The app provides feedback to the user on positioning the extension ladder at the optimal angle. It also provides references and a safety guide for extension ladder selection, inspection, accessories and use.
Falls from ladders are a common source of preventable construction injuries, and incorrect ladder angle is a contributing factor. A ladder set too steep is more likely to fall back or away during use, and a ladder set too shallow can slide out. Either way, the worker is in danger.
“The ladder safety app is an innovative way to help keep workers safe ...,” says NIOSH. It was developed with input from the ANSI A14 committee on Ladder Safety, the American Ladder Institute and other stakeholders.
