Mobile Inspection App

The mobile inspection app allows users to build custom checklists for walk-around inspections, hazard assessments, toolbox talks, confined space entry permits, hot work permits, equipment checklists, preventative maintenance checklists, pre-tow inspections, and more.

The app works in offline mode when internet service is not available. Users can document findings with pictures and notes with the Inspection app, capture inspectors' signatures, and toolbox talk attendees with the date and time stamp. Email notifications are provided upon completion of an inspection that includes a list of failed questions.

Failed audit findings can either be marked as resolved or elevated to an observed hazard or near miss for root cause analysis and correction action assignment.
