(I) Protection of the body and exposed parts and other protective equipment. (1) All persons who work in such a manner that their clothing may become wet with acids caustics or other injurious liquids will be provided with such gloves, aprons, coats, jackets, sleeves, or other garments made of rubber, or other materials impervious to such liquids as are needed to keep their clothing dry. Aprons will extend well below the top of boots to prevent such liquid from splashing into the boots. Provision of dry clean cotton clothing along with rubber shoes or short boots and an apron impervious to such liquids will be considered a satisfactory substitute where small parts are cleaned, plated, or acid-dipped in open tanks and rapid work is required.(2) Facilities for quick drenching or flushing of the eyes and body will be provided within the work area, where employees are exposed to injurious corrosive materials. Where plumbing is not available and where storage batteries of the enclosed type with explosion-proof vents are serviced exclusively, portable, self-contained eyewash equipment may be provided in lieu of the quick drenching or flushing facilities. Where portable self-contained eyewash equipment is used in lieu of drenching or flushing facilities, it will be capable of delivering to the eye no less than 1.5 liters (0.4 gallons) per minute for a minimum of fifteen minutes.(3) Welding, cutting, brazing, and molten metal exposures. All employees exposed to the hazards created by welding, cutting, brazing, or molten metal operations will be protected by protective clothing. This includes:
(a) Flameproof gauntlet gloves.(b) Flameproof aprons made of leather, or other material which provides equivalent protection.(c) Exterior clothing made of wool, cotton, or other material chemically treated to reduce combustibility.(d) Capes or shoulder covers made of leather or other material which provides equivalent protection.(e) Protection for the ears from the overhead welding and cutting or welding and cutting in extremely confined spaces.(4) Working by hand on energized circuits. When an employee works on, or in proximity to, energized lines, the employer will provide and the employee will use protective equipment approved for the hazards involved.
(5) Climbers. (a) Where employees climb poles or trees, the employer will provide climbers, the appropriate gaffs (spurs). Pole gaffs will measure at least one and seven-sixteenth inches (36.5 mm) on the underside. Tree gaffs will measure no more than three and one-half inches (88.9 mm) nor less than two and one-fourth inches (57.2 mm) on the underside.(b) Storage. Storage facilities will be provided so that the sharp points of the climber gaffs will not cause damage to other equipment or cause injury to employees.
(6) Safety belts, harness, lifelines and lanyards. (a) Lifelines, safety belts or harnesses and lanyards will be provided by the employer, and it is the responsibility of the employee to wear such equipment when exposed to hazards of falling where the operation being performed is more than four feet above the ground or above a floor or platform, except as otherwise specified in this chapter, and when working on stored material in silos, hoppers, tanks, and similar storage areas. Lanyards and vertical lifelines will have a minimum breaking strength of five thousand pounds. Anchorage used for attachment of personal fall arrest equipment will be independent of any anchorage being used to support or suspend platforms and capable of supporting at least five thousand pounds per employee attached.(b) Where the lifeline may be subjected to cutting or abrasion, a minimum seven-eighths-inch wire core manila rope, or equivalent, will be provided. For all other lifeline applications, a minimum of three-fourths-inch manila rope, or equivalent, will be provided.(c) Safety belt, harness, or strap lanyards will be a minimum of one-half inch nylon, or equivalent, with a maximum length to provide for a fall of no more than six feet. The lanyard will have a breaking strength of no less than five thousand pounds.(d) All safety belt, harness, or strap and lanyard hardware will be drop-forged or pressed steel, cadmium plated. Surface will be smooth and free from sharp edges.(e) All safety belt, harness, or strap and lanyard hardware will be capable of withstanding a tensile loading of five thousand pounds without cracking, breaking, or becoming permanently deformed.(7) Safety nets.(a) Safety nets will be provided when workplaces are more than twenty-five feet above the ground, water, or other surface where the use of ladders, scaffolds, catch platforms, temporary floors, safety lines, or safety belts is impractical.(b) Where safety net protection is required by this rule, operations will not be undertaken until the net is in place and has been tested.(c) Nets will extend outward from the outermost projection of the work surface in accordance with table 17-1 to this rule and will be installed as close under the work surface as practical but in no case more than thirty feet below such work surface with the exception of bridge construction where only one level of nets is needed. Nets will be hung with sufficient clearance to prevent the falling employee's contact with the surface or structures below. Such clearance will be determined by impact load testing. Table 17-1
Table
Vertical distance from working level to horizontal plane of the net. | Minimum required horizontal distance of net from the edge of the working surface. |
Up to five feet | eight feet |
More than five feet up to ten feet | ten feet |
More than ten feet | thirteen feet |
(d) The mesh size of nets will not exceed six inches. All new nets will meet accepted performance standards of seventeen thousand five hundred foot-pounds minimum impact resistance as determined and certified by the manufacturer, and will bear a label of proof test. Edge ropes will provide a minimum breaking strength of five thousand pounds.(e) Forged steel safety hooks or shackles will be used to fasten the net to its supports. Attachment of safety nets to the working platform is not permitted.(f) Connections between net panels will maintain the full strength of the net.(8) Working over or near water. (a) Where employees are working over or near water, and where the depth or current of the water creates a danger of drowning, the employer will provide U.S. coast guard-approved life jackets or buoyant work vests for each employee.(b) Ring buoys with no less than ninety feet of line attached will be provided and readily available for emergency rescue operations. Distance between ring buoys cannot exceed two hundred feet.(c) At least one lifesaving skiff will be immediately available at locations where employees are working over or adjacent to water.(d) In cribs and cofferdams where employees are exposed to danger of falling inside of the enclosure containing water, a life raft will be provided.(9) Night work. When working at night, spotlights or portable lights for emergency lighting will be provided as needed to perform the work safely.
(10) Barriers and warning devices. The employer will provide barriers and effective warning devices such as flasher lights, "Men Working" signs, cones, flares, lanterns, flags and reflectors, for the protection of employees when work is performed in congested areas and where employees are exposed to traffic hazards or other working conditions where a hazard may exist.
