Example: In case of temperature monitoring in chemical factories, temperature of boilers nearing set threshold limits are alerted to customers as warning alerts that can be acted upon or ignored (acted upon refers to actions performed to sustain normal temperatures by either lower the boiler temperatures or checking on chemical proportions in boilers and so on).
Example: temperature monitoring in hazardous factories that store chemicals and chemical boilers require consistent and careful temperature monitoring. These critical alerts enable in time checks through critical alerts and prevents harmful events.
