When propane is burned, does carbon monoxide result?  I've read conflicting material, some say that it doesn't, some say that it does and some say only if the combustion is incomplete.

If it does produce CO, what measures would be sufficient to prevent poisoning?

EDIT:  I love Wikipedia!  Read http://en.wikipedia.org/wiki/Propane#Properties_and_reactions and tell me what constitutes "excess oxygen" .

Excess means there is more reagent than you may expect from stoichiometry. That in turn means you have to start with balanced reaction equation.

If you are using propane in properly built burner in a well ventilated space there is usually no CO risk.
