A long time ago, in a galaxy far far awayÉÉ.I was trained to stand to the side of the regulator, not right in front, when opening the cylinder valve. Still do!

Long ago, when I was taking welding lessons, the instructor taught us to avert our faces from the regulator gauges when opening a gas tank because of a possible defect in the regulator that would pressurize the gauge and explode the glass.
Since that time, I have read several books on laboratory practices and do not recall any of them alluding to the practice of averting oneÕs face when opening a gas cylinder. Should they?
With all the accumulated experience in this group, has anyone heard of this practice or hazard?
(Note: My old instructor might have been confusing a defective regulator hazard with the one resulting from using a contaminated regulator with an oxygen cylinder.)
Thank you very much,
Ben
