Know CO - use an active warning carbon monoxide detector

The ATSB is urging operators and owners of piston-engine aircraft to use an active warning carbon monoxide detector. 

Carbon monoxide (CO) is a colourless and odourless gas, and its presence may not be detected until the physical symptoms and cognitive effects present themselves. 

When inhaled, CO preferentially binds to haemoglobin, the oxygen carrying molecule in red blood cells. This creates COHb compounds and prevents oxygen from binding to the molecule and being transported, resulting in oxygen starvation. Symptoms can include breathlessness, confusion, disorientation and incapacitation.
