1. Cable connectors (not of load-break type), fuses, terminal plugs or cable splice connectors may not be used, except in an emergency, to connect, disconnect or reverse in place of proper electrical circuits.

2. After a protective circuit is disconnected or opened, it may not be connected or closed until it has been determined that the equipment and circuit can be safely energized.

3. Overcurrent protectors of circuits or connected circuits may not be modified, even on a temporary basis, beyond the installation safety requirements.

4. Only Qualified workers may perform tests on electrical circuits or equipment.

5. Test equipment and all associated test leads, cables, power cords, probes and connectors shall be visually inspected for external damage before use. Any damage or defects shall be repaired before use or placed out of service.

6. Test equipment shall be rated to meet or exceed the voltage being tested and fit for the environment in which it is being used.

7. Where flammable or ignitable materials are stored, even occasionally, electrical equipment capable of igniting them may not be used unless measures are taken to prevent hazardous conditions from developing.

 Standard Operating Procedure

Electrical Pre-Work Procedure

Except in extreme cases, work on electrical equipment will be done with all electrical circuits in the work area de-energized by following the Lockout/Tagout procedure. When working on or near energized electrical circuits with less than 30 volts to ground, the equipment need not be de-energized if there will be no increased exposure to electrical burns or to explosion from electric arcs.

To prepare for work on electrical systems or components, the following procedure applies:

Caution:Treat all electrical circuits as “Live” until they have been Tagged and Locked Out and tested by the following procedure.

1. Obtain permission from supervisor to conduct work

2. Lockout and Tagout all sources of electrical power

3. Verify de-energized condition before any circuits or equipment are considered and worked as de-energized.

A. A qualified person shall operate the equipment operating controls or otherwise verify that the equipment cannot be restarted.

B. Verify proper operation of the Voltmeter at a live electrical source of the same rated voltage as the circuit to be worked.

C. Using the Voltmeter, check all exposed circuits phase to phase and phase to ground for evidence of voltage/current in the circuit.

D. Conduct work on the circuit only after determining that there is no voltage in any of the exposed circuits.

E. If voltage is detected in any exposed circuit, STOP, inform supervisor and determine source and procedure to eliminate voltage.

4. Conduct work

5. Close up all exposed circuits, boxes, controls, equipment.

6. Remove Lockout/Tagout

7. Obtain supervisor permission to energize circuits

 Standard Operating Procedure

Working on or Near Exposed Energized Circuits

In the rare situation when energized equipment (or working in near proximity to energized equipment) cannot be de-energized, the following work practices must be used to provide protection:

Caution: Unqualified Employees are prohibited from working on or near exposed energized circuits.

1. Obtain permission from Supervisor to work on or near energized electrical circuits

2. Lockout and Tagout all circuits possible

3. Treat all circuits as energized.

4. Remove all conductive clothing and jewelry (rings, watches, wrist/neck chains, metal buttons, metal writing instruments, etc.).

5. Use proper personal protective equipment, shields and/or barriers to provide effective electrical insulation from energized circuits. This may include electrically rated insulated gloves, aprons, rubber soled shoes, insulated shields, insulated tools, etc.

6. Provide adequate lighting. Do not enter areas with exposed energized parts unless illumination (lighting) is provided so that Employee may work safely. Do not reach around obstructions of view or lighting (blindly) into areas where exposed energized parts are located.

7. Employees entering a Confined Space with exposed energized parts, must use protective barriers, shields, or equipment or insulated materials rated at or above the present voltage to avoid contact.

8. Doors or other hinged panels shall be constructed and secured to prevent them from swinging into an Employee and causing contact with exposed energized parts.

9. Housekeeping in areas of exposed energized parts may not be completed in areas with close contact unless adequate safeguards (insulation equipment or barriers) are present. Conductive cleaning material (Steel Wool, Silicon Carbide, etc.) or liquids may not be used unless procedures (Lock and Tag Out, etc.) are in place and followed.

10. Station a safety observer outside work area. The sole function of this person is to quickly de-energize all sources of power or pull worker free from electrical work area with a non-conductive safety rope if contact is made with an energized electrical circuit.

11. A person qualified in CPR must be readily available to the scene.

 Standard Operating Procedure

Re-energizing Electrical Circuits after Work Completed

These requirements shall be met, in the order given, before circuits or equipment are reenergized, even temporarily.

1. A qualified worker shall conduct tests and visual inspections, as necessary, to verify that all tools, electrical jumpers, shorts, grounds, and other such devices have been removed, so that the circuits and equipment can be safely energized.

2. Warn employees exposed to the hazards associated with reenergizing the circuit or equipment to stay clear of circuits and equipment.

3. Remove each lock and tag. They shall be removed by the employee who applied it or under his or her direct supervision. However, if this employee is absent from the workplace, then the lock or tag may be removed by a qualified supervisor designated to perform this task provided that:

A. The supervisor ensures that the employee who applied the lock or tag is not available at the workplace, and

B. The supervisor ensures that the employee is aware that the lock or tag has been removed before he or she resumes work at that workplace.

