Self-Contained Breathing Apparatus （SCBA）Cylinder

The self-contained breathing apparatus (SCBA) is a device that uses a cylinder containing compressed air as a source to supply breathable air and provide protection for the human body. It is mainly used in firefighting, chemical, petroleum, metallurgy, shipbuilding, mining, laboratories, oil depots, warehouses, and other departments for emergency rescue and disaster relief. It enables firefighters or emergency rescue personnel to safely and effectively perform firefighting, emergency rescue, disaster relief, and medical rescue operations in environments with smoke, toxic gases, dust, or oxygen deficiency.
