A large quantity of fireworks, seized in a campaign to reduce Bonfire Night accidents last year, are to be destroyed in Greater Manchester.
About 1.5 tonnes of explosives will be destroyed
About 1.5 tonnes of explosives will be either let off or burnt at a secret and secure location on Tuesday.
Greater Manchester Fire Service said the fireworks were a public danger.
Assistant County Fire Officer Steve Beckley said: "Every year we come across people who are storing fireworks inappropriately."
He added: "More often than not they are not licensed and not registered.
"There is a legal responsibility on anyone selling or storing fireworks to ensure they comply with legislation which is there to protect their safety and that of the general public.
"Fireworks if misused can be extremely dangerous and we work very closely with our partners and take whatever action necessary to ensure that people comply with the law.
"This destruction is a direct result of excellent work we and our partners are doing to reduce the danger to our communities from illegal fireworks."
