CCM Construction Safety and Risk Questions and Answers — Questions and Answers
Question 1: During a daily site inspection, a Construction Manager observes a subcontractor's crew working on a scaffold that is over 10 feet high but lacks a complete guardrail system. According to OSHA's 'Focus Four' hazards, this situation represents a failure to protect against which type of hazard?
- Struck-By
- Caught-In/Between
- Falls (Correct answer)
- Electrocution
Correct answer: Falls
OSHA's 'Focus Four' hazards are responsible for the majority of fatalities in construction. The lack of a proper guardrail system on an elevated platform directly exposes workers to the risk of falling, which is one of the most common and severe construction hazards.
Question 2: A CCM is developing a risk management plan for a project involving deep excavation next to an existing historic building. The team identifies a high-impact, low-probability risk of the excavation causing structural damage to the adjacent building. Which of the following would be the most appropriate risk response strategy?
- Accept the risk and create a contingency fund for potential repairs.
- Mitigate the risk by implementing a robust shoring system and continuous structural monitoring. (Correct answer)
- Avoid the risk by redesigning the project to eliminate the deep excavation entirely.
- Ignore the risk because its probability of occurrence is very low.
Correct answer: Mitigate the risk by implementing a robust shoring system and continuous structural monitoring.
Mitigation is the most appropriate strategy for a high-impact risk, even if the probability is low. While accepting the risk with a contingency fund is a possibility, it does not actively reduce the likelihood of the catastrophic event. Mitigation, through proactive measures like enhanced shoring and monitoring, directly addresses and reduces the risk to the historic building.
Question 3: To proactively improve safety culture and prevent future incidents, a project's safety manager is tracking several metrics. Which of the following is the best example of a 'leading indicator' of safety performance?
- The project's Experience Modification Rate (EMR) for the past year.
- The number of near-misses reported and investigated in the current month. (Correct answer)
- The total number of OSHA recordable incidents from the previous quarter.
- The cost of workers' compensation claims filed to date.
Correct answer: The number of near-misses reported and investigated in the current month.
Leading indicators are proactive, preventative measures that track activities designed to prevent future incidents. Reporting and investigating near-misses is a leading indicator because it identifies and corrects hazards before they result in an actual injury. EMR, recordable incidents, and compensation costs are all 'lagging indicators' because they measure failures and outcomes that have already occurred.
Question 4: An excavation on a construction site is planned to be 15 feet deep in Type B soil. According to OSHA standards (29 CFR 1926 Subpart P), who is required to conduct daily inspections of the excavation, adjacent areas, and protective systems for evidence of potential cave-ins or other hazards?
- The project's Quality Control Manager
- The third-party Geotechnical Engineer
- A 'Competent Person' designated by the employer (Correct answer)
- The on-site Project Superintendent
Correct answer: A 'Competent Person' designated by the employer
OSHA regulations specifically mandate that a 'Competent Person' must conduct daily inspections of excavations. A competent person is defined as one who is capable of identifying existing and predictable hazards in the surroundings or working conditions which are unsanitary, hazardous, or dangerous to employees, and who has authorization to take prompt corrective measures to eliminate them.
Question 5: A contractor is preparing a Job Hazard Analysis (JHA) for the task of erecting structural steel. What is the primary purpose of this document?
- To satisfy the owner's insurance carrier requirements.
- To pre-qualify the crane operator for the specific lifts.
- To calculate the final cost of the steel erection activity.
- To identify potential hazards for each step of the task and establish controls to mitigate them. (Correct answer)
Correct answer: To identify potential hazards for each step of the task and establish controls to mitigate them.
The primary purpose of a Job Hazard Analysis (also known as a Job Safety Analysis or JSA) is to systematically break down a task into its constituent steps, identify the associated hazards at each step, and prescribe specific controls, procedures, or personal protective equipment (PPE) to eliminate or reduce the risk of those hazards.
Question 6: A serious incident occurs on-site, resulting in an employee fatality. After securing the scene and reporting the incident to OSHA within the required timeframe, the CCM initiates an incident investigation. What is the ultimate goal of conducting a root cause analysis as part of this investigation?
- To assign blame to the responsible individual or subcontractor.
- To complete the required paperwork for the insurance claim.
- To determine the direct cause of the injury for the OSHA 300 log.
- To identify underlying system failures and implement changes to prevent recurrence. (Correct answer)
Correct answer: To identify underlying system failures and implement changes to prevent recurrence.
While identifying the direct cause is part of the process, the ultimate goal of a root cause analysis is to look beyond the immediate error and identify the underlying systemic failures in management, training, procedures, or equipment that allowed the incident to happen. Addressing these root causes is the only effective way to prevent similar incidents from recurring in the future.
