Warning sign is a warning sign with black text on a yellow background
that warns o the danger o getting too close to or touching live parts o
the apparatus that can be dangerous
Work permit (WP) is a written permit to carry out a dened task in a
given place on an installation under given preconditions in a sae manner
Responsible or operations imply overall proessional supervision oelectrical installations, and ensuring that electrical installations are
planned, executed and operated in accordance with the regulations
High voltage installations are electrical installations with a nominal
voltage above 1000V alternate current or 1500V direct current
Earthed means that the electrical installation is short-circuited andconnected to the installations main earth so that electrical energy is
discharged quickly and saely in the event o short-circuiting
Condemned equipment is equipment that has been removed rom
operations permanently. The equipment has been electrically secured
(disconnected and earthed) and all labels have been removed.

INSTRUCTIONS FOR LEAKAGE TESTING
Before work begins
Check- that the pressure gauge and other test equipment has been calibrated and will
withstand the pressure that is to be tested- that the connected equipment will withstand the pressure that is to be tested- that any possible energy reservoirs such as accumulators, pulsation dampers,
etc. have been isolated
When using water as a test medium
- that the foundation and supports for the equipment to be tested will withstand thecombined weight of the equipment and water used during the test
Performance of pressure testing
When using water, the equipment shall be filled to 100% first - ensure that the gas is ventedat the highest point.
1. Increase the pressure to approx. 10% of the test pressure maximum 10 bar.2. Check for possible leaks (flanges, plugs, etc.).3. Increase the pressure gradually to 50% of the test pressure.4. Check for possible leaks (flanges, plugs, etc.).5. Increase the pressure gradually to the test pressure.6. Maintain the pressure for an adequate period of time in order to perform a thorough check
for leaks
- Avoid shock loads- Avoid passing in front of possible leakage points- Monitor any possible temperature variations that can influence the pressure
After pressure testing
1. Reduce the pressure gradually to atmospheric pressure
2. In the event of drainage :
- refill nitrogen at the highest point avoid creating a vacuum
- check that the drainage system is not overloaded
3. Check that all parts of the tested system have been depressurised/drained
low points, check valves, etc
