Gas fireplaces have become popular in recent years. This article presents the first reported case of a burn injury from contact with the glass front of a gas fireplace. An investigation of the surface temperature of the glass fronts of gas fireplaces was undertaken to clarify the risks posed by these units. Surface temperature measurements of the glass fronts of 3 common gas fireplace models were obtained using a thermocouple probe. Glass temperatures reached 200 degrees C within 6.5 minutes of ignition, climbing to 245 degrees C at 14 minutes after ignition. Glass temperature continued to rise beyond this point, but it could not be monitored because the adhesives securing the thermocouple probe melted. Glass temperatures of 50 degrees C were recorded at 30 minutes after the unit was shut off. The temperatures of the glass fronts of glass fireplaces are sufficient to cause cutaneous burns within seconds of contact both while the fireplace is in use and up to one half hour after it has been turned off. Current industry safety standards are not directed at the prevention of contact burns. We recommend that (1) mechanical guards be installed to create a barrier in front of the glass; (2) strict warning labels be applied to the units and ignition switches; and (3) burn prevention information be distributed with the owner's manual for these products.
燃气壁炉近年来越来越受欢迎。本文介绍了首例因接触燃气壁炉玻璃面板而导致烧伤的报告病例。为了阐明这些装置带来的风险,对燃气壁炉玻璃面板的表面温度进行了调查。使用热电偶探头对3种常见燃气壁炉型号的玻璃面板进行了表面温度测量。点火后6.5分钟内玻璃温度达到200摄氏度,点火后14分钟升至245摄氏度。此后玻璃温度继续上升,但由于固定热电偶探头的粘合剂熔化,无法继续监测。设备关闭30分钟后,记录到玻璃温度为50摄氏度。燃气壁炉玻璃面板的温度足以在使用壁炉期间以及关闭后长达半小时内,接触数秒就导致皮肤烧伤。当前的行业安全标准并未针对预防接触性烧伤。我们建议:(1)安装机械防护装置,在玻璃前形成屏障;(2)在设备和点火开关上张贴严格的警告标签;(3)随这些产品的用户手册分发烧伤预防信息。
