在过去的几十年中，消防部门的任务已经发展为firefightersare the “Do It All” responders. We all know the runs I’m talking about:EMS，漏水，水救援，电线向下，卡住的电梯，奇怪的气味，气体泄漏，当然还有一氧化碳警报。这不仅仅是对火灾的反应。消防员需要在许多不同的领域熟练，我们需要在每个警报器上处于游戏的顶端。让我们专注于第一批反应消防员的一个区域。
In most areas, laws went into effect requiring carbon monoxide meters to be installed in residential and commercial structures. Of course, these laws affected the local fire departments that respond to these alarms once they activate, and, as we all know, when the low battery chirps. Fire departments across the country immediately had to purchase metering devices and train their firefighters about carbon monoxide (CO). Firefighters began learning how these meters work, but how well do you know your meter? Is it telling you all the information that you need? Some departments choose to purchase a multigas (four- or five-gas) meter. These will most likely read oxygen, carbon monoxide, hydrogen sulfide, and lower explosive limit. Other departments have chosen to purchase a single-gas meter that just reads CO. So what is the best option for your department? Are the current meters and knowledge of your firefighters enough? Will this protect your firefighters from harm? The answer: It depends. All I can say is never let your guard down and prepare for the unexpected. Wear and use all of your gear, personal protective equipment, and self-contained breathing apparatus (SCBA), and be ready for the worst.
Here are two recent events that will hopefully make you think twice about a simple CO alarm.
是0235小时。我的小队公司被分配给一家梯子公司，以回应私人房屋中的CO警报激活。直到我们到达之前，这都是每天的事件和业务。当我们在房子前拉起时，我们看到人们和一些邻居一起站在外面（有点奇怪，持续了0235小时）。当我打开设备的门时，我的单加速器co仪表令人震惊，它继续增加到85 ppm。当我们互相接近时，我还可以听到阶梯公司的官员表令人震惊。我们立即要求其他单位响应和公用事业公司，因为这不是正常的回应。我们前往不同的私人房屋进行调查和撤离。现在，我们的每个房屋都会得到300-400 ppm的读数。在调查了多个房屋之后，确定地下电线在街上燃烧。 Power was shut down to the area until it could be repaired.
最近，发动机和梯子公司被分配到波士顿市场的CO探测器激活。到达后，消防员用电表进入了该机构，以调查地下室的警报。成员在下台楼梯下行驶时正在监视他们的仪表。两个CO仪表仍在阅读0 ppm，但一名官员正在携带一个额外的仪表，氧气传感器的氧气降低降至20％，这是在仪表的警报阈值之前。消防员立即将他们的SCBA脸部碎片戴上，并要求做出危险品回应。当他们继续研究时，他们意识到检测器激活是用于二氧化碳（CO2），而不是一氧化碳（CO）。他们注意到几个较小的二氧化碳缸，然后关闭，然后离开了建筑物。一旦小队和危险品公司到达，他们进入了地下室，并带有额外的仪表，包括二氧化碳计。随着调查的继续，地下室中含有大型液体CO2的大露水，该露水泄漏并部分冷冻。缸被关闭，地下室通风。由于553：1的较大膨胀率，许多餐馆开始使用液体二氧化碳。C02被认为是不可易燃的，无色的，无味的，无味的，并且比空气重1.5倍。只能确定您的部门具有带有二氧化碳（CO2）传感器的仪表。确定问题的唯一其他方法是通过氧气的位移。发生了许多类似的事件，造成了伤害和死亡。你可以review liquid CO2 leaks that occurred in McDonald’s restaurants in Phoenix, Arizona, and Pooler, Georgia, for additional information.
