Fire Flashcards
BA
Explain the starting procedure:
(6)
Apparatus leak test
• Switch off the demand valve.
• Open the cylinder valve slowly, close it and observe the gauge. It should not fall more than 10 bar per minute.
Don the apparatus
• Check all straps are in good condition, adjust the stars so the back plate fits snugly.
• With demand valve off, turn on the cylinder slowly.
Check for positive pressure
• Put the mask on.
• Spread head harness and place over head.
• Place chin in facemask chin cup, tighten lower straps first then upper straps (holding breath). Tighten centre strap if necessary.
• First breath will switch LDV to positive pressure mode, breathe normally.
• Lift mask seal off the face with 2 fingers, air pressure should flow out of the mask.
• Allow mask to re-seal. Hold breath and check there is no leakage from exhale valve.
Check face mask for leakage and test the whistle
• Close cylinder valve and breathe gently to exhaust air from system.
• Observe gauge, whistle will alarm at between 60 bar to 50 bar.
• Continue breathing down the system. Once empty, hold breath for approximately 3-5 seconds - the facemask should collapse and hold to face indicating a positive seal.
Check the actual pressure gauge
• Turn the cylinder on fully and the check the reading on the pressure gauge.
Proceed to fire location
• Adjust your flash hood over the edges of the mask so that there is no skin showing and all the straps are tucked into place.
• Fit your helmet and put on your gloves.
• Check in at entry control, confirm name and this together with your pressure and time of entry will be noted on your tally and left with E.C.O.
• Carryout the teams brief.

What is ISC & monthly maintenance:
Allows ships to receive add. water from shore to fight fires.
Monthly maintenance:
- In place, bolts present

The
Explain the pressure of a BA bottle and it’s required amount of air:
A BA bottle needs to hold atleast 1200l OR 30min of air.
6l bottle x 200bar = 1200l
4l bottle x 300bar = 1200l
1 bar is roughly the atmospheric pressure at sea level, therefore 200bar will be 200 times the volume a gas occupies at sea level (hence why 6 litres at 200 bar is the equivalent to 1200l)
What is meant by positive pressure BA and what is the positive?
Pressure inside mask is higher than outside: Expels toxic gas/smoke.
AFFF definition and operation:
Aqueous Film Forming Foam
