7.3. Safety measures when stopping pumping equipment
When stopping pumping equipment, the following safety requirements must be observed:
- stopping the pump for repairs and disassembling it must be carried out with the permission of the head of the station or the person replacing him and in accordance with the instructions in force;
- at the end of pumping, the valves at the intake and discharge of the pump must be closed.
Atswitchingpumps from working to standby and vice versa, the following safety requirements must be observed:
- when switching from a working pump to a standby one, the correct opening of the corresponding valves and the readiness of the pump for start-up should be checked;
- if it is necessary to repair a pump that is in reserve, the electric motor drive must be de-energized, and a sign “Do not turn on - people are working” is posted on the starting device of the electric motor. It is possible to remove the plate only with the permission of the NPS dispatcher or the person replacing him. It is forbidden to start up the unit with a warning sign posted;
- repair of a hot pump placed on standby should be started only after its casing temperature does not exceed 45 °C;
- standby pumps must be kept in such a state that they are ready to start as soon as possible after the stop of the working pump.
All of the above operations for starting, operating and stopping the pumps must be carried out taking into account the requirements of the manufacturer's instructions for the operation of specific equipment.
