Medical Waste Disposal for Tattoo and PMU Studios in California: Sharps, Storage Limits and Records

Every tattoo, permanent makeup and piercing studio produces sharps. What you do with them after a procedure is spelled out in California law, and it is one of the first things an inspector asks to see proof of. The rules come from two places: the Safe Body Art Act, which has its own sharps rules for body art facilities, and the Medical Waste Management Act, which may also apply depending on your county.

This guide explains both, so you can set up a disposal routine that holds up at inspection.

What counts as sharps waste in a body art studio

The Safe Body Art Act defines sharps waste as any device with “acute, rigid corners, edges, or protuberances capable of cutting or piercing the skin” that has been used in body art and has not been disinfected or sterilized (§119301). In practice that means:

• Tattoo needles, cartridges and needle bars
• Permanent makeup needles and cartridges
• Microblading blades and disposable microblading pens
• Piercing needles
• Disposable razors

Sharps containers: what the law requires

• One in every procedure area, within the artist’s reach. It can be portable if that’s what it takes (§119314(e)).
• The right container. A rigid, puncture-resistant, commercially made sharps container that is leak-resistant when sealed and can’t easily be reopened (§119301).
• Labeled with the words “sharps waste” or the international biohazard symbol and the word “BIOHAZARD.”
• Not overfilled. California law doesn’t name a fill line, but federal OSHA says sharps containers must be kept upright, replaced routinely and never allowed to overfill (29 CFR 1910.1030). Most manufacturers and counties use the ¾ fill line printed on the container.
• Whole devices go in whole. Microblading hand tools go into the container intact unless the blade can be ejected (§119311).

Your three legal disposal options

Section 119314(e) gives body art facilities these choices for sharps:

1. A licensed medical waste hauler that takes the containers to a licensed treatment facility. You receive a tracking document at each pickup.
2. A mail-back system. The law refers to systems authorized by the California Department of Public Health. CDPH stopped approving new mail-back systems on January 1, 2015, and now requires them to meet U.S. Postal Service mailability standards, so check that any mail-back kit you buy meets current USPS rules and that your county accepts it.
3. Disinfection by a CDPH-approved method, after which the waste can go out as solid waste.

For most small studios, a scheduled hauler pickup or a mail-back program is the practical answer. Throwing sharps in the regular trash is never allowed.

How long you can store waste

If your waste is covered by the Medical Waste Management Act, these storage limits apply (§§118280, 118285):

• Full sharps containers: tape them shut or close the lid tightly, and store them no more than 30 days without written approval from your enforcement agency.
• Biohazard bag waste kept above freezing: 7 days if you produce 20 pounds or more a month; 30 days if you produce less than 20 pounds a month.
• Biohazard waste kept at or below 32°F: up to 90 days.

Weigh one month of biohazard waste to know which limit applies to you. If you produce under 20 pounds a month, plan pickups around the 30-day rule.

Do you need to register as a medical waste generator?

This is the question that confuses most studio owners, because the answer depends on your county.

• The Medical Waste Management Act (§117600 and following) doesn’t mention body art. Its definition of sharps refers to waste “generated in a health care setting.”
• Some counties read tattoo and piercing devices out of the Act. Ventura County’s generator guide, for example, lists ear and body piercing and tattoo devices among items not considered sharps waste under the MWMA. Those counties rely on the Safe Body Art Act rules above.
• Other counties require small quantity generators (under 200 pounds a month) to register by local ordinance. San Diego County is one example.
• Where CDPH is the enforcement agency, a small quantity generator without onsite treatment pays a $25 annual fee.

The safe move: call your county’s medical waste program (often part of environmental health) and ask whether a body art facility of your size must register. Sacramento County, for instance, tells businesses to call for a determination. Note the answer and the date in your records.

Records to keep

• Proof of sharps disposal for three years, available to the inspector on request (§119314(e)). This includes hauler tracking documents or mail-back receipts.
• If you are an unregistered small quantity generator, keep a short written description of how your waste is contained, stored, treated and disposed of, plus shipping records for at least three years (§117945).
• Your Infection Prevention and Control Plan must include safe handling and disposal of sharps (§119313).

Counties disagree on whether tracking documents must be kept two or three years. Keeping them three years satisfies both.

Conventions and temporary events

At a permitted temporary event, the event sponsor must provide sharps containers and have them removed by a licensed hauler (§119318). Artists still need to use a labeled container at their own station.

Needlestick while handling waste?

A sharps injury can happen during cleanup and disposal, not just during the procedure. If it happens, follow your exposure plan immediately; our step-by-step guide to what to do after a needlestick walks through it. Exposure response is also a required topic in annual bloodborne pathogens training.

Frequently asked questions

Can I throw used tattoo needles in the trash if I put them in a bottle?

No. Sharps from tattooing, piercing and permanent cosmetics must go to a licensed hauler or mail-back system, or be disinfected by an approved method first.

What is the best medical waste disposal option for a small tattoo studio?

It depends on your volume. Compare quotes for a mail-back sharps program and for scheduled hauler pickups, and choose a schedule that keeps full containers within the 30-day storage limit.

How full can a sharps container get?

Replace it when it reaches the fill line printed on the container, typically ¾ full. Never push sharps down to make room.

Do I need red bags?

Biohazard bags are for biohazardous waste, such as items saturated with blood, and must be labeled. Exactly which items count as biohazardous versus regular trash is set by your county, so ask your environmental health department and write the answer into your IPCP.

Keep your team trained

Sharps handling, labeling and disposal are part of the bloodborne pathogens training every California body art practitioner must renew each year. Our online BBP certification for tattoo and PMU artists covers them in a two-hour course with a same-day certificate.
