Recently, news of a man suffering carbon monoxide poisoning after roasting sweet potatoes indoors with windows closed has drawn widespread attention. According to media reports, the man used charcoal to roast sweet potatoes in a sealed room for convenience. Due to poor ventilation, incomplete combustion generated a large amount of carbon monoxide, causing him to lose consciousness. Fortunately, he was rushed to the hospital in time and has since recovered.Carbon monoxide (CO) is a colorless, odorless, and non-irritating toxic gas commonly produced when carbon-based fuels—such as charcoal, gas, or kerosene—burn incompletely in low-oxygen environments. Once inhaled, CO binds to hemoglobin in the blood more effectively than oxygen, preventing oxygen delivery to tissues. This can lead to symptoms ranging from headaches and nausea to unconsciousness or even death.Experts warn that such incidents are more common in winter. Never use open flames for heating or cooking in enclosed spaces. If using charcoal or gas appliances, ensure adequate ventilation and consider installing a carbon monoxide detector for early warning. If symptoms like dizziness, weakness, or nausea occur, immediately open windows, leave the area, and call emergency services if necessary.
近日，一则‘男子在屋内关窗烤地瓜导致一氧化碳中毒’的新闻引发广泛关注。据媒体报道，该男子为图方便，在密闭房间内使用炭火烤制地瓜，因通风不良，燃烧不充分产生大量一氧化碳，最终导致中毒昏迷，所幸被及时送医抢救，脱离生命危险。一氧化碳（CO）是一种无色、无味、无刺激性的有毒气体，常由含碳燃料（如木炭、煤气、煤油等）在氧气不足条件下不完全燃烧产生。人体吸入后，一氧化碳会与血红蛋白结合，阻碍氧气输送，造成组织缺氧，轻则头痛、恶心，重则昏迷甚至死亡。专家提醒：冬季是此类事故高发期，切勿在密闭空间内使用明火取暖或烹饪。若需使用炭火、燃气设备，务必保持良好通风，并建议安装一氧化碳报警器，以提前预警风险。一旦出现头晕、乏力、恶心等症状，应立即开窗通风并撤离现场，必要时拨打急救电话。
