FDNY C-14 Exam Questions with
Complete Solutions
Basement - ANSWERS-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 - ANSWERS-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? - ANSWERS-20% evaporated
point of a distillation performed in accordance with ASTM D 86
Chemical - ANSWERS-an element, chemical compound, or mixture of elements or compounds
or both
Chemical name - ANSWERS-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 - ANSWERS-International Union of Pure and Applied Chemistry
Closed container - ANSWERS-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 - ANSWERS-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 - ANSWERS-a vessel of 60 gallons or less in
capacity used for storage or transportation.
Container - compressed gases - ANSWERS-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? - ANSWERS-pipes, piping systems, engines and
engine fuel tanks associated with solid or liquid hazardous materials or compressed gas
Corrosive material - ANSWERS-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 - ANSWERS-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 - ANSWERS-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 - ANSWERS-a laboratory unit that is used for educational purposes
for students through the twelfth grade
Excess flow control - ANSWERS-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 - ANSWERS-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 - ANSWERS-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: - ANSWERS-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 - ANSWERS-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 - ANSWERS-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 - ANSWERS-any substance that exists in the gaseous state at normal atmospheric
temperature and pressure and is capable
Flammable liquid - ANSWERS-any liquid that has a closed-cup flash point below 100F, as
determined by the standard test procedures
Flammable solid - ANSWERS-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
