Technical Field

The invention relates to the technical field of fire fighting, in particular to a clean air guarantee system in a severe environment.

Background

After a fire occurs, a fire rescue organization should investigate the accident according to the law to find out the cause of the fire. In the investigation stage, investigators go deep into the fire scene to perform investigation, and for most building fires or underground space fires, the working environment is in a relatively closed state. In this environment, various substances are burned or decomposed by heat due to the effect of the early fire, and various complex harmful substances are generated, and these substances exist in a gas or extremely small particle state for a long time, so that the air in the environment is polluted. When the investigators work for a long time in the environment, the physical health is damaged.

Current fire investigation practices generally adopt a mode of wearing a mask or a face mask to strengthen personal protection. However, both masks and face masks increase the consumption of consumables, and they do not completely solve the risk of inhalation of toxic and harmful substances.

Therefore, the invention is necessary to provide a clean air guarantee system in a severe environment. The system can be used for fire scene investigation and various operations under other similar severe environments.
