STSC Safety Program Implementation 4 — Questions and Answers
Question 1: When conducting a Job Hazard Analysis (JHA) for a new construction task, what is the correct first step?
- Identify the hazards present in each step
- Break the job down into its basic steps (Correct answer)
- Determine appropriate controls for each hazard
- Assign PPE requirements to workers
Correct answer: Break the job down into its basic steps
A JHA begins by breaking the job into its basic sequential steps before hazards can be identified and controls selected.
Question 2: Which document formally establishes the authority and responsibility of the safety supervisor on a construction site?
- The site safety plan
- The written safety program (Correct answer)
- The OSHA 300 log
- The project schedule
Correct answer: The written safety program
The written safety program defines roles, authorities, and responsibilities including those of the safety supervisor.
Question 3: A supervisor notices workers are not following the lockout/tagout procedure. What is the MOST appropriate immediate action?
- File a report after the shift ends
- Stop the work and correct the procedure before resuming (Correct answer)
- Retrain workers during the next scheduled safety meeting
- Issue a written warning and allow work to continue
Correct answer: Stop the work and correct the procedure before resuming
Lockout/tagout violations present an immediate life-threatening hazard that requires stopping work until the procedure is followed correctly.
Question 4: Under OSHA's construction standards, how long must employers retain OSHA 300 logs?
- 1 year
- 3 years
- 5 years (Correct answer)
- 10 years
Correct answer: 5 years
OSHA requires employers to retain the OSHA 300 log, 300A summary, and 301 incident reports for five years following the end of the calendar year they cover.
Question 5: What is the primary purpose of a pre-task safety briefing (toolbox talk) on a construction site?
- To satisfy OSHA documentation requirements
- To communicate daily hazards and controls to workers before work begins (Correct answer)
- To update workers on company policy changes
- To review injury statistics from the previous week
Correct answer: To communicate daily hazards and controls to workers before work begins
Pre-task briefings communicate site-specific hazards and the controls in place so workers can work safely that day.
Question 6: Which hierarchy of controls method is considered MOST effective at reducing workplace hazards?
- Administrative controls
- Personal protective equipment
- Elimination of the hazard (Correct answer)
- Engineering controls
Correct answer: Elimination of the hazard
Elimination removes the hazard entirely and is ranked highest in the hierarchy of controls because it provides the most reliable protection.
Question 7: A new subcontractor arrives on site without a site-specific safety orientation. What should the supervisor do?
- Allow them to begin work since they likely have general safety training
- Provide orientation before permitting any work to begin (Correct answer)
- Assign them to low-risk tasks until orientation can be scheduled
- Notify the general contractor and let management decide
Correct answer: Provide orientation before permitting any work to begin
All workers must receive site-specific orientation before starting work to ensure they understand site hazards and emergency procedures.
