CRC Risk Management & Site Safety 2 — Questions and Answers
Question 1: Under OSHA's Hazard Communication Standard (HCS), what document must be available on-site for every hazardous chemical used by workers?
- Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS) (Correct answer)
- Chemical Use Permit issued by the EPA
- Contractor's chemical inventory log signed by the owner
- OSHA Form 300 listing chemical exposures
Correct answer: Material Safety Data Sheet (MSDS) or Safety Data Sheet (SDS)
OSHA's HCS (29 CFR 1910.1200) requires Safety Data Sheets (SDS, formerly MSDS) to be readily accessible to workers for every hazardous chemical present on the job site.
Question 2: A residential contractor is excavating a trench 6 feet deep. According to OSHA, what protective system is REQUIRED?
- Sloping, shoring, or trench box/shield (Correct answer)
- Warning tape placed 2 feet from the trench edge
- A licensed engineer on-site at all times
- Daily soil moisture testing and documentation
Correct answer: Sloping, shoring, or trench box/shield
OSHA 29 CFR 1926.652 requires a protective system (sloping, shoring, or a trench box/shield) for all excavations 5 feet deep or greater.
Question 3: Which type of insurance covers third-party bodily injury and property damage claims arising from a contractor's completed operations?
- Products and Completed Operations Liability (Correct answer)
- Workers' Compensation Insurance
- Builder's Risk Insurance
- Inland Marine Insurance
Correct answer: Products and Completed Operations Liability
Products and Completed Operations Liability, a component of general liability policies, covers claims arising after a project is finished if the work caused injury or damage.
Question 4: What is the primary purpose of a Job Hazard Analysis (JHA) on a residential construction site?
- To identify and control hazards for each job task before work begins (Correct answer)
- To document accidents after they occur for OSHA recordkeeping
- To determine the bid price based on risk factors
- To assign liability between subcontractors on a shared site
Correct answer: To identify and control hazards for each job task before work begins
A Job Hazard Analysis proactively identifies potential hazards associated with specific tasks so controls can be implemented before workers are exposed.
Question 5: Under a contractor's general liability policy, what term describes the maximum the insurer will pay for all claims during the policy period?
- Aggregate limit (Correct answer)
- Per-occurrence limit
- Retention limit
- Umbrella threshold
Correct answer: Aggregate limit
The aggregate limit is the total maximum payout the insurer will provide for all covered claims combined during the policy period.
Question 6: A subcontractor's employee is injured on a residential job site. If the subcontractor lacks workers' compensation insurance, who typically bears the liability?
- The general contractor, as the controlling employer (Correct answer)
- The property owner, as the site host
- The injured worker bears their own costs
- OSHA assumes financial responsibility
Correct answer: The general contractor, as the controlling employer
When a subcontractor lacks workers' compensation coverage, many states hold the general contractor (as the controlling employer) liable for the injured worker's benefits.
Question 7: What is a 'toolbox talk' in residential construction site safety?
- A brief, informal safety meeting held at the job site to discuss hazards relevant to upcoming work (Correct answer)
- A formal OSHA-mandated weekly safety training session requiring sign-off
- A written safety plan submitted to the building department before work begins
- An equipment inspection checklist completed by operators daily
Correct answer: A brief, informal safety meeting held at the job site to discuss hazards relevant to upcoming work
Toolbox talks are short, informal safety discussions led by supervisors at the job site to address specific hazards before or during work activities.
