1 Pumping Units 11.1 WELL PUMPING UNITS 11.1.1 Electric power to the pumping unit should be deen- ergized a sufficient distance from the wellhead to eliminate potential electrical hazards during well servicing operations. In confined locations, overhead electric power to the pumping unit control panel should be deenergized. Where necessary, electric power service should be deenergized while moving the rig in or out and during rig-up and rig-down operations. 11.1.2 When well servicing operations are to be per- formed, the pumping unit should be turned off, the brake set, and where applicable, the power source locked out/tagged out.

11.1.3 If the pumping unit is stopped with counterweights in other than the down position, additional means to secure the beam to a fixed member of the pumping unit shall be used to prevent any unintended movement of the counterweights or beam. 11.1.4 Chain or wire rope sling of suitable strength should be used to handle the horsehead if removal or installation operations are necessary. On installation, the horsehead should be bolted or latched in accordance with ansi download the manufac- turer's specifications.
