Introduction
Measures to prevent coal gas poisoning generally include ensuring proper ventilation of coal-burning equipment, using coal-burning appliances correctly, installing carbon monoxide alarms, and regularly inspecting coal-burning devices. When using coal stoves, charcoal braziers, or similar equipment, place them in well-ventilated areas and avoid using them in enclosed spaces. If used indoors, a chimney must be installed and kept clear and unobstructed.
Measures to prevent coal gas poisoning generally include ensuring good ventilation for coal-burning equipment, using coal-burning appliances correctly, installing carbon monoxide alarms, maintaining indoor air circulation, and regularly inspecting coal-burning devices. A detailed analysis is as follows:
1. Ensure proper ventilation of coal-burning equipment: When using coal stoves, charcoal braziers, or similar devices, place them in well-ventilated areas and avoid using them in enclosed spaces. If used indoors, install a chimney and ensure it remains unobstructed so that smoke can be effectively vented outdoors, reducing the accumulation of coal fumes indoors.
2. Use coal-burning appliances properly: Avoid using accelerants such as gasoline or diesel when igniting a coal stove, as incomplete combustion may produce large amounts of carbon monoxide. When adding coal, act quickly to minimize the time the stove door or windows are open, preventing excessive release of fumes into the room. After use, promptly remove ash to maintain proper airflow within the stove.
3. Install carbon monoxide alarms: Install certified carbon monoxide detectors near coal-burning equipment and in areas where people spend significant time, such as bedrooms. Regularly check the battery level and operational status of the alarms. If dangerous levels of carbon monoxide are detected, the alarm will sound immediately, alerting occupants to take protective actions.
4. Maintain indoor air circulation: Even during cold weather, windows should be opened periodically while using coal-burning devices. Ventilate the room at least 2–3 times per day for 15–30 minutes each time to allow fresh air to enter, dilute any potential coal fumes, reduce carbon monoxide concentration, and prevent poisoning due to high gas levels.
5. Regularly inspect coal-burning equipment: Conduct monthly inspections of coal stoves, chimneys, pipes, and other related equipment to check for damage, blockages, or gas leaks. If any defects or abnormalities are found, repair or replace the equipment promptly to prevent smoke leakage caused by equipment failure and reduce the risk of poisoning.
If someone exhibits symptoms suggestive of coal gas poisoning—such as dizziness, nausea, or confusion—immediately move the person to a well-ventilated area and call emergency medical services.
