Air respirator check before use 1. Check that the lens, strap, ring seal, exhalation valve, suction valve of the full face cover are intact, and the supply valve is securely connected. The area of ​​the full cover must be clean, free of dust or contaminated with acids, alkalis, oils and harmful substances. The lens should be wiped clean.
2. Is the supply valve action flexible and the connection to the medium pressure conduit is secure?
3. The air source pressure gauge can indicate pressure normally.
4. Check if the backing is intact and the left and right shoulder straps and the left and right waistband sutures are broken.
5. Is the fixation of the gas cylinder assembly firm and the connection between the gas cylinder and the pressure reducer firm and airtight?
6. Open the bottle head valve. As the pressure in the pipeline and decompression system rises, the short sound of the gas source residual pressure alarm will be heard. After the bottle head valve is fully opened, the pressure in the cylinder shall be checked at 28 MPa. Within the range of ~30Mpa.
7. Check the airtightness of the machine. Close the bottle valve after opening the bottle valve for 2 minutes. Observe that the pressure drop within 1 min of the pressure gauge does not exceed 2 Mpa.
8. Check the matching of the full-face mask and the supply valve, close the intake valve of the supply valve, wear a full-face mask to inhale, and the intake valve of the supply valve should be automatically opened.
9. According to the use of regular inspection of the above items. When the air respirators are not in use, check the above items once a month.
Air breathing apparatus wearing method
1. When wearing an air-ventilator, first unplug the quick connector (to prevent damage to the full face mask when wearing an air-ventilator), and then put the air respirator behind the person's body (bottom of the bottle head valve), according to body size adjustment Shoulder straps and belts are appropriate for comfort and comfort.
2. Connect the quick connector and lock it. Place the full face mask on your chest so that you can wear it at all times.
3. Place the inlet valve of the supply valve in the closed state, open the bottle valve, and observe the pressure indication to estimate the time of use.
4. Wear a full face mask (without tying) for 2 to 3 deep breaths. Feel comfortable. When the breath or breath is exhaled, the supply valve should stop supplying air. There is no “click†noise. After everything is normal, tighten the full face strap so that the full face mask fits the person's forehead and face.
When wearing a full face mask, do not overtighten the laces and feel comfortable on the face. There is no obvious tenderness. After the full face mask and the person's forehead and face are well-fitted and airtight, take a deep breath and the intake valve of the supply valve should be automatically opened.
5. After the air respirator is used, unfasten the strap of the full-face mask, separate the fire helmet and the full-face mask, remove the full-face mask from the head, and close the intake valve of the supply valve. Remove the air respirator from the body and close the bottle head valve.
note:
a. Once you hear the alarm, you should prepare to end work in the danger zone and leave the danger zone as soon as possible.
b. The pressure gauge is fixed on the shoulder strap of the air breathing apparatus. The pressure indication value can be observed at any time to judge the remaining air in the cylinder.
c. Unplug the quick connector. After the bottle valve is closed, the remaining air in the pipe is released and the quick connector is removed.
