What is Propane? -ANSWER ✔✔ Propane is a colourless, easily liquefied
gaseous hydrocarbon. It's extremely flammable. The chemical formula is
C3H8. Manufactured by separating it from natural gas and light crude oil.
Propane is gaseous at normal atmospheric temperatures and pressures
What is "Boiling Point"? -ANSWER ✔✔ The temperature at which a liquid
boils and turns to vapour.
What is Propane's 'boiling point'? -ANSWER ✔✔ - 42.1
What are some common uses in construction? -ANSWER ✔✔ Heaters, Torches,
Forklifts, and Powered elevating work platforms
How much heavier is propane than air? -ANSWER ✔✔ 1.5 times as much
Why is it a potential for suffocation? -ANSWER ✔✔ It will settle into low lying
areas. It displaces oxygen in the environment (We need oxygen to breath)
What is "Range of Flammability" and why is it important?
Flammable gas which will mix with oxygen in the air to support combustion has a
range of flammability.
Too little flammable gas and ignition cannot take place. Too much flammable gas
and the gas displaces the oxygen necessary in the air to support combustion which
will also prevent ignition (don't worry about # in picture)
What is UEL/LEL? Where can this information be found for gases?
The amount of a specific gas necessary in the air to support combustion is called
the Upper and Lower Explosive Limits or UEL and LEL for short.
For gases, this information can be found in the Physical and Chemical Properties
section of the Safety Data Sheet (SDS)
