Stihl Risk Management & Mitigation 2

Question 1

Before felling a tree near a power line, what is the FIRST risk mitigation step a Stihl-certified operator should take?

Accepted Answer

Contact the utility company to assess clearance or de-energize the line

Answer

Any tree work near power lines requires utility notification and clearance verification before cutting begins.

Question 2

What is the primary purpose of establishing an escape route at a 45-degree angle opposite the felling direction?

Accepted Answer

It provides the safest path away from the stump if the tree kicks back or the hinge fails

Answer

The 45-degree rear escape path moves the operator away from both the stump and the falling trunk's potential rebound zone.

Question 3

During a jobsite risk assessment, an operator identifies a dead limb hanging in the canopy of the tree to be felled. What is this hazard commonly called?

Accepted Answer

A widowmaker

Answer

Detached or dead overhead limbs that can fall unexpectedly are known as widowmakers and must be identified before cutting.

Question 4

Which control measure BEST mitigates the risk of kickback when operating a chainsaw?

Accepted Answer

Avoiding contact between the upper quadrant of the bar tip and any object

Answer

Kickback occurs when the bar nose's upper quadrant contacts an object, so keeping that zone clear is the primary control.

Question 5

Under the hierarchy of controls, personal protective equipment like chaps and helmets is considered what level of risk control?

Accepted Answer

The last line of defense after elimination, substitution, engineering, and administrative controls

Answer

PPE sits at the bottom of the hierarchy of controls because it protects the worker only after other measures fail.
