NEWEST CERTIFIED SAFETY PROFESSIONAL
(CSP) EXAM OFFERED BY BOARD OF
CERTIFIED SAFETY PROFESSIONALS |
COMPLETE EXAM Q&A WITH RATIONALES
1. A safety professional is evaluating a chemical
process that uses a highly toxic intermediate. The
process is designed such that the toxic intermediate
is never present in the system at more than 5 gallons,
and it is immediately consumed in the next reaction
step. Which hierarchy of controls is being applied?
A) Substitution
B) Engineering controls (process intensification /
inherent safety)
C) Administrative controls
D) Personal protective equipment (PPE)
Correct answer: B
Rationale: Inherent safety (process intensification)
reduces the inventory of hazardous materials, which
is an engineering control. Substitution (A) would be
replacing the toxic chemical. This is a form of
inherent safety (minimization).
,2. A manufacturing facility has a machine with a point
of operation that requires frequent adjustment. A risk
assessment determines that the probability of a
serious injury is high. Which type of machine guard is
most appropriate for this situation?
A) Fixed guard (requires tool for removal)
B) Interlocked guard (prevents operation when guard
is open)
C) Adjustable guard (allows flexibility for different
workpiece sizes)
D) Self-adjusting guard (automatically adjusts to the
workpiece)
Correct answer: B
Rationale: An interlocked guard stops the machine
when the guard is opened, providing protection
during frequent adjustments. Fixed guard (A) is for
infrequent access. Adjustable (C) and self-adjusting
(D) guards may not provide adequate protection for
high-risk operations.
3. A safety professional is calculating the total
incident rate for a facility with 200 employees who
worked a total of 400,000 hours in a year. There were
10 recordable injuries (8 with days away from work, 2
without). What is the Total Recordable Incident Rate
(TRIR)?
,A) 2.5
B) 5.0
C) 10.0
D) 20.0
Correct answer: B
Rationale: TRIR = (Number of recordable injuries x
200,000) / total hours worked = (10 x 200,000) /
400,000 = 5.0. The 200,000 factor represents 100
employees working 40 hours/week for 50 weeks.
4. A confined space entry permit requires a gas test
before entry. The space previously contained
flammable liquids. Which of the following
atmospheric conditions is acceptable for entry
without respiratory protection?
A) Oxygen 19%, LEL 5%, H2S 10 ppm
B) Oxygen 21%, LEL 0%, CO 25 ppm
C) Oxygen 23%, LEL 10%, CO 50 ppm
D) Oxygen 18%, LEL 0%, H2S 0 ppm
Correct answer: B
Rationale: Confined space entry requires oxygen
19.5-23.5%, LEL <10% (or <5% for some standards),
and toxic substances below PEL. 21% O2 is
, acceptable, LEL 0% is safe, CO 25 ppm is below the
OSHA PEL of 50 ppm.
5. A chemical plant is designing a new storage tank
for a flammable liquid. The tank will be located inside
a diked area to contain spills. What is the primary
purpose of the dike (secondary containment)?
A) To prevent the tank from collapsing
B) To contain the contents of the tank in case of a
catastrophic failure or leak
C) To provide a walking surface for maintenance
workers
D) To reduce the evaporation rate of the liquid
Correct answer: B
Rationale: Secondary containment (dike, berm, or
curb) is designed to contain a spill or leak from the
primary container (tank) to prevent environmental
contamination and fire spread. The capacity must be
at least 110% of the largest tank's volume.
6. A safety professional is conducting a Job Safety
Analysis (JSA) for a task that involves lifting heavy
boxes onto a conveyor. Which step is the first in
conducting a JSA?
