FDNY E-27 COF EXAM WITH COMPLETE SOLUTIONS
100% VERIFIED!!
Blank Ammunition - ANSWER (Theatrical Ammunition) a type of ammunition for a
firearm that contains gunpowder but no bullet or shot
Combustible - ANSWER capable of catching fire or burning; can be a fiber or liquid
Cryogenic - 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 ANSWER A pressure container, low-pressure container or
atmospheric container of any size designed or employed for transportation, handling, or
storing of cryogenic fluid, and which utilized venting, insulation, refrigeration or a
combination thereof to keep the pressure with design limits for such containers and
maintain the contents in a liquid state.
Danger Area - 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 - ANSWER The solid form of carbon dioxide. It is primarily used as a cooling
agent but often used to create theatrical/performance fog.
Electrical Ignition or Electric Match - ANSWER a device that employs an externally
applied electric current to initiate combustion in a combustible compound.
Flame Paste - ANSWER Flammable paste that burns with an orange flame
,Flammable - ANSWER easily ignited and rapid burning. Can be liquid or solid.
Flammable Cryogenic Fluid - ANSWER A cryogenic fluid that is flammable in its vapor
state
Flash Cloth - 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 - ANSWER Popular for magician's tricks. It burns quick with a bright orange
flame and vanishes without residue.
Flash Cotton - ANS Affords instantaneous flash and burns in jiffy
Flash Paper - ANS Paper made from nitrocellulose, which burns quick and complete
with bright orange flame without leaving any ash. It is used mainly for coin and close up
magic effects.
Fog ANSWER Produced by glycol or glycol/water mixtures heated until the fluid
vaporizes producing a thick translucent or opaque cloud of liquid droplets.
General Supervision - 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 - ANSWER The transportation of a material in its container, the removal of the
material from its container, or any other activity or process involving the material,
except its storage or use.
Haze - ANSWER A subtle fog formed from liquid droplets that is designed to be mainly
transparent and only to reveal lighting beams. Like fog, it can be generated with a glycol
/ water solution.
, Health Hazard - 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 which are toxic, highly
toxic and corrosive.
Liquid - ANSWER A material having a melting point equal to or less than 68 degrees F
and a boiling point 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 - ANSWER A dense fog that hugs the ground. As it is heated or
disturbed, rises and gradually lifts.
Lycopodium Powder - ANSWER Is a very fine, yellow powder obtained from the spores
of a plant which may be used to produce fire effects.
Material Safety Data Sheet / Safety Data Sheet (MSDS / SDS) - 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 the health and physical
hazards of the material used, procedures that should be followed in case of an
emergency and safety work practices. MSDS does not show the cost of the hazard.
Permit - ANSWER A written statement issued by the commissioner authorizing the
manufacture, storage, handling and use of transportation of hazardous materials or
other material, or to conduct an operation or to maintain a facility, for which a permit is
required by the NYC Fire Code.
Personal Supervision - ANSWER Supervision by a COF holder who is required to be
personally present on the premises, or other proximate location acceptable to the
FDNY, while performing the duties for which the certificate is required.
Personal Protective Equipment (PPE) - ANSWER Protective clothing, helmets, goggles,
or other garments or equipment designed to protect the user from bodily injury or
infection. The hazards addressed by protective equipment include physical, electrical,
