Sharps containers are a fundamental component of any safe medical waste management program, yet confusion about what should go in them remains surprisingly common. Putting the wrong items in these containers (or the right items in the wrong ones) can pose serious risks to healthcare workers, patients, and waste handlers alike.
At Healthcare Medical Waste Services (HMWS), we've been helping Arizona's medical community safely and compliantly manage regulated waste since 1998. This guide covers exactly what goes into a sharps container, what should never go in one, and how to ensure your facility stays on the right side of OSHA and FDA regulations.

Why Knowing What Goes in a Sharps Container Matters
Before diving into specifics, it's worth understanding the stakes. Sharps (needles, scalpels, lancets, and similar instruments) can transmit bloodborne pathogens, including HIV, Hepatitis B, and Hepatitis C, if they puncture the skin after contact with infected blood or body fluids. Needlestick injuries are one of the most common and preventable occupational hazards in healthcare.
Improper disposal creates cascading risks:
Needlestick injuries to healthcare workers, janitorial staff, and waste handlers
Regulatory non-compliance with OSHA Bloodborne Pathogen Standards and state-level requirements
Environmental contamination when sharps enter the general waste stream
Increased liability for your facility
Correct sharps disposal starts with knowing precisely what goes in sharps containers and what doesn't.
What Goes in a Sharps Container: The Complete Breakdown
According to OSHA's Bloodborne Pathogens Standard (29 CFR 1910.1030), a "sharp" is any object capable of penetrating a worker's skin. When these objects are contaminated with blood or other potentially infectious materials (OPIM), they must be placed directly into an approved, puncture-resistant sharps container.
Here is a detailed breakdown of what goes in a sharps container:
1. Needles and Syringes
This is the most commonly disposed of item. Used needles (whether from injections, blood draws, IV lines, or medication administration) must be placed directly in the sharps container immediately after use. The key rule: do not recap, bend, or remove the needle from the syringe. Place the entire connected device into the container. This single practice dramatically reduces the risk of accidental needlestick injuries.
Examples include:
Hypodermic needles
IV catheters and needles
Insulin syringes
Blood collection needles
Spinal and epidural needles
2. Lancets
Lancets, the small, retractable devices used to prick fingers for blood glucose testing or blood collection, are considered sharps and should be placed in a sharps container. This applies whether they are used in a clinical setting or at home by a patient.
3. Scalpels and Blades
Used surgical scalpels and detached blades are sharps. In surgical or procedure settings, scalpel blades should be removed using a blade removal tool (never bare fingers) and immediately placed in the sharps container. In some facilities, entire scalpel units are deposited directly into a rigid container without removing the blades.
4. Glass Capillary Tubes
Broken or unbroken glass capillary tubes, particularly those used in blood collection or laboratory diagnostics, qualify as sharps because they can puncture skin. Contaminated capillary tubes should always be disposed of in the sharps container.
5. Broken or Contaminated Glass
Any glass item that has been contaminated with blood or OPIM and poses a puncture or laceration risk belongs in a sharps container. This includes broken glass vials, ampoules, and slides from clinical or laboratory settings.
6. Dental Wires and Orthodontic Instruments
OSHA specifically includes "exposed ends of dental wires" in its definition of sharps. Used dental instruments that are sharp and potentially contaminated (including orthodontic wires, certain probes, and irrigation needles) should be disposed of in a sharps container.
7. Auto-Injectors and Prefilled Syringes
Epinephrine auto-injectors (like EpiPens), insulin pens, and other prefilled delivery devices contain retractable or exposed needles after use. The entire device — needle and body — should go directly into the sharps container.
8. Trocars and Bone Marrow Biopsy Needles
Larger invasive needles used in procedures such as thoracentesis, paracentesis, or bone marrow biopsies are considered sharps and must be disposed of in an appropriate container, often a larger-capacity model suited for these instruments.
What Should NOT Go in a Sharps Container
Understanding what goes in sharps containers is only half the equation. Equally important is knowing what to keep out.
Do not place the following in sharps containers:
Uncontaminated PPE: gloves, gowns, masks, and face shields that haven't been exposed to sharps or OPIM belong in regular medical waste or general trash, as appropriate
Regular solid waste: paper, packaging, and non-contaminated disposables must not enter the sharps stream
Pharmaceutical waste: unused or expired medications require separate pharmaceutical waste disposal (HMWS provides dedicated Pharmaceutical waste disposal services for Arizona healthcare facilities)
Chemotherapy waste: chemo drugs and contaminated items require specially designated chemo waste containers, not standard sharps containers
Pathological waste: tissues, organs, or other biological specimens do not belong in a sharps container
Large volumes of liquids: Sharps containers are not designed to hold significant volumes of fluid; excessive liquid can compromise container integrity
Misusing sharps containers for non-sharp waste shortens container life, increases disposal costs, and raises the risk of overfilling, which in turn increases the chance of needlestick injuries and potential regulatory violations.
How to Use a Sharps Container Correctly
Knowing what goes in a sharps container is only the first step. Proper technique matters too.
Placement Guidelines
Place the sharps container as close to the point of use as possible — a container on the other side of the room invites shortcuts
Mount containers at a height that allows for easy, one-handed depositing without looking into the container
Never reach into a sharps container with your hand or fingers
Fill Level Management
The FDA recommends that sharps containers be replaced when they are approximately three-quarters (3/4) full. Overfilling a sharps container significantly raises the risk of needlestick injuries and is a common compliance violation. Once a container reaches the fill line, it should be sealed and scheduled for professional pickup, never manually opened or emptied by facility staff.
Labeling and Sealing
Sharps containers must be clearly labeled with the universal biohazard symbol and the word "SHARPS" or equivalent language. When sealing a container for disposal, engage the lid closure mechanism fully to prevent leakage during transport.
Secondary Containment
If there is any risk of a sharps container leaking, for example, if a container has been damaged or is being transported, OSHA requires placement into secondary containment. Secondary containers must be closable, leakproof, and color-coded or labeled appropriately.
Container Types: Matching the Right Container to the Right Waste
Not all sharps containers are the same. Choosing the appropriate container size and type for your clinical setting is an important part of effective sharps management.
Container Type | Typical Use Case |
|---|---|
Small tabletop (1–2 qt) | Point-of-care rooms, exam rooms, and home use |
Medium floor-standing (3–5 gal) | Nursing stations, procedure rooms |
Large floor-standing (8–18 gal) | Operating rooms, emergency departments |
Wall-mounted units | High-traffic injection areas |
Chemotherapy-specific containers | Oncology units, chemo preparation areas |

