Firing Ops (WEEK 6) Flashcards
What two Codes allowing firing operations?
Public Resources Code (4426), Health and Safety Code (41801)
Who do you notify prior to firing on Initial Attack?
IC, Ops, or immediate Supervisor
What is Backfiring?
Set ahead of the main fire influencing the main fire with intent to slow, stop, or redirect spread
What is burning out?
Fire set w/ in the control line to consume fuel between the fires edge and control line
Five parts to firing group organization?
Firing observer, Ignition team, holding team, Mop- up team, Reserves
Five firing techniques?
Strip- parallel to control line (Flanking), edge- along edge of line (backing), spike- perpendicular to line (flanking), dot (backing, flanking, head), ring-firing outer perimeter (backing, flanking and head)
Miles of fire laid down by one single torch?
½ to 1 miles
Reflex time for 1 engine and 1 strike team of engines from order to lighting?
5 min for an engine and 10-15 min for a strike team
Spot fire RISK ASSESMENT?
Holding vs. Terminating
Personnel briefing include what when firing out?
Objectives, Chain of Command, Fire Situation, Predicted fire weather, Safety, Communication, Problem areas, Fire Behavior Predictions.
What 9 objectives do you have to have when developing a burn plan?
Objectives, risk vs. gain, time frame, type of fire behavior, burn zone, safety, access/ egress, hazards, controls.
What is the reflex time to fire (engine)(task Force/ST)?
5 min for single from order to fire, And 10-15 min for a task force or strike team from the order to the fire.
Quick fire flare launchers fire at what range?
Up to 300ft. and burns @ 4000* F and the spread coverage of 10ft-20 ft
Plan need define:
An anticipated operational event where time exists for detailed planning and logistical preparation. (For next op period for next couple of needs)
Immediate need Defined:
Is a tactical operation that must be immediately implemented for the protection of life and property.
What’s the rule of thumb for a burn zone?
2x max flame length, 4x average flame length.
What are 3 types of firing behavior?
- Head fire = High ROS, FL, & BTUs
- Flanking = Med ROS, FL, BTUs
- Backing = Low ROS, FL, BTUs
In drafts are what?
Air movement towards a convection column.
Radiant ignition usually occurs within what?
1X the flame length.
Check lines are used as what?
Temporary opened ended lines, short hose lays, scraped lines, and natural break in fuel, back to back with another team.
What is the rule of thumb for predicting spot fires in regards to rh?
20-30%
Firing plans must be?
Well designed, monitored, and controlled
Backfire conditions of use are?
Rapid rate of spread, fire intensity to secure for direct. Immediate threat to hazard, life and property, and resistance to direct attack due to terrain
A burned zone =
4x the average flame length
