Over a third of consumer fireworks used by children are unsafe and will be taken out the market, government inspectors have said, following an investigation.

The ILT tested some 40 different types of F1 fireworks, which are available year-round and are supposed to be safe to use by children and inside the house.

Over a third of the tested fireworks did not to comply with safety norms. Two types of fireworks exploded during the test and other articles went out after being ignited.

“That is dangerous because it may explode when a person takes a look to see why nothing is happening,”  the agency said.

Other fireworks sent out sparks to over 1.5 metres, increasing the likelihood of spreading a fire.

Importers have been told to take the fireworks off the market and destroy them.

According to VeiligheidNL, which monitors injuries caused by fireworks, half of the victims of accidents involving F1 fireworks are younger than 12, which is below the legal age to use any fireworks.

F1 fireworks do not fall under the national fireworks ban, which may come into effect from New Year’s Eve 2026.
