Safety Testing of Microwave Ovens
09 December 2020
Environmental Health Officers are increasingly coming across old microwave ovens as they age with splashed internal ceilings, blistering and rusting paint and the possibility safety mesh seals might be breaking down. Sometimes the wheel track under the revolving plate has just about rusted away. When microwave ovens first came out then EHO's used to carry a little tool that evidently lit up when leakage was detected. Always put a microwave safe container of water in to load the microwave when testing or you can damage the microwave oven. Take care with old cups because the superheated steam in a crack can cause a delayed explosion sometimes as you take them out of the microwave. Now there are a massive range of hand held digital microwave testing tools available.
Just like test and tag for electrical appliances, some service commercial service providers extend this to testing there is no radiation leakage from microwave ovens above acceptable limits.
I have asked Energysafe who does the ongoing testing of commercial kitchen microwave ovens if we ever suspect there may be problems.
I will let you know their response. Generally newer microwaves with give more reliable defrosting and cooking that are important for food safety as well as user safety.
