Close... but explosion is not the term I would use. The higher the oxygen content, the lower the autoignition point. Add adiabatic heat due to compression and any contaminant in a cylinder may partially combust. The most common problem with a contaminated cylinder is not conflagration, but poisoning.I believe that NetDoc concluded that a flash explosion occurred in these two incidents
Can't wait for the specifics.. A properly set up continuous blending system is actually MUCH more cost effective than PP blending. With a blending system, which you can build for under $300 with an O2 analyzer attached to it..
Not true. You can create most any 'nonstandard' mix from banked 32 and any non-standard mix from banked 40 without the problems associated with putting pure O2 into an unclean tank.
What cost is that? A t-bottle of O2? A gauge? PP blending is an 'entry level' blending system. There's nothing "full-blown" about it all and it's incredibly wasteful. With banked 40% and air you can easily top off any existing NitrOx tank without having to bleed it all the way down. Many shops here in Florida charge you by the cubic foot and not on a complete fill.Ultimately, if a shop needs to go to the cost/hassle of having a full-blown PP blending system anyway...
Force-e in WPB only does pp fills for nitrox and I think that is true with all their shops including the one in Pompano but not certain. Another shop in WPB that I use for O2 fills will do pp if you need a mix they don't bank and it will cost you more per fill.
Your safety is your primary job. Be proactive in this regard. Ask to see their operation. Ask to see their clean air certificate. Is it over six months old? How do the compressor and fill banks look? Do they have a time tracking method for their filters? Do they have replacement filters in stock? Not only do you have a right to be nosy, you owe it to your family. We own two CO analyzers and three O2 analyzers and travel with them for this very reason.
Portable gas or diesel powered compressors.... Boat fills where the fumes got sucked into the intake of the compressor.Yes perhaps the OP could provide more information on this?