Regulatory Framework: Who Governs Sharps Disposal?
Several federal and state agencies set the standards for sharps disposal. Key governing bodies include:
OSHA — Establishes workplace safety standards for handling and disposing of contaminated sharps under the Bloodborne Pathogen Standard
FDA — Regulates the design and manufacturing standards for sharps containers used in healthcare facilities
EPA — Oversees environmental compliance related to medical waste disposal
State health departments — Arizona has its own regulations governing medical waste generators, transport, and treatment that supplement federal standards
DOT — Sets rules for the safe transport of regulated medical waste, including sealed sharps containers
Healthcare facilities in Arizona are required to work with a licensed and permitted medical waste company for the pickup, treatment, and disposal of sharps containers. HMWS is fully licensed and permitted to handle this process end-to-end.

FAQs
1. What goes in the sharps container in a dental office?
In a dental setting, items that go in the sharps container include anesthetic cartridges (if broken or containing blood), orthodontic wires, scalpel blades, and needles used for injections. Even small wire fragments that can puncture skin should be treated as sharps.
2. Can I put plastic syringes without needles in a sharps container?
While a needle-less syringe isn't "sharp," many facilities prefer to keep the syringe and needle together as a single unit to prevent unnecessary manipulation. If the needle has been removed (using a safety device), the syringe body may sometimes go into a red bag, but check your local state regulations, as many require the entire assembly to go into the sharps bin.
3. What goes in sharps containers regarding "safety needles"?
Regardless of whether a needle has a "safety" feature or a retractable sleeve, it must be placed in a sharps container. These safety mechanisms can fail, and the item still meets the definition of a medical sharp.
4. How do I dispose of a sharps container when it's full?
Once the container reaches the fill line, it must be permanently locked/sealed. You should then contact a licensed medical waste provider, such as HMWS, to schedule a pickup. Never place a sealed sharps container in the regular trash.
5. What goes in a sharps container for home use?
For patients managing conditions like diabetes or infertility at home, what goes in a sharps container includes lancets, insulin pens, and needles. You can purchase puncture-resistant containers at most pharmacies or use HMWS mail-back services for easy disposal.
6. Are glass IV bottles considered sharps?
If the glass bottle is broken and contaminated with blood or infectious fluids, it belongs in the sharps container. If it is intact and contains non-hazardous medication, it may be classified as pharmaceutical waste. If it is empty and unbroken, it may follow standard glass-recycling or disposal rules, depending on the facility's policy.
