The National Institute for Occupational Safety and Health (NIOSH) is dedicated to ensure the safety of extension-ladder users by developing and disseminating an easy-to-use interactive ladder safety application for smart phones. The NIOSH Ladder Safety application features a multimodal indicator, which uses visual and sound signals to assist the user in positioning an extension ladder at an optimal angle. Furthermore, the application provides graphic-oriented interactive reference materials, safety guidelines and checklists for extension ladder selection, inspection, accessorizing, and use. The application is intended to help a wide range of ladder users, employers, and safety professionals, with their ladder-related safety needs. The ladder safety app is also 508 compliant.

Greatest App of all Time??

This app literally saved my life and allowed me to safely catch my wife having an affair with my neighbor Steven. Had i not used this app i would’ve fallen over in shock when i looked into my bedroom window.

Measure tool of this App is no longer working

Recently downloaded this app again, the most recent update seems to have rendered the measuring angle aspect of this app inoperable.

Please fix this when you get a moment!
