Fuel, Weather and Topography
What are the features of a SFD type3 engine?
Hose bed/Pump Booster tank(500 Gallons) Equipment compartments 1000 GPM pump Aux pump rated at 150 GPM(Pump and Roll) Can be a stand alone unit
What is a patrol unit?
1 Ton pick up
130 GPM “Skid Mount” pump
300 Gallon Tank
Must be accompanied by their Type1 Engine
What are the 2 different types of thread in wildland couplings?
National Standard Thread
National Pipe Straight Hose
How much does 1” wildland hose weigh dry?
8 pounds per 100’
How much does 1.5” wildland hose weigh?
14 Pounds per 100’
What is the flow for 1” wildland nozzles?
10 or 25 GPM @100 PSI
What is the flow for 1.5” wildland nozzles?
20 or 60 GPM @100 PSI
What size hose are forestry clamps to be used on?
1” and 1.5” single jacket only
How many gallons is carried in a back pack pump?
5 Gallons
What is carried in the wildland hose pack?
2 - 100’ single jacket 100’ length of 1.5”
In the wildland pack, what color pull cord represents what?
Orange/Red closest to the body
Blue is the outside pack
What size hose can fit in the cascade hose roller?
1”-3”
What are the specs of the SFD Wildland Nomex?
7.5 ounce, allows to wear in single layer configuration
What is the difference between wildland and station boots?
Wildland boots do not have a steel shank or toe
What is a safety zone?
Usually a recently burned area used for safety if the line gets burned over or spot fires make the line unusable.
What is a deployment zone?
Similar to the Safety Zone, but area for shelter deployment, not big enough area to protect firefighters from radiant heat
What is a temporary refuge area?
An area that is available for immediate refuge for temporary shelter if the routes to the safety zones are comprimised
What are the strategic considerations for wildland suppression?
- Direction and speed of travel
2. Structures threatened
What is the difference between; Initial attack, Extended attack, Major fire?
Initial Attack - can be handled by first alarm companies, without need of reinforcements with in 2 hours
Extended Attack - Multiple alarm, 1st alarm companies need augmenting
Major Fire - Days to weeks to extinguish
Describe Direct attack.
Directly applying water to the fires edge
Describe Indirect attack.
Control line is a considerable distance away, involves placing a containment line in and burning area from fires edge to the control line
Describe Parallel Attack.
Laying down an indirect wet line down and burn out from fires edge to the wet line
What are some mobile attack safety considerations?
- Maintain visual contact, spray windshield or mirror to get drivers attention
- Hoseline must be charged prior to advancing to area
- Running will cause you to miss/pass fire
- Extinguish all fire
- Work on or near the fire line
- Watch for obstacles
What are the mobile attack methods?
Flanking - Directly on the fire edge from an anchor point
Pincer - Using 2 or more engines flanking to meet at the head of the fire.
Tandem - Flanking operation in which 2 engines follow each other
Envelopment - Simultaneously attacking key points of the fire to develop multiple anchor points
Splitting the head - Very dangerous, using 2 or more engines, drive into the black from and anchor point and go for the head without regard for the flanks
What is the max amount of hose on the ground for structure protection?
200’ Max
