FDNY E-27 COF Exam with all Correct & 100% Verified
Answers |Latest Version |Already Graded A+
Blank Ammunition ✔Correct Answer-(Theatrical Ammunition) a type of ammunition for a
firearm that contains gunpowder but no bullet or shot
Combustible ✔Correct Answer-capable of catching fire or burning; can be a fiber or liquid
Cryogenic ✔Correct Answer-A fluid having a boiling point lower than -130 degrees F at 14.7
pounds per square inch absolute (psia) (an absolute pressure of 101.3kPa)
Cryogenic Container ✔Correct Answer-A pressure container, low-pressure container, or
atmospheric container of any size designed or used for the transportation, handling, or storage
of cryogenic fluid, and which utilized venting, insulation, refrigeration of a combination thereof
to maintain the pressure within design parameters for such containers and to keep the contents
in a liquid state.
Danger Area ✔Correct Answer-The immediate area surrounding the special effect or
pyrotechnic performance. The distance of the danger area depends on the actual effect that is
taking place.
Dry Ice ✔Correct Answer-The solid form of carbon dioxide. It is primarily used as a cooling
agent but often used to create theatrical/performance fog.
Electric Match ✔Correct Answer-a device that uses an externally applied electric current to
ignite a combustible compound.
Flame Paste ✔Correct Answer-Flammable paste that burns with an orange flame
Flammable ✔Correct Answer-easily ignited and quick burning. It can be in liquid or solid form.
Flammable Cryogenic Fluid ✔Correct Answer-A cryogenic fluid that is flammable in its vapor
state
Flash Cloth ✔Correct Answer-A cotton based material which is stronger than the traditional
flash paper but produces the same orange flame effect with no residue. It can be sewn into
objects allowing the designer to create different effects.
Flash Cord ✔Correct Answer-Popular for magician's tricks. It burns quick with a bright orange
flame and vanishes without residue.
Flash Cotton ✔Correct Answer-Creates an instantaneous flash and burns very quickly
, Flash Paper ✔Correct Answer-Paper made from nitrocellulose and burns very quickly and
completely with a bright orange flame that leaves no ash. It is commonly used for coin and close
up magic effects
Fog ✔Correct Answer-Created by glycol or glycol /water mixtures heated until the fluid
vaporizes creating a thick translucent or opaque cloud of liquid droplets.
General Supervision ✔Correct Answer-Supervision by the Certificate of Fitness holder who is
responsible for performing the duties of the certificate holder but need not be personally
present on the premises at all times. When using hazardous special effect materials, when COF
is not present, material must be locked and secured.
Handling ✔Correct Answer-The movement of a material in its container, the removal of the
material from its container, or any other action or process that may affect the material, other
than its storage or use.
Haze ✔Correct Answer-An unobtrusive cloud made of liquid droplets that are intended to
primarily reveal lighting beams. Similar to fog, it can be created with a glycol / water mixture.
Health Hazard ✔Correct Answer-A classification of a chemical for which there is a statistically
significant evidence that acute or chronic health effects are capable of occurring in exposed
persons. The term "health hazard" includes chemicals that are toxic, highly toxic and corrosive.
Liquid ✔Correct Answer-A material heaving a melting point that is equal to or less than 68
degrees F and a boiling point that is greater than 68 degrees F at 14.7 psia. When not otherwise
identified the term "liquid" includes both flammable and combustible liquids.
Low Lying Fog ✔Correct Answer-A thick fog that stays close to the ground. As it is warmed or
agitated, rises and gradually disappears.
Lycopodium Powder ✔Correct Answer-Is a fine, yellow powder derived from the spores of a
plant that can be used for fire effects.
Material Safety Data Sheet / Safety Data Sheet (MSDS / SDS) ✔Correct Answer-A document
prepared in accordance with the regulations of the United States Department of Labor, as set
forth in 29CFR Part 1910.1200 or federally approved state OSHA plan which sets forth
information concerning a hazardous material. It contains health and physical hazards of the
material used, procedures that should be followed in case of an an emergency and safety work
practices. MSDS does not show the cost of the hazard.
Permit ✔Correct Answer-A written statement issued by the commissioner authorizing the
manufacture, storage, handling and use of transportation of hazardous materials or other
