Prioritize Ladder and Personal Insulation Safety

What happens here

The master electrician begins by immediately emphasizing the critical importance of using a fiberglass ladder for any electrical work involving live service wires. He clarifies that an aluminum ladder would be extremely dangerous, especially when working against conductive surfaces like aluminum siding, as it could create a direct path for electrical current through the worker's body. He also implicitly highlights the importance of wearing proper work shoes which offer an additional layer of insulation.

Goal: Establish a safe working environment with proper insulation.
