WEARING THE IFD
1. Open the waist belt buckle.
2. Loosen the waist belt on both left and right sides.
3. Wrap belt around waist and close quick release buckle to secure the IFD pouch waist belt.
4. Adjust waist belt on both the left and right sides to ensure a snug comfortable fit.
5. Slide the webbing keepers on the waist belt towards the loose ends to reduce the length of the
webbing’s free end.
6. The IFD can be worn in front or around the back.
7. In case of emergency, follow all safety instructions. DO NOT undo the IFD waist buckle.
8. Once outside of any enclosed cabin/space, the IFD can be inflated manually.
CAUTION - To avoid injury to the user or damage to the IFD, the IFD should never be worn under
clothing or anything else that might restrict inflation.
INFLATING THE IFD
Manual Inflation
To manually activate the inflator, jerk the red manual inflation handle upwards, ensuring the lanyard
extends fully. Note: If the IFD is worn on the back of the waist during normal procedures move it
around to the front of the waist for ease of inflation. Manually activating the inflator releases CO
2
gas
into the inflation cell, rapidly inflating the IFD. The IFD should inflate within five seconds.
If the IFD does not completely exit its innermost plastic pouch, this pouch can be torn by hand along the
edge of the pouch’s seal to aid removal of the IFD bladder.
>>WARNING<< Do NOT inflate the IFD while inside an enclosed cabin/space as that will prevent
or severely inhibit emergency egress.
CAUTION: If the MD3080 has already been orally inflated, subsequent CO
2
inflation could over-
pressurize and damage it.
Oral Inflation
Although a properly armed IFD will correctly inflate manually, the inflation CO
2
can diffuse slowly
through the bladder fabric and a slight reduction in pressure in the bladder is apparent several hours
after inflation. Therefore, oral top-up inflation may be required during prolonged immersion or in a non-
emergency or extreme cold situation.
To orally inflate the IFD:
1. If necessary, open the top flap on the IFD outer pouch and remove the inner sealed pouch
containing the IFD. Tear open the innermost pouch, unfold the bladder.
2. Locate the oral inflator tube.
3. Remove the cap on the oral inflator tube.
4. Using your mouth, blow into the tube until the IFD is fully inflated.
5. To deflate, reverse the cap on the oral tube and use it to depress the valve in the oral tube.
