No matter which outdoor task you’re working on, it’s important to follow best safety practices when using ladders. According to the U.S. Consumer Product Safety Commission, more than 500,000 people are treated for ladder-related injuries each year. Falling from any height could result in broken bones, head injuries, or skin lesions, and DIYers need to be especially careful. Hanging outdoor lights or cleaning the gutters tend to be solitary jobs, meaning no one is there to help you or break your fall in the case of a ladder accident. No matter the reason you’re up on a ladder, here are the safety precautions you need to take.

1. Inspect the ladder before use.

Before you set up a ladder, check it over carefully. Make sure the rungs are secure and free of dirt and buildup. Read the manufacturer’s instructions for any specific safety or usage tips.

2. Position the ladder in a sturdy spot.

With an extension or straight ladder, make sure that the tops of both rails make solid contact with the wall and that both legs are placed firmly on even ground. Set the base of the ladder 1 foot from the wall for every 3 feet of ladder height. For example, if you’re using a 24-foot ladder, position the base 8 feet away from the wall. If you’re working on soft ground, add a piece of plywood under the ladder’s legs to ensure solid footing.

3. Stay safe while on the ladder.

While on the ladder, keep your hips between the rails for good balance. Always wear rubber-soled or nonslip shoes on a ladder, and avoid working in rainy, snowy, or windy weather. You should never climb a ladder that’s wet. If you are getting something off a shelf, have someone there to spot you and grab the item from you before climbing down.
