Carbon monoxide is a highly dangerous gas that rapidly overwhelms the senses and may prove fatal. As it's odourless, colourless and tasteless, it's very hard to notice without a detector device. Using a gas detector in high-risk places makes it simple to detect and take appropriate safety measures.
