View object in our online collection. First, a little background history. Canaries were used in mines from the late 1800s to detect gases, such as carbon monoxide. The gas is deadly to humans and canaries alike in large quantities, but canaries are much more sensitive to small amounts of the gas, and so will react more quickly than humans.

Silo/filter probes for your coal mill system. Highly combustible coal dust poses a serious hazard. CO builds up in coalfilled silos and in cyclones or bag houses that are not being used, while imprecise O2 levels in inert coal mills can also present a significant danger. In either situation, selfignition is a real possibility.
