NAFI CFEI OFFICIAL Exam Graded A+
CODE
A standard that is an extensive compilation of provisions covering broad subject
matter or that is suitable for adoption into law independently of other codes and
standards.
GUIDE
A document that is advisory or informative in nature and that contains only non
mandatory provision. This may contain mandatory statements such as when it can
be used, but the document as a whole is not suitable for adoption into law.
Recommended Practice
A document that is similar in content and structure to a code or standard but that
contains only non mandatory provisions using the word "should" to indicate
recommendations in the body of the text.
STANDARD
An NFPA document, the main text of which contains only mandatory provisions
using the word "shall" to indicate requirements and that is in a form generally
suitable for mandatory reference by another __________ or code or for adoption
into law.
Absolute Temperature
A temperature measured in Kelvins (K) or Rankines (R).
Accelerant A fuel or oxidizer, often an ignitible liquid, intentionally used to initiate a fire or
increase the rate of growth or spread of fire.
Accident
An unplanned event that interrupts an activity and sometimes causes injury or
damage or a chance occurrence arising from unknown causes; an unexpected
happening due to carelessness, ignorance, and the like.
Active Fire Protection System
A system that uses moving mechanical or electrical parts to achieve a fire
protection goal.
Ambient
Someone's or something's surroundings, especially as they pertain to the local
environment; for example, ambient air and ambient temperature.
Ampacity
The maximum current, in amperes, that a conductor can carry continuously under
the conditions of use without exceeding its temperature rating.
Ampere
The unit of electric current that is equivalent to a flow of one coulomb per second.
Arc
High-temperature luminous electric discharge across a gap or through a medium
such as charred insulation.
Arc Mapping
Identifying and documenting a fire pattern derived from the identification of arc
sites used to aid in determining the area of fire origin or spread.
Arc Melting Melting of conductors and conducting surfaces as a result of electrical arcing.
Arc Site
The location on a conductor with localized damage that resulted from an electrical
arc.
Arcing through Char
Arcing associated with a matrix of charred material that acts as a semiconductive
medium.
Area of Origin
A structure, part of a structure, or general geographic location within a fire scene,
in which the "point of origin" of a fire or explosion is reasonably believed to be
located.
Arrow Pattern
A fire pattern displayed on the cross-section of a burned wooden structural
member.
Arson
The crime of maliciously and intentionally, or recklessly, starting a fire or causing
an explosion.
Autoignition
Initiation of combustion by heat but without a spark or flame.
Autoignition Temperature
The lowest temperature at which a combustible material ignites in air without a
spark or flame.
Backdraft A deflagration resulting from the sudden introduction of air into a confined space
containing oxygen-deficient products of incomplete combustion.
Bead
A rounded mass of resolidified metal on the end of the remains of an electrical
conductor or conductors that was caused by arcing and is characterized by a sharp
line of demarcation between the melted and unmelted conductor surfaces.
Blast Pressure Front
The expanding leading edge of an explosion reaction that separates a major
difference in pressure between normal ambient pressure ahead of the front and
potentially damaging high pressure at and behind the front.
BLEVE
Boiling Liquid Expanding Vapor Explosion
Bonding
The permanent joining of metallic parts to form an electrically conductive path
that ensures electrical continuity and the capacity to conduct safely any current
likely to be imposed.
British Thermal Unit (BTU)
The quantity of heat required to raise the temperature of one pound of water 1
degree F at the pressure of 1 atmospheric and temperature of 60 degrees F.
Calcination of Gypsum
A fire effect realized in gypsum products, including wallboard, as a result of
exposure to heat that drives off free and chemically bound water.
Calorie
Amount of energy needed to raise temperature 1 gram of water 1 degree C
