The Toys (Safety) Regulations 1995

Functional toys

3.  Functional toys or their packaging shall bear the marking “Warning: to be used under the direct supervision of an adult”.

In addition, these toys shall be accompanied by directions giving working instructions as well as the precautions to be taken by the user, with the warning that failure to take these precautions would expose the user to the hazards—to be specified—normally associated with the appliance or product of which the toy is a scale model or an imitation. It will also be indicated that the toy must be kept out of the reach of very young children.

“Functional toys” means toys which are used in the same way as, and are often scale models of, appliances or installations intended for adults.
