CHST CHST - Construction Health and Safety Technician Safety Program Management Questions and Answers 5 — Questions and Answers
Question 1: A project safety manager is developing a subcontractor prequalification process. Which criterion is MOST relevant to safety program effectiveness?
- Number of employees on the subcontractor's payroll
- Subcontractor's three-year TRIR and DART rates compared to industry averages (Correct answer)
- Whether the subcontractor uses union or non-union labor
- The subcontractor's proximity to the project site
Correct answer: Subcontractor's three-year TRIR and DART rates compared to industry averages
TRIR and DART rates provide objective, industry-benchmarked evidence of a subcontractor's historical safety performance.
Question 2: Which approach BEST ensures that lessons learned from a serious incident are communicated effectively across all crews on a large construction site?
- Posting a written summary on the safety bulletin board
- Sending an email to all supervisors with incident details
- Conducting structured safety stand-downs with interactive discussion at each crew level (Correct answer)
- Updating the project safety plan and filing it with HR
Correct answer: Conducting structured safety stand-downs with interactive discussion at each crew level
Interactive stand-downs with each crew ensure two-way communication, comprehension, and direct application of lessons to specific work tasks.
Question 3: What is the primary legal significance of maintaining accurate OSHA 300 logs on a construction project?
- They establish the basis for calculating workers' compensation premiums directly
- They provide OSHA with data to establish industry injury and illness benchmarks and support enforcement (Correct answer)
- They replace the need for written incident investigation reports
- They allow the employer to avoid penalties for first-time violations
Correct answer: They provide OSHA with data to establish industry injury and illness benchmarks and support enforcement
OSHA 300 logs are required records used by OSHA for enforcement, data collection, and industry-wide injury and illness benchmarking.
Question 4: A safety technician is tasked with selecting a leading indicator to track daily. Which choice provides the MOST actionable real-time safety data?
- Monthly lost-time injury frequency rate
- Daily percentage of pre-task planning forms completed before work begins (Correct answer)
- Quarterly workers' compensation experience modification rate (EMR)
- Annual OSHA recordable incident rate
Correct answer: Daily percentage of pre-task planning forms completed before work begins
Daily pre-task planning completion rates are a leading indicator that directly measures whether workers are identifying hazards before starting work.
Question 5: Which scenario represents a failure of the 'management of change' (MOC) process on a construction site?
- A new subcontractor is added mid-project without updating the site safety plan or briefing workers on new hazards (Correct answer)
- A competent person re-inspects scaffolding after a rain event before work resumes
- A supervisor holds a toolbox talk when crew composition changes for a day
- A JHA is revised when a new piece of equipment is introduced
Correct answer: A new subcontractor is added mid-project without updating the site safety plan or briefing workers on new hazards
Adding a subcontractor without updating the safety plan or notifying workers is a classic MOC failure — changes must trigger a hazard review process.
Question 6: Under OSHA's Hazard Communication Standard (HazCom 2012 / GHS), what training must workers receive when a new chemical hazard is introduced to the workplace?
- Training on the new hazard must be provided before workers are exposed to it (Correct answer)
- Training may be deferred until the next scheduled quarterly safety meeting
- Workers need only be directed to read the SDS independently
- Training is required only if the chemical has an IDLH concentration
Correct answer: Training on the new hazard must be provided before workers are exposed to it
HazCom requires that workers receive training on new chemical hazards before exposure, ensuring informed protection from the outset.
Question 7: A safety program manager wants to improve supervisor accountability for safety. Which mechanism is MOST effective for embedding safety into supervisor performance expectations?
- Requiring supervisors to attend monthly safety committee meetings
- Including measurable safety performance metrics in supervisor performance reviews and compensation (Correct answer)
- Posting supervisor names on a safety scoreboard visible to all workers
- Issuing supervisors a copy of the updated site safety plan each quarter
Correct answer: Including measurable safety performance metrics in supervisor performance reviews and compensation
Tying safety metrics to performance reviews and compensation creates formal accountability and aligns supervisor incentives with safety outcomes.
