CCM Construction Safety and Risk 5 — Questions and Answers
Question 1: In the context of construction risk, 'force majeure' events are best described as:
- Risks caused by contractor negligence
- Unforeseeable events beyond the parties' control that excuse contract performance (Correct answer)
- Delays resulting from subcontractor default
- Owner-directed changes to the project scope
Correct answer: Unforeseeable events beyond the parties' control that excuse contract performance
Force majeure clauses excuse non-performance due to extraordinary, unforeseeable events such as natural disasters, wars, or pandemics that are beyond either party's control.
Question 2: A construction manager conducting a pre-task safety briefing (toolbox talk) is fulfilling which function of a safety management system?
- Corrective action tracking
- Hazard communication and worker engagement (Correct answer)
- Incident investigation
- Regulatory compliance auditing
Correct answer: Hazard communication and worker engagement
Toolbox talks serve as a hazard communication and worker engagement tool, connecting safety planning to frontline workers before tasks begin.
Question 3: Which OSHA standard requires construction employers to implement a written Hazard Communication Program when workers are exposed to hazardous chemicals?
- 29 CFR 1926.59 (Correct answer)
- 29 CFR 1926.502
- 29 CFR 1926.650
- 29 CFR 1926.1101
Correct answer: 29 CFR 1926.59
29 CFR 1926.59 (the construction HazCom standard) requires written programs, SDS access, labeling, and worker training on chemical hazards.
Question 4: A construction manager is evaluating insurance coverage for a major vertical project. Which policy covers physical loss or damage to the structure under construction?
- Commercial General Liability (CGL)
- Builders Risk (Course of Construction) insurance (Correct answer)
- Professional Liability (E&O) insurance
- Workers' Compensation insurance
Correct answer: Builders Risk (Course of Construction) insurance
Builders Risk insurance covers the physical structure, materials, and equipment on site for damage during the construction period.
Question 5: When performing a root cause analysis after a construction incident, which method uses repeated 'why' questions to trace a problem to its fundamental cause?
- Fault tree analysis (FTA)
- 5 Whys technique (Correct answer)
- Failure Mode and Effects Analysis (FMEA)
- Bowtie analysis
Correct answer: 5 Whys technique
The 5 Whys technique iteratively asks 'why' until the root cause is identified, typically reaching the systemic or management failure behind the incident.
Question 6: Under OSHA's scaffolding standard (29 CFR 1926 Subpart L), the maximum permissible deflection for a scaffold plank is:
- 1/30 of the span
- 1/60 of the span (Correct answer)
- 1/90 of the span
- 1/120 of the span
Correct answer: 1/60 of the span
OSHA requires scaffold planks to have sufficient strength so that deflection does not exceed 1/60 of the span under maximum intended load.
Question 7: A construction manager reviewing a subcontractor's safety record notes an EMR of 1.45. This figure indicates the subcontractor's workers' compensation losses are:
- 45% below the industry average
- 45% above the industry average (Correct answer)
- 1.45 times below expected losses
- At the industry average with a 45% safety incentive credit
Correct answer: 45% above the industry average
An EMR above 1.0 means actual losses exceed the industry average; 1.45 indicates losses are 45% higher than the expected industry baseline.
