CPC Safety, Quality Control & Risk Management 2 โ Questions and Answers
Question 1: Under OSHA's Hazard Communication Standard (HazCom), what document must accompany every hazardous chemical on a construction site?
- Job Safety Analysis (JSA)
- Safety Data Sheet (SDS) (Correct answer)
- Incident Report Form
- Material Requisition Form
Correct answer: Safety Data Sheet (SDS)
OSHA's HazCom Standard (29 CFR 1910.1200) requires Safety Data Sheets (SDS) to be available for each hazardous chemical used on site.
Question 2: A contractor uses a fishbone (Ishikawa) diagram during a quality investigation. What is the primary purpose of this tool?
- Schedule delay analysis
- Identifying root causes of a defect (Correct answer)
- Tracking inspection checklists
- Calculating rework costs
Correct answer: Identifying root causes of a defect
The Ishikawa (fishbone) diagram is a cause-and-effect tool used to identify root causes of quality defects by categorizing contributing factors.
Question 3: Which risk response strategy involves shifting the financial consequences of a risk to a third party, such as through insurance?
- Avoidance
- Mitigation
- Transfer (Correct answer)
- Acceptance
Correct answer: Transfer
Risk transfer moves the financial burden of a risk event to another partyโcommonly achieved through insurance, performance bonds, or contract indemnification clauses.
Question 4: In construction quality management, what does 'acceptance sampling' involve?
- Inspecting every unit before installation
- Testing a statistical subset of materials to infer overall batch quality (Correct answer)
- Accepting all materials from an approved vendor without inspection
- Reviewing shop drawings before fabrication
Correct answer: Testing a statistical subset of materials to infer overall batch quality
Acceptance sampling uses statistical methods to test a representative sample from a batch and decide whether to accept or reject the entire lot.
Question 5: What does the 'hierarchy of controls' prioritize as the MOST effective method to reduce workplace hazards?
- Personal Protective Equipment (PPE)
- Administrative controls
- Engineering controls
- Elimination of the hazard (Correct answer)
Correct answer: Elimination of the hazard
The hierarchy of controls ranks elimination (removing the hazard entirely) as the most effective control measure, with PPE being the least effective last resort.
Question 6: A project's risk register shows a risk with a probability of 0.4 and an impact of $50,000. What is the Expected Monetary Value (EMV)?
- $20,000 (Correct answer)
- $50,000
- $90,000
- $125,000
Correct answer: $20,000
EMV = Probability ร Impact = 0.4 ร $50,000 = $20,000, used in risk quantification and contingency reserve planning.
Question 7: Under OSHA 29 CFR 1926.502, what is the minimum height at which fall protection is required for construction workers on walking/working surfaces?
- 4 feet
- 6 feet (Correct answer)
- 8 feet
- 10 feet
Correct answer: 6 feet
OSHA 29 CFR 1926.502 requires fall protection for construction workers at heights of 6 feet or more above a lower level.
Under OSHA's Hazard Communication Standard (HazCom), what document must accompany every hazardous chemical on a construction site?
