How to Dispose of Sharps
Needles, syringes, lancets, and scalpels are regulated sharps. Here is what counts, how to contain them, and how the rules change by state.
What counts as sharps
Under the OSHA bloodborne pathogens standard, contaminated sharps are "any contaminated object that can penetrate the skin including, but not limited to, needles, scalpels, broken glass, broken capillary tubes, and exposed ends of dental wires" (29 CFR 1910.1030). Sharps are one category of regulated waste, which also covers liquid or semi-liquid blood, items caked with dried blood that can release it when handled, and pathological and microbiological waste.
In a workplace, the OSHA standard governs. At home, self-injectors managing diabetes, allergies, or arthritis follow FDA consumer guidance instead, because OSHA applies to occupational settings. The practical rule is the same in both: a rigid, puncture-resistant container and an approved disposal route.
Step by step: containment, segregation, transport
- Contain at the point of use.
Drop each used sharp directly into an FDA-cleared sharps container the moment you are done. FDA-cleared containers are heavy-duty plastic, leak-resistant, upright and stable, with a tight-fitting puncture-resistant lid. If no cleared container is available, FDA accepts a heavy-duty plastic household container such as a laundry-detergent bottle as a temporary alternative. Never use glass or a thin plastic bottle.
- Do not recap, bend, or break.
CDC and OSHA both say not to recap, bend, break, or remove contaminated needles before discarding them. Recapping is a leading cause of needlestick injuries. Place the whole sharp, needle and all, into the container.
- Segregate from other waste streams.
Sharps go in the sharps container, not the red bag and not the regular trash. In a facility, keep sharps containers at the point of use, label them with the biohazard symbol, and do not mix sharps with pharmaceutical or chemotherapy waste, which have their own containers.
- Seal at three-quarters full.
Close the container at its marked fill line, or about three-quarters full if there is no line. Overfilling forces hands near exposed needles and causes injuries.
- Ship or drop off by an approved route.
Use a drop-off site (pharmacy, hospital, health department, or medical-waste facility), a mail-back program, or household hazardous-waste collection. Facilities shipping regulated medical waste off-site must meet DOT packaging rules for UN3291 (49 CFR 173.197). Mail-back kits ship through USPS under Publication 52, Packaging Instruction 6D.
Container, color code, and labeling
OSHA requires warning labels on containers of regulated waste. The labels carry the universal biohazard symbol and must be "fluorescent orange or orange-red or predominantly so, with lettering and symbols in a contrasting color" (29 CFR 1910.1030(g)(1)(i)). A red bag or red container may be substituted for the label. After collection, sharps are typically treated by autoclaving (steam sterilization) or incineration, then landfilled. EPA notes that most potentially infectious medical waste was incinerated before 1997, with autoclaving now far more common.
Sharps rules by state
Federal rules set the floor. States add their own requirements. A sample below; see each state regulation page for the full schema.
| State | Notable rule | Source |
|---|---|---|
| California | Prohibited in household trash. Statewide manufacturer-funded take-back with free mail-back at point of sale (HSC 118286; SB 212). | [source] |
| Massachusetts | Prohibited in household trash since July 1, 2012. Use a drop-off or mail-back program (105 CMR 480). | [source] |
| New York | Allowed in household trash under state law (local law may prohibit). Hospitals and nursing homes must accept home sharps (PHL 1389-dd). | [source] |
| Texas | Allowed. Household-dwelling sharps may go in regular municipal trash if contained; loose needles are not allowed (30 TAC 326). | [source] |
| Florida | Allowed in a sealed rigid container placed in the center of the trash. Loose or unprotected needles prohibited (64E-16 FAC). | [source] |
| Washington | Prohibited only where a source-separated residential sharps collection service exists (70A.228 RCW). Not a flat statewide ban. | [source] |
Frequently asked questions
Can I throw needles in the regular trash?
Loose needles should never go in household trash or recycling. Whether a sealed sharps container can go in the trash depends on your state. California and Massachusetts ban it outright, while Texas, Florida, and (under state law) New York allow a sealed rigid container in the trash. Always follow your state and community rules, because the federal government leaves home sharps disposal to the states.
What can I use as a sharps container at home?
Use an FDA-cleared sharps container: heavy-duty plastic, leak-resistant, with a puncture-resistant tight-fitting lid, upright and stable, and labeled. If one is not available, FDA says a heavy-duty plastic household container such as a laundry-detergent bottle can work as a temporary alternative. Never use glass or a thin plastic bottle like a soda bottle.
When is a sharps container full, and what do I do then?
Stop filling at the marked fill line, or about three-quarters full if there is no line. Overfilling causes needlestick injuries. Then seal it and dispose of it through an approved route: a drop-off site such as a pharmacy, hospital, or health department, a mail-back program, or household hazardous-waste collection.
Should I recap or break the needle before disposal?
No. CDC and OSHA both say not to recap, bend, break, or remove needles before discarding them. Drop the whole sharp directly into the container. Recapping is one of the leading causes of needlestick injuries.
