Fireworks sold through the black economy – particularly from private residences, street hawkers, pub sellers, car boot sales and online – may be unsafe and dangerous.
Local retailers selling fireworks are required to register with the Notts County Council’s Trading Standards team.
Officers are visiting premises selling fireworks throughout the county this week to make sure their products are correctly stored.
Coun Alice Grice, vice-chair of Notts County Council’s community safety committee, said: “Fireworks are explosives that can cause a great deal of damage and harm if they are stored incorrectly so we are checking registered premises.”
