ALREADY GRADED A+
The dark char of the paper surface of gypsum wallboard, soot deposits and paint
can be ________ by continued flame exposure.
Deformation
Visible or measurable change in shape represented as bending, buckling, or
distortion of an item from heat or flame.
Discoloration
Materials that are increased in temperature, change phase, and are chemically
changed by exposure to heat often have this result to the effected surface.
Flame impact
,Maximum heat flux occurs at the area of _____ ______ and the fluxes are
reduced with increased distance.
Peak heat release rate
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.
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.
