Tests were conducted at air bases and in a full-scale rig to evaluate the hazards of static electricity in POL systems. Field testing at two air bases revealed a low level of charge in JP-4 fuel delivered to aircraft through DOD filter-separators. The low levels result from the high conductivity of JP-4 due to the presence of approved DOD corrosion inhibitor and the design of filter- separators which provide considerable residence time for charge relaxation. Single stage filter separator units were shown to generate less charge than older two-stage units. Teflon screens charged at about half the level of paper separators. Aluminum hydrant systems were found to have a lower charging tendency than carbon steel systems.
