Terry Carter, Principal Trading Standards Officer, said: “We understand the short-term difficulties a petrol strike will cause people but public safety is our number one concern - therefore we would strongly advise people to be sensible and not to take unnecessary risks with fuel.
“As with all highly flammable liquids, there are obvious safety and legal issues associated with the storage of fuel around the home, which could result in increased risks to both residents and firefighters in the event of a fire."
Wiltshire Fire & Rescue Service has reminded people not to store fuel in their homes, after a woman in Yorkshire was badly burned in an explosion.
The woman accidentally set fire to herself after trying to decant petrol from one container to another using a jug in her kitchen.

Area Manager John Popowicz said: “Given that there is no industrial action affecting fuel supplies as yet, our advice would be to not store fuel at home, as it is a significant fire risk.
"If you do need to have flammable materials on your premises, you should never bring them into the domestic part of the home."
