This section has been reviewed and updated as needed: March 2014
The purpose of this policy is to provide minimum guidelines for safety-related work practices to ensure a safe and healthful work environment is provided for UNC-CH employees who may be exposed to electrical circuits or electrical hazards.
The University has utilized OSHA Standards 1910.331 through .335 and the NFPA 70E Standard for Electrical Safety in the Workplace in the development of this requirement. It applies to state employees both qualified (those familiar with the construction and operation of electrical equipment, the hazards involved and who have training in avoiding the electrical hazards of working on or near energized parts) and unqualified (those with little or no such training) who work on, near or with electrical circuits, except where qualified employees are excluded.
Environment, Health and Safety
EHS is responsible for reviewing hazards associated with electrical safety during annual shop inspections. EHS is responsible for reviewing and updating the Electrical Safety Policy. EHS will assist departments in implementing the provisions of this program and developing task specific training and procedures. EHS and Supervisors also work jointly in the development of Job Safety Analysis (JSA) to document first-time procedures.
Supervisor and Employee
Supervisors are responsible for implementing the Electrical Safety Program within their areas and ensure employees comply with the program. Supervisors develop and maintain a list of all qualified employees in their areas. They must ensure employees are provided with and use appropriate protective equipment. Supervisor led training is required upon employment for employees who may be exposed to electrical circuits or electrical hazards. An excellent means of conducting this training is to develop a JSA that covers the pertinent information on how to properly and safely use these types of tools and equipment with machine safeguards. The following link provides further information on how to develop a JSA: UNC-CH EHS Job Safety Analysis.
Employees must perform electrical work in accordance with this program. They must conduct a visual inspection of PPE, equipment and tools prior to each use to ensure good working condition. Employees must notify their supervisor if PPE, equipment or tools are found to be defective. They must also keep unqualified people outside of the qualified worker boundary.
Safe work practices shall be employed to prevent electric shock or other injuries resulting from either direct or indirect contact with electrically energized equipment or circuits. The specific safety related work practices shall be consistent with the nature, extent and voltage of the associated electrical hazards. Campus departments must develop specific procedures to address work practices specific to their work environments.
Before employees may be exposed to work on or near live parts or circuits they must be placed into an electrically safe work condition (i.e., de-energized) unless the employer can demonstrate that de-energizing introduces additional or increased hazards or is unfeasible due to equipment design or operational limitations. Live 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 to explosion due to electric arcs. An electrical hazard is considered to be present until an electrically safe work condition exists.
- Conductors and parts of electric equipment that have been de-energized but have not been properly locked out or tagged out shall be treated as energized.
- Lockout and Tagging: While any employee is exposed to contact with parts of fixed electric equipment or circuits which have been de-energized, the circuits energizing the parts shall be locked out or tagged out or both (see the Lockout/Tagout Requirements section of this Manual).
- Safe procedures for de-energizing circuits and equipment shall be determined before circuits or equipment are de-energized.
- All possible energy sources must be identified for the involved circuits and equipment. Check applicable up-to-date drawings, diagrams, and identification tags. Control circuit devices, such as push buttons, selector switches, and interlocks, may not be used as the sole means for de-energizing circuits or equipment. Interlocks for electric equipment may not be used as a substitute for lockout and tagging procedures.
- Stored electrical energy which might endanger personnel is released such as discharging capacitors and short-circuiting and grounding high capacitance elements, if the stored electrical energy might endanger personnel. If the capacitors or associated equipment are handled in meeting this requirement they are treated as energized.
- Stored non-electrical energy (hydraulic, pneumatic, etc.) in devices that could re-energize electric circuit parts shall be blocked or relieved to the extent that the circuit parts cannot be accidentally energized by the device (see the Lockout/Tagout Requirements section of this Manual).
- A qualified person operates the equipment, operating controls or otherwise verifies that the equipment cannot be restarted.
- A qualified person uses test equipment to test the circuit elements and electrical parts of equipment to which employees will be exposed and verifies that the circuit elements and equipment parts are de-energized. The test shall also determine if any energized condition exists as a result of inadvertently induced voltage or unrelated voltage backfeed even though specific parts of the circuit have been de-energized and presumed to be safe.
