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