CSP COMPREHENSIVE TEST 2026 QUESTIONS
ANSWERS VERIFIED
◉ How long does it take the ears to recover from brief exposure to
loud noise. Answer: More than one hour
◉ On average, more than X people suffer eye injuries per day..
Answer: 2,000
◉ Which is a cause of eye strain in the workplace. Answer: Poor
lighting and excessive glare
◉ [Noise Hazard Reduction Methods] Elimination. Answer: Remove
the noise source
◉ [Noise Hazard Reduction Methods] Substitution. Answer: Replace
loud machinery with quieter alternatives
◉ [Noise Hazard Reduction Methods] Modification. Answer:
Redesign or alter equipment to REDUCE NOISE OUTPUT
,◉ [Noise Hazard Reduction Methods] Retrofit. Answer: Add noise-
dampening features to existing equipment (e.g. silencers, vibration
isolators)
◉ [Noise Hazard Reduction Methods] Enclosure. Answer: Surround
the noise source with soundproof materials
◉ [Noise Hazard Reduction Methods] Rotation and Scheduling.
Answer: Limit worker exposure time to high-noise areas
◉ [Noise Hazard Reduction Methods] Distance. Answer: Increase the
distance between workers and noise sources
◉ [Noise Hazard Reduction Methods] Maintenance. Answer: Keep
equipment in good condition to prevent excessive noise
◉ [Noise Hazard Reduction Methods] Hearing Protection. Answer:
Use earplugs and earmuffs when all other controls are insufficient
◉ What are the purposes of industrial ventilation?. Answer:
Contaminant control (removes or dilutes airborne hazards to
maintain safe air quality); Temperature and humidity regulation
(maintains safe and comfortable conditions); and Fire and explosion
prevention (controls flammable and explosive vapors and dust)
,◉ Local Exhaust Ventilation (LEV). Answer: Function: Captures
contaminants at or near the source before they can disperse
Components: Hoods, ducts, air cleaners, fans, and exhaust stacks
Applications: Welding fumes, chemical vapors, and dust from
grinding operations
◉ Dilution (or General) Ventilation. Answer: Function: Dilutes
contaminated air with fresh air to reduce contaminant
concentrations
Applications: Controlling low-toxicity vapors or odors released over
large areas
Limitations: Not effective for highly toxic substances or localized
contaminant sources
◉ [Key Ventilation Components] Hoods. Answer: Capture
contaminants, designs include enclosures, receiving and capturing
types
◉ [Key Ventilation Components] Ducts. Answer: Transport air and
contaminants; proper sizing and layout are essential to minimize
resistance and prevent settling
◉ [Key Ventilation Components] Air Cleaners. Answer: Remove
contaminants from the air stream before discharge or recirculation;
also known as scrubbers or filters
, ◉ [Key Ventilation Components] Fans. Answer: Provide the
necessary energy to move air through the system; centrifugal and
axial types
◉ [Key Ventilation Components] Stacks/Exhaust Outlets. Answer:
Discharge cleaned air into the atmosphere; height and location are
important to prevent reentry into the workplace
◉ [Airflow Principles] Airflow Measurement. Answer: Utilizes
instruments like anemometers and pitot tubes to assess system
performance
◉ [Airflow Principles] Static Pressure. Answer: The potential energy
in the system; this must be managed to ensure efficient airflow
◉ [Airflow Principles] Velocity Pressure. Answer: The kinetic energy
of moving air; influences the transport of contaminants
◉ [Airflow Principles] Total Pressure. Answer: The sum of static and
velocity pressures; this is used in system design and evaluation
◉ [Airflow Design Considerations] Capture Velocity. Answer: The
airspeed necessary at the hood opening to effectively capture
contaminants
