PROPANE EXAM WITH COMPLETE
SOLUTIONS
Propane - ANSFossil fuel that is found mixed with natural gas and petroleum deposits in
rocks deep underground.
Expansion Ratio of Propane - ANS270:1
Vapor density of Propane - ANS1.56, making it heavier than air.
Propane disbursement - ANSseeks low area and accumulate until it dissipates or finds
and ignition source.
Propane - ANSLEL 2.3 UEL 9.5
1 gallon of propane weighs - ANS4.23 lbs
Propane ignition temperature - ANS920 degrees Fahrenheit and 1120 degrees
Fahrenheit
Natural form propane - ANSis colorless and odorless
Mercaptan is added to propane for smell - ANS20% below lower explosive limit. 1
pound per 10,000 gallons, equates to 1 part per billion.
Propane is in a liquid state when contained and stored - ANSSpecific gravity of propane
.504 versus water 1.0 which makes it lighter than water.
Propane when released into the atmosphere - ANSwill change from liquid to vapor,
during a release cloud that is visible is not product but condensed moisture in air that is
cooled by leaking product.
Apparatus placement propane emergency - ANSPosition prior to and upwind of the
hazard area if at all possible & determine most efficient water supply.
Other units shall stage upwind and prior to the affected area and await an assignment
from the engine company or Incident Commander.
Outside Propane Leaks - ANS1- Safe perimeter shall be established using
detection/monitoring equipment- these must be intrinsically safe and bump tested prior
to entering hot zone.
