WTT Tower Climbing & Rescue Safety 3

Question 1

What is the maximum wind speed at which most manufacturers permit turbine tower climbing operations?

Accepted Answer

20 mph (32 km/h)

Answer

Most OEM guidelines and industry standards set a 20 mph (32 km/h) wind speed limit for safe ladder climbing on turbine towers.

Question 2

A technician must perform a pick-off rescue of an unconscious co-worker suspended in a harness 60 meters above ground. The FIRST step is to:

Accepted Answer

Contact emergency services and establish incident command

Answer

Activating emergency services and establishing incident command ensures resources are en route while preventing rescuers from self-endangering without a plan.

Question 3

Which condition describes 'suspension trauma' (orthostatic shock) in a harness-suspended victim?

Accepted Answer

Blood pooling in the legs leading to cardiovascular collapse

Answer

Suspension trauma occurs when blood pools in immobilized lower limbs, reducing venous return and potentially causing unconsciousness or cardiac arrest.

Question 4

What is the recommended recovery position for a victim retrieved after prolonged harness suspension?

Accepted Answer

Semi-recumbent (sitting at 45°) for 30 minutes before lying flat

Answer

Gradually transitioning from seated to supine prevents a sudden rush of pooled blood returning to the heart, which could cause cardiac arrest.

Question 5

What type of fall arrest anchor is required for each climber on a wind turbine ladder equipped with a self-retracting lifeline (SRL)?

Accepted Answer

A dedicated anchor rated at 5,000 lbs per attached person

Answer

ANSI Z359 requires a dedicated fall arrest anchor rated to a minimum 5,000 lbs (22 kN) per attached person.
