From all of my chemical training, a bit extensive with the chemicals we used in manufacturing and I was the safety officer and responsible for keeping the hazard sheets up to date and informing the staff of any changes and hazards, I never heard of that. Also it does not make sense, but that does not necessarily have to be a factor in what it really does.</p> <p>The safety officer at CBS when we got in the heliarc equipment said it was totally harmless, especially if we kept the door open. I thought that a slight contradiction at the time. But it could be true, as long as the door was open it could not build up and exclude oxygen.</p> <hr /><a name="a5674_19"></a><p><b>From: Jer (DIAMOND)</b> [<a href="lmessages.php?webtag=EE&msg=5674.19">#19</a>]<br /> 9 Jan 2007<br /><b>To: Harvey only (HARVEY-ONLY)</b> [<a href="lmessages.php?webtag=EE&msg=5674.18">#18</a>] 10 Jan 2007</p> I believe that in a shop, with what I would consider small amounts in cylinders, that is coming out of a 3/8" hose there is no major risk. This would be a similar set up that would be used in a laser engraver. I also believe what our safety dept. says about one breath of 100% nitrogen. My thought is nitrogen expands so quickly into the atmosphere, that a cylinder in a ventilated shop has little risk. I would guess the bigger risk with a cylinder is pressure and all the precautions need to be observed there also.<hr /><a name="a5674_20"></a><p><b>From: Dave Jones (DAVERJ)</b> [<a href="lmessages.php?webtag=EE&msg=5674.20">#20</a>]<br /> 10 Jan 2007<br /><b>To: Jer (DIAMOND)</b> [<a href="lmessages.php?webtag=EE&msg=5674.19">#19</a>] 10 Jan 2007</p> Maybe they give the "one breath..." warning because there might be some yahoo working somewhere that thinks "well, inhaling helium gives funny results, I wonder what will happen if I inhale nitrogen from this hose?" <hr /><a name="a5674_21"></a><p><b>From: Jer (DIAMOND)</b> [<a href="lmessages.php?webtag=EE&msg=5674.21">#21</a>]<br /> 10 Jan 2007<br /><b>To: Dave Jones (DAVERJ)</b> [<a href="lmessages.php?webtag=EE&msg=5674.20">#20</a>] 10 Jan 2007</p> Oh No! Now I obligated to try it.
