CSP Exam Prep Questions And Answers
2026| A+ Guide Solution
Vapor - correct-answer -A gaseous form of a substance that is normally a solid or
liquid at room temperature.
Gas - correct-answer -Substances that completely occupy a space and can be
converted to a liquid or solid by increasing or decreasing temperature.
Vapor pressure - correct-answer -The pressure that a vapor at equilibrium with a
pure
liquid at a given temperature exerts to the surrounding atmosphere
Particulate - correct-answer -Fine solid or liquid particles, such as dust, fog, mist,
smoke,
or spray.
Dust - correct-answer -Solid particles generated by mechanical action (crushing,
grinding, etc.).

Size: 0.1 to 30 μm.
Fume - correct-answer -Airborne solid particles formed by condensation of vapor
(i.e., welding fumes).
Size: 0.001 to 1.0 μm.
Mist - correct-answer -Suspended liquid droplets generated by condensation or
atomization (fogs are formed by condensation).
Size: 0.01 to 10 μm.
Fiber - correct-answer -Particulate with an aspect ratio (length to width) of 3:1.
For Concentrations of gases and vapors:
STP is the standard temperature and
pressure of ___________________ - correct-answer -25°C and 1 atm
,3|Page
For physical sciences:
STP is equal to ______ - correct-answer -0°C and 1 atm
For ventilation:
STP is equal to ________ - correct-answer -70°F and 1 atm
PEL - correct-answer -Established by OSHA
The maximum exposure concentration to
a contaminant that an employee can be exposed to in an 8-h workday.
TLV - correct-answer -Established by ACGIH
The exposure time for various contaminants in an 8-h
workday.
*Not enforceable under law*
, 4|Page
TWA - correct-answer -the concentration that an employee is exposed to for a
specified period.
The PEL and TLV are both established for a TWA of 8 h.
TWA formula - correct-answer -TWA = (C1T1) + (C2T2) + (CnTn)/total hrs worked
Calculating PELs/TLVs for Periods Greater than 8 h - correct-answer -PEL n hrs =
PEL (or TLV) x 8hr/(actual shift worked in hrs)
OSHA Flammable Categories - correct-answer -
Category 1 - correct-answer -Flashpoint: <73.4f
Boiling Point: ≤95f
Category 2 - correct-answer -Flashpoint: <73.4f
Boiling Point: >95f
