Question 2

During a tower rescue, what is the first action the rescue team should take upon reaching the injured worker?

Accepted Answer

Assess the worker's condition and secure them to prevent further fall

Answer

Assessment and securing the worker prevents additional injuries and determines the appropriate rescue technique.

Question 3

What is suspension trauma and why is it a critical concern during tower rescue?

Accepted Answer

It is a life-threatening condition caused by prolonged motionless suspension in a harness that restricts blood flow

Before each use by the worker and annually by a competent person

Pre-use inspection by the worker catches daily wear and damage, while annual competent person inspection provides thorough examination.

Question 5

What is the purpose of a rescue pre-plan at a tower work site?

Accepted Answer

To establish step-by-step procedures for rescuing a worker before an emergency occurs

Answer

A rescue pre-plan ensures all crew members know their roles, equipment locations, and procedures before an emergency.
