Hereford and Worcester Fire and Rescue Service is supporting National No Smoking Day on Wednesday, March 13.
While smoking is one of the biggest causes of death and illness in the UK, accidental fires started by cigarettes and other smoking materials kill more people than any other type of fire.
These incidents are most likely to happen in the living room, closely followed by the bedroom.
HWFRS is calling on smokers to quit if they can but to otherwise always be vigilant when smoking or disposing of materials.
Emma Roberts, HWFRS Head of Prevention, said: “No Smoking Day provides us with the ideal opportunity to encourage people to consider giving up smoking.
“Where this isn’t possible, we are asking people to be extra vigilant when putting out cigarettes.”
