CTSP CTSP Struck-By and Falling Object Hazards 5

Question 1

A climber notices a large dead branch (widow maker) above their planned work area. What is the CORRECT first action?

Accepted Answer

Remove the hazard branch before proceeding with the primary work

Answer

Widow makers must be addressed before work proceeds in that area because they can fall unpredictably and no PPE fully mitigates the risk.

Question 2

Which condition makes a wood chunk ejected from a chipper MOST dangerous as a struck-by projectile?

Accepted Answer

High drum speed combined with hard, dry wood and a jammed infeed

Answer

High drum speed, hard dry wood, and a jammed infeed can cause explosive ejection of material at dangerous velocities.

Question 3

When using a friction saver to lower a large section of trunk, what is the MOST important factor in preventing an uncontrolled fall that could strike workers?

Accepted Answer

Ensuring the ground crew maintains a safe position off to the side while tending the lowering line

Answer

Ground crew positioning to the side of the load's path prevents struck-by injury if the rigging system fails or the load swings unexpectedly.

Question 4

A tree worker is injured when a section of wood rolls off a brush pile and strikes their foot. Which hazard category does this incident fall under?

Accepted Answer

Struck-by from rolling or sliding objects

Answer

Rolling or sliding objects that contact a worker are classified as struck-by hazards, even if the objects are not falling from height.

Question 5

What is the MOST effective engineering control to prevent struck-by injuries from falling branches during aerial lift operations?

Accepted Answer

Positioning the aerial lift so the basket is offset from the work area and using rigging to direct falling material away from personnel below

Answer

Engineering controls that direct falling material away from personnel are more effective than PPE at preventing struck-by injuries.
