FUELS, WEATHER, AND TERMS
24
Fuels Fuel Fuel Any flammable or combustible substance available for fire consumption Any flammable or combustible substance available for fire consumption The most common fuels consumed during a natural cover fire: The most common fuels consumed during a natural cover fire: Grass, brush, trees, and crops Grass, brush, trees, and crops Other fuels encountered: Other fuels encountered: Structures, vehicles, farm equipment, Hazmat, etc. Structures, vehicles, farm equipment, Hazmat, etc.
25
Fuels Surface Fuels Surface Fuels Fuels found on the ground Fuels found on the ground Aerial Fuels Aerial Fuels Fuels on tops of trees and brush Fuels on tops of trees and brush Ladder Fuels Ladder Fuels Fuels connecting surface fuels to aerial fuels Fuels connecting surface fuels to aerial fuels
26
Fuels Light Fuels Light Fuels Short grass or light brush Short grass or light brush Medium Fuels Medium Fuels Brush up to 6 feet high Brush up to 6 feet high Heavy Fuels Heavy Fuels Thick/dense fuels over 6 feet high Thick/dense fuels over 6 feet high
27
Weather - Wind direction and velocity - Low humidity - High temperatures - Lots of sunshine - Low moisture - Time of day - Day of week
28
Terms Origin – Area where the fire started Origin – Area where the fire started Head – Part of the fire with the greatest rate of speed Head – Part of the fire with the greatest rate of speed Heel – Opposite end of the head. Also referred to as the “rear” Heel – Opposite end of the head. Also referred to as the “rear” Unburned – Area of Unburned fuel outside or adjacent to the involved area Unburned – Area of Unburned fuel outside or adjacent to the involved area
29
Black – area that the fire has consumed Black – area that the fire has consumed Flanks – The sides of the fire, roughly parallel to the main direction of the fire spread. Flanks – The sides of the fire, roughly parallel to the main direction of the fire spread.
30
Scene Size-Up
31
Windshield Size-Up Establish Command Establish Command Ask yourself these questions: Ask yourself these questions: What is burning? Fuel type/load What is burning? Fuel type/load How much area is currently involved? How much has burned already? How much area is currently involved? How much has burned already?
32
Windshield Size-Up (continued) How fast is the fire moving? How fast is the fire moving? Are there any exposure concerns? Are there any exposure concerns? Do I need additional resources? Do I need additional resources? Am I staged in a safe area? Am I staged in a safe area?
33
Fire Attack
34
Direct Attack Hierarchy of tool selection of a crew for “typical” light to medium fuel natural cover fires: Hierarchy of tool selection of a crew for “typical” light to medium fuel natural cover fires: Blower Blower Rake Rake Water/Foam Water/Foam
35
Direct Attack Establish a safe anchor point prior to starting fire attack Establish a safe anchor point prior to starting fire attack Start attack by the heel or a natural barrier Start attack by the heel or a natural barrier
36
Direct Attack Work in tandem to prevent fire from reigniting Work in tandem to prevent fire from reigniting Give ongoing reports to command Give ongoing reports to command
37
Direct Attack - Crew Crew Leader - Obtains portable radio, rake, and two flares - Obtains portable radio, rake, and two flares Crew Member - Obtains the blower and its extension tube Additional Crew Member - Obtains an Indian pack/pump pack - Obtains an Indian pack/pump pack
38
Brush Truck Operations Crew Leader - Walks ahead of truck as a spotter, obtains portable Crew Member #1 - Starts pump, drives truck watching other crew members - Starts pump, drives truck watching other crew members Crew member #2 - Deploys crosslay, walks along truck extinguishing flames - Deploys crosslay, walks along truck extinguishing flames
39
Indirect Attack Controlling the fire by constructing a control line along natural barriers or by removing/burning unburned fuel in the fire’s path Controlling the fire by constructing a control line along natural barriers or by removing/burning unburned fuel in the fire’s path
40
Natural Barriers Creeks Creeks Rivers Rivers Streams Streams Dirt Dirt Rock areas Rock areas
41
Manmade Barriers Roadways Roadways Parking lots Parking lots Ditches Ditches
42
Back Burning Method involves burning a fire line ahead of the fire to eliminate fuels for the fire to consume
43
Indirect Attack - Crew Crew Leader - Obtains portable, drip torch, and two flares - Obtains portable, drip torch, and two flares Crew Member - Obtains blower and extension tube or a water pack - Obtains blower and extension tube or a water pack Additional Crew Member - obtains a rake - obtains a rake
44
After the Fire Double check for hot spots Double check for hot spots Check back in with the IC – entire crew Check back in with the IC – entire crew Rehab tools Rehab tools Refill apparatus Refill apparatus Terminate command Terminate command

Safety
46
Safety Solid Incident Command Accountability Communications Escape Routes Safety Zones
47
Safety In the majority of NCF incidents, there are no lives at risk until the first firefighter arrives In the majority of NCF incidents, there are no lives at risk until the first firefighter arrives Prepare for the worst case scenario Prepare for the worst case scenario Place experienced personnel in crew leader and incident commander roles Place experienced personnel in crew leader and incident commander roles
