Aerotoxic Syndrome : A new occupational disease?

Background

Concerns related to adverse health effects experienced by aircrew exposed to aircraft contaminated air have been ongoing for over 6 decades.

Unfiltered breathing air is supplied to the cabin via the engine compressor. The likelihood that oil leaking over the engine oil seals may enter the cabin air supply has prompted continuing debate about the hazards associated with exposure to neurotoxic substances and to the thermally degraded or pyrolysed mixture.

In this study, we undertook an in-depth investigation of aircrew involved in suspected aircraft contaminated air events.

Methods

Two studies were conducted to review the circumstances and symptoms of a cohort of aircrew working in the pressurized air environment of aircraft. A table of effects was then used for categorizing symptoms and reviewing other sources of data related to aircraft fluids and selected other conditions.

Results

Both acute and chronic exposures to neurotoxic and a wide range of thermally degraded substances were confirmed, along with a clear pattern of acute and chronic adverse effects. The latter were supported by medical findings and diagnoses, notably involving the neurological, neurobehavioural and respiratory systems.

Conclusion

A clear cause and effect relationship has been identified linking the symptoms, diagnoses and findings to the occupational environment. Recognition of this new occupational disorder and a clear medical investigation protocol are urgently needed.

Engine bearing oil leak on compressor blades in CFM56-7 engine on a Boeing 737. This oil leak was within acceptable manufacturer limits and this engine is still fully serviceable.
Yep we know the Irish Air Corps don’t have any 737 aircraft but this Boeing Aircraft Maintenance Manual shows engine bearing compressor oil leaks are routine and don’t necessarily cause the engine to become U/S.

Irish Air Corps Toxic Chemical List Updated

We are curently updating our chemical listings. There were and are a very large number of chemical substances in use in the Irish Air Corps and amost all of these substances have ingredient chemicals.

For example, the corrosion inhibiter Mastinox 6856k, which many personnel used without any PPE,  contains the below constituent chemicals. Among the ingredients include carcinogens, mutagens, immune sensitisers, irritants and just plain old toxic chemicals.

  • Strontium Chromate
  • Barium Chromate
  • Xylene
  • Toluene
  • Ethylbenzene

By following the links below you will arrive at tables showing the individual chemical names that we have extracted from some MSDS. Due to a recent Supreme Court ruling the list of chemicals is expected to grow. It is our intention to eventually create a database that links the MSDS to the individual constituents.

Bear the following in mind when using the table.
  • You can limit the number of entries you want to see
  • You can search for names such as “Tolouene” or “chromate”
  • You can sort by name, carcinogen, mutagen, reprotoxic etc.
  • Clicking on the name will take you to the Wikipedia page for that chemical
  • Clicking on the ECHA link for a chemical will take you to the European Chemicals Agency where you can look at the hazards in detail and view CAS number etc.
  • The tables do SCROLL sideways, the scroll bar is at the bottom of each table.
