The heat insulation hood is a fire protection article which can cover the whole head and neck of a firefighter, the front end and the rear end of the hood should extend to the front chest and the back, and the heat insulation hood is a fire protection article for isolating high temperature and protecting the head, the face and the neck of the firefighter.
At present, a heat insulation hood used by a firefighter can only meet the fireproof heat insulation requirement, and when the firefighter is used, the firefighter can only carry a respirator and a breathing mask which are matched with the heat insulation hood, and after firefighter equipment is completed, the firefighter enters a fire scene and has to rescue in the time range that the respirator can provide oxygen;
if the fire cannot be completed, the fire must leave the fire before oxygen stops, and the internal environment of the fire is changeable, the firefighter cannot predict whether the environment of the fire changes in advance;
if the fire-fighting equipment cannot know in advance, whether the evacuation road has falling or collapsed combustion objects when the flame burns or not, and meanwhile, facing a complex fire scene environment, the fire fighter can get lost under the blocking of dense smoke;
therefore, the conditions mentioned above all cause the fire fighter to stay in the fire for too long, so that the fire fighter cannot evacuate the fire before oxygen stops, and the fire fighter is at risk;
meanwhile, the current heat insulation hood cannot provide oxygen respiration for trapped people, when trapped people are found in the rescue process, because the carried respirator and mask and the heat insulation hood only can only maintain the use requirement of firefighters, because the firefighters need to rescue the trapped people under the premise of guaranteeing the safety of the firefighters, if the firefighters equip the respirator and the like with the trapped people, the safety of the firefighters are likely to be affected, and the firefighters and the trapped people are trapped in a fire scene, so that how to provide temporary oxygen respiration for the trapped people is a problem which is continuously solved at present.
