Investigation FindingsEquipment supplied was different to that in Method Statement
absence of pilot burner (as MS) forced ignition with full gas flow
HTPL unaware of the risks of burner ignition
no control on air purge prior to ignition
pressure reducing valve used as on-off valve (gas pressure too high)
burner valve suspected to be passing (based on testing)
delay (due to data logger) between air purge and ignition gas gave opportunity for
accumulation of explosive gas mixture in vessel
flame eye disconnected for ignition forced SOV override open
open SOV left only single valve isolation between gas supply and vessel
Position of operator
manual gas valve and air damper operation required operator to work close to temporary
burner at ignition18
