Nafi Cfei Official Exam Graded A+

CODE - Answer 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 - Answer 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 - Answer 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 - Answer 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 - Answer A temperature measured in Kelvins (K) or Rankines (R). Accelerant - Answer 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 - Answer 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 - Answer A system that uses moving mechanical or electrical parts to achieve a fire protection goal. Ambient - Answer Someone's or something's surroundings, especially as they pertain to the local environment; for example, ambient air and ambient temperature. Ampacity - Answer The maximum current, in amperes, that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Ampere - Answer The unit of electric current that is equivalent to a flow of one coulomb per second. Arc - Answer High-temperature luminous electric discharge across a gap or through a medium such as charred insulation.Arc Mapping - Answer 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 - Answer Melting of conductors and conducting surfaces as a result of electrical arcing. Arc Site - Answer The location on a conductor with localized damage that resulted from an electrical arc. Arcing through Char - Answer Arcing associated with a matrix of charred material that acts as a semiconductive medium. Area of Origin - Answer 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 - Answer A fire pattern displayed on the cross-section of a burned wooden structural member. Arson - Answer The crime of maliciously and intentionally, or recklessly, starting a fire or causing an explosion. Autoignition - Answer Initiation of combustion by heat but without a spark or flame. Autoignition Temperature - Answer The lowest temperature at which a combustible material ignites in air without a spark or flame. Backdraft - Answer A deflagration resulting from the sudden introduction of air into a confined space containing oxygen-deficient products of incomplete combustion. Bead - Answer 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 - Answer 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 - Answer Boiling Liquid Expanding Vapor Explosion Bonding - Answer 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) - Answer 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.
