Q: What happens if a vapor has a density value LESS than 1?
Answer:
The vapor is lighter than air and will rise.
(Ex. Hydrogen Gas)
Q: What happens if the vapor has a density value EQUAL to 1?
Answer:
The vapor is the same weight as air and would mix with the air easily.
(Ex. Carbon Monoxide)
Q: Why is in helpful for firefighters to have a good understanding of a substance’s vapor
density?
Answer:
They may be able to predict the spread or migration of the vapors and possibly remove any
ignition sources that may be in the vapor’s path.
Q: The ratio of the density of a liquid or solid, as compared to the density of an equal volume of
water, with water having an assigned value of 1 is called?
Answer:
Specific Gravity
Q: What happens when a liquid or solid has a Specific Gravity higher than 1?
Answer:
The liquid or solid is heavier than the water and will sink.
(Ex. Carbon Disulfide)
Q: What happens when a liquid or solid has a Specific Gravity lower than 1?
Answer:
The liquid or solid is lighter than the water and will float.
(Ex. Gasoline, Kerosene, and Wood)
Q: What is the danger of using water on a flammable liquid with a low specific gravity?
Answer:
The water may actually spread the liquid and the fire rather than putting the fire out.
Q: The degree of rapidity with which a substance evaporates to a gaseous state is called?
Answer:
Volatility
Q: The lowest temperature at which a substance begins to release ignitable vapors sufficiently
fast enough to “flash” when exposed to an outside ignition source but DOES NOT CONTINUE
TO BURN is called?
Answer:
The Flash Point
Q: True or False: Anything that can burn has a flash point.
Answer:
True
Q: The flash point of a substance we usually call “flammable,” such as gasoline, is much
than the flash point of a substance we wouldn’t call flammable, such as steel.
Answer:
Lower
Q: What are the 3 steps taken to determine the flash point of a substance?
Answer:
Step 1: Ensure that the pressure and oxygen content of the atmosphere are constant and that the
substance being tested is pure.
Step 2: Beginning at a very cold temperature, the substance is heated very slowly and begins to
produce vapors.
Step 3: The Vapors are given an external ignition source (a test flame, for example) and the
temperature at which these vapors flash or burn is considered the flash point.
Q: Flash Point determines the __ of all liquids and solids.
Answer:
Flammability
Q: The LOWEST temperature at which a substance produces ignitable vapors sufficiently fast
enough to “flash” when exposed to an outside ignition source and then CONTINUES TO BURN
is called ______.
Answer:
The Fire Point
Q: The process of initiating self-sustained combustion
Answer:
Ignition
Q: Combustion is a _ reaction.
Answer:
Chemical
Q: What are the two ways a substance can reach its ignition temperature?
Answer:
(1) Piloted Ignition
(2) Auto-Ignition
Q: The introduction of an EXTERNAL ignition source like a spark, match or open flame is
called?
Answer:
Piloted Ignition
