ASP ASP Emergency Response & Incident Investigation 2 — Questions and Answers
Question 1: Which investigation technique involves recreating the sequence of events leading to an incident on a timeline?
- Barrier analysis
- Events and causal factors analysis (Correct answer)
- Change analysis
- Management oversight and risk tree (MORT)
Correct answer: Events and causal factors analysis
Events and causal factors analysis maps the sequence of events and conditions on a chronological chart to identify contributing causes.
Question 2: What does the term 'near miss' refer to in safety management?
- An incident resulting in minor injuries only
- An unplanned event that did not result in injury or damage but had the potential to do so (Correct answer)
- An incident where the employer narrowly avoided an OSHA inspection
- A situation where PPE prevented a more severe injury
Correct answer: An unplanned event that did not result in injury or damage but had the potential to do so
A near miss is an unplanned event with the potential for harm that did not result in injury, illness, or property damage.
Question 3: In emergency response planning, what is the purpose of a 'shelter-in-place' procedure?
- To evacuate employees to a designated outdoor muster point
- To keep employees inside a building to protect them from an external hazard (Correct answer)
- To lock down a facility against unauthorized entry
- To isolate injured workers until EMS arrives
Correct answer: To keep employees inside a building to protect them from an external hazard
Shelter-in-place directs employees to remain inside a sealed area of the building to avoid exposure to external hazards such as chemical releases.
Question 4: Which factor is considered when calculating the severity rate (SR) in incident statistics?
- Number of recordable injuries per 200,000 hours worked
- Days away from work, job transfer, and restricted duty (Correct answer)
- Direct and indirect costs of all incidents
- Number of near misses reported per quarter
Correct answer: Days away from work, job transfer, and restricted duty
The severity rate uses lost workdays, restricted duty days, and job transfer days to reflect the seriousness of work-related injuries.
Question 5: What is the 'swiss cheese model' used to explain in safety science?
- How redundant safety barriers can each have gaps that align to allow an accident to occur (Correct answer)
- Why cheese production facilities have a higher injury rate than other food processors
- How overlapping regulations create confusion for safety professionals
- The layered approach to personal protective equipment selection
Correct answer: How redundant safety barriers can each have gaps that align to allow an accident to occur
The Swiss cheese model, developed by James Reason, illustrates how accidents occur when holes in successive defensive layers align to create an unobstructed path to failure.
Question 6: Which document outlines the specific roles, responsibilities, and actions required during an emergency at a facility?
- Safety Data Sheet (SDS)
- Emergency Response Plan (ERP) (Correct answer)
- Job Safety Analysis (JSA)
- Hazard Communication Program
Correct answer: Emergency Response Plan (ERP)
An Emergency Response Plan defines roles, responsibilities, communication procedures, and actions employees must take during various emergencies.
