Risk Scenarios are active safety barriers used in monitoring through the Dersalis platform. They analyze real-time data collected from workers and trigger alerts when physiological or behavioral conditions fall outside the expected range. These alerts help anticipate operational risks and require corrective actions to protect workers' health and safety.
Below, we explain how to correctly configure risk scenarios, what information to consider in the planning phase, and show practical examples of configuration.
1. What are Risk Scenarios?
A risk scenario allows the platform to monitor and evaluate undesired health conditions. It uses triggers based on variables like heart rate, movement, temperature, and others to identify irregular patterns. When one of these conditions is detected, the system automatically generates alerts that guide mitigation actions.
2. Initial Planning
Before creating a scenario, it’s essential to understand the operation’s context and the associated risks. We recommend answering the questions below together with your occupational health team:
1) What operation will be monitored?
Describe the activity and how it’s carried out.
Example: “Monitoring of crane operators working in the Cold Rolling Mill.”
2) What is being detected?
Specify the undesired biological condition.
Example: “Initial signs of relaxation based on a sustained drop in heart rate, which may lead to drowsiness and/or loss of focus.”
3) What are the risks involved?
Explain the possible impacts of the condition.
Example: “Moderate risk of inattention that may affect work procedures and cause sleep episodes.”
4) What kind of action can be taken?
List appropriate responses to the condition.
Example: “Early intervention with a short break, walking, coffee, or even stopping the activity.”
3. Common Scenario Examples
Below are three typical configurations. The illustrations show how alerts behave over time and escalate in severity.
Exposure to High Temperatures
This scenario tracks heat exposure above 35 °C. If it lasts more than 10 minutes, an alert is triggered. If the temperature remains high, alerts escalate (levels 1 to 5). At level 5, corrective actions are mandatory.
Fatigue Monitoring
Based on increased parasympathetic activity. If it lasts more than 5 minutes, an alert of intensity 3 is triggered. Every 2 minutes, the severity increases and corrective action is required.
Low Movement Detection
If the worker remains still for 10 minutes, an alert of intensity 1 is generated. Every 5 minutes without movement, the severity increases, requiring action starting at level 4.
4. Implementation Tip
Involve field teams in the design of corrective actions. This ensures practical solutions and avoids resistance during daily use.
