Cabin Air Quality

Recently, there has been a surge in members seeking help and information related to cabin fume events.

There are 2 types of fume events: The first is low, chronic exposure, each time the engines start up or change speed on aircraft that draw cabin air from the engines. These are under-reported because they’re often not noticeable, but still negatively affect our health. The second type, and the one we are more familiar with, is an acute fume event which occurs when there is a mechanical problem that allows a more significant amount of engine oil or hydraulic fluid into the cabin air supply system. This is what commonly gets reported as a ‘dirty sock’ or “gym-bag” or “acrid” smell in the cabin.

Your Union is here to advocate for your health and safety and is available to offer support if you experience or have ever experienced a fume event. Please email or click HERE for a copy of the information provided by the union. There is an automatic response on this email that will give you all the necessary medical information for your doctor and the reporting steps to follow.

Some members have reported that the company provides a FAQ document to crews who experience fume events. It is the Union’s firm position that this document contains many errors and omissions in fact. If you have received this FAQ document, please contact us.
