What Federal Act requires anyone who releases a reportable quantity of a hazardous
substance, to include slow releases over a 24-hour period, to immediately notify the National
Response Center? - The Comprehensive Environmental Response, Compensation, and
Liability Act (CERCLA)
What Federal Act requires the development of emergency response plans that address fuel
spills and exposures to hazardous waste? - The Superfund Amendments and
Reauthorization Act (SARA)
What is a Material Safety Data Sheet (MSDS)? - A technical bulletin that describes how
to use, handle, and dispose of specific chemical hazards
What Federal Act(s) require MSDS be available and posted in all workplaces where hazardous
materials exist? - The Emergency Planning Community Right-to-Know Act (EPCRA) and
the Occupational Safety and Health Act (OSHA)
USDOT identifies hazardous materials using a 4-digit number denoting what information
about the hazard? - the first digit identifies one of nine hazmat classes; the last three
digits indicate the exact material
What type of fuel is in a fuel line colored black? - jet fuel
What do the four colors (blue, red, yellow, white) of the OSHA hazmat labeling system
represent? - blue - health hazard; red - fire hazard; yellow - reactive material; white -
PPE required
What do the numbers 0 through 4 represent in the OSHA hazmat labeling system? - the
degree of hazard; 0 - minimum; 1 - slight; 2 - moderate; 3 - serious; 4 - severe
What does a letter (A to Z) represent in the OSHA hazmat labeling system? - The type of
PPE required
Who is responsible for hazardous waste that exists on the airport? - The airport
operator
What Federal Act covers the treatment, storage and disposition of used oil and other hazmat
substances? - The Resource Conservation and Recovery Act
, How long may hazmat be stored on site before treating or taking off site? - 180 days
(270 days if disposal plant is 200 miles away or farther)
What is the fine if the emergency coordinator at an airport does not notify the NRC in the
case of an emergency? - $10,000, a year in jail or both
How often must certificated airports inspect and ensure immediate corrective action
concerning each tenant's fueling facilities? - once every three months
What is the fire triangle? - combustible material; oxygen; ignition source
Which has more explosive potential, Avgas or Jet-A? - Avgas
At what temperatures is Avgas most susceptible to ignition? - -50 to 30F
At what temperatures is Jet-A most susceptible to ignition? - 100 to 165F
What is a larger ignition risk, a partially full fuel truck or a mostly full fuel truck? -
Partially full, due to the greater mixture of fuel fumes and oxygen
At what point do vapors given off from a material form an ignitable mixture? - the flash
point
If a material has a flash point at or above 100F what is it considered? - combustible (ex.
Jet-A)
If a material has a flash point below 100F or a vapor pressure not exceeding 40psi, what is it
considered? - flammable (ex. Avgas)
At what temperature will a fuel ignite if compressed? - the auto ignition temperature
At what rate will flames spread once fuel is ignited? - the flame spread rate
How often must fuel tanks be checked for water (sumping)? - daily
Water is heavier than avgas and jet fuel; how long does it take for water to settle per foot of
fuel tank depth? - avgas - 15min ; JetA - 60min
Since fuel must be filtered for microorganism growth, what pressure difference between the
inner and outer portion of the filter indicates that the filter must be changed? - 15psi
What material is not recommended for above-ground fuel storage tanks? - fiberglass
What is one method to reduce underground fuel storage tank corrosion activity related to soil
resistivity? - cathodic protection
