Low voltage does not mean low available current. A storage battery can deliver enormous current into a short circuit.
High charge or discharge rates can create damaging heat and may cause gases to be released, depending on battery chemistry and condition.
Large capacitors can retain dangerous voltage after AC power is removed, so “off” does not necessarily mean electrically safe.
Meters, probes, insulation, and category ratings all matter when working around hazardous voltage.
Tower work combines fall, mechanical, and electrical hazards. A qualified helper or observer is an essential part of safe work practices.
Plan for the antenna or support to fall in the worst plausible direction. Clearance must protect against accidental contact, not just normal upright spacing.
