FG Fatality

I worked in an underground mine for many years, and one of the gases we worried about was CO. If there is air movement, it mixes with air and can be ventilated out. If there is little air movement it will sink to the floor. That's why CO detectors are supposed to be mounted at knee level, the height of your head while sleeping, which is when you are most vulnerable. Most ice tents have vents in the top, which would do little to help you if no one is stirring the air by moving around.
I am just putting these facts out there, people will have to make up their own minds how they want to deal with heaters in inclosed areas. I just hate reading about people dyeing while trying to have fun.
