Question T0B03
From subelement T0 - T0B
Under what circumstances is it safe to climb a tower without a helper or observer?
Why is this correct?
The correct answer is D (Never) because tower climbing always requires a helper or observer for safety. The retrieved context explicitly states this fundamental rule: your ground crew serves as your safety net, can call for help in emergencies, guide you through difficult maneuvers, and monitor changing conditions like weather. None of the other options matter—whether doing electrical work, mechanical work, or working at low heights—a helper is always mandatory for safe tower climbing practices.
Memory tip
When you see 'never' or 'always' in safety questions, these absolute terms usually indicate the correct answer in amateur radio. Safety rules don't have exceptions based on work type or height—they're designed to prevent the worst-case scenario that could happen during any tower climb.

Professional tower climbers and antenna installers follow strict OSHA regulations that mandate spotters for all tower work, regardless of height or task complexity. Your ground crew provides emergency response capability, weather monitoring, tool assistance, and verbal guidance during complex maneuvers. In amateur radio station safety practices, this principle extends beyond towers to any elevated antenna work—even simple tasks can become dangerous without proper support and observation from ground level.
Think about it
Why do you think professional tower climbers are required to have spotters even for routine maintenance tasks they've performed hundreds of times before?
