Cause & Consequence
- Uncontrolled release of a flammable gas or liquid
Specific Incident Equipment
Swagelok fitting on fuel gas system
The HVAC system to the enclosure was also investigated and found not to be functioning 100% correctly
It is suspected that this may have contributed to the build-up of gas in the enclosure if a weep were present. It was decided that it was safe to start up the gas turbine and, using an operational risk assessment (ORA), monitor the enclosure for fuel-gas leaks for the following two weeks.
Complete ORA to allow operation of the turbine while monitoring enclosure and fuel gas cabinet for hydrocarbon levels. ORA to run for two weeks from start-up.
