FDNY C-14 EXAM QUESTIONS AND RIGHT
ANSWERS .
Basement ANS - a story partly below the grade plane and having less than one-half its clear height
(measured from finished floor to finished ceiling) below the grade plane
Boiling point ANS - the temperature at which the vapor pressure of a liquid equals the atmospheric
pressure of 14.7 PSI or 760 mm of mercury.
When a boiling point is unavailable for a material, what is used? ANS - 20% evaporated point of a
distillation performed in accordance with ASTM D 86
Chemical ANS - an element, chemical compound, or mixture of elements or compounds or both
Chemical name ANS - the scientific designation of a chemical in accordance with the nomenclature
system developed by the International Union of Pure and Applied Chemistry, the Chemical Abstracts
Service rules of nomenclature, or a name that will clearly identify a chemical for the purpose of
conducting an evaluation
IUPAC ANS - International Union of Pure and Applied Chemistry
Closed container ANS - a container sealed by means of a lid or other device capable of preventing the
escape of liquid, vapor, or dusts in the ordinary course of storage, handling, or use
Combustable liquid ANS - any liquid that has a closed-cup flash point at or above 100F, as determined
by the standard test procedures
Container - solid and liquid hazardous materials ANS - a vessel of 60 gallons or less in capacity used for
storage or transportation.
Container - compressed gases ANS - a container pressure vessel or tank designed for pressures greater
than on atmosphere at 68F
,What is not deemed a containers if in active use? ANS - pipes, piping systems, engines and engine fuel
tanks associated with solid or liquid hazardous materials or compressed gas
Corrosive material ANS - a liquid, solid, or gas that causes permanent injury ("full thickness
destruction") to human skin at a rate specified by the Department of Transportation regulations. Or a
liquid that can corrode 1/4in of steel or aluminum within a year
Design pressure ANS - the maximum gauge pressure that a pressure vessel, device, component, or
system is designed to withstand safely under the temperature and conditions of use
Dispensing ANS - the pouring or transferring by other means of any material from a container, tank, or
similar vessel, which would release dusts, fumes, mists, vapors, or gases to the atmosphere, unless such
release is prevented by a device, equipment, or system designed for that purpose
Educational laboratory unit ANS - a laboratory unit that is used for educational purposes for students
through the twelfth grade
Excess flow control ANS - a fail-safe system or other approved device, equipment or system designed to
shut off flow caused by a rupture in a pressurized piping system
Exhausted enclosure ANS - a device, typically consisting of a hood equipped with a fan that serves to
capture and exhaust fumes, mist, vapors, and gases generated at a workstation or other local
environment. Does not include a room provided with general ventilation
Explosion ANS - an effect produced by the sudden violent expansion of gases, whether or not
accompanied by a shock wave or disruption, of enclosing materials
Explosions include the effects of the following sources: ANS - 1. Chemical changes such as rapid
oxidation, deflagration or detonation, decomposition of molecules, and runaway polymerization
2. Physical changes such as pressure tank ruptures
, 3. Atomic changes (nuclear fission or fusion)
Face velocity ANS - the rate of flow or velocity of air moving into the chemical fume hood entrance or
face, as measure at the plane of the chemical fume hood face
Fire separation ANS - a horizontal or vertical fire resistance-rated assembly of materials that have
protected openings and are designed to restrict the spread of fire
Flammable gas ANS - any substance that exists in the gaseous state at normal atmospheric
temperature and pressure and is capable
Flammable liquid ANS - any liquid that has a closed-cup flash point below 100F, as determined by the
standard test procedures
Flammable solid ANS - A solid, other than a blasting agent or other explosive, whether in elemental or
alloy form, that is capable of causing a fire through friction, absorption of moisture, spontaneous
chemical change, or heat retained from manufacturing or processing, or which has an ignition
temperature below 212F or which burns so vigorously and persistently when ignited as to create a
serious hazard
Examples of flammable solids ANS - Aluminum powder
Camphor
Magnesium
Matches
Naphthalene
Nitrocellulose
Phosphorous
Sulfur
Picric acid
Flammable vapors/fumes ANS - The concentration of flammable constituents in air that exceeds 25
percent of their lower flammable limit (LFL)
