The Role of THDF Series Escape Respirator
The THDF series escape breathing apparatus was approved by the IMO.98(73) resolution of the International Maritime Organization. On July 1, 2002, it became a mandatory marine product designed and manufactured under the “International Fire Safety System Ruleâ€. This product has passed CCS certification and has a ship inspection certificate. It consists of a compressed air bottle, a pressure reducer, a pressure gauge, a gas pipeline, a hood, and a backpack. It can provide individuals with constant-current gases for 10 or more minutes, and is available in toxic, harmful, smoke, and oxygen-deficient environments. The personnel escaped use. The pressure gauge on the cylinder always shows the pressure in the cylinder. An exhalation valve is installed on the head cover or the full face cover, and the gas exhaled by the user is discharged out of the protective cover. Since the gas pressure in the protective cover is greater than the atmospheric pressure of the external environment, the ambient air cannot enter the protective cover, thereby achieving the purpose of respiratory protection. The device is small in size and can be carried by people without affecting the normal activities of the personnel. Its structure is simple, easy to operate, and the user can operate correctly after reading the instructions for use without training.
