Question 1
1. What is the difference between linear and non-linear accident models? Why are nonlinear accident models not used more often in workplace accident investigations?
Your response must be at least 75 words in length. Question 2
1. Why is it better to apply the multiple causation theory rather than the unsafe acts/unsafe
conditions model to an accident investigation? Provide an example that illustrates your
point.
Your response must be at least 75 words in length. Question 3
1. Consider the following accident scenario:
A maintenance worker mopped the floor in a hallway and then left the area without
posting a "wet floor" warning. The lighting in the hallway had been lowered to conserve
energy, so visibility was poor. Two employees walked down the hallway on their way to
lunch, discussing where they wanted to go to eat. One of the employees slipped and fell,
suffering a broken wrist.
Discuss how you could apply a domino theory to investigate this accident. You may make
additional assumptions about the scenario, as needed, for your discussion.
Your response must be at least 200 words in length. Question 4
1. Consider the following accident scenario:
Two workers were assigned to replace a water valve located in an underground concrete
vault. After removing the manhole cover, worker #1 climbed down the ladder into the
vault. Worker #1 collapsed and became unconscious within seconds of reaching the
bottom. Worker #2 went down the ladder to rescue worker #1 but was quickly overcome
by the lack of oxygen. Both workers died at the bottom of the vault.
Discuss how you could apply the Haddon matrix theory to investigate this accident. You
may make additional assumptions about the scenario, as needed, for your discussion. Your response must be at least 200 words in length.
