Engine oil fumes sometimes contaminate the aircraft air supply system on commercial and military aircraft (with the exception of the B787), exposing passengers and crewmembers to toxic compounds. Many of the oil fume events reported to AFA-CWA are detectable upon boarding or taxi out, but crewmembers are not trained to either recognize or respond to odors or fumes that may contain toxic engine oil. Help to protect yourself by reading and remembering THESE TIPS to better recognize and respond to onboard smoke/fumes.

IFALPA publishes Cabin Air Quality position statement (June 27, 2013): The International Federation of Airline Pilots’ Associations again emphasizes the potential flight safety hazards posed by inflight exposure to smoke/fire/fumes, and recommends that flight crews are provided with equipment and training to ensure that smoke/fire/fumes are detected and mitigated.

 

Investigative news story (Dutch news: Zembla): Aired May 9, 2013, investigates reports of compromised flight safety/ill health reported by crews and largely denied by airlines.

 

Published review of fume events at one major US airline: Review includes description of impact of exposure to smoke/fumes on crew health and flight safety.

 

Videos that describe how aircraft engine “bleed air” can be contaminated with oil smoke/fumes - Part 1, Part 2, Part 3, Part 4: Educational tool created by Austin Byrd at the Tennessee Technology Center of Memphis (aviation maintenance school).

 

IFALPA publishes Cabin Air Quality Briefing Leaflet (Jan.10, 2013): The International Federation of Airline Pilots’ Associations acknowledges that inhaling oil fumes inflight can cause crew impairment/incapacitation which can impair safety of flight, that fumes (odor) need not be accompanied by smoke/mist to be problematic, and that crews risk olfactory fatigue, and that pilots should don oxygen immediately if they suspect exposure.

 

International Transport Workers’ Federation educational film: The ITF is a global organization with 690 member unions representing over 4.5 million transport workers in 153 countries, including AFA-CWA. “Contaminated Air: What You Need to Know” was released on July 28, 2012 to help educate airline workers about the potential for exposure to oil fumes on aircraft, including practical steps to take if fumes exposure is either suspected or confirmed

 

THINK YOU HAVE BEEN EXPOSED TO OIL FUMES/SMOKE/MIST ON AN AIRCRAFT?

 

(Note: Prof. Clem Furlong at the University of Washington (UW) in Seattle can no longer accept blood samples from crews/passengers exposed to engine oil fumes because of time/storage/funding limitations, but the research team he leads is still working to develop a suitable blood test to determine exposure to aviation engine oil additives.)

 

Prof. Mohamed Abou-Donia at Duke University is developing a blood test intended to provide objective evidence of brain damage. The test is not specific to toxic exposures, but still may be helpful. More information here.

 

SICK FROM EXPOSURE TO OIL FUMES?  Print this two-page summary version health care providers’ guide and take it to any related medical appointments, along with the MSDS of the oil or hydraulic fluid you were exposed to (ask your MEC or contact AFA-International). The guide is intended to provide doctors with information on how oil can contaminate the aircraft air supply, the associated health effects, recommended medical work ups, and possible treatments. This publication was funded by the Federal Aviation Administration. The lead author is an occupational physician and the information is well-referenced. Complete copy of health care providers’ guide here. Also, AFA-CWA bulletin describing what your doctor should know.

 

GCAQE  The primary purpose of the GCAQE is to effect the changes in the aviation industry that are necessary to prevent crewmembers and passengers from being exposed to oil and hydraulic fluid in the ventilation air supplied to the cabin and flight deck. AFA-CWA is a member. Find out why your union should join. Next annual meeting in London, England scheduled for Mar. 31 – Apr. 2, 2014. Contact admin@gcaqe.org for more details.

DOES YOUR AIRLINE USE BP2380 ENGINE OIL? All aviation engine oils applied on the US fleet contain 1-5% neurotoxic tricresylphosphates (TCPs), however this article published in 1989 reported that when Exxon 2380 engine oil (now marketed as BP2380) was heated to temperatures above 350ºC, high levels of an especially potent neurotoxin, TMPP (trimethylolpropane phosphate) were generated. So much so that the research team recommended that Exxon 2380 be banned from the US Naval fleet. (TMPP exposure has been associated with neurological symptoms, including seizures.) But this same oil is still used on US commercial aircraft! Another article reported TMPP formation at even lower temperatures (250ºC), well within the temperatures of an operating aircraft engine. AFA acknowledges GCAQE Lead Researcher, S. Michaelis for this information. As of this writing (June 2010), we are told that Mesaba and Mesa use BP2380. Less toxic oils are under development. Encourage your airline to investigate them.

