Firefighters have urged smokers to take the ‘Stoptober’ challenge.
People were encouraged to take part in the national campaign to kick the habit for 28 days in October.
Two thirds of fatal house fires over the last two years were smoking related, said West Sussex Fire and Rescue Service.
Nicki Peddle, the brigade’s safer communities manager, said: “Of course, we know that not every smoker is ready to give up.
“For those people, the best advice we can offer to prevent a fire breaking out is to dispose of their cigarettes carefully and safely and to avoid lighting up in bed.”
