Inquiry (采购产品): Carbon Monoxide I am the owner of a carpet cleaning company. I just received a large account and I am using a 13 hp 12 volt propane carpet cleaner. I finished my first job today. The trouble is the Carbon Monoxide created by the Propane cleaner. What should I use to protect myself? I know I was exposd today. The machine does have a Cat converter which lowers the emissions somewhat, but I am feeling some nausea. **** Hidden Message ***** Ralph Richardson 01879 Company: Freedom Carpet Cleaning E-mail: richardson_2606@comcast.net **** Hidden Message ***** richardson_2606@comcast.net
