Introduction
Measures to prevent carbon monoxide poisoning generally include the proper use of charcoal heating devices, installation of certified carbon monoxide alarms, regular indoor ventilation, and avoiding the use of fuel-powered equipment in enclosed spaces. When using a charcoal brazier or coal-burning stove for heating, ensure a fully installed chimney is set up above the device to allow smoke to be effectively vented outdoors. After adding coal, promptly cover the stove to minimize the release of smoke into the indoor environment.
Preventive measures against carbon monoxide poisoning generally include the proper use of charcoal heating devices, installation of certified carbon monoxide detectors, regular indoor ventilation, routine maintenance of gas appliances, and avoiding the use of fuel-powered equipment in enclosed spaces. Specific details are as follows:
1. Proper use of charcoal heating devices: When using charcoal braziers or coal stoves for heating, ensure a complete chimney system is installed above the device to allow smoke to be safely vented outdoors. After adding coal, promptly cover the stove to minimize indoor smoke dispersion. When sleeping at night, leave a small gap in windows to prevent toxic gases from accumulating in tightly sealed rooms.
2. Install certified carbon monoxide alarms: Place safety-standard-compliant detectors in frequently occupied areas such as bedrooms and living rooms, especially near gas appliances. Check the alarm’s functionality monthly and replace batteries when depleted. If an alarm sounds, immediately evacuate all family members to a safe outdoor area.
3. Maintain regular indoor ventilation: Always turn on exhaust fans or open windows when using gas water heaters for bathing or cooking. Even during cold winter months, open windows for ventilation 2–3 times daily, each time for at least 15 minutes, to ensure adequate air circulation and reduce indoor carbon monoxide levels.
4. Perform regular maintenance of gas appliances: Have qualified technicians inspect gas water heaters, stoves, and pipelines every quarter to ensure they are functioning properly. If you detect a gas odor, immediately shut off the main valve, open doors and windows for ventilation, avoid operating electrical switches or creating sparks, and contact a professional for repairs.
5. Avoid using fuel-powered equipment in enclosed spaces: Do not operate vehicles or generators for extended periods in enclosed areas such as garages or basements. When using fuel-powered equipment, ensure the space is well-connected to the outside environment so that carbon monoxide in exhaust fumes can be promptly discharged, preventing dangerous concentration buildup.
If someone nearby exhibits symptoms suggestive of carbon monoxide poisoning—such as weakness, vomiting, or confusion—immediately move them to a place with fresh air and call emergency medical services. Educate family members about prevention measures, particularly reminding children and elderly individuals to stay away from hazardous equipment. Before using any newly purchased gas or coal-burning appliance, confirm it meets safety standards.
