...and another thing. I went to a safety lecture once and the woman running it suggested we all go shopoping and buy one of those plastic bags you cook turkeys in. She demonstrated how she could put it over her head and rebreath for a good long time - long enough to walk all the way around the entire room.
She did point out though, that it needed to be a bag made to withstand temps hot enough to roast the turkey and not just an ordinary plastic bag.
