There have been several documented incidents where ignition has occurred during a flammable gas blowdown. In some instances, gas lines were being cleaned, while in others, the blowdown was completed as a safety measure for another process. Here, we focus on case studies where a stream of flammable gas was ignited during a blowdown and an obvious ignition source (other than electrostatic discharge) was not present, but foreign material was observed before, during, or after the incident. The potential influence of particle size and material properties is presented. We also discuss guidance offered by the available literature on the control of electrostatic ignition hazards in flammable gas streams.
