Context-aware wearable safety system

In an example embodiment, biometric data and environmental data are obtained from sensors. Corporate information system (CIS) information is retrieved for a worker, with the CIS information including a schedule of tasks assigned to the worker. A task currently being performed by the worker is determined based on the schedule of tasks. Weights are assigned to the biometric data and the environmental data. The weights vary between data from different sensors, with the weights assigned based on the task currently being performed by the worker. A current safety score is assigned for the worker based on the calculation of a formula, with the formula using the assigned weights as coefficients to variables, with the variables being values obtained from the biometric data and the environmental data. The current safety score is compared to a safety threshold, and if the threshold is violated, an alert is generated to the worker.
