Background
A major mining operation in South America has integrated Readi to manage fatigue risks across multiple operational areas, including people transportation, mining operations (MineOps), and dangerous materials unit. The operation employs over 350 operators, including both internal staff and contractors, working in a challenging shift environment with 7-day rotating shifts between day and night work.
Operators from the dangerous materials unit, night shift MineOps personnel, and those involved in internal and long-range transportation also use additional anti-fatigue cameras while working to supplement the mine operation's fatigue management system.
Fatigue management is overseen by a dedicated Health, Safety, and Environment (HSE) team, which includes four personnel responsible for Readi, as well as a fatigue committee led by the HSE superintendent. The company’s HSE protocols ensure comprehensive fatigue management by incorporating Readi’s data into both pre-shift readiness assessments and ongoing operator supervision.
Operators wear ReadiWatches for sleep data collection to ensure compliance with the company’s fatigue management policy. In this mining site, operators must achieve at least 6 hours of sleep before a shift to be cleared for work. In cases where the operator falls below the required sleep, they are temporarily stood down and given time to rest. They must sleep the number of missing hours until reaching 6 hours total of sleep before they are cleared for work.
Supervisors also review each operator's individual fatigue score (ReadiScore) one hour before each shift starts. This fatigue score is based on their last three days of sleep. Operators must maintain a score of over 70 during their shifts to be able to work.
When a worker is rejected for work due to fatigue risk, supervisors take screenshots of the operators' fatigue risks and the countermeasures taken. They then share them with the fatigue committee via a dedicated WhatsApp group for rapid response and documentation.
This mining operation uses ReadiSupervise to monitor and track operator fatigue metrics in real time.
With the integration of Readi, fatigue risk is now a visible and proactive part of the daily safety processes. This has allowed the mining operation to mitigate risks early and prevent potential fatigue-related incidents from occurring.