- A three-step testing procedure should be used for voltage: 1) Test a known source to verify the tester is operating properly; 2) Use tester to confirm that the equipment has zero voltage; and 3) Test a known source again to verify the tester is operating properly.
- A qualified person conducts test and visual inspections, as necessary, to verify that all tools, electrical jumpers, shorts, grounds and other such devices have been removed, so that circuits and equipment can be safely energized.
- Employees exposed to the hazards associated with re-energizing the circuit or equipment shall be warned to stay clear of circuits and equipment.
- Each lock and tag shall be removed by the employee who applied it or under his or her direct supervision. However, if the person is absent from the workplace, then the lock or tag may be removed by a qualified person designated to perform this task provided that the supervisor ensures the person who applied the lock or tag is not available at the workplace, ensures that the employee is aware that his or her tag has been removed before he or she resumes work at that workplace, and a visual determination is made to ensure that all people are clear of the circuits and equipment.
The Electrical Safety Program is based on the principle of avoiding energized work unless it is absolutely necessary. All other possibilities for establishing an electrically safe work condition must be exhausted before working on or near exposed energized parts. If exposed live parts are not de-energized (i.e., for reasons of increased or additional hazards or unfeasibility), other safety related work practices shall be used to protect employees who may be exposed to the electrical hazards involved. Such work practices shall protect employees against contact with energized circuit parts directly with any part of their body or through some other conductive object. The work practices that are used shall be suitable for the conditions under which the work is to be performed and for the voltage level of the exposed electric conductors or circuit parts.
- De-energizing creates an additional hazard or increased risk. Examples of additional hazard or increased risk include, but are not limited to, interruption of life-support equipment, deactivation of emergency alarm systems, loss of power will result in an environmental spill, or shutdown of a hazardous location’s ventilation system.
- The task to be performed is infeasible in a de-energized state due to equipment design or operational limitations. If it is not possible to de-energize the exposed energized parts by performing the work at a different time, then the work task is infeasible to perform in an electrically safe work condition. Examples of infeasibility include, but are not limited to, performing diagnostics and testing to troubleshoot electrical circuits that can only be performed with the circuit energized or working on circuits that form an integral part of a continuous process that would otherwise need to be completely shut down in order to permit work on one circuit or piece of equipment.
- Exposed energized electrical parts that operate at less than 50 volts where it is determined that there will be no increased exposure to electrical burns or to explosion due to electric arcs. If voltage is less than 50 volts, only the shock hazard is not present. Other hazards such as a thermal or pressure hazard may be present in the event of a short-circuit condition (e.g. batteries).
The energized electrical work permit shall include, but not limited, to the following items:
- Description of the circuit and equipment to be worked on and location
- Justification for why the work must be performed energized
- Description of the safe work practices to be employed
- Results of shock hazard analysis
- Limited approach boundary
- Restricted approach boundary
- Prohibited approach boundary
- Necessary personal protective equipment
- Results of arc flash hazard analysis
- Available incident energy or hazard/risk category
- Necessary personal protective equipment
- Arc flash boundary
- Means to restrict access of unqualified persons from the work area
- Evidence of completion of a job briefing, including any job-specific hazards
- Energized work approval signatures
Exception: Work related to testing, troubleshooting, and voltage measuring may be completed without a permit provided appropriate safe work practices and PPE are used. In general, these tasks require equipment or circuit to be energized. Employees conducting these tasks should be specifically chosen based on their knowledge and skill.
- Limited approach boundary: The closest approach distance for an unqualified employee unless protective measures are used. A qualified worker must escort the unqualified worker at all times while working inside this boundary.
- Restricted approach boundary: The closest approach distance for a qualified employee unless additional protective measures are used.
- Prohibited approach boundary: Boundary that must not be crossed unless energized safe work practices are used such as wearing appropriate PPE.
- At least one of the following:
- Available incident energy and the corresponding working distance
- Minimum arc rating of clothing
- Required level of PPE
- Highest Hazard/Risk Category (HRC) for the equipment
- Nominal system voltage
- Arc flash boundary
The method of calculating and data to support the information for the label shall be documented.
