After my post I remembered this article that I read recently which actually made me think about air quality. I have attached it for your reading. I could not find an English copy. For those that cant read French the very short version is that this 26 year old diver now has the mental ability of a 2-4year old after breathing bad air.

Un plongeur poursuit pour 2,3 millions $

Richard Hénault
Le Soleil
Un plongeur de 26 ans dont la vie a été totalement brisée par l'inhalation durant deux heures du monoxyde de carbone contenu dans ses bonbonnes intente une poursuite de 2,3 millions $ contre ceux qu'il considère responsables de ses handicaps irréversibles.
Affecté d'une incapacité permanente de 100 %, François Isabelle, de Val-Bélair, demeurera incapable d'effectuer quelque travail que ce soit. Auparavant sportif de calibre presque olympique et doté d'une intelligence supérieure, suivant la description qu'en fait son avocat, le jeune homme est maintenant physiquement et mentalement limité.

Dans son action déposée en Cour supérieure, le demandeur tient responsables Plongée sous-marine Nautilus, une entreprise de Québec spécialisée dans la vente et la location d'équipement de plongée sous-marine, et Envirolab, une entreprise de Sainte-Foy spécialisée dans l'analyse environnementale. Les faits allégués remontent à septembre 1999.

À cette époque, on embauchait des plongeurs pour décontaminer le lit de la rivière Jacques-Cartier. Les bouteilles d'air comprimé utilisées par les plongeurs étaient louées de Plongée sous-marine Nautilus, qui les remplissait à l'aide d'un compresseur à essence. Pour sa part, Envirolab fournissait un certificat d'analyse de l'air comprimé, d'après la déclaration du demandeur.

Au terme de sa première plongée, le 9 septembre, François Isabelle est sorti de
l'eau en toussant violemment et en vomissant. Il a de la difficulté à rester debout
et il a plusieurs pertes de conscience.

À l'hôpital de la base de Valcartier, où on doit le transporter, il reçoit de l'oxygène
pur. On doit toutefois le transférer à l'hôpital Sacré-Cœur, de Montréal, pour
recevoir des traitements en chambre hyperbare.

Par la suite, son état de santé ne cesse toutefois de se détériorer. Il a des
problèmes croissants de mémoire et de concentration, de la difficulté à parler et à
manger ainsi que de fréquents spasmes et tremblements. De nombreuses périodes
d'absence de 15 à 20 minutes le rendent « intellectuellement inopérant ».

Les tests sanguins révèlent qu'il a dans son sang un taux de carboxyhémoglobine
de 29 % alors qu'il n'aurait pas dû y en avoir. Les inspecteurs de la CSST
mesurent d'ailleurs que les bonbonnes du demandeur contenaient entre 17 et 51
parties par million de monoxyde de carbone, soit dix fois la limite permise.

Depuis lors, différents problèmes de santé, surtout de nature neuropsychologique,
ont fait basculer la vie de François Isabelle vers le cauchemar et il ne s'en
remettra jamais, relate-t-on dans sa déclaration. Il a subi une atteinte sévère de
la mémoire et un ralentissement psychomoteur important l'affecte de manière
irrévocable. Sa mémoire globale, ajoute-t-on, se situe au niveau de la déficience
intellectuelle et sa mémoire vive est l'équivalent de celle d'un enfant de deux ans
et demi à quatre ans.

Il est à tout jamais devenu un fardeau pour sa conjointe et pour la société, est-il
décrit dans sa déclaration. Malgré son atteinte neurologique grave, le jeune
homme demeure pleinement conscient de l'énorme dégradation de son état et de
sa vie.

Selon les procureurs du résidant de Val-Bélair, la faute de Plongée sous-marine
Nautilus a été d'installer la prise d'air pur à 1,6 mètre au-dessus du compresseur
utilisé pour remplir les bouteilles des plongeurs. Cette hauteur, allègue-t-on, était
insuffisante pour éviter que l'air soit contaminé par les gaz issus de la combustion
interne du compresseur à essence.

Les tests effectués par les enquêteurs de la CSST auraient démontré qu'une prise
d'air située à cette hauteur permet que soient introduites dans les bonbonnes
d'air comprimé jusqu'à 28 parties par million. Or, la norme acceptable s'élève à
cinq parties par million.

Quant à Envirolab, le demandeur lui reproche d'avoir produit sans vérification un
certificat d'analyse d'air comprimé respirable. Toujours d'après les allégations de
l'ancien plongeur et de ses procureurs, l'ingénieur qui a produit le rapport pour
Envirolab ignorait la provenance de l'échantillon qui lui avait été remis pour
émettre son opinion et donner son aval à l'utilisation d'un compresseur d'air
comprimé.

A diver continues for $2,3 million Suit

Richard Hénault the Sun

A 26 year old diver whose life was completely broken by the inhalation during two hours of carbon monoxide contained in its bottles brings a continuation of $2,3 million lawsuit against those which it considers responsible for his irreversible handicaps.

