None of us can control nature, and when nature calls we must answer. When it comes to sanitary napkins and sanitary napkin disposal, it is important to be courteous and safe and practice proper disposal.
In most women's restrooms, there are special units for sanitary napkin disposal. These should be kept separate from the regular trash because of their possibly hazardous nature. If you are using a women's restroom, be sure to use the right receptacle for sanitary napkin disposal.
Whatever you do, don't practice sanitary napkin disposal by flushing yours down the nearest toilet, any public restroom feminine hygiene guide will tell you that. While some sanitary napkins are made to be flushed, the materials used in most sanitary napkins are meant to absorb and do so when clogging a toilet. Think about the person who will have to unclog that toilet the next time you are thinking of doing this.
Practicing proper sanitary napkin disposal is important for safety and should always be observed.
