How it works
The app provides user-friendly guidance and interactive tools to prevent major causes of falls.
- Uses visual, sound, and vibration signals to make it easier for users to set an extension ladder at the proper angle and to check the verticality of extension and step ladders.
- The proper angle is about 75 degrees.
- Provides a procedure to select the minimum required ladder duty rating corresponding to user characteristics and task.
- Includes a comprehensive checklist for ladder inspection and setup
- Presents a set of rules for safe ladder use in a user-friendly format.
- Describes a number of available extension ladder safety accessories.
Using smart phone technology, the app delivers ladder safety tools, information, reference materials, and training resources to individual ladder users. The app is available in English and Spanish as a free download for Apple iPhone/iPad and Google Android devices.
Reviews
As of December 2023, the app has been downloaded more than 850,000 times. Users have provided high ratings of the app, which has also been promoted by state officials, industry leaders, and safety professionals. Many companies have incorporated the use of the app as part of their safety policy. It has also received considerable international attention.
NIOSH researchers consider feedback from ladder users to further improve the app’s appearance, content, and function. As part of this effort, the latest app update includes interactive tools and guides on step ladder safety.
