Where is it used?
RZK, which helps to fully protect itself, due to its significant weight and inconvenience of movement, is used mainly in areas of man-made disasters. There, firefighters and liquidators simply have no other way to protect themselves, even if only for a short time.
OZK is in service with the army, but the breadth of access and the possibility of purchase led to its use even for fishing and hunting.
"Pass", "Rescuer", "Vympel" - in service with special forces. These suits have a different focus - protection from biological, thermal and chemical influences, but for a certain time they can also protect the body (skin, mucous membranes, eyes, subject to the presence of a gas mask) from all types of particles, except for gamma.
