that will clearly identify a chemical for the purpose of conducting an evaluation
F. IUPAC - CORRECT ANSWERS -International Union of Pure and Applied Chemistry
G. 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
H. Combustable liquid - CORRECT ANSWERS -any liquid that has a closed-cup flash
point at or above 100F, as determined by the standard test procedures
,I. Container - solid and liquid hazardous materials - CORRECT ANSWERS -a vessel of 60
gallons or less in capacity used for storage or transportation.
J. Container - compressed gases - CORRECT ANSWERS -a container pressure vessel or
tank designed for pressures greater than on atmosphere at 68F
K. What is not deemed a containers if in active use? - CORRECT ANSWERS -pipes, piping
systems, engines and engine fuel tanks associated with solid or liquid hazardous materials
or compressed gas
L. Corrosive material - CORRECT 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
M. 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
N. 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
O. Educational laboratory unit - CORRECT ANSWERS -a laboratory unit that is used for
educational purposes for students through the twelfth grade
P. 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
, Q. 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. Does not include a room provided
with general ventilation
R. 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
S. Explosions include the effects of the following sources: - CORRECT ANSWERS -1.
Chemical changes such as rapid oxidation, deflagration or detonation, decomposition of
molecules, and runaway polymerization
T. 2. Physical changes such as pressure tank ruptures
U. 3. Atomic changes (nuclear fission or fusion)
V. Face velocity - CORRECT 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
W. Fire separation - CORRECT ANSWERS -a horizontal or vertical fire resistance-rated
assembly of materials that have protected openings and are designed to restrict the spread
of fire
X. Flammable gas - CORRECT ANSWERS -any substance that exists in the gaseous state at
normal atmospheric temperature and pressure and is capable
