voltage or voltage back feed. The following steps must be used to ensure that electrical equipment has been safely and effectively de-energized:
6.2.1.9.1 The approved test equipment must be visually inspected for proper operation and insulation integrity.
6.2.1.9.2 The qualified person must check the approved test equipment on a known energized source or an approved “test set” in order to verify the proper operation of the test equipment.
6.2.1.9.3 Using the approved test equipment, check that the electrical equipment or circuits in question have been de-energized.
6.2.1.9.4 The approved test equipment must be re-check on a known energized source or an approved “test set” immediately after the test to reconfirm the proper operation of the test equipment.
6.2.1.10 The following shall be required for grounding equipment:
6.2.1.10.1 Temporary protective grounds shall be placed at such locations and arranged in such a manner as to prevent each employee from being exposed to hazardous differences in electrical potential.
6.2.1.10.2 Temporary protective grounds shall be capable of conducting the maximum fault current that could flow at the point of grounding for the time necessary to clear the fault.
6.2.1.10.3 Temporary protective grounds shall have an impedance low enough to cause immediate operation of protective devices in case of accidental energizing of the electric conductors or circuit parts.
6.2.1.10.4 Until the line or equipment has been effectively grounded, all exposed circuits and parts will be treated as energized. Thus, the appropriate work practices, PPE, and tools must be utilized prior to and during the installation of the protective grounding equipment.
6.2.1.10.5 Prior to installing grounds, equipment must be tested to ensure the voltage is absent unless a previously installed ground is already in place.
6.2.1.10.6 Whenever possible, live-line tools or hot sticks must be used to attaché or remove ground connections from lines and equipment unless the design of the equipment does not permit the use of such tools or equipment.
6.2.1.10.7 Order of connection – When attaching a ground to a line or piece of equipment, the ground-end connection must be attached first.
6.2.1.10.8 Order of removal – When removing grounds, first remove the protective grounding equipment from the line or equipment before removing the ground-end connection.
6.2.1.10.9 Grounds may be temporarily removed for testing; however, the equipment must be treated as energized while grounds are not attached.
6.2.1.10.10 If grounding is demonstrated to be impractical or the conditions resulting from the installation of grounding equipment would present greater hazards than working without grounds, the equipment may be treated as de-energized if all of the following conditions are met:
6.2.1.10.10.1 The equipment has been locked out in accordance with the Nitro Construction Services Lockout/Tagout Procedure or the adopted policy of a project or client.
