of Hazardous Materials Practice Exam COMPLETE
QUESTIONS AND DETAILED SOLUTIONS LATEST
UPDATE THIS YEAR-JUST RELEASED.|BRAND NEW
BOILING POINT - ANSWER--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.
,MAXIMUM ALLOWABLE QUANTITY PER CONTROL
AREA - ANSWER--The maximum amount of a hazardous
material allowed to be stored, handled and/or used within
a control area inside a building or structure or an outdoor
control area.
NON-PRODUCTION LABORATORY - ANSWER--A
building or portion thereof wherein chemicals or gases are
stored, handled or used on a non-production basis for
testing, research, experimental, instructional or
educational purposes.
NORMAL TEMPERATURE AND PRESSURE (NTP) -
ANSWER--A temperature of 70°F and a pressure of 1
atmosphere.
, OUTDOOR CONTROL AREA - ANSWER--An outdoor
area that contains hazardous materials in amounts not
exceeding the maximum allowable quantities of Fire Code
Tables 2703.1.1(3) or 2703.1.1(4).
PERMISSIBLE EXPOSURE LIMIT (PEL) - ANSWER--The
maximum permitted 8-hour time-weighted average
concentration of an air-borne contaminant as established
by the regulations of the United States Department of
Labor, as set forth in 29 CFR Part 1910.1000, the
Recommended Exposure Limit (REL) concentrations
published by the U.S. National Institute for Occupational
Safety and Health (NIOSH), the Threshold Limit Value-
