"Tattooing " involves the puncturing of the skin with a foreign object. To be safe, you must shop for tattoo artists like you would for a dentist. There are many things that tattoo artists must do to keep their work area clean and avoid contamination from blood-borne pathogens, since a small amount of blood is a normal part of the tattooing process. There are things you should look for in your prospective artist's studio, such as a neat and clean appearance, an autoclave and ultrasonic cleaner, a clearly labeled sharps container for used needles, plastic barriers on all tattooing equipment, and instruments that are taken out of autoclave pouches with proper sterility indicator. Your best bet when scouting for a new tattoo artist is to talk with them and ask questions about these things first. Any respectable tattoo artist will know all about the safety concerns of their craft, and should not have a problem answering some basic precautionary questions. Indeed, your tattoo artist should be way more concerned about being clean and safe than you are--after all, you deal with only one tattoo that day, but your artist is likely dealing with many people, every day. If the artist blows off questions or gives you vague answers, that’s never a good sign. If they are happy you are asking, answer your questions clearly, and show a genuine concern for safety then you are probably in good hands.
