How It Works
Your safe reach is your height plus about 12 inches (arm raised). Never stand on the top 2 steps of a step ladder. Extension ladders should be set at a 75-degree angle (base 1 ft out for every 4 ft of height). For exterior painting, rent scaffolding for areas wider than 4 feet — it is safer and faster than repeated ladder moves.
