(d) “Explosive composition” means a mixture or substance that, when ignited, may cause such a generation of highly heated gases that the resulting gaseous pressures are capable of producing destructive effects on contiguous objects.

(e) “Finishing and assembling building” means a structure in which fireworks are assembled and packed but are not mixed or pressed.

(f) (1) “Fireworks” means combustible, implosive or explosive compositions, substances, combinations of substances, or articles that are prepared to produce a visible or audible effect by combustion, explosion, implosion, deflagration, or detonation.
