FREE Certified Arborist Safe Work Practices Questions and Answers

Question 1

How far away from a tree that is being felled should an uninvolved worker stand?

Accepted Answer

Two tree lengths minimum

Answer

Safety regulations for tree felling mandate a significant safety zone to protect workers from falling trees or debris. The minimum safe distance for uninvolved workers is typically at least two tree lengths away from the tree being felled. This provides ample space to avoid injury if the tree falls unexpectedly or if branches kick back.

Question 2

While hoisting a heavy object, where should the arborist stand?

Accepted Answer

As near to the object as possible

Answer

When hoisting a heavy object, the arborist should stand as near to the object as possible, but out of the direct line of fire if it were to swing or drop. This proximity allows for better control, observation of the load, and clear communication with other crew members. Standing too far away reduces control and visibility, increasing risk.

Question 3

What does it mean when a tree is referred to as a "barber chair"?

Accepted Answer

A tree splits from the back cut upward.

Answer

A 'barber chair' is a dangerous felling hazard where a tree splits vertically up the trunk from the back cut, often due to excessive lean or internal stresses, before the hinge wood can properly guide the fall. This causes the butt end of the tree to kick back violently and unpredictably. It poses an extreme risk to the feller and is a critical safety concern in arboriculture.

Question 4

If a chainsaw operator loses control of the tree while felling it, which way should he go?

Accepted Answer

45 degrees in the opposite direction of the intended fall to either side of a line

Answer

When felling a tree, the safest escape route is 45 degrees away from the intended fall direction, to either side of the line. This path moves the operator away from the butt of the tree, which can kick back, and also provides a clear line of sight to the falling tree. It minimizes the risk of being struck by the trunk or large branches.

Question 5

What is the term used for the upper part of the guide bar tip on a chainsaw?

Accepted Answer

The kickback quadrant

Answer

The kickback quadrant is the specific area on the upper part of the chainsaw guide bar tip where rotational kickback is most likely to occur. Contacting an object with this part of the chain can cause the saw to violently thrust backward and upward towards the operator. Understanding and avoiding contact with this quadrant is crucial for chainsaw safety.
