In a storage facility dedicated to recreational fireworks, a package containing firecrackers (1.4G category, originating in an Asian country) fell during unloading. A firecracker exploded and then, one by one, the remaining firecrackers wrapped in the same package popped, yet without causing any splattering capable of spreading fire. The alarm was sounded and the personnel reacted according to the posted procedure. The burning package was neutralised by the site’s fire prevention unit using multi-purpose powder extinguishers. External fire-fighters called to the scene did not need to intervene. Based on an investigation, the products were found to be defective. A poor seal of the fireworks envelope led to the release of a large quantity of pyrotechnics composition, which then ignited subsequent to mechanical aggression during handling.
Experts in this field have suggested strengthening quality controls as part of the product acceptance protocol.
