Regardless of the Ladder you're using, be sure to check the load rating. The load rating needs to cover your weight AND the weight of your tools. You should also consider the material that your Ladder is made of and whether it's appropriate for your intended use. Aluminum and steel ladders conduct heat and electricity and should never be used for electrical work. Fiberglass and wood ladders are suitable for electrical work, but wood ladders are especially vulnerable to damage and decay. No matter what type of Ladder you're using, you should always inspect it, check for cracks, and ensure the frame, rungs, and feet are not compromised.
