What is a pincer fire attack?
Direct attack around a fire in opposite directions by two or more attack units. Usually conducted from the fire’s tail to head.
What are the three tactics for wildland fire suppression?
The methods of attack are direct, parallel, and indirect. Direct attack is made directly on the fire’s edge or perimeter (see Figure 3). The flames may be knocked down by dirt or water and the fire edge is generally treated by a follow-up fireline.
What is a parallel attack?
A parallel attack involves building fireline at a fixed distance from an active fire front and in a direction parallel to it (i.e. tangential). Parallel attack is implemented to minimize the horizontal length of fireline produced.
What is the purpose of an anchor point wildland firefighting?
An advantageous location, usually a barrier to fire spread, from which to start constructing a fireline. The anchor point is used to minimize the chance of being flanked by the fire while the line is being constructed.
What part of a ground cover fire spreads the most rapidly and usually does the most damage?
e head
e head is the part of a ground cover fire that spreads most rapidly. e head is usually found on the opposite side of the fire from the area of origin and in the direction toward which the wind is blowing. e head burns intensely and usually does the most damage.
What is flank attack in fire?
Flank attack – Attacking the fire along the flank or both flanks simultaneously, usually moving from the tail towards the head. Head attack – Attacking the head of the fire. This attack method is usually only successful on lower intensity fires and when the flanks of the fire have already been extinguished.
What do wildland firefighters do to try to reduce the spread of a fire?
Firefighters control a fire’s spread (or put it out) by removing one of the three ingredients fire needs to burn: heat, oxygen, or fuel. They remove heat by applying water or fire retardant on the ground (using pumps or special wildland fire engines) or by air (using helicopters/airplanes).
How do you fight a wildland fire?
To put out a fire, heat, fuel or oxygen must be removed. Putting dirt and water or retardant on fire removes the oxygen from the fuel. This allows a firefighter using a hand tool such as shovel, axe, rake or Pulaski to extinguish small fires.
What is a direct attack in fire?
Any treatment applied directly to burning fuel such as wetting, smothering, or chemically quenching the fire or by physically separating the burning from unburned fuel.
What is a parallel fire attack?
Method of fire suppression in which fireline is constructed approximately parallel to, and just far enough from the fire edge to enable workers and equipment to work effectively, though the fireline may be shortened by cutting across unburned fingers.
What does laces mean in firefighting?
Abstract. As an acronym, LACES stands for Lookout(s) – Anchor point(s) – Communication(s) – Escape routes – Safety zone(s) and has gradually become a guideline for wildland firefighter safety in various regions of Canada over the past 15 years or so.
Where does the flanking action start in a fire?
Flanking Action: The engine moves along the line as fast as the fire is put out. Sources: NWCG Glossary, Pyne et al (1996), TEIE (2005), http://www.chabotfire.comhttp://www.coloradofirecamp.com The action starts at a anchor point and creates a fireline along one flank of the fire.

What does parallel attack mean in fire management?
Parallel Attack is defined as a “method of fire suppression in which fireline is constructed approximately parallel to, and just far enough from the fire edge to enable workers and equipment to work effectively, though the fireline may be shortened by cutting across unburned fingers.” (NWCG)
