Recently, a video circulating online has drawn widespread public attention: a street vendor appeared to place a liquefied petroleum gas (LPG) cylinder directly over an open flame, allegedly due to cold weather. This dangerous act has raised serious concerns about gas safety. While it’s true that LPG cylinders may experience reduced vaporization and weaker flame output in low temperatures, heating them with an open flame is extremely hazardous. As the temperature rises, internal pressure inside the tank increases rapidly; if it exceeds the cylinder’s structural limits, an explosion can occur, leading to severe injuries and property damage. According to China’s Urban Gas Management Regulations and related safety guidelines, it is strictly prohibited to heat, expose to direct sunlight, or invert LPG cylinders during use. Experts advise that if weak flame output occurs in winter, users should inspect regulators and hoses for blockages or simply replace the cylinder—never resort to heating it. Authorities are also urged to enhance safety education and oversight among street vendors to prevent such high-risk practices and ensure public safety.
近日，一段视频在网络上引发广泛关注：一名摊主疑似因天气寒冷，将液化气罐直接放在明火上加热。这一危险行为迅速引发公众对燃气安全的担忧。液化石油气（LPG）罐在低温环境下确实可能出现气化不足、火力变小的情况，但将其置于火源上烘烤极其危险。液化气罐内部压力随温度升高而急剧上升，一旦超过罐体承受极限，极易发生爆炸，造成严重人身伤害和财产损失。根据中国《城镇燃气管理条例》及相关安全规范，严禁对液化气钢瓶进行加热、暴晒或倒置使用。专家提醒，若冬季使用液化气出现火力不足，应检查减压阀、管道是否堵塞，或更换新罐，切勿采取加热等危险方式。相关部门也应加强街头摊贩的安全教育与监管，杜绝此类高风险操作，保障公共安全。
