CHST - Construction Health and Safety Technician Incident Investigation and Reporting Questions and Answers Flashcards

The 'Management Oversight and Risk Tree' (MORT) incident investigation method is primarily designed to identify:

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.

What is the primary purpose of an incident investigation corrective action plan?

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.

Under OSHA's anti-retaliation provisions (29 CFR 1904.35), an employer's post-incident drug-testing policy is permissible ONLY if:

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.

An OSHA 300 Log must be retained by the employer for a minimum of:

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.

Which of the following BEST describes the difference between an incident and an accident in safety management?

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An incident is any unplanned event that could have or did cause harm; an accident implies randomness and is considered outdated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.

A barrier analysis used in incident investigation focuses on:

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.

Which information is required on the OSHA 300-A Annual Summary that is NOT required on the OSHA 300 Log?

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.
