Toxic Fumes on Planes Blamed for Deaths of Pilots and Crew

For what it's worth, there is a very high number of harmful ultrafine particles in the air whenever a flight is taking off or landing, and also on the ground at the terminal. Most cases of exposure are just not acutely damaging to someone with normal lung function, but the damage absolutely accumulates. The heart in particular is no less sensitive to them than the lungs.

100% outside of those with electric compressors for bleed air. You can smell it with your nose on takeoff and landing.

> but not with the actual toxic fumes?

3M 8577 has a bonus carbon layer for this purpose. Its protection is not complete, but can limit the damage. You should also carry spares in case the carbon layer is exhausted.

OP has no idea what he's talking about. Passengers masks are for depressurisation events and oxygen supplies last 15 minutes - enough time for the pilots to descend. Pilots have a separate longer lasting oxygen supply. In many (most older?) planes, a single passenger activating their mask will activate the chemical based oxygen supply that feeds all passenger masks.

An N95 is fairly ineffective against oil-based contaminants.
