 Contemporary body piercing studios generally take numerous precautions to protect the health of the person being pierced and the piercer . Piercers are expected to sanitize the location to be pierced as well as their hands , even though they will often wear gloves during the procedure ( and in some areas must , as it is prescribed by law ) . Quite frequently , these gloves will be changed multiple times , often one pair for each step of setup to avoid cross contamination . For example , after a piercer has cleaned the area to be pierced on a client , the piercer may change gloves to avoid recontaminating the area with the gloves he / she used to clean it . Wearing sterile gloves is required by law for professional piercing procedures in some areas , such as the states of Florida and South Carolina . Tools and jewellery should be sterilized in autoclaves , and non @-@ autoclavable surfaces should be cleaned with disinfectant agents on a regular basis and between clients .
