Now you need to assess risks and apply controls for some of the hazards in the scenario.
First, assess the risk of engulfment in a ground collapse for personnel working in trenches greater than 1.5 metres. Because situations can vary and judgement is subjective, select the two most appropriate answers.
]]>
Almost certain (5)]]>
Likely (4)]]>
Possible (3)]]>
Unlikely (2)]]>
Rare (1)]]>
Correct.]]>
Incorrect.]]>

Not quite. ‘Possible’ is a realistic assessment based on current knowledge about trench collapses in the industry and worldwide. ‘Likely’ is also realistic, depending on the nature of the ground conditions, depth of trench and other factors.]]>
That’s right. ‘Possible’ is a realistic assessment based on current knowledge about trench collapses in the industry and worldwide. ‘Likely’ is also realistic, depending on the nature of the ground conditions, depth of trench and other factors.]]>
