Chapter 296-24 WAC General Safety and Health Standards Part L Electrical (c) Employees standing on the ground must not contact the vehicle or mechanical equipment or any of its attachments, unless: (i) The employee is using protective equipment rated for the voltage; or (ii) The equipment is located so that no uninsulated part of its structure (that portion of the structure that provides a conductive path to employees on the ground) can come closer to the line than permitted in this section. (d) If any vehicle or mechanical equipment capable of having parts of its structure elevated near energized overhead lines is intentionally grounded, employees working on the ground near the point of grounding must not stand at the grounding location whenever there is a possibility of overhead line contact. You must take additional precautions, such as the use of barricades or insulation, to protect employees from hazardous ground potentials, depending on earth resistivity and fault currents, which can develop within the first few feet or more outward from the grounding point. (9) Illumination. (a) Employees must not enter spaces containing exposed energized parts, unless illumination is provided that enables the employees to perform the work safely. (b) Where lack of illumination or an obstruction precludes observation of the work to be performed, employees must not perform tasks near exposed energized parts. Employees must not reach blindly into areas which may contain energized parts. (10) Confined or enclosed work spaces. When an employee works in a confined or enclosed space (such as a manhole or vault) that contains exposed energized parts, you must provide, and the employee must use, protective shields, protective barriers, or insulating materials as necessary to avoid inadvertent contact with these parts. Doors, hinged panels, and the like must be…

Chapter 296-24 WAC General Safety and Health Standards Part L Electrical (B) Ropes and handlines used near exposed energized parts must be nonconductive. (ii) You must use protective shields, protective barriers, or insulating materials to protect each employee from shock, burns, or other electrically related injuries while that employee is working near exposed energized parts which might be accidentally contacted or where dangerous electric heating or arcing might occur. When normally enclosed live parts are exposed for maintenance or repair, they must be guarded to protect unqualified persons from contact with the live parts. (2) Alerting techniques. You must use the following alerting techniques to warn and protect employees from hazards which could cause injury due to electric shock, burns, or failure of electric equipment parts: (a) Safety signs and tags. You must use safety signs, safety symbols, or accident prevention tags where necessary to warn employees about electrical hazards which may endanger them. (b) Barricades. You must use barricades in conjunction with safety signs where it is 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. (c) Attendants. If signs and barricades do not provide sufficient warning and protection from electrical hazards, you must station an attendant to warn and protect employees. (3) Design requirements. Insulating blankets, ,matting, covers, line hose, gloves, and sleeves made of rubber must meet the following requirements: (a) Manufacture and marking.

Safety-related work practices shall be employed to prevent electric shock or other injuries resulting from either direct or indirect electrical contacts, when work is performed near or on equipment or circuits which are or may be energized. The specific safety-related work practices shall be consistent with the nature and extent of the associated electrical hazards. ## 1910.333(a)(1) "Deenergized parts." Live parts to which an employee may be exposed shall be deenergized before the employee works on or near them, unless the employer can demonstrate that deenergizing introduces additional or increased hazards or is infeasible due to equipment design or operational limitations. Live parts that operate at less than 50 volts to ground need not be deenergized if there will be no increased exposure to electrical burns or to explosion due to electric arcs. Note 1: Examples of increased or additional hazards include interruption of life support equipment, deactivation of emergency alarm systems, shutdown of hazardous location ventilation equipment, or removal of illumination for an area. Note 2: Examples of work that may be performed on or near energized circuit parts because of infeasibility due to equipment design or operational limitations include testing of electric circuits that can only be performed with the circuit energized and work on circuits that form an integral part of a continuous industrial process in a chemical plant that would otherwise need to be completely shut down in order to permit work on one circuit or piece of equipment.

Chapter 296-24 WAC General Safety and Health Standards Part L Electrical (i) Employees' hands must not be wet when plugging and unplugging flexible cords and cord- and plug-connected equipment, if energized equipment is involved. (ii) You must only handle energized plug and receptacle connections with insulating protective equipment if the condition of the connection could provide a conducting path to the employee's hand (if, for example, a cord connector is wet from being immersed in water). (iii) You must properly secure locking-type connectors after connection. (2) Electric power and lighting circuits. (a) Routine opening and closing of circuits. You must use load rated switches, circuit breakers, or other devices specifically designed as disconnecting means for the opening, reversing, or closing of circuits under load conditions. You must not use cable connectors not of the load-break type, fuses, terminal lugs, and cable splice connections for such purposes, except in an emergency. (b) Reclosing circuits after protective device operation. After a circuit is deenergized by a circuit protective device, you must not manually reenergize the circuit until it has been determined that the equipment and circuit can be safely energized. The repetitive manual reclosing of circuit breakers or reenergizing circuits through replaced fuses is prohibited. - Note: When it can be determined from the design of the circuit and the 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 reenergized.
