Pump start-up: energy sources and direct controls

Starting pumps introduces rotating and pressure energy into pipework that may still be open or occupied by other trades.

High-energy check

Treat first start as high energy. Pressurising open or incomplete pipework is the main release scenario.

This task's main energy sources are not calculated by this tool. Use the trigger checks below and competent-person verification.

Trigger checks

Mechanical
Moving parts, tools, tension, rotation or stored mechanical force.
Electrical
Current, voltage, energisation, arc flash or stored electrical energy.
Pressure
Compressed gas, liquid, hydraulic, pneumatic or vacuum energy.

Direct controls to verify

Ticks stay on this screen only. Nothing is saved or sent.

System boundary being pressurised is confirmed closed.
Open ends and incomplete joints are verified closed before the start.
Other trades on the system are informed before the start.
Start is authorised by a named person.
Rotation direction and guards are checked before load is applied.
Stop if pressure or flow behaves unexpectedly.

For your SPA or pre-start

State the system boundary being pressurised, how open ends are verified closed, who authorises the start and how other trades are informed.