Other Precautions for Personnel Activities
- Overhead Lines: When work is to be performed near overhead lines, the lines shall be de-energized and grounded or other protective measures shall be provided before work is started. If the lines are to be de-energized, arrangements shall be made with the electric utility company, person or organization that operates or controls the electric circuits involved to de-energize and ground them. If protective measures, such as guarding, isolating, or insulating, are to be provided, these precautions shall prevent employees from contacting such lines directly with any part of their body or indirectly through conductive materials, tools, or equipment. Only qualified persons of the electric utility, power transmission and distribution organizations are allowed to install insulating devices on overhead power transmission and distribution lines.
- Illumination: Employees shall not enter spaces containing exposed energized parts, unless illumination is provided that enables the employees to perform the work safely. Employees are not to perform tasks on or near exposed energized parts where there is a lack of illumination or an obstruction which precludes observation of work to be performed. Install temporary lighting for areas with low illumination. Additional lighting may be required due to darkness of a face shield.
- Blind Reaching: Employees shall not reach blindly into areas that might contain exposed live parts.
- Confined or Enclosed Work Spaces: Prior to entry employees must be trained in the confined space entry requirements. For employees working in confined or enclosed spaces such as manholes or vaults that contain exposed energized parts, the department shall provide and the employee shall use protective shields, protective barriers, or insulating materials as necessary to avoid inadvertent contact with these parts. Doors, hinged panels and the like shall be secured to prevent their swinging into an employee and causing the employee to contact exposed energized parts.
- Conductive Materials and Equipment: Conductive materials or equipment that is in contact with any part of an employee’s body shall be handled in a manner that will prevent the employee from contacting exposed energized conductors or circuit parts.
- If an employee must handle long dimensional conductive objects (such as ducts and pipes) in areas with exposed live parts, the employer shall institute work practices (such as the use of insulation, guarding, and material handling techniques) which will minimize the hazard.
- Portable Ladders: All portable ladders shall be non conductive if they are used where the employee or the ladder could contact exposed energized parts. (See Stairways and Ladder section of this Manual for additional requirements on the use, maintenance and storage of ladders.)
- Conductive Apparel: Employees are not allowed to wear conductive articles of jewelry and clothing such as watch bands, bracelets, rings, key chains, necklaces, metalized aprons, cloth with conductive thread, or metal headgear if they might contact exposed energized parts. However, such articles may be worn if rendered non conductive by covering, wrapping, or other insulating means.
- Housekeeping Duties: Housekeeping duties shall not be performed close enough for possible contact with live parts, unless adequate safeguards such as insulating equipment or barriers are provided.
- Electrically conductive cleaning materials including conductive solids such as steel wool, metalized cloth, and silicon carbide, as well as conductive liquid solutions shall not be used near energized parts unless procedures are followed which prevent electrical contact.
- Interlocks: Only qualified persons are allowed to defeat an electrical safety interlock following the above specified procedures for working on or near exposed energized parts, and then only temporarily while they are working on the equipment. Also, the interlock system will be returned to its operable condition when this work is completed and verified to be operational.
- Occasional use of flammable or ignitable materials: Where flammable or ignitable materials are present only occasionally, electric equipment capable of igniting them shall not be used unless measures are taken to prevent hazardous conditions from developing. Materials include, but are not limited to: flammable gases, vapors or liquids; combustible dust; and ignitable fibers or filings.
- Alerting Techniques: The following alerting techniques are used to warn and protect employees from electrical shock hazards, burns, or failure of electric equipment parts.
- Safety Signs and Tags: Safety signs, safety symbols, or accident prevention tags are to be used where necessary to warn employees about electrical hazards which may endanger them. Such signs and tags shall meet the requirements of ANSI Z535, Series of Standards for Safety Signs and Tags.
- Barricades: are used in conjunction with safety signs where necessary to prevent or limit employee access to work areas exposing employees to uninsulated energized conductors or circuit parts. Conductive barricades may not be used where they might cause an electrical contact hazard. Barricades shall be placed no closer than the limited approach boundary.
- Attendants: If signs and barricades do not provide sufficient warning from hazards, an attendant is to be stationed to warn and protect employees.
Before starting each work task involving potential exposure to an electrical hazard, supervisors must discuss all hazards associated with the task with all involved employees. At a minimum, the discussion should include the following subjects:
- Electrical hazards associated with the work task
- Procedures that must be followed when executing the work task
- Any special precautions that are required by the working conditions
- Where and how to remove the energy source
- Emergency response and emergency communications
- Required PPE
- Other work in the immediate physical area
- Other work associated with the same electrical circuits or equipment
Additional job briefings shall be held if changes that might affect the safety of employees occur during the course of the work.
