UC Irvine – High Voltage Electrical Safety Program Appendix A Hazard Assessment and Standard Operating Procedures (SOP) for High Voltage Activities UC Irvine shall develop and employ work practices and procedures to minimize work involving energized electrical systems and components. In the event that this increases the hazard(s) or is infeasible, UC Irvine shall utilize work practices and procedures to prevent electrical shock or other injuries resulting from either direct or indirect electrical contacts. The best known method for preventing accidents, injuries, and other incidents during energized electrical work is to pre-plan the corresponding work and use the appropriate work procedures, tools, guards, personal protective equipment (PPE), and other controls to minimize the potential for contact with energized electrical circuits. UC Irvine will develop and implement a written Hazard Assessment and SOP for all High Voltage activities. The Hazard Assessment and SOP should be written and implemented when a project possesses an exposure or a non-routine task possesses a hazard. Qualified High Voltage Electrical Workers must assess the tasks to be performed and note whether the work can be performed with the equipment in the de-energized state, as described below. The equipment manual, as well as personnel who are experienced with the equipment, shall be consulted for assistance in making these determinations. When work on equipment must be performed while energized, follow the procedures for energized electrical work as described in this program. When work involves cords and plug-in equipment, follow the cord and plug-in procedures as described below. Identity of High Voltage space: ______________________________________________ Areas to assess in high voltage activities Check box to indicate if areas have been assessed Hazards identified in high voltage activities (e.g. physical hazards) Illumination - Auxiliary lighting must be provided where fixed lighting is not adequate to provide appropriate light levels. Illumination Employees must not reach into any areas that may contain energized parts without adequate lighting. 1 Check box to indicate if hazards are controlled Indicate how hazards are controlled Check box if work unit specific training is required UC Irvine – High Voltage Electrical Safety Program Areas to assess in high voltage activities Check box to indicate if areas have been assessed Hazards identified in high voltage activities (e.g. physical hazards) Housekeeping Individuals performing electrical work must use good housekeeping practices. Housekeeping - Work areas should be kept clean and free of debris to allow for the work to be completed safely. Housekeeping Housekeeping duties should not be performed when energized parts present an electrical contact hazard, unless adequate safeguards such as barriers and insulating equipment are provided. Housekeeping Electrically conductive cleaning materials (e.g., steel wool, metallized cloth, silicon carbide, conductive liquid solutions such as ammonia, etc.) should not be used in close proximity to energized equipment unless procedures are followed that will prevent contact with the energized equipment. Conductive Equipment and Apparel - Personnel 2 Check box to indicate if hazards are controlled Indicate how hazards are controlled Check box if work unit specific training is required UC Irvine – High Voltage Electrical Safety Program Areas to assess in high voltage activities Check box to indicate if areas have been assessed Hazards identified in high voltage activities (e.g. physical hazards) performing electrical work shall not wear conductive apparel such as: watches, rings, key chains, necklaces, metal headgear (including glasses), and other metal accessories unless rendered non-conductive by insulating means. Conductive Equipment and Apparel – All necessary protective devices such as insulated and rated gloves, safety glasses (nonmetallic and non conductive), hoods, and rubber blankets must be used. Shoes or boots must be nonconductive. See Appendix C. Conductive Equipment and Apparel - Conductive measuring tapes, fish tapes, ladders or tools shall not be permitted when working on or near electrical equipment. Conductive Equipment and Apparel – A careful inspection shall be made of all equipment used for handling or testing energized lines or equipment. 3 Check box to indicate if hazards are controlled Indicate how hazards are controlled Check box if work unit specific training is required UC Irvine – High Voltage Electrical Safety Program Areas to assess in high voltage activities Check box to indicate if areas have been assessed Hazards identified in high voltage activities (e.g. physical hazards) Conductive Equipment and Apparel – Inspect cables, connectors, and any other supplies for damage. Do not use if they are damaged. Conductive Equipment and Apparel – Protective equipment must be stored in a dry location. Protect equipment from heat, light, and oily environments. Signs and Labels Safety signs, tags, labels, and barricades must be used during electrical work to warn persons of electrical shock and burn hazards. Signs and Labels - If safety signs, tags, and barricades do not provide sufficient warning about electrical hazards (e.g., an electrical interlock removed from an AC distribution box with voltages above 600 volts), an attendant shall be stationed to warn employees and restrict access. Signs and Labels Guarding to protect personnel who may be in the general work area, 4 Check box to indicate if hazards are controlled Indicate how hazards are controlled Check box if work unit specific training is required UC Irvine – High Voltage Electrical Safety Program Areas to assess in high voltage activities Check box to indicate if areas have been assessed Hazards identified in high voltage activities (e.g. physical hazards) but are not directly involved in the electrical work, should be used when normally enclosed live electrical circuitry is exposed for maintenance or repair. This can include the use of cones or other means of fencing off the work area from unqualified or other employees not involved in the operation. Access Control Supervisors are responsible for installing, maintaining, and guarding equipment containing exposed energized electrical components that could be accessed by unauthorized persons. Access Control Safety warning signs must be posted on and or around the equipment to clearly identify exposed energized electrical components. Access Control Precautions must be taken to prohibit unauthorized, unqualified, or other 5 Check box to indicate if hazards are controlled Indicate how hazards are controlled Check box if work unit specific training is required UC Irvine – High Voltage Electrical Safety Program Areas to assess in high voltage activities Check box to indicate if areas have been assessed Hazards identified in high voltage activities (e.g. physical hazards) persons from performing tasks that might place them in contact with energized electrical circuits. These precautions may include posting signs or placing barriers to restrict access. Access Control Adequate access and working space shall be provided and maintained around all electrical equipment to permit ready and safe operation and maintenance of such equipment in accordance with 8 CCR 2932(a). Minimum Clearance – Follow Cal/OSHA access and clearance distances (Appendix D) for all high voltage activities. First Aid – First Aid equipment must be readily available and personnel trained in firstaid are on site. First Aid – An effective system of communication for contacting help has been established.
