Rigger Safety – VO1BT Procedure Changes Due To New Weather Radar

A new, more powerful, weather radar has been built to replace an existing one at Holyrood.

RF Hazard signs have been placed on the two towers at VO1BT. The rf radiation levels are safe at ground level but can exceed acceptable limits while climbing.

Before climbing the tower contact the number on the sign so that the weather radar may be made safe. Advance notice is required and a Call Before You Climb procedure must be followed as laid out on the left side of the following document: 20181206 – CBYC Procedure V1.0

The RF energy at ground level is safe. The exposure risk is only when entering the path of the radar antenna beam. The hazard begins at 304 MSL.
