Which type of stepladder is forbidden while working on electrical equipment?

• A. Wooden
• B. Fiberglass
• C. Aluminum
• D. Plastic

Answer: (C)

When working on electrical equipment, the use of aluminum stepladders is forbidden due to aluminum's property as a good conductor of electricity. If an aluminum ladder comes into contact with live electrical wires, it can easily conduct electric current, posing a significant risk of electric shock or electrocution to the individual using the ladder. In contrast, wooden stepladders are non-conductive, making them a safer option in environments where electrical equipment is present. Fiberglass ladders are also non-conductive and are specifically designed for use around electricity, which is why they are frequently recommended in electrical work. Plastic ladders, while generally non-conductive, may not have the same strength and durability characteristics as fiberglass or wood, but they still do not pose the same electrical hazards as aluminum.
