Stihl Risk Management & Mitigation 3

Question 1

An operator notices the chain brake on a Stihl chainsaw fails to engage during the pre-use inspection. What is the correct risk mitigation action?

Accepted Answer

Tag the saw out of service and repair it before any use

Answer

A non-functioning chain brake removes a critical safety device, so the saw must be taken out of service until repaired.

Question 2

Which weather condition should MOST likely trigger a stop-work decision during felling operations?

Accepted Answer

Sustained high winds that can alter the tree's fall direction

Answer

High winds can push a falling tree off its intended lay and dislodge overhead limbs, making felling unpredictable.

Question 3

What hazard does a spring pole present, and how is the risk best mitigated?

Accepted Answer

Stored energy that can release violently; relieve tension with small shaving cuts on the inside of the bend

Answer

A bent sapling or limb under tension stores energy that can whip loose, so tension is released gradually with shallow cuts on the compression side.

Question 4

Why should a chainsaw operator always plan a retreat before beginning the back cut rather than after?

Accepted Answer

Once the tree begins to fall there is no time to clear obstacles or choose a path

Answer

The tree can commit to falling within seconds of the back cut, leaving no time to improvise an escape.

Question 5

A certified operator is asked to fell a heavily leaning tree that exceeds their training level. What is the appropriate risk-based response?

Accepted Answer

Decline the cut and escalate to a qualified specialist or supervisor

Answer

Working beyond one's training level is an unacceptable risk, and hazardous trees like heavy leaners require appropriately qualified personnel.
