What planet or galaxy does the wrench come form?  Can I get just the wrench?

I know I'm about to step into one of the biggest piles of dung I've 

stepped in in a long time.  so please Keep the flames to a minimum. 

Or to put it another way, don't bother, I DON'T CARE!!!!


I was thumbing through the November/December issue of Alert Diver 

(I'm behind on my reading) when I saw this "URGENT DEVICE RECALL" 

which I include here for your reading enjoyment.


>>>>

URGENT DEVICE RECALL


Important Safety Information


	Life Support Products, a brand of Allied Healthcare Products Inc., 

oxygen regulator model L270-020 has been associated with fires in six 

incidents reported over the past three years.  Divers Alert Network 

distributes this regulator in the Standard, Dual, Mini, and Training 

Oxygen Units.  Investigative reports to date indicate that the 

regulator fires reported were the result of communication 


<<<<<<<<


(Ed. Note:  I belive the word should have been contamination not 

"communication")


>>>>

(grease, oil, or a substance containing hydrocarbons) introduced into 

the regulators during maintenance or use.

	

	Immediately inspect your oxygen regulators carefully for visible 

contamination and general condition.  Any regulator not in good 

condition should be removed from service until it can be 

reconditioned or replaced.


	To improve the resistance of your regulators to the kinds of 

contamination reported, Allied is providing sintered bronze inlet 

filters.  In light of the safety concern, it is imperative that you 

change these filters.  This filter will replace the filter currently 

found within the inlet port of certain Life Support Products (LSP) 

regulators.  Because of the smaller pore size of the filter, it will 

improve filtration of the types of contamination reported.  While 

this filter will be helpful, It is by no means foolproof in 

preventing contamination.  Proper adherence to all maintenance and 

use requirements remains essential.


	Please call Allied Healthcare Customer Service at (800) 231-5273 

between 8:00 AM 5:00 PM CT for a "Fax Response" form.  A retrofit kit 

will be forwarded to you once you complete a "fax Response' form.  

The retrofit kit Includes the requested number of filter(s), new 

label(s), alien wrench, and an instruction sheet necessary to 

retrofit your existing LSP regulators.  The retrofit process requires 

about 45 seconds.


	In addition, Allied will supply you with additional Information 

about reducing the risks associated with oxygen and oxygen delivery 

equipment.  If you have any further questions or concerns, please do 

not hesitate to contact Allied Healthcare Products, Inc. or DAN 

Training at (919) 684 - 2948 ext. 555.  Please accept our apologies 

for any Inconvenience this Issue may cause you.

This brings, once again, the debate over how much of an attempt we 

need to make at O2 cleaning our gear.  When coupled with the recent 

discussion on Viton O-rings, it seemed appropriate to open this can 

of worms once again.  I know some of you have already made up your 

mind on this topic.  You are welcome to your opinion and don't need 

to read any more.  What I am about to say will only anger you or 

further support your belief.  I don't want to anger you or have 

anyone saying "Ya!!! What he said!!!".  For those of you on the 

fence, please read on.


I am NOT employed at nor do I own a dive shop.  I am a PC (Privileged 

Customer) at a dive shop.  As a certified "Gas Blender"and a PC, I do 

partial pressure gas blending at a local dive shop.  I take a great 

deal of care to insure that ALL of the air that goes into my tanks, 

and others I blend for, is O2 compatable "E" grade breathing gas or 

better.  You can bet your butt I ask to see the analisys at any shop 

I am not familure with!!  If I am not satisfied with the quality of 

gas beeing pumped I go else wher.  By doing this I insure that the 

gas I breath is clean and free of hydrocarbons.  I CLEAN MY TANKS 

ONCE A YEAR ANYWAY!!!!


As I stated in a post yesterday I also use Viton (brand hydrocarbon 

free) O-rings for every thing.  I have them I my valves, tanks, and 

regs.  I use them in my scotter (I find that they last three or more 

times longer) and some other aplications wher Viton is not usualy 

sugested.  I go top shelf with all components in my gear.  I DON'T 

HAVE GEAR FALURES.


When a customer comes in to the dive shop and asks for a nitrox or 

Tri-mix fill, both the store and I, insist that the tank be O2 

cleaned within the last year (mine are).  I have no idea wher you got 

your last fill or how many "dirty" fills you have accepted.  I am the 

one at risk!!  When I start adding pure (medical  grade) Oxygen to 

your tanks I have no way of knowing how much compressor oil is on the 

walls of your tank.  Your fill is NOT worth putting me at risk for.


For thouse of you that fill your own tanks by partial pressure 

method, do what ever you want!!!  But ask your self "is this fill 

worth injuring myself for".  You decide how clean is clean.


If you want to add to O2 your self and bring them in for the air top 

off...  GREAT that will be 5 bucks like every other air fill.  You 

have already proven that the tanks are clean enough to dilute what 

ever is in them with air.


I have never seen an O2 fire but it sounds like Allied Healthcare 

Products, Inc. beleves that it happens.  And that is enough to 

convince me.
