Where Subpart K does not already cover it, cord- and plug-connected equipment must, in place of 1926.302(a)(1), either have a cord whose equipment grounding conductor is tied to the frame and to a grounding means (not allowed where bringing a ground into the work area raises the hazard), be double-insulated per Subpart K, or be fed through an isolating transformer whose ungrounded secondary is no more than 50 volts. Portable and vehicle-mounted generators supplying such equipment may feed only equipment on the generator or vehicle and cord-and-plug equipment plugged into receptacles on the generator or vehicle itself. Non-current-carrying metal parts and the grounding terminals of receptacles are bonded to the generator frame; for vehicle-mounted units the generator frame is bonded to the vehicle frame; any neutral is bonded to the generator frame. For hydraulic and pneumatic tools, 1926.302(d)(1) does not apply to hydraulic fluid in insulating sections. No tool, hose, valve, pipe, filter or fitting may run above its safe operating pressure (with hazardous defects no pressure is safe; otherwise the maximum rated pressure is the limit). Tools that may contact exposed energized parts must be designed and maintained for that use. Hydraulic systems for tools that may touch live parts must guard against loss of insulating value from a partial vacuum in the line (long lines without check valves, more than 10.7 m (35 ft) from reservoir to top, promote this). Pneumatic tools used on or near energized parts must guard against moisture in the air supply. Pressure is bled off before connections are broken, unless the connectors are the quick-acting, self-closing kind. Employees must not use any part of the body to find or stop a hydraulic leak, and hoses may not be kinked.
