Fires in microwave and RF heating systems are not uncommon. However, they are often avoidable or controllable once ignited.
It is important that manufacturers and users of microwave and RF processing equipment understand the causes of fires and means to prevent them if for no other reason than that the presence of electromagnetic energy can cause the fire to burn more vigorously. Flames are plasmas and are rich in free radicals. It has been shown that microwave and radio frequency energy can couple into hydrocarbon flame plasmas because of the high electron density that exists in the flame front as a result of chemical ionization. The result is the acceleration of chemical reactions due to the energized flame-front electrons. In other words the fire can burn hotter and more vigorously, which can increase its destructive effects.
WHAT TO DO IF A FIRE OCCURS:
[First,] Shut down microwave generators
