This division sets forth safety and health standards that apply to the work conditions, practices, means, methods, operations, installations, and processes performed at telephone, TV cable, and other signaling equipment centers and installations, and at field installations used to transmit or control communication or other signals of the service supplier and may be located outdoors or in building spaces used for such field installations. “Center” work includes the installation, operation, maintenance, rearrangement, and removal of communications equipment and other associated equipment in telecommunications switching centers. “Field” work includes the installation, operation, maintenance, rearrangement, and removal of conductors and other equipment used for signal or communication service, and of their supporting or containing structures, overhead or underground on public or private rights of way, including buildings or other structures. (2) Employee protection in public work areas. (a) Before work is begun in the vicinity of vehicular or pedestrian traffic which may endanger employees, pedestrian and traffic control devices shall be provided for all operations on or adjacent to streets, alleys and walkways.

(b) Once a work area has been established, it shall be the employer’s responsibility to provide adequate supervision and periodic surveillance to assure that the above requirements are met. (3) Before work is performed on overhead lines, underground (such as in manholes), or in buried plants, the employer or designated representative shall make a complete evaluation of the work location to determine if a hazard exists or could be created in the performance of the work. The employer or designated representative shall determine from this evaluation, a safe procedure for performing the work and those means or methods shall be implemented before the work proceeds. Examples of possible worksite conditions that may be hazardous include, but are not limited to: (a) Manhole, pit, and pole locations, street intersections, alleys and isolated areas; (b) Weather and road conditions (such as ice, snow, and rain); (c) Visibility; (d) Time of day; (e) Manhole atmosphere conditions (such as explosive gases, exhaust fumes, and oxygen deficiency); (f) Jointly occupied manholes with foreign utilities; and (g) Power hazards.

(b) Rubber insulating equipment shall meet the electrical and physical requirements contained in ASTM Standard D-120-87, “Standard Specifications for Rubber Insulating Gloves,” and ASTM Standard D 1048-88(a), “Standard Specifications for Rubber Insulating Blankets,” with the exception that: (A) The maximum proof test current for a 14-inch Class I glove shall be no more than 14 mA; and with the further exception that: (B) Existing 14-inch Class I rubber gloves that meet a maximum proof test current of 16 mA and a minimum breakdown voltage of 17,000 volts (RMS) acquired prior to July 1, 1975 may be used as long as these gloves comply with the retest requirements of paragraph (f)(5) of 1910.268. (c) Patching rubber goods is prohibited; rubber protective equipment shall not be vulcanized or patched. (d) Rubber gloves for workers. A pair of approved rubber gloves and bag shall be assigned to each worker when workers are required to work on or be exposed to energized parts. (6) Equipment. (a) Ladder hooks. When ladder hooks are engaged the safety straps shall be lashed around the top rung and strand or otherwise secured to the strand. (b) Chain saw usage. (A) Chain saws shall be inspected prior to use and kept in good repair at all times. Saws with defective parts shall not be used. (B) Chain saw engines shall be shut off while being fueled. (C) Chain saws shall be equipped with an automatic throttle control which will return the engine to idling speed upon release of the throttle. (D) All employees using chain saws shall wear flexible ballistic nylon pads or other equivalent protection sewn or otherwise fastened to the trousers, which will protect the legs from the thigh to below the knee, except when working from an aerial lift device. (E) Chain saws shall not be brought into a bucket or work platform of an aerial lift device. Saws shall be carried on the outside of the aerial lift device. Chain saws shall be started and used only outside of the aerial lift device. (7) Training. The employer shall see that employees who operate derricks and cranes are properly trained as required in OAR 437, Division 2/N, OAR 437-002-0229(2), Crane Operator Training Requirements. (8) Handling poles near energized power conductors. (a) Insulating gloves shall be worn when handling the pole with either hands or tools, when there exists a possibility that the pole may contact a power conductor. Where the voltage to the ground of the power conductor exceeds 15kV to ground, Class II gloves (as defined in ASTM D1048-88a shall be used. For voltages not exceeding 15kV to ground, insulating gloves shall have a breakdown voltage of at least 17kV. (b) The guard or insulating material used to protect the pole shall meet the appropriate 3 minute proof test voltage requirements contained in ASTM D 1048-88a. (9) Fiber optic/lightwave transmission. (a) Only qualified employees shall install, service, maintain or use lightwave test equipment. (b) Employees shall avoid eye exposure to emissions from unterminated energized optical connectors. (c) Employees shall not look into vacant regenerator slots with an optical instrument. (d) Employees should not examine or look into broken, severed, or disconnected fiber optic cables. (e) Lightwave emissions may only be viewed with an indirect image converting device. (f) Microscopes, magnifying glasses and eye loupes shall not be used to examine energized fiber optic cables.
