CHST CHST - Construction Health and Safety Technician Incident Investigation and Reporting Questions and Answers 5 — Questions and Answers
Question 1: The 'Management Oversight and Risk Tree' (MORT) incident investigation method is primarily designed to identify:
- Which OSHA regulation was violated
- Management system deficiencies and oversight failures that allowed the incident (Correct answer)
- The exact physical cause of equipment failure
- Financial losses associated with the incident
Correct answer: Management system deficiencies and oversight failures that allowed the incident
MORT is a structured analytical tool that uncovers management system failures, inadequate controls, and oversight gaps that allowed hazards to produce an incident.
Question 2: What is the primary purpose of an incident investigation corrective action plan?
- To assign blame and discipline the responsible employee
- To document the incident for OSHA compliance only
- To prevent recurrence by eliminating root causes through systematic controls (Correct answer)
- To reduce workers' compensation premiums immediately
Correct answer: To prevent recurrence by eliminating root causes through systematic controls
The corrective action plan's primary purpose is preventing recurrence by implementing controls that address identified root and contributing causes.
Question 3: Under OSHA's anti-retaliation provisions (29 CFR 1904.35), an employer's post-incident drug-testing policy is permissible ONLY if:
- All employees are tested regardless of whether they reported an injury
- The testing is limited to situations where drug use could have caused the incident (Correct answer)
- The test is conducted within 8 hours of the incident
- Written consent from the employee is obtained first
Correct answer: The testing is limited to situations where drug use could have caused the incident
OSHA allows post-incident drug testing only when there is a reasonable possibility that drug use could have contributed to the incident, to avoid discouraging injury reporting.
Question 4: An OSHA 300 Log must be retained by the employer for a minimum of:
- 3 years
- 5 years (Correct answer)
- 7 years
- 10 years
Correct answer: 5 years
Under 29 CFR 1904.33, employers must save the OSHA 300 Log, 300-A summary, and 301 forms for 5 years following the end of the calendar year they cover.
Question 5: Which of the following BEST describes the difference between an incident and an accident in safety management?
- They are interchangeable terms with no meaningful distinction
- An incident is any unplanned event that could have or did cause harm; an accident implies randomness and is considered outdated (Correct answer)
- An accident is more severe than an incident
- An incident requires OSHA reporting while an accident does not
Correct answer: An incident is any unplanned event that could have or did cause harm; an accident implies randomness and is considered outdated
Modern safety management uses 'incident' to emphasize that unplanned events have identifiable causes, replacing 'accident' which incorrectly implies random, unpreventable events.
Question 6: A barrier analysis used in incident investigation focuses on:
- Physical fences and guardrails that failed during the incident
- Controls that should have prevented energy or hazard transfer to the worker and why they failed (Correct answer)
- Communication barriers between workers and supervisors
- Language barriers that contributed to misunderstanding of safety instructions
Correct answer: Controls that should have prevented energy or hazard transfer to the worker and why they failed
Barrier analysis examines the energy source, the target (worker), and the controls (barriers) that should have interrupted the hazardous energy transfer, assessing why each barrier failed.
Question 7: Which information is required on the OSHA 300-A Annual Summary that is NOT required on the OSHA 300 Log?
- Number of days away from work
- Description of the injury or illness
- Average number of employees and total hours worked (Correct answer)
- Body part affected by the injury
Correct answer: Average number of employees and total hours worked
The 300-A Annual Summary requires the average number of employees and total hours worked during the year to allow calculation of injury and illness rates, data not captured on the 300 Log itself.
