Alcohol or drugs contributed to 835 house fires in Scotland last year.

Fire services across the country urged people to be aware of the increased risks when drinking as the Fire Statistics Scotland 2010-2011 report was published. It revealed 11 people died and 248 were injured in such incidents last year.

The Chief Fire Officers Association (CFOA) said even a few glasses of wine or beer can dramatically add to the risks of an accidental fire.

It is encouraging homeowners to take extra care in light of the approaching bank holiday weekends and summer months.

CFOA chairman David Dalziel said: "Being under the influence of alcohol can affect your ability to escape should a fire occur, even with moderate consumption. We urge people not to put themselves or others at risk by smoking or cooking at home when they've had a drink."

Strathclyde accounted for almost half of the fires where drug or alcohol was a contributory factor – with 411 fires. The CFOA said the most common causes of fire where alcohol is involved are cigarettes, lighters, matches and cooking.

In the 6336 house fires in Scotland last year, 40 people lost their lives.
