Under what circumstances is it safe to climb a tower without a helper or observer?

1. When the weather is clear

2. Never

3. When you are experienced

4. Only during ground inspections

The correct answer is: Never

It is never safe to climb a tower without a helper or observer because having a companion is crucial for safety during any climbing operation. Climbing can be inherently dangerous due to factors such as falls, equipment failure, or sudden health issues. An observer or helper is essential for calling for help in case of an emergency, ensuring that first aid can be rendered quickly if needed, and providing guidance and support. Climbing without assistance increases the risk exponentially, as there would be no one to assist in case of any mishap, making it vital to have a second person present. This emphasis on safety is supported by industry standards and best practices which prioritize having an observer or helper during such activities to mitigate risks.
