In World War I, bags of sodium chloride (table salt) were placed in front of the propellant charges of artillery to suppress the flash. However, since the primary cause of the secondary flash is combustion of hydrogen and carbon monoxide, chemical approaches are also used. įlash suppressors attempt to suppress the flash mechanically, by interfering with the shock wave using either a cone or a series of slots at the muzzle of the firearm. Ingestion of the muzzle flash from aircraft mounted guns has also been implicated in compressor stall and flameout, causing loss of aircraft. Due to its brightness, muzzle flash can temporarily blind the shooter, or give away the shooter's location, especially at night. Muzzle flash, particularly the long duration secondary flash, is an inherent problem in most firearms. Following the dissipation of the muzzle flash, partially unburnt powder or other heated materials can be ejected from the muzzle and appear as sparks.Secondary flash is caused by the mixture of fuel-rich gases and oxygen in the atmosphere surrounding the muzzle. The secondary flash appears farthest from the muzzle as a large white or yellow flame.
