Pre-start and safety app
Hypothetical. Not a client, not a result.
// The problem
An open-pit mine does equipment pre-starts and hazard reports on paper, so defects found by one shift are missed by the next and supervisors cannot see the state of the fleet.
// What we would build
An iOS and Android app for operators and supervisors with pre-start checklists per machine, hazard reports with photos and take-5 assessments, working offline in the pit or underground, with a web view for maintenance and safety teams.
// What is in it
- Equipment, spares and consumables tracked across sites with on-metal RFID tags and QR labels
- Pre-start checklists per machine type, with critical defects flagging the machine out of service
- Defects sent to maintenance with photos and the machine's hours
- Hazard reports and take-5 assessments in English and French
- Works offline and syncs on the site network
- Fleet status board for supervisors at shift change
- Records kept to the retention rules your safety team names
