better safe than sorry
As we know on 28 March 2012 Mr. Ted Atkins , http://www.topout.co.uk/system/ who introduced to the market his oxygen mask for oxygen system, decided to connect old oxygen reducer POISK to the cylinder of GB-producing which promote to Nepal by Mr. Neil Greenwood, Director of Summit Oxygen International Limited, Mob:+44 (0)7884006610, Tel:+44 (0)1252 625802, www.summitoxygen.com. The situation is very serious and we give below the message text:

News travels fast of an accident and I would like to explain the facts as we know them today. I was injured testing a Poisk regulator in conjunction with a new Summit cylinder yesterday. I chose to use the new cylinder because it was a new introduction to climbers and it is delivered as being higher pressure than the Poisk cylinders.
The regulator that failed was not an old style nor was it the newest style. As I fastened it onto the cylinder there was an explosion. I had pieces from the gauge embedded in my neck (I am grateful to Kaju from Asian Trekking for taking this out with a pair of pliers).
Neil Greenwood of Summit Oxygen has been on the phone to me and we are trying to determine exactly what went wrong. Meantime I have sold a number of these cylinders and feel obliged to inform all of a potential problem. I recommend 3 specific precautions at this stage:
Wear ski goggles when changing the regs
Wear gloves
Put the cylinder onto the regulator keeping the regulator in the same plane with the gauge pointing at the ground
It could be that this was simply a one off defective regulator, but I have fitted so many in my time and this is a first for me and the first I have heard of. I was VERY lucky to get away with the level of injury I received so until this situation is resolved PLEASE observe the precautions I have listed. These precautions would actually be good practice in all cases involving regulator changes and I urge you to disseminate this information. I have attached some photos

Our comments:

1. It seems at least strange to say that in Summit Oxygen (SO) cylinders the pressure is higher than in POISK cylinders. It is no secret, the outside temperature make an influence on gas pressure in cylinder that is why the oxygen value determine usually in grams. Everybody know, our 4 l cylinders have no less than 1650 g oxygen (SO 1543), in 3 l cylinders no less than 1200 g ( SO - 1157 g).

2. Each reducer of POISK have its own number and take a lot of serious tests before sale (we connect and disconnect each reducer of filled cylinder 10 times, check the leakages, determine the real oxygen flow from reducer to mask etc.). After tests all reducers blow with nitrogen high purity.

3. Moreover POISK do not guaranty nobody and ever the safe connection opportunity its reducers to other cylinders. Of course nobody can forbid you to install in passenger car the engine of truck, but you have understand all possible effects of such actions.

4. In our opinion it seems very strange and dangerous such advices of safety connection our reducers to other foreign cylinders. What is the deferens if dead person will have the ski goggles or not? (find examples of oxygen cylinders explosion in web - http://www.oxygenconcentrators.org/info/oxygencylinderexplosion/, http://www.imrser.org/PDF/JMRI.2004.Colletti.pdf); http://www.atsb.gov.au/publications/investigation_reports/2008/aair/ao-2008-053.aspx, http://www.refrigeration-engineer.com/forums/showthread.php?34141-Be-careful!-In-Russia-the-oxygen-cylinder-exploded-at-the-master-refrigerator-repair

Our recommendations:

- do not use POISKs expired or illegally refilled cylinders;

- do not connect POISKs reducers to other oxygen cylinders or oxygen systems without our coordination;

- use only new reducers and cylinders which bought in POISK Ltd. with appropriate guarantees;

- every year, before use test your reducers in POISK Ltd. or in region service centers of POISK;

- if you have any doubts about the safety of reducer or cylinder, please tell us its number. We will inform you when your reducer or cylinder is made, the date of these last testing and give you recommendations for their further use.

- we recommend everybody who use the oxygen equipment especially who is responsible for sale these to customers and take a decision to sale that, look through next news more carefully:
