Safety Precautions When Using Microwave Ovens

You may very well have heard that microwave ovens are unsafe. However, most people’s fears are unfounded. To date no-one has proven a relationship between cancer or any illness and microwaves. There was an investigation in the late 1980s that is responsible for many of the fears that people have, but even that wasn’t decisive. Though there are a few safe practices that you ought to observe in using present day microwave ovens, the judgment of researchers is that they are basically safe.

Microwaves Do Not Cause Cancer

There are no recorded cases of cancer, or any other illness, being brought on by the use of microwave ovens. The fact is, the form of radiation put off by a microwave is non-ionizing – the opposite of X-rays and other radiation that can trigger cancerous conditions. Yet, even if radiation isn’t a problem, there are other potential safety concerns you should think about. Just like all cooking tools, microwaving is not completely danger-free.

Heating Liquids Requires Especial Care

Fluids, for example, when warmed in a microwave container with a smooth surface, can rapidly overheat. Paradoxically, they may well rise to a temperature higher than boiling point without actually boiling. Adding other material or moving the container will disturb the fluid, at which point it could begin to boil violently. The resulting sudden burst of water and steam can cause serious scalding. This has been confirmed using distilled water, but superheating can take place with other liquids, such as coffee or tea.

Be Sure Egg Shells are Pierced

Apart from fluids, some other foodstuffs can be hazardous, as well. Containers that aren’t suitably vented might burst inside a microwave – the same goes for food like eggs or potatoes which have a shell or skin. Without proper ventilation, steam can accumulate inside. With no means to escape, an explosion may possibly be the result. The food will explode under the pressure in the end. This leads to a big mess and may also result in burns. Foods that have been heated for a long time may well actually catch fire, too.

Never Put Metal in a Microwave

Most people know they should not put metal inside a microwave oven. Arcing electricity or sparks can occur when an electric charge is generated because the metal in the object is resonating. You should be careful with takeout foods – accidentally microwaving a box with a metal handle, or a twist tie with a wire inside, can result in fires. Be careful to remove any metal from your microwave before using it, to avoid the possibility of fire.

Other Things to Bear in Mind

You must also be careful not to use your microwave oven while it’s empty. Running your microwave without anything inside to absorb the radiation will result in the formation of a standing wave inside. This energy can burn out your microwave when it gets reflected between the cooking chamber and the tube. This is a further reason why you should not microwave food inside a metal wrapping or food that has been dried out. These materials will reflect the wave, rather than absorbing it.

If foods are arranged improperly, they may arc. Grapes are an example of this. Fire inside the microwave is likely to also produce a spark of electricity – never put anything that’s on fire inside your oven. Handle all foods carefully – even when they don’t appear to be hot. They may be hotter than they seem, and fluids can be particularly dangerous. Handling your microwave with proper care will enable you to produce delicious, safe food. So, the bottom line is that you can prepare food with a microwave oven with the knowledge that it will present no risks when used correctly. Just remember the points mentioned in this article, as microwaves require a few special precautions, much like any other cooking technique.
