This video shows you how to safely use an extension ladder. To put the ladder up put the bottom against the wall and walk it hand by hand until the top is against the ladder. Then grab the bottom and pull it out. To make sure the ladder is at the correct angle and stand with your toes against the base of the ladder and stretch your arms out straight. You should be able to grasp a rod. If you can't reach it you should readjust it. Avoid over reaching to the sides.
