Mars Pyrotechnics Ltd of Harlow, Essex, have been prosecuted and fined £5,000 by magistrates after they were found guilty of allowing five tonnes of fireworks to be stored dangerously. The case was brought against the company following work by Enfield Council's Trading Standards officers, who seized the fireworks at an Edmonton warehouse, in September 2004. This failure put Mars Pyrotechnics in breach of its health and safety duties, who believed that they were no longer responsible for the goods because they had sold them on to another party.
