The National Institute for Occupational Safety and Health (NIOSH) announced June 17 that it has released a new ladder safety smartphone app, which uses visual and audio signals to make it easier for workers using extension ladders to check the angle of the ladder and offers useful tips for using extension ladders safely. The app is available for free download on iPhone and Android devices. 

Falls from ladders are a common source of preventable construction injuries and misjudging the ladder angle is a significant risk factor for a fall, according to NIOSH. 

In addition to providing feedback on how to position an extension ladder at the optimal angle, the app also provides references and a safety guide for extension ladder selection, inspection, accessorizing, and use.
