Aerotoxics in a Nutshell
Everything Concerning Toxic Cabin Air
The contaminated cabin air issue has burdened the airline transportation industry with controversy for decades. The conspiracy to hide the issue has resulted in very many illness and injury casualties and death among employees. Passengers, your customers, have also been hurt. Enough is enough. Time is now more than full enough to find ways to reduce, if not eliminate the problem.
This presentation is intended to be a working document. It provides suggestions that when refined and implemented should reduce the exposure over the entire industry. It offers an opportunity to specialists in each subject area to consider more deeply how these and new ideas can be brought to bear on the problem. It matters not how this document is perceived. It is first and foremost a one of a kind opportunity to make the industry a happier and healthier place to work and serve the public.
Subject areas are divided into seven distinct sections. Each section provides suggestions first, brief explanation, and endnotes as deemed necessary for factual support. The Sections:
Health Risk and Business Risk
Discussion of both is offered. At present these issues are seen roughly as equal and opposite. Each resides on opposite sides of a balanced lever. Keeping the balance results in stagnation; a very clear and easy to understand impasse. Imbalance represents mutual enmity. Please let us dispense with the lever.The section includes an estimate of the human exposure to toxic cabin fumes; a theme that continues throughout the document. You will find it difficult to challenge the results of these estimates.
Toxicology is discussed very briefly.
What is in synthetic turbine engine oil? This has been an elusive question since the 1950s. Perhaps the formula is no longer a proprietary issue to be withheld from public view as “industrial secret” or “intellectual property”. You will see the formulated chemicals with a notation of toxicity for each. Carbon monoxide should be considered the most immediately urgent poison to be reckoned with!
The dose – response relationship, or how inhaled toxicants manifest themselves within the human body – is discussed in lay terms but sufficient detail. The point is made that it is futile to argue for conclusive scientific evidence of cause since scientific evidence is always, by nature itself, inconclusive. Preponderance of evidence must be accepted as sufficiently conclusive in support of mitigating the aerotoxic exposure.
Engines and Air Conditioning Systems
This section follows the route of oil leakage from the engine oil reservoir through the air conditioning system. Interesting conclusions begin to build here that are further developed in section V.
Exposure to Occupants
First, a practical discussion regarding pilot awareness followed by more technical considerations of the distribution of conditioned air within the cabin and flight deck. It continues tracing the route of oil from aircraft systems into the lungs of occupants. Some surprising conclusions reside in this section that when subject to further scrutiny in chemistry laboratories, will undoubtedly lead to even more surprising conclusions. Plans are forming to pursue this additional knowledge.
Perhaps this section details causes of fear displayed by airline industry executives with respect to the contaminated air issue. It results from the author’s specific education and years of work experience in airline commercial insurance, safety and risk management. Airline board members would be especially interested in this section. They could become allies in a push to find economically acceptable ways to assist in the aerotoxic mitigation effort.
Caring for the Ill and Injured.
Opportunity for the airline industry to participate in an exciting health related effort on behalf of aircrew members and passengers is suggested in this last section. The opportunity can be managed very economically and, if trials show the promise expected, could grow to be beneficial across other segments of society.Physiologically, there appears to be no “down side” to this idea. Individuals, ill and injured casualties of fume events, who participate in the trial(s) should receive general health benefits.CONTINUE READING HERE
