Ms Hill's injury has prompted firefighters to issue another warning to people about storing petrol in their homes.
Peter Hudson, of North Yorkshire Fire and Rescue Service, said: "In domestic situations fuel containers must not be stored in living accommodation such as kitchens, living rooms and bedrooms or under staircases."
He added: "Never bring petrol inside your home. If you do smell petrol fumes in a garage or outbuilding ventilate the area and make sure nobody smokes or turns electrical switches on or off.
"The slightest spark could cause an explosion."
Meanwhile, Unite, which represents around 2,000 fuel tanker drivers, ruled out the threat of strikes over Easter and said it wanted to focus on talks.
The AA has warned of "stupid and very dangerous" actions being taken by panicked drivers.
In a statement, the motoring organisation said that in Macclesfield, Cheshire, one observer had seen an elderly woman using a petrol pump to fill jam jars.
Another man was seen at the same petrol station filling one gallon washing-up liquid bottles with fuel.
AA president Edmund King said: "Some people seem to have lost any sense of proportion."
