Is putting it in a toaster the best solution?
If you use the same toaster that everyone else uses for their wheat-based bread, then you are asking for trouble.
There are two safe solutions.
This is a good and convenient solution.
Be sure to clearly mark the toaster as gluten-free. If there is any chance that this sign might be ignored, then store the toaster well away from your wheat-consuming friends and family when it is not being used to toast your own gluten-free bread.
If you only make toast occasionally, you can use a frying pan to toast your gluten-free bread.
This works reasonably well, although not as well as a toaster, and you have to baby-sit the bread, which is not convenient. It is actually the method I use since I so rarely eat toast.
The main thing is never to put your gluten-free/wheat-free bread anywhere near a gluten- or wheat-contaminated source.
Also, watch out for other potential causes of cross-contamination such as tongs/toast-tweezers, and toast-cooling racks.
These items could be shared if properly washed after use with wheat-based bread. The problem with this approach is that you may forget, or depend on others who may overlook this step.
Again, it may be better to use your own implements when handling your gluten-free toast.