 

More practical advice on what to do if exposed to contaminated aircraft air:

As you can read about on this page, the air you breathe in the aircraft cabin is supplied from the engines or APU and sometimes it gets contaminated with engine oils or hydraulic fluids that get heated to very high temperatures, often appearing as a smelly haze or smoke (but sometimes you won’t smell or see anything). This haze/smoke is a toxic soup and can contain carbon monoxide gas as well as chemicals that can damage your nervous system called tricresylphosphates (TCPs). Exposure to TCPs can initially cause stomach ache and muscle weakness, followed by delayed memory loss, tremors, confusion, and many other symptoms.

Print this information packet for practical advice on what to do if your symptoms may be caused by breathing contaminated aircraft air. Use the checklist for steps to take to protect yourself, report events to the pilot and your airline, ask AFA what product(s) are used on that aircraft type and get a copy of the Material Safety Data Sheet for your doctor to read, and give your doctor the necessary background information found in the AFA information packet.  Products that you can be exposed to include Mobil Jet Oil II, Mobil Jet Oil 254, Mobil Jet Oil 291, Skydrol500B, Exxon/BP 25/2197/2380/2389, Royco 808, and Chevron Hyjet. Get the specifics for your flight from AFA. Also, keep in mind that it is in the interest of the manufacturers to downplay any hazards on these data sheets (see Aug 2004, below). Make sure your doctor understands the potential for acute and chronic symptoms, even with low-level exposures.

Also, bring the Health Care Providers’ guide (posted above under “Sick From Exposure..”) to any doctor’s appointment. This document is intended to educate your doctor on the potential for exposure to oil/hydraulic fluid fumes on aircraft, and literature regarding symptoms associated with exposure to such fumes.

For incidents on US-registered aircraft, search the FAA Service Difficulty website to find out if an airline reported a smoke/fumes incident to the FAA. You will need the incident date and either the operator designator code or the aircraft number.

 

If you are an AFA member, notify your LEC/MEC AFA safety representative about air quality problems on a flight, and send your union representative a copy of the documentation.

March 2009: ASHRAE President sent this letter to the heads of FAA and its European counterpart, EASA, urging the two agencies to investigate and determine the requirements for bleed air monitoring and solutions to prevent bleed air contamination with engine oil. This action was unanimously approved by members of the ASHRAE Aircraft Air Quality committee (SSPC-161P) in attendance at the Jan. 2009 meeting

Sept 2008: Australian aviation regulator, CASA, has convened an independent Expert Panel on Aircraft Air Quality (EPAAQ). The EPAAQ has a broad mandate, covering both safety and occupational health and safety matters. The panel will review the evidence and prepare a report with recommendations. The report is expected to be delivered by the first quarter of 2010.  The CASA website states that “Individuals and groups representing aircrew members have raised concerns about the possibility of low level chronic exposure to contaminants in aircraft cabin air leading to potential long term health effects. Some flight crew have reported a variety of symptoms that they have associated with cabin air quality. The evidence based relationship between cabin air exposures (either in normal operations or following incidents) and ill health in aircraft crews has been difficult to ascertain. The expert panel will: review existing literature on cabin air quality; seek submissions from interested parties who wish to provide evidence for consideration by the panel; and review the evidence and submissions and prepare a report with recommendations.“

 

Dec. 2007: At long last, the ASHRAE Aircraft Air Quality Standard 161-2007 has been published. It is a voluntary standard, but represents the best consensus between industry and crewmember unions, and it includes provisions to prevent hot cabin conditions, limit exposure to oil fumes and pesticides, require gaspers in crew work areas, and more. Read about the highlights. Email AFA with any questions.

March 2006: Swiss Transportation Safety Board incident report concludes that exposure to oil fumes compromised ability of the copilot during approach and landing, that the captain had not donned his oxygen mask, and that the aircraft had a history of odors/fumes that had not been addressed.

 

Aug 2005: OSHA succumbs to pressure to settle case with ExxonMobil (see Aug 2004). Crewmembers and their doctors need to understand that the current "warnings" that ExxonMobil has published ignore the health risks associated with inhalation of engine oils and ignore the toxicity of meta and para isomers of the neurotoxic tricresylphosphates. Bottom line: if you are a hen, drink large volumes of engine oil, and are only worried about short-term effects to your peripheral nervous system, then the current warnings on the ExxonMobil labels and data sheets are okay.

 

Aug 2004: OSHA cites engine oil manufacturer Crewmembers and passengers can suffer neurological damage after exposure to aerosolized oil mists in the cabin and cockpit of commercial aircraft. In Feb 2004, AFA filed a complaint with OSHA, stating that ExxonMobil had, without basis, watered down the warnings about nervous system damage on the labels and Material Safety Data Sheets of its jet engine oils. ExxonMobil was relying on research that was incomplete and irrelevant to the exposure conditions and symptoms experienced by crewmembers and passengers.

 

June 2004: FAA acknowledges that exposure to pyrolyzed engine oil can cause impairment of the operational skills and abilities of the flightcrew, which could result in reduced controllability of the airplane.” Policy applies to BAe146 aircraft, but all commercial aircraft have bleed air system and all use chemically similar oils
