About

Safety Observer 3.0

Features
Read full description

Safety Observer is a tool for measuring and improving workplace safety behaviour and safety conditions. It can be used in a wide variety of sectors and settings. It shows the workplaces' current level of safety expressed as the percentage of correct safety observations, which can be supported by notes, photos and smileys. Immediate results are provided on-screen and sent as a PDF report to your e-mail address. Results can directly be compared with results from previous measurements from the same or other workplaces. In the web-based 'administrator' module for the app you can customize your company's own observation lists and administer results (PDF reports and Excel statistics). The lists can be accessed by your company's 'users' for performing safety observations at various work sites.
