AIEHS Certified Construction Health and Safety
CCHSP Exam
**Question 1.** Which leadership behavior most directly reinforces a “safety‑first” culture on a
construction site?
A) Offering financial bonuses for early project completion
B) Conducting daily toolbox talks that focus on hazard awareness
C) Delegating all safety decisions to subcontractors
D) Prioritizing client satisfaction over safety procedures
**Answer:** B
**Explanation:** Daily toolbox talks keep safety at the forefront of workers’ minds,
demonstrating management’s commitment to safety and reinforcing a safety‑first culture.
**Question 2.** In the Domino Theory of accident causation, which “domino” represents the
immediate cause of an accident?
A) Management decision
B) Unsafe act or condition
C) Accident‑producing environment
D) Personal factors
**Answer:** B
**Explanation:** The second domino (unsafe act or condition) is the immediate cause that
directly leads to the accident event.
**Question 3.** Who is primarily responsible for ensuring that all subcontractors on a site have
a current Site‑Specific Safety Plan (SSSP)?
A) The project’s safety officer
B) The site foreperson
C) The subcontractor’s own safety manager
D) The client’s representative
**Answer:** A
, AIEHS Certified Construction Health and Safety
CCHSP Exam
**Explanation:** The safety officer oversees the development, review, and implementation of
the SSSP for all parties on the site.
**Question 4.** Which element is NOT typically included in a Site‑Specific Safety Plan?
A) Hazard identification and control measures
B) Project budget breakdown
C) Emergency response procedures
D) Personal protective equipment (PPE) requirements
**Answer:** B
**Explanation:** A SSSP focuses on safety elements; financial budgeting is outside its scope.
**Question 5.** When implementing a fall‑protection system for work at heights, the “anchor
point” must have a minimum working load limit of:
A) 1 kN
B) 3 kN
C) 5 kN
D) 9 kN
**Answer:** D
**Explanation:** OSHA requires anchor points to support at least 5 kN (1,125 lb) for personal
fall arrest systems; many standards specify 9 kN (2,000 lb) for added safety.
**Question 6.** Which of the following is the most effective engineering control for preventing
falls from ladders?
A) Providing fall‑arrest harnesses to workers
B) Installing ladder‑specific guardrails
C) Using ladders with a slip‑resistant rungs and proper angle
, AIEHS Certified Construction Health and Safety
CCHSP Exam
D) Requiring daily ladder inspections
**Answer:** C
**Explanation:** Proper ladder design and use (angle, slip‑resistant rungs) eliminates the need
for personal fall arrest, making it the most effective control.
**Question 7.** A scaffold must be inspected:
A) Only before first use
B) Weekly, regardless of use
C) Before each shift and after any alteration or incident
D) Only when a worker reports a defect
**Answer:** C
**Explanation:** Scaffolds require a pre‑shift inspection and additional checks after any
change, damage, or incident to ensure ongoing safety.
**Question 8.** The maximum load capacity of a standard wooden scaffold platform is
typically:
A) 500 kg per square meter
B) 1,000 kg per square meter
C) 2,000 kg per square meter
D) 4,000 kg per square meter
**Answer:** B
**Explanation:** Most codes set a standard scaffold platform load limit of 2 kN/m²
(≈ 200 kg/m²) for live load, equating to about 1,000 kg for a 5 m² area.
**Question 9.** Which soil type is considered the most unstable for trenching and requires
shoring or shielding?
A) Type A (granular, dry)
, AIEHS Certified Construction Health and Safety
CCHSP Exam
B) Type B (cohesive, slightly weathered)
C) Type C (highly organic, soft)
D) Type D (rock)
**Answer:** C
**Explanation:** Type C soils are weak, highly susceptible to collapse, and must be protected
with shoring or shielding.
**Question 10.** The “sloping” method for trench protection is most appropriate when the
slope angle is:
A) 30° for all soil types
B) 45° for Type A soils only
C) 60° for Type B soils only
D) 70° for Type C soils only
**Answer:** B
**Explanation:** A 45° slope is generally acceptable for Type A (stable) soils; steeper slopes are
required for less stable soils.
**Question 11.** When operating a mobile crane, the “load chart” is used to determine:
A) The crane’s fuel consumption rate
B) The maximum permissible load at a given boom length and radius
C) The crane’s maintenance schedule
D) The operator’s certification level
**Answer:** B
**Explanation:** The load chart provides the safe lifting capacity based on boom length, radius,
and configuration.
