Type of foam used on standard wholetime appliances |
AFFF(Aqueous Film Forming Foam)
Specifically AFFF-AR (Alcohol Resistant AFFF)
|
|
How to get AFFF to work through hosereels from a standard wholetime appliance |
Get water to work - PTO, tank valve, high pressure, hose reel valve open, rev to operating pressure Turn silver ‘hose reel flow’ wheel to 125 lpm - 1 or 3 Turn small red hosereel foam lever to ‘FOAM’ This will give 1% or 3% foam solution - normally use 3% Branch operator should have the hosereel branch open with water flowing away from the fire until foam comes out - then point at fire |
|
How to knock off and flush AFFF from hosereels on a standard wholetime appliance |
Turn hosereel foam lever to ‘FLUSH’ Open ‘hosereel flow’ wheel to 125 lpm - 3 (this will flush the foam out as quickly as possible) Operate hosereels that have had foam through them until clear water is running through Turn ‘hosereel flow’ wheel and hosereel foam lever to OFF Knock-off pump |
|
How to get AFFF to work through main deliveries and hosereels |
Get water to work Move lever to tank to inductor Move RTP to desired setting (15 lpm per delivery in use for standard branches or 7.5 lpm for FB5X) Branches to be aimed away from fire and operated until foam solution comes out before using on fire |
|
How to knock off and flush after using AFFF through main deliveries and hosereel |
Turn foam lever back to horizontal ‘pick up to tank’ position Open RTP wheel all the way to flush foam out as quickly as possible Open branches on all deliveries/lines used until clear water running through then knock off Close RTP back to zero |
|
|
What does RTP stand for? |
Round the Pump Proportioner |
|
|
Difference between the High Pressure Foam System and the Round The Pump Proportioner Foam System on a standard wholetime appliance |
High Pressure foam system adds AFFF to the High Pressure system only, so foam only comes from the hosereels. The RTP adds AFFF to the whole pump, so foam comes from all deliveries and hosereels |
|
How much AFFF should be inducted for a 3% foam solution using standard branches? (Midmatic , ultimatic, smoothbore) |
15 lpm per delivery/branch in use Example: For 1 ultimatic and 1 midmatic branch in use simultaneously- turn the RTP to 30 lpm |

|
How much AFFF should be inducted for a 3% foam solution using the FB5X branch? |
7.5 lpm per FB5X branch in use |
|
|
What settings does the High Pressure Foam Hosereel Flow silver wheel/knob have? |
125 lpm - 1%, 3%, 6% 80 lpm - 1%, 3%, 6% |
|
|
What settings does the RTP foam flow regulator (silver knob/wheel) have? |
15 lpm increments from 0 lpm up to 120 lpm |
|
|
Capacity of the foam tank on a standard wholetime appliance |
70 litres |
|
|
What is the difference between ‘primary aspirated’ foam and ‘secondary aspirated foam’ ? |
Back (Definition) |
|
|
Recommended minimum application rate for finished foam AFFF on spills/bunds |
4 lpm per m2 for 15 minutes |
|
|
Product names of foam concentrate used on standard AFFF appliances and CAFS appliances |
Standard AFFF - Moussol CAFS - Sthamex |
|
