Check a Card only option

Posted in Communications

Since updating the Sentinel app this week, we have recognised that there are two groups of users:

  1. Controllers of Site Safety (COSS) who would like a simplified version of the app – i.e. perform the same process as before by scanning a worker’s Sentinel card to retrieve competency, sponsor, and medical details, etc.
  2. Controllers of Site Safety (COSS) who would like to use the new functionality on the app and learn as they go – i.e. recording safety briefs, logging competence usage and swiping out at the end of each shift, etc.

There is no right or wrong here.

For users in group 1 we offer a simple solution; they can still Check a Card until they have received a local briefing or read the wide range of learning materials.

For users in group 2 we offer a range of learning materials, including e-Learning, if they would like to get the most out of the upgraded app.