Affected by a permanent disability of 100 %, François Isabelle, of Valley-Bélair, will remain unable to carry out some work that it is. Previously sporting of gauge almost Olympic and equipped with a higher intelligence, according to description that in fact its lawyer, the young man is now physically and mentally limited. In his action deposited in higher Court, the applicant holds responsible underwater Plongée Nautilus, a company of Quebec specialized in the sale and the hiring of equipment of deep-sea diving, and Envirolab, a Sainte-Foy company specialized in the environmental analysis. The pled facts go back to September 1999. At that time, one engaged plungers to decontaminate the bed of the Jacques-Cartier river. The cylinders of compressed air used by the plungers were rented of deep-sea Diving Nautilus, which filled them using a compressor with gasoline. For its part, Envirolab provided a certificate of analysis of the compressed air, according to the declaration of the applicant. At the end of his first diving, September 9, François Isabelle left water while coughing violently and while vomitting. He has difficulty in remain upright and he has several losses of conscience. At the hospital of the base of Valcartier, where one must transport it, it receives pure oxygen. One must however transfer it to the Crowned-C.ur hospital, of Montreal, to receive treatments in room hyperbare. Thereafter, its health does not cease however worsening. It has increasing problems of memory and concentration, difficulty in speak and eat as well as frequent spasms and tremors. Many periods of absence from 15 to 20 minutes make it "intellectually inoperative". The blood tests reveal that it has in its blood a rate of carboxyhaemoglobin of 29 % there whereas it should not have had. The inspectors of the CSST measure besides that the bottles of the applicant contained between 17 and 51 parts per million of carbon monoxide, that is to say ten times the allowed limit. Since then, various problems of health, especially of neuropsychological nature, made rock the life of François Isabelle towards the nightmare and it will never go back from there, reports one in his declaration. It underwent a severe attack of the memory and a significant psychomotor deceleration affects it in an irrevocable way. Its total memory, adds one, is at the level of intellectual deficiency and its read-write memory is the equivalent of that of a two year old child and half at four years. It forever became a burden for its joint and for the company, it is describes in its declaration. In spite of its neurological attack engraves, the young man remains fully conscious of the enormous degradation of his state and his life. According to prosecutors' of the resident of Valley-Bélair, the fault of deep-sea Diving Nautilus was to install the pure air intake with 1,6 meter above the compressor used to fill the bottles of the plungers. This height, pleads one, was insufficient to prevent that the air is contaminated by gases resulting from the internal combustion of the compressor with gasoline. The tests carried out by the investigators of the CSST would have shown that an air intake located at this height allows which are introduced into the bottles of compressed air up to 28 parts per million. However, the acceptable standard rises with five parts per million. As for Envirolab, the applicant reproaches him for having produced without checking a certificate of analysis of respirable compressed air. Always according to the allegations of the old plunger and his prosecutors, the engineer who produced the report/ratio for Envirolab was unaware of the source of the sample which had been given to him to emit its opinion and to give its downstream to the use of a compressor of compressed air.

This guy used contaminated air from a gasoline compressor... I don't think this is a problem most of us have to worry about.
 
We seem to agree that diving is "safe" if you are well trained and have proper and well maintained equiptment. Airline pilots are well trained and have proper and well maintained equiptment. They still fly into mountains.

Most of the "sports" we have used for comparison don't punish a mistake with death. A poor bowler, golfer or basketball player may get hurt, but the don't die 240 seconds after their mistake.

Anything that kills you as opposed to injuring you after a mistake, lapse of judgment, or equiptment failure is dangerous. The most we can do is be well trained and equipted and keep the risk acceptable when compared with the enjoyment we get from diving.:)

Well, OK then Capt....but why wouldn't you dive with me .................<snip>... Recognizing that doesn't make me a dangerous diver.:(

I agree, but if someone IS a 'dangerous diver', what is the solution?

Take them diving!!
Talk to them
See what their problems are
Offer advice
Practise skills together
Take them diving again...and again
Talk to them...etc.

Scuba diving needn't be dangerous for anyone if we all look after each other.

It's obvious that the people that have responded in this thread think about safety and practice good diving habits. I'd dive with any of you. Next dive wear a red carantion on your suit so I can recognize you and buddy up. I'm the one that looks like a manatee.:D
 
wht is actually the thrill of cave diving and going inside a wreck ?? thats seems to be multiplying your chances of dying underwater.

BTW what is MUCK DIVING ???????????

Using the Google translation engine - its not exactly what your french professor would accept but you get the point:

Muck diving is term coined in Papua New Guinea to describe the diving to be had under a liveboard boat while it is anchored. Usually in a protected inlet somewhere, the water underneath the boat is shallow & the bottom is either silt, sand, dead coral or clumps of dirty coral on a silty bottom. The visibility is almost always limited. Muck diving can also done from the shore.

You'll find odd critters in muck that you won't see elsewhere.

Best regards.
