Toxicity issues pertaining to burning pyrotechnics


We all know that normal operations with pyrotechnic compositions or other energetic materials, apart from the desired effect (e.g.: controlled blast from high explosives, propulsive power resulting from propellant gas pressure, various visible or sound effects from fireworks...) lead to the release of various products (gases, vapours, aerosols) in the environment, in relation with the chemicals, the reactions involved and some physical parameters. Although discussed from time to time by experts, and contrary to the case of 'conventional' fires, toxicity and environmentally related questions associated with burning pyrotechnics, have received far less attention than they actually deserve. Therefore, this paper supports an analysis of our current understanding of the sole toxicity problems (acute toxicity, sub-acute toxicity concerns...) emerging with all types of burning pyrotechnics, at the light of what has been established to address 'normal' fires in built environments. The paper provides an analysis of the regulatory context, lessons from past accidents, typology of chemistry and reactions of pyrotechnics, and some contribution to the analysis is supported by experiments on smoke powders, one significant family of products belonging to pyrotechnics. Eventually, a discussion is proposed to envisage pathways to go further in learning on those important issues.
