Peter Crawford asked the Naked Scientists:
   Chris, was listening to Ask the Naked Scientists on 26.7.13 and there was a question on Acetylene Cylinders and their safety. I  was intrigued and decided to research this myself.
Safety is the main apparent reason for its transportation upright in cylinders. Acetone could leak out through the valve if lying down and would be corrosive. It is extremely unstable and corrosive if expelled in this way. Also, the issue of heating of the cylinder in a horizontal position, risk of shearing or compression in an accident and the idea that if a flame was ejected whilst lying horizontally it was be much longer than in an upright position.
Love your show but thought I must correct this.
Thanks