4. Conduct a visual determination that all employees are clear of the circuits and equipment.


 Personal Protective Equipment

Employees working in areas where the potential contact with exposed electrical sources are present and likely, will be provided and shall use Personal Protective Equipment (PPE). The following rules apply to the use and care of PPEs:

1. PPEs shall be used where contact with exposed electrical sources are present and likely.

2. PPEs shall be designed for the work being performed and environment in which it is used.

3. PPEs shall be visually inspected and/or tested before use. Any defects or damage shall be replaced, repaired or discarded.

4. In cases where the insulating capabilities of the PPEs may be damaged during the work, a protective outer cover, such as leather, must be used.

2. PEE shall be visually inspected for damage, wear, cracked or spilt outer jackets or insulation, etc., before use or before each shift. PEE that remain connected once put in place need not be inspected until relocated. Any defects; such as cracked or split outer jackets or insulation must be repaired, replaced or placed out of service.

3. Always check the compatibility of cord sets and receptacles for proper use.

4. Ground type cord sets may only be used with ground type receptacles when used with equipment requiring a ground type conductor.

5. Attachment plugs and receptacle may not be altered or connected in a way that would prevent the proper continuity of the equipment grounding conductor. Adapters may not be used if they interrupt the continuity of the grounding conductor.

6. Only portable electrical equipment that is double insulated or designed for use in areas that are wet or likely to contact conductive liquids may be used.

7. Employees that are wet or have wet hands may not handle PEEs (plug-in, un-plug, etc.). Personal protective equipment must be used when handling PEEs that are wet or covered with a conductive liquid.

8. Locking-type connectors shall be properly secured after connection to a power source.


Engineering Controls

  • All electrical distribution panels, breakers, disconnects, switches, junction boxes shall be completely enclosed
  • Water tight enclosure shall be used where there is possibility of moisture entry either from operations or weather exposure
  • Electrical distribution areas will be guarded against accidental damage by locating in specifically designed rooms, use of substantial guard posts and rails and other structural means
  • A clear approach and 3 foot side clearance shall be maintained for all distribution panels.
  • All conduit shall be fully supported throughout its length. Non-electrical attachments to conduit is prohibited.
  • All non-rigid cords shall be provided strain relief where necessary.

Administrative Controls

  • Only trained and authorized employees may conduct repairs to electrical equipment.
  • Contractors performing electrical work must hold a license for the rated work
  • Areas under new installation or repair will be sufficiently guarded with physical barriers and warning signs to prevent unauthorized entry
  • Access to electrical distribution rooms is limited to those employees who have a need to enter
  • All electrical control devices shall be properly labeled
  • Work on energized circuits is prohibited unless specifically authorized by senior facility management
  • All qualified workers will follow established electrical safety procedures and precautions

Protective Equipment

  • Qualified workers will wear electrically rated safety shoed/boots.
  • All tools used for electrical work shall be properly insulated
  • Electrical rated gloves shall be available for work on electrical equipment
  • Electrically rated matting will be installed in front of all distribution panels in electric utility rooms

Electrical Equipment


Electrical equipment shall be free from recognized hazards that are likely to cause death or serious physical harm to employees. Safety of equipment shall be determined using the following considerations:

  • Suitability for installation and use in conformity with the provisions of this subpart. Suitability of equipment for an identified purpose may be evidenced by listing or labeling for that identified purpose.
  • Mechanical strength and durability, including, for parts designed to enclose and protect other equipment, the adequacy of the protection thus provided.
  • Electrical insulation.
  • Heating effects under conditions of use.
  • Arcing effects.
  • Classification by type, size, voltage, current capacity, and specific use.
  • Other factors which contribute to the practical safeguarding of employees using or likely to come in contact with the equipment.

Identification of Disconnecting Means and Circuits

Each disconnecting means for motors and appliances shall be legibly marked to indicate its purpose. Each service, feeder, and branch circuit, at its disconnecting means or overcurrent device, shall be legibly marked to indicate its purpose. These markings shall be of sufficient durability to withstand the environment involved.

A disconnecting means is a switch that is used to disconnect the conductors of a circuit from the source of electric current. Disconnect switches are important because they enable a circuit to be opened, stopping the flow of electricity, and thus can effectively protect workers and equipment.

Each disconnect switch or overcurrent device required for a service, feeder, or branch circuit must be clearly labeled to indicate the circuit’s function, and the label or marking should be located at the point where the circuit originates. For example, on a panel that controls several motors or on a motor control center, each disconnect must be clearly marked to indicate the motor to which each circuit is connected. In the figure below, the Number 2 circuit breaker in the panel box supplies current only to disconnect Number 2, which in turn controls the current to motor Number 2. This current to motor Number 2 can be shut off by the Number 2 circuit breaker or the Number 2 disconnect.

All labels and markings must be durable enough to withstand weather, chemicals, heat, corrosion, or any other environment to which they may be exposed.