If the work task is a repetitive task that is performed several times during the day, a single job briefing held before the employee performs the task for the first time is satisfactory. A brief discussion shall be satisfactory if the work involved is routine and if the employee is qualified for the task. A more extensive discussion shall be conducted if either of the following apply:
- The work is complicated or particularly hazardous.
- The employee cannot be expected to recognize and avoid the hazards involved in the job.
Use of Equipment
Portable electrical equipment applies to the use of cord-and-plug connected equipment and flexible cord sets (extension cords).
Flexible cords are not to be fastened with staples or otherwise hung in such a fashion as to damage the outer jacket or insulation.
When defects or evidence of damage which might expose employees to injury are detected, the defective or damaged item shall be removed from service and no person shall use it until it is repaired and tested to ensure it is safe for use.
- Flexible cords used with grounding-type equipment shall contain an equipment grounding conductor. Other protective measures include double insulation or ground-fault circuit-interrupters (GFCIs).
- Employees shall be provided with GFCI protection where required by applicable state, federal, or local codes and standards.
- GFCI protection shall be provided when an employee is outdoors and operating or using cord- and plug-connected equipment supplied by 125-volt, 15-, 20-, or 30-amp circuits. For equipment supplied by other voltages and amps an assured equipment grounding conductor program shall be implemented to verify the integrity of the grounding conductor of cord sets and cord-and-plug connected equipment.
- Attachment plugs and receptacles may not be connected or altered in any manner which would prevent proper continuity of the equipment grounding conductor at the point where plugs are attached to receptacles. Additionally, these devices may not be altered to allow the grounding pole to be inserted into current connector slots. Clipping the grounding prong from an electrical plug is prohibited.
- Adapters which interrupt the continuity of the equipment grounding connection may not be used.
If the connection could provide a conducting path to employees hands, (if, for example, a cord connector is wet from being immersed in water) the energized plug and receptacle connections must be handled only with insulating protective equipment.
Locking-type connectors shall be properly locked into connector.
Electric Power and Lighting Circuits
Routine Opening and Closing of Circuits
Load rated switches, circuit breakers, or other devices specifically designed as disconnecting means shall be used for the opening, reversing, or closing of circuits under load conditions.
Cable connectors not of the load-break type, fuses, terminal lugs, and cable splice connections may not be used for opening, reversing, or closing circuits under load conditions except in an emergency.
Reclosing Circuits after Protective Device Operation
After a circuit is de-energized by a circuit protective device, the circuit may not be manually re-energized until it has been determined that the equipment and circuit can be safely energized.
The repetitive manual reclosing of circuit breakers or re-energizing circuits through replaced fuses is prohibited.
When it can be determined from the design of the circuit and overcurrent devices involved that the automatic operation of a device was caused by an overload rather than a fault condition, no examination of the circuit or connected equipment is needed before the circuit is re-energized.
Overcurrent Protection Modification
Overcurrent protection of circuits and conductors may not be modified, even on a temporary basis.
Test Equipment and Instruments
Only qualified persons may perform testing, troubleshooting, and voltage measuring within the limited approach boundary of energized electrical conductors or circuit parts operating at 50 volts or more or where an electrical hazard exists. Employees must be trained to understand that when they are performing testing, they are exposed to shock and electrocution hazards. Each qualified person must be trained to understand how to operate every meter that he or she could be expected to use and to interpret its readings.
When test instruments are used for testing the absence of voltage on conductors or circuit parts operating at 50 volts or more, the operation of the test instrument shall be verified before and after the test is performed. An indication of zero volts might mean that no voltage is present when the test is performed or that the instrument has failed.
Test instruments and equipment including all associated test leads, cables, power cords, probes and connectors shall be visually inspected for external defects and damage before the equipment is used. If there is a defect or evidence of damage that might expose an employee to injury, the defective or damaged item shall be removed from service, tagged out of service and no employee may use it until repairs and tests necessary to render the equipment safe have been made.
Rating of Equipment
Test instruments, equipment, and their accessories shall be rated for the circuits and equipment to which they will be connected and designed for the environment in which they will be used.
