Aircraft fire features complex precautionary measures first

As a kind of high-tech and complex-structured transportation, airplanes may cause major fires and malignant accidents if the aircraft are negligent and erroneous during operation. Aircraft fires have the characteristics of fairly rapid fire development, difficulty in evacuation, rapid smoke dispersion in the cabin, difficulty in extinguishing fires, strong fire suddenness, and severe losses caused by fires. Therefore, active research on how to prevent aircraft fires has become an urgent issue.

(1) Configure the necessary fire protection system.

First, install an automatic smoke alarm system. Because some parts of the aircraft have high temperatures and are mostly installed in small concealed places, it is not appropriate to install temperature sensing and infrared alarm devices. The smoke detector will alarm when there is smoke, you can get a signal before the fire light, and take emergency measures.

Second, install automatic fire extinguishing devices. The ultra-fine dry powder automatic fire extinguishing device is a fire fighting product with high fire extinguishing efficiency and low fire extinguishing concentration in the world today. And it is non-toxic, harmless, no damage to the ozone layer, and does not produce a greenhouse effect. No moisture absorption, no agglomeration, good fluidity, dispersibility and electrical insulation. Install such devices in the engine compartment, landing gear, fuel tank, cargo compartment, kitchen, toilet, etc. of the aircraft to reduce the number of casualties even if the first fire is extinguished.

(2) Fireproofing of shipments.

Prior to shipment, any package with signs of damage or leakage must not be loaded onto the aircraft. Strictly abide by the relevant regulations for carrying dangerous goods. When loading and unloading goods, the shipping personnel shall not smoke. Articles with inconsistent chemical properties shall be strictly classified, stacked and shipped.

(3) Fire prevention of the aircraft before and after take-off and landing.

Before take-off, the aircrew strictly inspected the aircraft's fuel capacity, cargo capacity, passenger capacity, fuel system, power supply system, electrical instruments, life-saving equipment, fire-fighting equipment, and load balance, etc. Exclude, take off without illness. After the aircraft is parked on the apron, it should be cold-turned to eliminate the fuel accumulated in the tail nozzle of the engine to prevent fire. After the aircraft entered the station, the aircraft was inspected and the accident was eliminated in time.

(4) Fire prevention of aircraft during navigation.

Strictly abide by flight regulations, strengthen the management of on-board electric heating equipment, prevent the aircraft from being struck by lightning, and strengthen the management of oxygen equipment.

Top 10 flight safety regulations

Tips: American Aircraft Safety Expert: "Top Ten Flight Safety Rules"

To "select direct flights". Statistics indicate that most air crashes occur during takeoff, descent, climb, or taxi on the runway. Reducing the number of flights will also reduce the chance of encountering a flight accident.

You should choose an aircraft with at least 30 seats or more. The larger the aircraft body, the more and more stringent international safety inspection standards, and in the event of an air accident, the survival probability of passengers on large aircraft is also relatively high.

Remember the safety instructions before takeoff. Various types of escape doors have different positions. After passengers get on the plane, they should spend a few minutes carefully listening to the safety instructions introduced by the flight attendants.

Recently, many passengers like to take large luggage with them on the plane, which is not in line with flight safety. If the aircraft encounters turbulence or an emergency occurs, the locker above the seat usually cannot withstand heavy objects, and many passengers are hit by the falling luggage and even die in the head.

Fasten your seat belts at any time. When the aircraft is overturned or encounters turbulence, tightening the seat belt can provide a more layer of protection for passengers, so as not to collide in the cabin.

When an accident occurs, you must obey the instructions of the flight attendant. After all, the primary task of the flight attendant on the plane is to maintain safety.

Do not carry dangerous goods on the plane.

High-temperature beverages such as coffee and hot tea should be served by specially trained flight attendants. If passengers take these high-temperature liquids themselves, scald accidents often occur.

Don't drink too much alcohol on the plane, because the cabin pressure in the cabin is different from the flat ground, too much alcohol will make the passengers' ability to respond to emergency situations slow down and lose their precious opportunity to escape.

Stay alert at all times. Flight safety experts point out that passengers on the plane should remain calm and leave as soon as possible under the direction of flight attendants.
