Have you ever installed carbon monoxide detectors in your farm buildings? If you haven’t, this may change your mind. A carbon monoxide detector or CO monitor is a devise that detects the presence of carbon monoxide (CO) gas to prevent carbon monoxide poisoning. CO is a colorless, tasteless and odorless compound produced by incomplete combustion of carbon-containing materials. It is sometimes referred to as the “silent killer” because it is virtually undetectable without using a detection devise.
