Fire cases, the statistics show that most fire casualties are caused by smoke, which affected the harm of smoking directly lethal in more than 60 percent, so can not have a emergency respirator can at the time of the fire, to avoid inhalation of toxic fumes. And now most of the equipment is equipped with a gas mask, but its protective capacity, after all, limited. The most effective fire breathing apparatus is the best choice for me. He had a direct supply of oxygen, without worrying about the inhalation of toxic gases. This portable respirator is small in appearance, easy to operate and quickly wear for a few seconds.
