Buy a small stove these days and it is likely to come covered in dire warnings about the risk of carbon monoxide (CO) poisoning and that you must not use the stove in any sort of confined space. And yet walkers have been using small stoves inside their tent vestibules in bad weather for many, many years with very few instances of trouble. What is the risk, why are all those warnings there, and how seriously should we take them?

Part 4 of this article series covers the laboratory testing of a range of alcohol stoves. This article seeks to find if carbon monoxide emissions are more problematic with alcohol stoves than with other stove types and specifically to discover the design elements that influence carbon monoxide emission in alcohol stoves.
