冬季是一氧化碳中毒的高发期，主要由于取暖设备使用不当或通风不良所致。一氧化碳（CO）是一种无色、无味、无刺激性的有毒气体，一旦吸入过量，会与血液中的血红蛋白结合，阻碍氧气输送，导致组织缺氧，严重时可致昏迷甚至死亡。以下行为需高度警惕：1. 在密闭空间内使用炭火、煤炉或燃气热水器取暖或做饭，未安装排烟管道或通风不畅；2. 长时间在车库内发动汽车，尤其车窗关闭时，尾气中的一氧化碳易积聚；3. 使用老旧或不合格的燃气设备，如热水器、灶具等，存在泄漏风险；4. 睡觉前未检查取暖设备是否关闭，或在卧室使用明火取暖。预防措施包括：保持室内良好通风，定期检修燃气设备，安装一氧化碳报警器，并避免在密闭环境中使用燃料燃烧设备。一旦出现头晕、恶心、乏力等症状，应立即开窗通风并撤离现场，必要时及时就医。提高安全意识，科学使用取暖设备，是防范一氧化碳中毒的关键。
Winter is the peak season for carbon monoxide (CO) poisoning, primarily caused by improper use of heating appliances or poor ventilation. Carbon monoxide is a colorless, odorless, and non-irritating toxic gas. When inhaled in excess, it binds to hemoglobin in the blood, blocking oxygen delivery and leading to tissue hypoxia—potentially causing unconsciousness or even death.Behaviors that warrant caution include:1. Using charcoal, coal stoves, or gas water heaters for heating or cooking in enclosed spaces without proper ventilation or exhaust systems;2. Running a car engine for extended periods inside a closed garage, where CO from exhaust fumes can quickly accumulate;3. Using outdated or substandard gas appliances (e.g., water heaters, stoves) that may leak CO;4. Failing to turn off heating devices before sleeping or using open-flame heaters in bedrooms.Preventive measures include ensuring good indoor ventilation, regularly inspecting gas appliances, installing CO detectors, and avoiding fuel-burning devices in confined spaces. If symptoms such as dizziness, nausea, or fatigue occur, immediately open windows, leave the area, and seek medical help if necessary.Raising awareness and using heating equipment safely are key to preventing carbon monoxide poisoning.
