Fortunately, most fires are preventable. If a grease fire should occur, never put water on it. It will only cause the grease to splatter, burning you or spreading the fire.
Cigarettes are the leading cause of fire deaths.
Never smoke in bed or in a place where you may fall asleep. Also, use deep ashtrays. Keep matches and lighters up high, out of the reach and sight of children. Don't use light bulbs with greater wattages than a fixture can handle. Leave plenty of air space around appliances and television sets.
