Summary
An alert describes ignition during pressure equalisation between composite air pressure vessels on a crown mounted compensator. Adiabatic compression heat or air-transfer static was identified as the ignition source. Rising pressure and temperature ruptured connecting pipework, leaving two employees with non-life-threatening injuries requiring shore-based treatment.
