ASP Exam Study Set| 685 Practice Questions with
Complete Solutions| Verified Answers| 2024-25
activated carbon - ✔✔A form of specially treated, porous carbon, used to absorb various
odors and vapors. Has a non-polar surface.
Axial flow fans - ✔✔High volume and low pressure drop; general & dilution ventilation; NOT
good for LEV; NOT used to move air through a duct; sometimes used for comfort.
Centrifugal fans - ✔✔Fan axis is perpendicular to flow -- spits air out 90 degrees. Low noise.
Suited to high pressures. Low to moderate static pressures; used in heating & air conditioning;
workhorse of industrial hygiene; sometimes called squirrel cages; good for lint, wood chips &
dust.
Forward blades in centrifugal fan - ✔✔Blades are curved in the direction of rotation. Used
whenever a large air volume has to be moved in a tight space. Requires more power, which can
overload motors.
Backward blades in centrifugal fan - ✔✔Blades are curved in the opposite direction of
rotation. More efficient than forward blades.
Paddle wheel or long-shaving wheel - ✔✔Used with medium tip speed for buffing exhaust,
woodworking exhaust or when heavy dust must pass through the fan.
Max travel distance of fire extinguisher in light hazard occupancies - ✔✔75 ft. Includes
places like churches, clubs, education centers, kennels, museums, homes.
Inspection items for self-closing doors - ✔✔1) Lubrication on guides & bearings
2) Binders are not bent, thus obstructing door
,3) Chains/wire ropes have not stretched.
4) Fusible links are NOT painted.
Main cause of sprinkler system failure - ✔✔35% of the time: closed water-supply valves.
Main cause of leaking sprinkler heads - ✔✔Overheating from being too close to heat-
generating processes.
How often should sound level meters be calibrated? - ✔✔Before & after each survey
Particle sizes - ✔✔Large: silica
Small: zinc
Safest method to determine electrical current - ✔✔Split-core ammeter
Treating exposure to liquid oxygen - ✔✔Warm water. Never rub or use dry heat. Frozen
tissue is painless but will be swollen & painful when thawed.
Required languages for HAZCOM - ✔✔Only English. Others can be used in addition, but only
English is required.
TTS - ✔✔temporary threshold shift. Will experience a transient attenuation.
PTS - ✔✔permanent threshold shift. One theory is that these result from many TTSs.
Butyl/neoprene gloves - ✔✔Gloves that made of a synthetic rubber and protect against wide
variety of chemicals -- acids, bases.
,3 components of every noise problem - ✔✔Source, path, receiver
Training requirements for HAZWOPER - ✔✔site workers, spill response, PPE
TLV - ✔✔Threshold Limit Value. All employees can be exposed daily without adverse health
effects.
Autoignition Temperature - ✔✔The lowest temperature at which a combustible material
ignites in air without a spark or flame.
Rules on Danger Tags under 1910.145 (accident prevention signs & tags) - ✔✔1) Readable at
5 ft
2) Must use words, pictures or both.
3) As close as possible to the hazard.
4) Employees must be informed on sign meanings.
5) Positive, concise, standardized.
Hierarchy of Safety and Health Controls - ✔✔1) Elimination
2) Substitution
3) Engineering Controls (ex. LEV)
4) Warnings/Administrative (ex. LOTO, work/rest)
5) Personal Protective Equipment
ANSI Z10 puts Warnings as #4 and Admin as #5
Thermal vane anemometer - ✔✔Used where exhaust opening is large, air velocities are low -
-> spray booths or chemical hoods. Heated probe that senses velocity by the amount of heat
removed from the probe. Direct reading & accurate.
, Rotating vane anemometer - ✔✔Useful for measuring the airflow through large supply and
exhaust openings where the air velocities are relatively high.
Components measured in industrial effluents - ✔✔biochemical oxygen demand, total
suspended solids, metal content, temperature.
NPDES - ✔✔National Pollutant Discharge Elimination System (EPA permit)
Slot hoods - ✔✔Used to provide uniform exhaust airflow (e.g., over tank suface). Function is
to obtain proper air distribution. (Note: Capture velocity involves exhaust volume and slot
length but NOT slot velocity.)
Vapor pressure - ✔✔Pressure exerted by a vapor that is in equilibrium with the liquid at a
given temperature; the ability of the liquid to evaporate.
Static friction - ✔✔the force that resists the initiation of sliding motion between two
surfaces that are in contact and at rest
kinetic friction - ✔✔the force that opposes the movement of two surfaces that are in contact
and are moving over each other. Not affected by speed.
Is friction (static or kinetic) affected by the amount of surface area? - ✔✔No
Number of states that have OSHA-approved state plans - ✔✔25 (plus Puerto Rico & Virgin
Islands)
OSHA's jurisdiction - ✔✔Most private employers & workers.
NOT COVERED: self-employed, immediately family farm workers, state & local government
employees; workers regulated by other government agencies.
