Microwave Safety

Often the largest concern potential users have when considering implementing microwave systems is microwave safety. Because, after all, isn’t microwave energy dangerous?

The answer is yes, but not as dangerous as a conventional oven or virtually any other piece of industrial equipment.


Often the largest concern potential users have when considering implementing microwave systems is microwave safety. Because, after all, isn’t microwave energy dangerous?

The answer is yes, but not as dangerous as a conventional oven or virtually any other piece of industrial equipment.

In closed batch microwave systems, door sensors with automatic shutdowns ensure that while the system is running users are not exposed to electromagnetic energy. In the case of a continuous belt-fed tempering system chokes and leak detectors wired with automatic shutoffs ensure the same level of safety. In compliance with OSHA safety standards, we limit the amount of leakage to 5 mw/cm2 measured 5 cm away from the equipment, twice as stringent as OSHA’s voluntary standard.

Also, microwaves are a form of non-ionizing radiation which means that they create no lasting effect (as opposed to ionizing radiation like that emitted from radioactive materials, which can permanently change exposed materials). That means when you turn off the system, everything is exactly as it was except the material you treated which is now the desired temperature.

Arcing, the effect you’ve seen in your home microwave if you accidentally leave a fork in, occurs from time to time for a variety of reasons. However, all systems manufactured by Ferrite Microwave Technology and leading competitors feature arc detectors that shut the system down at the first sign of trouble. All these safety measures ensure that industrial microwave systems are as safe, if not safer, than other industrial machinery.

Fear is often born of misinformation or ignorance. Now that you know the facts about microwave safety, it is easy to understand why practitioners in our industry often forget how many people harbor safety concerns associated with microwave technology. If you have specific questions not addressed above, please don’t hesitate to spell them out in the comments and we will be sure to address them.
