Working near exposed energized parts in confined spaces.

(1) For working in a confined or enclosed space (such as a manhole or vault) that contains exposed energized parts, the employer must provide, and the employee must use, protective shields, protective barriers, or insulating materials that are necessary to avoid contact with these parts. Doors, hinged panels, and the like must be secured to prevent swinging into an employee and causing the employee to contact exposed energized parts.
(2) Conductive materials and equipment that are in contact with any part of an employee's body must be handled in a manner that will prevent them from contacting exposed energized conductors or circuit parts. If an employee handles long conductive objects (such as ducts and pipes) in areas with exposed live parts, the employer must institute work practices (such as the use of insulation, guarding, and material handling techniques) that will minimize the hazard.
(3) Portable ladders must have nonconductive siderails if they are used where the employee or the ladder could contact exposed energized parts.
(4) Conductive articles of jewelry and clothing must not be worn if they might contact exposed energized parts.
