You can’t smoke e-cigarettes on planes. The engine room is a narrow, closed hyperbaric oxygen chamber. The air is recycled, giving off a lot of smoke and harmful second-hand smoke, which seriously affects the physical and mental health of passengers around.
In addition, e-cigarettes contain inflammable and explosive materials such as batteries and soot, leading to major safety risks such as battery explosion, liquid penetration and high temperature conduction. Once accidentally fire, the consequences will be unimaginable.
E-cigarettes and other cigarette products are strictly prohibited in civil aircraft, apron area and terminal of the airport, and flammable materials are prohibited from entering these areas. Smoking passengers are requested to designate smoking areas in front of the terminal.
When e-cigarettes heat up the liquid, they pass through an atomizer to produce aerosols, which are colloids formed from small solid or liquid particles suspended in the air. Objects range in size from 0.001 to 100 microns. The substance contains a complex chemical composition and is a new source of air pollution.
Second-hand aerosols produced by e-cigarettes can increase PM1.0 values by 14-40 times and PM2.5 values by 6-86 times. The World Health Organization warns that when the aerosol is present in high enough concentrations, it poses a serious threat to human health, especially those suffering from respiratory diseases.
