Description

Fire self-service rescue device

technical field

The utility model relates to the field of lifesaving devices, in particular to a fire self-service lifesaving device.

Background technique

In recent years, there have been more and more accidents where people lost their lives due to fires in our country. Especially with the progress of society, people have paid more and more attention to the destructive power of fires. Just like some time ago, tourists from mainland China lost their lives due to a bus fire in Taiwan. After investigation, many people were not killed by fire, but by smoke.

When a fire breaks out, the cause of death of most of the victims is suffocation or poisoning caused by inhalation of smoke or toxic gases. We often use wet towels to block the mouth and nose when escaping, but wet towels can only block part of the smoke. The filtering effect is minimal, and it often happens that the smoke is so thick that it is difficult to locate the rescue object.

In order to better provide people with a self-help life-saving device, reduce the casualty rate in accidental fires and increase people's self-rescue function.
