CCM Construction Safety and Risk 4 — Questions and Answers
Question 1: The Experience Modification Rate (EMR) primarily reflects a company's:
- OSHA inspection history
- Workers' compensation claims history relative to industry peers (Correct answer)
- Number of safety training hours completed annually
- Compliance with ANSI standards
Correct answer: Workers' compensation claims history relative to industry peers
EMR compares a company's actual workers' compensation losses to the expected losses for its industry, affecting insurance premiums.
Question 2: During a crane lift near energized overhead power lines, OSHA requires the minimum clearance distance for lines rated up to 50 kV to be:
- 5 feet
- 10 feet (Correct answer)
- 15 feet
- 25 feet
Correct answer: 10 feet
OSHA 29 CFR 1926.1408 requires at least 10 feet of clearance from power lines up to 50 kV during crane operations.
Question 3: A contractor discovers an unexpected utility strike during excavation. The BEST immediate response is to:
- Continue work carefully and note it in the daily log
- Stop work, evacuate the area, and notify the utility owner and emergency services if damaged (Correct answer)
- Cover the exposed utility and resume work
- Reassign workers and document in the next safety meeting
Correct answer: Stop work, evacuate the area, and notify the utility owner and emergency services if damaged
An unexpected utility strike requires immediate work stoppage, area evacuation, and notification of the utility owner and emergency services if the line is damaged.
Question 4: Which of the following is a leading safety indicator rather than a lagging indicator?
- Total recordable incident rate (TRIR)
- Number of near-miss reports submitted per month (Correct answer)
- Lost time injury frequency rate (LTIFR)
- Workers' compensation cost per incident
Correct answer: Number of near-miss reports submitted per month
Near-miss reporting rates are leading indicators that measure proactive safety activity before incidents occur.
Question 5: Under the CM's risk management role, which contract clause best protects the owner from contractor-caused third-party bodily injury claims?
- Liquidated damages clause
- Force majeure clause
- Additional insured endorsement on contractor's CGL policy (Correct answer)
- No-damage-for-delay clause
Correct answer: Additional insured endorsement on contractor's CGL policy
An additional insured endorsement extends the contractor's Commercial General Liability coverage to the owner for third-party claims arising from the contractor's work.
Question 6: What is the primary goal of a Safety Management System (SMS) on a construction project?
- Ensure OSHA citations are minimized through documentation
- Integrate safety into all project processes to systematically prevent incidents (Correct answer)
- Transfer liability to subcontractors through contractual terms
- Meet minimum insurance carrier requirements for premium reduction
Correct answer: Integrate safety into all project processes to systematically prevent incidents
An SMS embeds safety into project planning, execution, and monitoring processes to proactively prevent injuries and losses.
Question 7: Silica dust exposure on a construction site is regulated under OSHA standard 29 CFR 1926.1153. The permissible exposure limit (PEL) for respirable crystalline silica is:
- 250 µg/m³ as an 8-hour TWA
- 100 µg/m³ as an 8-hour TWA
- 50 µg/m³ as an 8-hour TWA (Correct answer)
- 10 µg/m³ as an 8-hour TWA
Correct answer: 50 µg/m³ as an 8-hour TWA
OSHA's silica rule sets the PEL at 50 µg/m³ as an 8-hour time-weighted average for construction activities.
