When an avalanche comes, we may not have time to send a danger signal to the outside world, because the avalanche may instantly cover the skiers. Therefore, it is very important for skiers to send rescue signals to the outside world in time. At critical moments, avalanche signal gloves can play an important role in sending rescue signals. If there is an avalanche while skiing, the skier can launch the signal flare in advance. 3 seconds after launching the signal flare, the helium cylinder will be filled with helium into the SOS rescue balloon, so that an SOS rescue balloon will float in the air, helping rescuers quickly find skier buried in snow . This also speeds up the rescue. Of course, if the skier is too late to launch the signal flare and has been buried by the avalanche, the skier can find the direction of the sky through drooling. Then point the avalanche signal glove at the sky to launch the signal flare. The pneumatic device will compress the air to eject the signal and fly to the air through the ice and snow layer. After 3 seconds, the SOS rescue balloon will also unfold and float in the air, which can be quickly noticed by rescuers.
