Confined Space Accidents

Don't blindly rescue

When you find someone fainting in a limited space, do not blindly enter the rescue, and call 119 and 120 as soon as possible. While waiting for rescue, the forced air supply equipment can be used to forcibly supply air inward at the entrance and exit to increase the oxygen content in the limited space.

Due to the special structure of the limited space, the rescue is usually difficult, even if it is a professional rescuer, it is necessary to take the correct and effective rescue method according to the on-site situation.
