Introduction
Gear: Fire Extinguishers
ABC Dry Chem
Monoammonium phosphate
AB and C
Blankets, melts then smothers burning fuels
Nonconductive
It works, but isn't great for basically anything. Super messy.
BC Dry Chem
Sodium Bicarb
BC only, but will sort of work on A
Same use as ABC
CO2
BC
Good for electrical and grease
Not terrible on A, but must protect from reiginition
Static risk!
Water Cans
Class A or sort of B
With or without foam
Fantastic- basically the best option for professionals with ordinary combustibles and normal fires
Airway Pharmaceuticals
NAVEL
Ipratropium anticholinergic
Albuterol ẞ-2 agonist, potassium
Oxygen
Booster Reel
What is it?
Semi-rigid hoseline on a reel
Introduced by Seagrave in 1910! Actually for chemical trucks (Bicarb reaction for pressure)
Initial hoses could be charged up to 800 psi!
Most commonly found on type 3 or smaller engines
Some type 1's though do have them
Can be mounted on the front, amidships, in a rear compartment or as part of a skid unit
Generally 150-200' length with semi-permanent nozzle attached
1-inch hose
Hydraulics
Can flow 10-60 GPM, general performance more like 30 GPM
Friction loss:
52 psi at 30 GPM
184 psi at 60 GPM
NP~= 100 psi
Required PDP= 52+100 = 152 minimum…
Can be more in the 200+ range if trying to get more GPM
Advantages
Easy to deploy and store
Can be charged on the reel (to a degree)
Disadvantages
Low flow rate
Limited length
Limited nozzle options
Appropriate uses:
Trash fires
Dumpster or small outside fires
Grass fires
Wildland initial attack
Transitional attack with an undercrewed engine
Cleaning trucks
Inappropriate uses:
Interior operations
Car fires
Defensive fires
Long hose lays
