What are the different fire patterns?
Various types of fire patterns, such as; “V-shaped”, “hour-glass”, and “inverted cone”, have come from common observation at actual fire scenes.
What is the typical burn pattern for a fire?
The pour pattern by liquid accelerant is the typical burn pattern identified in the arson fire scene. During burn test paint thinners have been poured on the floor and wooden chairs in this compartment. Gasoline, kerosene, and paint thinner are the most common fuels as an accelerant.
What are V patterns found in fires?
When a fire burns against combustible wall, it creates an inverted “V” pattern. As the fire burns up and out it reaches the ceiling. Now the fire can no longer burn up, only out. This creates an hourglass pattern that consists of both a “V” pattern and an inverse “V” pattern.
What are three causes of fire patterns?
Fire patterns may be created by flame impingement, hot gases, smoke, and other products of combustion. The area of most damage may not indicate the point of origin.
What are the 4 elements of extinguishment?
All the four elements essentially must be present for the occurrence of fire i.e. oxygen, heat, fuel, and a chemical chain reaction. If you remove any of the essential elements, the fire will be extinguished.
What is the V pattern?
The V-Pattern is a powerful reversal pattern seen in all markets, all time-frames and in all instruments. The “V” patterns are formed when its trend is sharply switched from bearish to bullish (in case of V-Bottom) or bullish (or sideways) to bearish (in case of V-Top patterns).
What does a classic V burn pattern indicate?
Classic V. The burn pattern is narrower at the bottom, and spreads up and outward, forming a V. Usually indicated the that this was a accidental fire, and no accelerant was used. Inverted Cone/V.
What are fire indicators?
Smoke and Air Track: Smoke conditions and the pattern of smoke and air movement are two of the most important indicators of fire behavior. However, do not get so focused on visible flames that you miss more important, but subtle building, smoke, air track, and heat indicators.
What is the difference between A and V-pattern?
When the eyes diverge more than 10 prism diopters (PD) from upgaze to downgaze, an A-pattern is present; when the eyes converge more than 15 PD from upgaze to downgaze, a V-pattern is present. Other types of vertical incomitances, which are less common, include X, Y, and lambda patterns.
How do you trade the V-pattern?
A conservative way to trade the V-bottom would be to wait for a break and close above the neckline and to attempt a long position once price pulls back to the neckline and gets rejected.
