Asbestos in aircraft
Asbestos in aircraft, prior to the 1980’s asbestos in aircraft can be friable asbestos products are generally quite loose and, when dry, can be crumbled into fine material or dust with very light pressure, such as crushing with your hand. These products usually contain high levels of asbestos (up to 100% in some cases), which is loosely held in the product so that the asbestos fibres are easily released into the air.
If disturbed, friable asbestos products are dangerous because the asbestos fibers can get into the air very easily, and may be inhaled by people living or working in the area asbestos in the aircraft can be found in several aircraft components:
- Engine and electrical insulation
- Asbestos blankets, brakes
- Cockpit heating system
- Heat shields for engines
- Torque valves, gaskets
- Electrical wiring and insulation
- Cargo bays booths
Civilian and military aircraft mechanics who serviced aircraft’s would be exposed to asbestos dust, aircraft mechanics’ exposure to asbestos was usually the result of direct handling of components during routine repair. Asbestos was used in a number of parts for its heat and friction resistance.
However repairing brakes gave mechanics the greatest risk of exposure to asbestos, because prior to the 1970’s these brakes were manufactured with asbestos. The replacement of brake pads consists of constant manipulation and tugging back and forth, which most likely exposed workers to airborne asbestos fibers. The collection of fibers, over time, can lead to asbestos-related illnesses.
Asbestos management plan for aircraft’s
Asbestos exposure due to the many ACMs (Asbestos-Containing Materials) used in this aspect of aircraft construction. Where asbestos is found within the aircraft an asbestos management plan should outline emergency procedures, what to do and who to contact, along with a risk assessment, asbestos air monitoring plan and asbestos sampling procedures.
