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

Climbing a tower without a helper or observer is never considered safe due to a number of critical safety concerns. Working at heights poses inherent risks, including the potential for falls, equipment failure, or sudden health emergencies. Having a second person present ensures that assistance can be provided in case of an accident, as well as facilitating communication regarding hazards or conditions that may arise while working on the tower. Safety protocols emphasize the importance of being monitored or supported to mitigate these risks, particularly in environments where isolation could lead to severe consequences. Therefore, the correct approach is to always have a helper or observer present during such activities.
