Certain operations can give rise to accumulations of electric charge which may be released suddenly in electrostatic discharges with sufficient energy to ignite
Direct Answer
Option A: Flammable hydrocarbon gas/air mixtures
Electrostatic discharges, generated during operations like tank washing or cargo transfer, can ignite flammable hydrocarbon gas/air mixtures. The presence of oxygen (air) is crucial for combustion, making these mixtures highly susceptible to ignition from static electricity, as detailed in ISGOTT.
