Liquid Fuel Fire

1 What is the name of the 2 What are its specific objectives related to the Priority Unwanted
critical control for Liquid
Event (PUE)?
Fuel Fire?
Early detection of creeping failures Proactively detect early causes of creeping failure by carrying out regular inspection,
testing and maintenance and decrease the likelihood of incidents

3 What are the critical 4 What are the activities 5 What can be sampled from
the set of activities for

objectives? having the critical control clear image of the critical
able to do what is required? control status?
Regular inspection for leaks around fuel Scheduled preventative maintenance Frequency of inspection and number of
systems (storage vessels, bunds/dikes, and inspection walkaround in CMMS findings
pump, pipeworks, flanges) Report deviation/failure as near miss on Number of iCare reports on detected
iCare leaks
Field verification of installation for visible
leaks

NDT Testing on storage vessels, pipework Written scheme of NDT testing/piping Evidence of NDT tests, thickness
elbow/bends to identify erosion or specificaiton measurements and findings
thickness reduction NDT Testing are in CMMS schedule Overdue NDT tests in CMMS
Flexible hoses are maintained as per the DSCQP thinckess and corrosion List of assets/equipment at risk
manufacture’s instruction measurement
Flexi hose register with maintenance
records

Prevent pump seal/gasket failure by Preventive Maintenance Routines are Pump/seal selection according to the fuel
having a preventive maintenance schedule on CMMS Number of reported pump seal leaks
routine. If low flash point fuel is used Report deviation/failure as near miss on
then double seals or magnetic drive iCare
pumps
Pump and seal selection in maintenance
instruction/work order
