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 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 - (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.
Electric Match - (ANSWER)a device that uses an externally applied electric current to ignite a
combustible compound.
Flame Paste - (ANSWER)Flammable paste that burns with an orange flame
Flammable - (ANSWER)easily ignited and quick burning. It can be in liquid or solid form.
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 - (ANSWER)Creates an instantaneous flash and burns very quickly
Flash Paper - (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 - (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 - (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 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 - (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 - (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 - (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 - (ANSWER)A thick fog that stays close to the ground. As it is warmed or agitated, rises and
gradually disappears.
Lycopodium Powder - (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) - (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 - (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, heat, chemicals, biohazards, and airborne
matter.
Proximate Audience - (ANSWER)An audience closer to pyrotechnic devises than allowed by NFPA 1123.
