10. A method for detecting a hazardous condition, the method comprising: receiving sensor readings from a plurality of sensors for attributes related to the hazardous condition; and determining whether the hazardous condition exists based on a fuzzy analysis of the sensor readings, wherein: the sensor readings include temperature readings: and the fuzzy analysis comprises: determining a temperature rise rate from the temperature readings; classifying the temperature rise rate by assigning a classification value in the range 0 to 1; categorizing the temperature rise rate and the temperature readings into respective fuzzy set categories; and combining the respective fuzzy set categories into an output that indicates whether the hazardous condition exists or not.
