Scaffold Safety

Use - Insulated Lines

There is a minimum clearance requirement between scaffolds and power lines. Scaffold systems and all components should remain clear of power lines during all stages of use. Use the following charts for specific clearance info:

Voltage Minimum Distance Alternatives
Less than 300 volts 3 feet (0.9m) None
300 volts to 50 kv 10 feet (3.1m) None
More than 50 kv 10 feet (3.1m) plus 0.4 inches (1.0 cm) for each 1 kv over 50 kv 2 times the length of the line insulator, but never less than 10 feet (3.1m)
