COF C-91 Exam with all Correct & 100% Verified Answers
|Latest Version |Already Graded A+
BOILING POINT ✔Correct Answers-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.
CEILING LIMIT ✔Correct Answers-The maximum concentration of an airborne contaminant to
which one may be exposed shall be as established by the regulations of the United States
Department of Labor, as set forth in 29 CFR Part 1910.1000, or if not listed therein, the ceiling
Recommended Exposure Limit (REL-C) concentrations published by the U.S. National Institute
for Occupational Safety and Health (NIOSH), the Threshold Limit Value — Ceiling (TLV-C)
concentrations published by the American Conference of Governmental Industrial Hygienists
(ACGIH), the ceiling Workplace Environmental Exposure Level (WEEL-Ceiling) Guides published
by the American Industrial Hygiene Association (AIHA), or other approved standard.
CHEMICAL ✔Correct Answers-An element, chemical compound or mixture of elements or
compounds or both.
CHEMICAL NAME ✔Correct 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.
CLOSED CONTAINER ✔Correct 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.
CONTAINER ✔Correct Answers-For solid and liquid hazardous materials, a vessel of 60 gallons
or less in capacity used for storage or transportation. For compressed gases, a cylinder, 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.
CONTAINMENT SYSTEM ✔Correct Answers-A gas-tight recovery system comprised of devices
or equipment which, when placed over or around the portion of the compressed gas container
that is leaking, stops or controls the escape of gas from the container.
, CONTAINMENT VESSEL ✔Correct Answers-A gas-tight vessel which, when installed or placed
over or around a leaking compressed gas container, confines the container and the gas leaking
there from.
CONTROL AREA ✔Correct Answers-Spaces within a building that are enclosed and bounded
by exterior walls, fire walls, fire barriers and roofs, or a combination thereof, where quantities of
hazardous materials not exceeding the maximum allowable quantities per control area are
stored, handled or used, including any dispensing.
DESIGN PRESSURE ✔Correct 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.
DETACHED BUILDING ✔Correct Answers-A separate single-story building, without a basement
or crawl space, used for the storage, handling or use of hazardous materials and located an
approved distance from other buildings or structures.
DISPENSING ✔Correct 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.
EXCESS FLOW CONTROL ✔Correct 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 ✔Correct 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. An exhausted enclosure does not include a room
provided with general ventilation.
EXOTHERMIC ✔Correct Answers-A process or reaction that releases energy usually in the
form of heat, but also in form of light e.g. a spark, flame, or explosion.
EXPLOSION ✔Correct Answers-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 chemical, physical, and atomic sources.
FLAMMABLE VAPORS OR FUMES ✔Correct Answers-The concentration of flammable
constituents in air that exceeds 25 percent of their lower flammable limit (LFL).
GAS CABINET ✔Correct Answers-A fully enclosed, noncombustible enclosure used to provide
an isolated environment for compressed gas containers in storage or use, including any doors
and access ports for exchanging containers and accessing pressure-regulating controls.
