For the time being you should minimize any hazards that you feel are present by avoiding the circumstances or protection of some sort.
"Avoiding the circumstances" requires staying away from aircraft which provide bleed derived air to the cabin and flight deck. Not a viable option for flight crew, unless they fly the 787, or the classic DC-8, or a few other rare types which do not rely upon bleed air for pressurization.
As for "protection of some sort", you must either use bottled oxygen, or wear a respirator with an organic-vapor filter. For the entire time that you are in a bleed air environment. Easy!
