Abstract: A system and method are disclosed for alerting safety personnel of unsafe air temperature conditions. The system includes a removable safety system operable to be coupled to safety personnel for detecting ambient temperature conditions is provided. The system further includes a control unit operable to be coupled to the safety personnel having electronics operable to communicate signals associated with the ambient air condition. The system further includes a sensor unit operable to be positioned with an ambient environment and coupled to a substantially centered position of a viewmask. The sensor unit includes a temperature sensor having an temperature dependent operating mode communicatively coupled to the control unit and a first indicator and second indicator operable to display an indication representing an ambient air temperature condition.
