Body piercing is an invasive process that presents the potential for spreading blood-borne diseases, such as Hepatitis B. Operators and artists are trained. They are required to register once and then maintain an annual permit. Body art facilities - both permanent and temporary- must obtain and maintain a public health permit to operate, and are inspected by by an Environmental Health Specialist from the DEH. Minors under the age of 18 years of age must have a notarized consent form and be accompanied by a parent or legal guardian. The facility must display their current permit.
