Question 1

What is the purpose of a Job Hazard Analysis (JHA), also called a Job Safety Analysis (JSA)?

Accepted Answer

To identify hazards associated with each step of a job task and determine controls

Answer

A JHA breaks a job into sequential steps, identifies hazards at each step, and prescribes controls to eliminate or reduce those hazards before work begins.

Question 2

In root cause analysis, what does the '5 Whys' technique involve?

Accepted Answer

Repeatedly asking 'why' to drill down from symptoms to the underlying root cause of a problem

Answer

The 5 Whys technique iteratively asks 'why' at each answer until the fundamental root cause is reached, typically within five iterations.

Question 3

What is the OSHA recordkeeping criterion for a 'Days Away from Work' (DAFW) case?

Accepted Answer

A work-related injury or illness where the physician recommends at least one day away from work

Answer

A DAFW case is recorded when a physician or other licensed health care professional recommends that the worker remain away from work for at least one calendar day due to a work-related condition.

Question 4

What does the 'Swiss Cheese Model' of accident causation illustrate?

Accepted Answer

Multiple defensive layers each have holes; accidents occur when the holes align

Answer

Reason's Swiss Cheese Model shows that accidents require multiple defense layers to fail simultaneously — when the 'holes' in each layer align, a hazard passes through causing an incident.

Question 5

Which safety metric is calculated as (number of recordable incidents × 200,000) ÷ total hours worked?

Accepted Answer

Total Recordable Incident Rate (TRIR)

Answer

TRIR uses 200,000 hours (equivalent to 100 full-time workers working one year) as a normalizing factor to allow comparison across organizations of different sizes.
