It has to be cleared that any household appliance can be a hazard. But toasters specifically tend to become more volatile as they get older. In case of not clearing a toaster regularly, the leftover crumbs inside gradually grow the potential to cause a hazardous fire. Regular usage and care of the appliance can prove efficient in the long run. The recommended maximum time for a toaster is six to eight years. One should refrain from using a toaster beyond that period.
