Isolate power supply to luminous discharge tube signs

Fire and rescue services should

• Refer to the responsibilities of fire and rescue services (this SA will be replaced when this piece of guidance is next reviewed)

Incident commanders should

• Isolate the sign using the fire switch if available and accessible
• Always assume there is a high voltage (3kV)
• Request attendance of the electricity supplier or competent person where isolation is not possible
• Ensure that care is taken if any signs need to be removed, and if so consider the use of RPE
• In the event of a tube failing, implement hazardous materials procedures; refer to Hazardous materials
