NIOSH recently released free ladder safety applications for Android and Apple phones. They allow the phone to be held against a ladder and used as an inclinometer; the angle displays on the screen. When the ladder is set to the proper angle of 75.5 degrees the phone vibrates and the indicator turns green. The indicator will be red if the angle of the ladder is too steep or shallow. The app also includes a series of tips on setting up and using extension ladders as well as an interactive tool for selecting the correct type and grade of ladder for the job. Links to the free apps can be found on the NIOSH website.
