KILLING SUPPLY EQUIPMENT AND LINES
Section 39.381 - General provisions

(a) When workmen depend on others for operating switches to kill circuits on which they are to work, or when they first secure special authorization from the chief operator before themselves operating such switches, the precautionary measures established in §§ 39.381-39.391 shall be taken in the order given, before work is begun on or about equipment or lines concerned, as a means for preventing misunderstanding and accident.

(b) In small organizations the chief operator may himself operate the switches and disconnectors instead of instructing others to do so, thus much simplifying and abbreviating the procedure. In certain cases the chief operator may direct the workman who wishes the section killed for his own protection, to operate some or all switches necessary himself, thus also abbreviating the procedure.

(c) In cases where there is no station with regular attendants at either end of a section of line to be killed for the protection of workers, the requirements of §§ 39.381-39.391 need not apply for disconnection of that end of the section concerned, if the employe under whose direction that end of the section is disconnected is in sole charge of the section and of the means of disconnection employed or if the point of disconnection at that end of the section is suitably tagged before work proceeds.
