With the arrival of daylight savings time serving as a reminder to check things that we do not always think about, now is a good time to remind ourselves to check that our carbon monoxide detectors have good batteries and are fully functional. Carbon monoxide poisoning claims several lives each year and leaves many others with serious residual injuries. Because carbon monoxide is colorless and odorless, there is no real warning that a carbon monoxide poisoning accident has happened or is happening until it is far too late. Carbon monoxide detectors are the front line defense against these kinds of injuries, so it is worth a few minutes of your times to check to make sure that they are functioning properly.
