● You can sell fireworks for the three weeks before November 5. All retailers can sell fireworks from October 15, but you need a special licence to sell them all year round ● Do not sell fireworks to under 18s – it is illegal for anyone under 18 to buy fireworks or even carry them in public ● The rules changed in 2005 for measuring the weight of fireworks that retailers are allowed to hold. In the past this was measured by the weight of the firework, but it will now be measured by the weight of the explosive content (NEC). The new maximum weight is 250kg NEC. As a rough rule of thumb the NEC weight is about one-quarter of the weight of the total packaging ● Retailers are responsible for preventing fires and explosions. This means they must prohibit smoking, keep hazardous or flammable material such as video cassettes or hosiery away from fireworks, and keep exit and escape routes clear ● Conduct a risk assessment for storing fireworks. For retailers employing more than five people, this must be a written document.
