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
