The annual appeal by Middlesbrough Trading Standards calls on the public to help keep the Bonfire period safe by stamping out illicit sales.
They’re keen to hear from people with information – always given in confidence – about sales of fireworks from private houses.
Fireworks sold on the black market often do not comply with the required safety standards and can be unstable, and they can pose a fire risk even in storage.
Illegal sellers are the main suppliers to children, and their products can result in serious injury and worse.
Councillor Julia Rostron, Middlesbrough Council’s Executive member for Adult Health and Social Care, said: “Bonfire night is a great time of year for the whole family to enjoy, and fireworks are a key part of the spectacle.
“But they’re also highly dangerous, so it’s essential that they’re manufactured, stored and used in compliance with the law.
“That’s why we need the public’s help to crack down on the unscrupulous sellers who are putting lives at risk.
“Fireworks can maim and even kill and it is only a matter of time before someone gets seriously hurt or even killed.
“Do you really want to be living next door to an explosives store?
“People should remember that these are explosives, so why hand a dangerous weapon to a child?”
Anyone with information on illegal firework sales is asked to call the Fireworks Hotline in confidence on 01642 728223 to enable Middlesbrough Trading Standards to take action to protect your neighbourhood.
