What is the significance of identifying the point of origin in fire investigation?
What is the significance of identifying the point of origin in fire investigation?
- It indicates where the fire was intentionally set, ruling out accidental causes.
- It allows investigators to understand the fire's spread and potential causes. (correct)
- It immediately identifies the materials that fueled the fire.
- It helps determine the exact temperature at which the fire started.
A fire investigator notes that a fire spread rapidly upwards along a wall. What principle of fire behavior does this observation primarily demonstrate?
A fire investigator notes that a fire spread rapidly upwards along a wall. What principle of fire behavior does this observation primarily demonstrate?
- Fires follow the path of least resistance, often moving upwards due to heat rising. (correct)
- Fires extend horizontally before extending vertically.
- Fires always spread in a circular pattern from the origin.
- Fires are not influenced by the materials they encounter.
In what way might wind MOST significantly influence the behavior of a fire?
In what way might wind MOST significantly influence the behavior of a fire?
- Wind always slows down the rate at which a fire consumes fuel.
- Wind only affects the color of the smoke produced by the fire.
- Wind has no impact on indoor fires.
- Wind can change the direction and speed of the fire's spread. (correct)
A fire spreads through a building, moving from a room with highly flammable liquids to a room filled with dense, non-flammable materials. How does the 'path of least resistance' principle apply in this scenario?

During a fire investigation, an investigator observes that the fire spread upwards and outwards from a specific location, leaving a V-shaped burn pattern on the wall. How might the investigator interpret this pattern in relation to the point of origin?

Flashcards
Point of Origin
Point of Origin
The specific location where a fire begins, from which it spreads outwards and upwards.
Fire spread direction
Fire spread direction
Fires spread in all directions, both horizontally and vertically, from the point of origin.
Path of Least Resistance
Path of Least Resistance
Fires tend to follow the easiest path available, influenced by factors such as available fuel and ventilation.
