• Respect the whip
• Keep area clean

29
SCBA Connection

• Rated at 4500 psi

30
SCUBA Yoke

• Most rated at 3000 psi

31
Low Pressure SCBA Adapter

• Pop off regulator is set for 2216 psi.

32
Low Pressure SCBA Adapter

• The adapter has the same 4500 psi rated
  connection as the high pressure whips.

33
Station 14 SCBA Fill Station

• Open donor cylinder bank first.
• Crack fill gauge to proper rate.

34
Oxygen Fill Station

• Regulated fill rate of 300-600 psi/min.
• Will have vacuum system installed.

35
300 to 600 psi Per Min

• One unit on this gauge is 100 psi
• It should take 10 to 20 seconds for each 100 psi
  unit
• To fill a high pressure SCBA cylinder from 0 psi
  it will take _at_ 10 min.

36
Filling a Cylinder

1. Cylinder inspection
2. Cylinder connection
3. Open cylinder valve
4. Open lowest donor cylinder bank first
5. Open the fill valve at 300 600 psi/min

37
Handle With Care.

• Would you use an artillery shell as a wheel
  chock.
• Kinetic energy stored in a full 80 cubic foot
  cylinder exceeds one million foot pounds.

38
Transportation of Cylinders

• Regulations for commercial transporters
• Practical application in the fire department
  would be
• Vertical
• Protected contact with other cylinders
