Ladder Safety Using Power Washers Dealing With Lead Paint Personal Protective Equipment   Ladder Safety Here are some useful tips about ladders that apply to both interior and exterior use: Inspect ladders before use. Make sure that the rungs are intact and free of dirt and paint buildup that could interfere with footing. When extending or retracting an extension ladder, hold the pulley rope firmly; if the rope is released, the upper section could drop on your fingers, arms or feet. Follow the "four contact" rule: When using an extension ladder, make sure that the tops of both rails make solid contact with walls, and that both legs make solid contact with the floor or ground. Never stand higher than the third-highest rung on a ladder. Make sure that the ladder reaches at least three feet higher than the highest level you need to stand. Place foam protectors or wads of cloth on the tops of extension ladders, to prevent them from sliding and to protect the walls. On a stepladder, make sure the spreader bar is fully extended and locked in place. With a straight or extension ladder, make sure that the base is 300mm away from the wall for every 1 metre of height. Make sure your pockets are empty of knives, scissors or other pointed tools before climbing any ladder. When on the ladder, keep your hips between the rails for good balance. Do not push or pull too hard on a scraper or other tool while balanced on the ladder. Always wear rubber-soled or another type of non-slip shoe on a ladder . Special Guidelines for Outdoor Ladder Use: Avoid working in wet or windy weather, and do not climb a wet ladder. Keep all ladders away from power lines -- especially metal ladders. Make sure that the ground under the ladder is secure -- place plywood under the legs to ensure solid footing. A ladder can be additionally secured by tying it to a sturdy portion of the house or to a large eyebolt in the wall or fascia board.
