Abstract: A system and method for thermal event detection in a transport refrigeration unit that includes a safety controller (302) communicatively coupled to a linear heat detector (304) affixed to a hood (202) of the transport refrigeration unit. The safety controller is configured to detect a change in resistance of the linear heat detector and initiate an action like shutting off the fuel supply to an internal combustion engine inside the compartment. The linear heat detector is operative to create, subsequent to being exposed to a temperature greater than or equal to a threshold temperature in the interior compartment (208), a change in resistance along at least a portion of the linear heat detector. The safety controller is further configured to initiate an action upon having detected the change in resistance.
