How to Prevent Carbon Monoxide Poisoning in Daily Home Life

Carbon monoxide (CO) poisoning can generally be prevented in daily home life through measures such as proper use of gas appliances, installing carbon monoxide detectors, safe use of coal for heating, avoiding prolonged use of gas water heaters, and being cautious of automobile exhaust fumes. If any symptoms occur, seek medical attention promptly.

1. Proper Use of Gas Appliances

Regularly inspect gas pipelines, valves, stoves, and other equipment to ensure there are no leaks. When using gas, maintain good indoor ventilation—open windows or use exhaust fans—to promote air circulation and prevent CO accumulation.

2. Install Carbon Monoxide Detectors

Install carbon monoxide detectors in key areas such as the kitchen and bedrooms. These devices will sound an alarm immediately when CO concentrations exceed safe levels, alerting occupants to take prompt action and thereby preventing poisoning incidents.

3. Safe Use of Coal for Heating

Select high-quality, certified coal; avoid low-grade or impure coal, which may burn incompletely and produce excessive CO. When using coal for indoor heating, always install a chimney and ensure it remains unobstructed and airtight. Seal all chimney joints properly to prevent CO leakage into living spaces.

4. Avoid Prolonged Use of Gas Water Heaters

Gas water heaters must be installed in well-ventilated locations—such as outdoors or on a well-ventilated balcony—and must never be installed inside bathrooms or toilets. When operating a gas water heater, keep the bathroom or toilet door open to ensure adequate ventilation, and avoid extended use in enclosed spaces to prevent CO poisoning.

5. Be Cautious of Automobile Exhaust Fumes

Never idle a vehicle for extended periods in poorly ventilated areas such as garages or basements—even during winter. Vehicle exhaust contains high concentrations of CO, which can rapidly accumulate in enclosed spaces and cause poisoning.

We recommend learning about the hazards and prevention strategies for CO poisoning, and sharing this safety knowledge with all household members—especially vulnerable groups such as the elderly and children.
