To find a good studio you should do some research on your own and talk to people you know and get references. It is commonly said that a good studio should be equipped with an autoclave which is a device that pressurizes the instruments and kills any viruses or bacteria. It is recommended that a good studio should have germicidal soap, needle buckets, proper disposal containers, packaged gauze with sterility intact, disposable gloves and check to be sure the studio is clean. Ask to see their permits if they are not displayed on the walls and be sure they are current. The equipment used by the studio should be individually packaged, dated, sealed and sterilized. The tattoo artist should disinfect the work area on your skin with an EPA approved virucidal that will kill any surface bacteria or viruses.
Occupational Safety and Health Administration’s Universal Precautions should be followed by the studio. These are regulations that outline procedures to be followed when dealing with bodily fluids.
