FDNY C-14 Exam: SUPERVISION OF
STORAGE, HANDLING AND USE OF
CHEMICALS IN NON-PRODUCTION
LABORATORIES
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 pounds per square inch (psia) or 760 mm of mercury. Where a
boiling point is unavailable for the material in question or for mixtures which do not have a
constant boiling point, for the purposes of this classification, the 20- percent evaporated point of
a distillation performed in accordance with ASTM D 86 shall be used as the boiling point of the
liquid.
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
(IUPAC), the Chemical Abstracts Service rules of nomenclature, or a name that will clearly
identify a chemical for the purpose of conducting an evaluation.
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.
COMBUSTIBLE LIQUID - ANS-Any liquid that has a closed-cup flash point at or above 100°F,
as determined by the standard test procedures.
CONTAINER - ANS-For solid and liquid hazardous materials, a vessel of 60 gallons or less in
capacity used for storage or transportation. For compressed gases, a container, pressure vessel
or tank designed for pressures greater than one atmosphere at 68°F. Pipes, piping systems,
engines and engine fuel tanks associated with solid or liquid hazardous materials or
compressed gases, shall not be deemed to be containers if in active use.
, CORROSIVE MATERIALS - 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
(DOT) regulations. Or a liquid that can corrode 1⁄4 inch of steel or aluminum within the course of
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.
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. An exhausted enclosure 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, including the effects of
the following sources of explosion:
1. Chemical changes such as rapid oxidation, deflagration or detonation, decomposition of
molecules and runaway polymerization (usually detonations).
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 measured 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 of being ignited and burned when mixed
with the proper proportions of air, oxygen, or other oxidizers.
FLAMMABLE LIQUID - ANS-Any liquid that has a closed-cup flash point below 100°F, as
determined by the standard test procedures.
