Some plant incidents involving unexplained ignition sources are detailed [1]. The reason why less energetic sparks will ignite a dust cloud while more energetic sparks will not is that the latter expel dust particles from the ignition zone, while the former do not [2]. The ignition of liquid decane under high intensity CO ₂ laser irradiation (1 5 kW/cm ²) was studied [3], as was ignition of flammable atmospheres by laser beams emergent from optical fibres for various wavelengths and targets...
