There has been much speculation that Mobil Jet Oil II may be the cause of the alleged adverse health effects. This is unsupported by the scientific evidence … The clinical symptoms reported are not the same as those that have been historically seen for TCP. The reported symptoms appear to closely match those for exposure to carbon monoxide (CO). These effects can be exacerbated by low oxygen levels and high carbon dioxide levels in the aircraft cabin. Possible sources for carbon monoxide include the ambient cabin air and, in the case of a malfunction of the aircraft mechanical systems, thermally degraded hydraulic oil and turbine oil that might enter the aircraft cabin. These oils may break down at very high temperatures and liberate carbon monoxide on contact with hot metal surfaces. Under these extreme conditions, carbon monoxide would be produced from virtually any oil and independent of any additives, including TCP, that might be present.49
3.47 During his oral evidence to the Committee, Mr Julian Plummer, Manger of Aviation Lubricant Sales with Mobil Australia made the following comment:
Mobil do not consider accidental exposure to oil vapours in an aircraft cabin to be ‘normal use’, but the levels that can be reached are comprehended by our internal and published risk assessments and are considered safe. …
The tricresyl phosphate (TCP) additive used in jet oils provides the lubricant with improved anti-wear and load carrying capability. Its properties are unique, and no replacement has been identified which can meet the stringent performance requirements of a modern jet engine oil. Our submission details that the TCP used in jet oil II is low toxicity, about 25 to 60 times less neurotoxic than TCPs used in the 1950s. …
Our risk assessment details that it is not possible to receive a harmful dose by inhalation at the threshold limit value of five milligrams per cubic metre, which would be visible mist. It is also not possible to receive a harmful dose from accidental skin contact, and there is no record of a jet oil formulated with modern conventional TCP causing human toxicity. …
Tricresyl phosphate is present in jet oil at approximately three per cent, which is around 30,000 parts per million. The neurotoxic components are

orthoisomers which are only a small proportion of the TCP and are present at roughly 140 parts per million in the jet oil. Jet oil is neurotoxic if you drink it, and we have established doses for both a toxic one-off dose or a toxic ongoing dose, which is a smaller amount that you would have to ingest each day. Based on normal things, these would be impossible to achieve. …
The studies show that it is possible to breathe a mist. We are now talking about a mist of the oil which contains three per cent, whereas I suspect the
0.1 milligram per cubic metre that was mentioned as the NOHSC requirement – the maximum – was just TCP. I am now talking oil containing three per cent TCP. It is possible to breathe a mist at five milligrams per cubic metre, which is the accepted maximum workplace level for lubricating oils, five days a week, eight hours a day, in an ongoing sense without absorbing a toxic dose through inhalation. For dermal contact, we have established that it is possible to cover your entire body surface with the liquid for six hours and not absorb a toxic dose through the skin. Our prime warnings are against ingestion of a product. It has always been believed that more pure forms of TCP would not do the same lubricating job. It relied on the variety of molecules in there to perform the function.50
