Use cool humidifiers, not hot steam vaporizers. A vaporizer can cause severe burns if a child overturns it or puts his face too close to it. Supervise children around fires, stoves, and heaters of any kind. Use flame-resistant sleepwear. Give up smoking, or at least carefully dispose of used cigarettes.
Cigarettes are the most common cause of fires in homes.
Keep cigarette lighters away from children. Install smoke detectors in your home on every floor. Check them monthly for proper functioning. More people die from smoke inhalation than from burns. Smoke alarms detect smoke long before your nose can.
