It is intended for individual protection of the respiratory organs and people's eyes from toxic combustion products (including carbon monoxide) during evacuation from smoke-filled premises during a fire and from other hazardous chemicals (vapors, gases, aerosols) in cases of technogenic accidents and terrorist acts. Time of protective action: not less than 30 min. Differences from analogues: The hood has an internal self-tensioning system for the headband, which ensures a tight fit of the half-mask to the face, regardless of the degree of tension by the user of the external headband. This design eliminates user errors, which makes it possible to use it even for unprepared people. The lateral arrangement of the self-rescuer filters does not limit the mobility of the head and neck; when the head is tilted downward, there is no leakage due to the half-mask shift. Available in 3 modifications: Basic, children's and reinforced models.
