A fire in space is a very dangerous situation because the space environment is very different from the Earth environment, there is no air, no gravity, and there is not enough water. In the event of a fire, astronauts must take immediate action to protect their lives.
First, astronauts must immediately put on breathing apparatus and look for escape routes. Since there may be toxic fumes inside the capsule, astronauts must leave the capsule as soon as possible. If there is a fire extinguisher in the capsule, a fire extinguisher should be used as soon as possible to extinguish the flames. If a fire extinguisher is not available, water or a damp cloth can be used to extinguish the flames.
During the escape process, the astronaut must remain calm and not panic. They should keep breathing as much as possible and find a safe place to shelter as soon as possible. If it is not possible to escape, you should try to find a sealed area to keep smoke and flames out.
In space, the method of extinguishing fires is also different from that on Earth. Due to the lack of air and water, space fire extinguishers often use a substance called "fluorohydrocarbons" to extinguish fires. This substance can extinguish the flame without oxygen and does not produce harmful smoke.
In addition to using fire extinguishers, astronauts should take other measures to prevent fires from occurring. For example, they should regularly inspect the equipment and wires inside the capsule to make sure they are not damaged or overheated. In addition, they should also be careful not to litter the capsule with flammable items such as paper or cloth. In general, a fire in space is a very dangerous situation that requires swift and decisive action to protect the lives of astronauts. Therefore, astronauts must be professionally trained to be able to take the right actions quickly and accurately in the event of an emergency.
