How to Dispose of Red-Bag / Biohazard Waste
What legally belongs in a red bag, how OSHA defines regulated waste and OPIM, and how regulated medical waste is packaged, transported, and treated before it reaches a landfill.
What counts as red-bag / biohazard waste
OSHA's Bloodborne Pathogens standard defines the red-bag stream as regulated waste, meaning liquid or semi-liquid blood or other potentially infectious materials (OPIM); contaminated items that would release blood or OPIM in a liquid or semi-liquid state if compressed; items that are caked with dried blood or OPIM and are capable of releasing these materials during handling; contaminated sharps; and pathological and microbiological wastes containing blood or OPIM (29 CFR 1910.1030(b)). Blood means human blood, human blood components, and products made from human blood. OPIM includes specified human body fluids (such as semen, cerebrospinal fluid, synovial fluid, saliva in dental procedures, and any body fluid visibly contaminated with blood), any unfixed human tissue or organ other than intact skin, and HIV or HBV cultures (29 CFR 1910.1030(b)).
Step by step: containment, segregation, transport
- Segregate at the point of generation.
Put only OSHA regulated waste into the red bag. A glove or bandage with a small amount of dried blood that will not release in a liquid or semi-liquid state if compressed is not regulated waste under 29 CFR 1910.1030(b); routine, non-saturated trash stays in regular waste so you are not overfilling expensive red-bag streams.
- Use compliant containers.
Place regulated waste in containers that are closable, constructed to contain all contents and prevent leakage of fluids during handling, storage, transport, or shipping, and labeled or color-coded per 1910.1030(g)(1)(i). Contaminated sharps go in containers that are closable, puncture-resistant, and leakproof on the sides and bottom (29 CFR 1910.1030(d)(4)(iii)).
- Label or color-code.
Mark containers with the biohazard symbol on a fluorescent orange or orange-red label with contrasting lettering, or substitute red bags or red containers, as allowed by 29 CFR 1910.1030(g)(1)(i). Close containers before removal to prevent spillage or protrusion of contents.
- Hand off to a registered transporter.
A registered medical-waste transporter ships the waste as Regulated medical waste, UN3291, Division 6.2, in rigid UN standard Packing Group II packagings. Sharps packagings must be puncture-resistant, and large packagings for liquid waste must hold enough absorbent material to absorb the entire amount of liquid present (49 CFR 173.197).
- Treat, then landfill.
A permitted facility treats the waste by steam sterilization (autoclaving) or incineration. After steam sterilization, CDC notes the residue can be handled and discarded with other nonhazardous solid waste, so decontaminated waste then goes to a sanitary landfill in accordance with state solid-waste regulations.
Container, color code, and labeling
Red is the recognized color for this stream because OSHA permits red bags or red containers to be substituted for biohazard labels (29 CFR 1910.1030(g)(1)(i)); where labels are used instead, they must carry the biohazard symbol in fluorescent orange or orange-red with contrasting lettering. Containers must be closable, leak-resistant, and closed before removal, and sharps containers must additionally be puncture-resistant and leakproof on sides and bottom (29 CFR 1910.1030(d)(4)(iii)). Once collected, regulated medical waste is treated before final disposal: steam sterilization in an autoclave (CDC notes exposure of up to 90 minutes at 250 degrees Fahrenheit (121 degrees Celsius) may be needed depending on load size and container), or incineration in a unit engineered to burn the waste completely within EPA emissions standards. After treatment renders it non-infectious, the residue is landfilled with other nonhazardous solid waste under state rules.
Frequently asked questions
Does every bloody glove or bandage go in the red bag?
No. OSHA's definition of regulated waste covers items that would release blood or OPIM in a liquid or semi-liquid state if compressed, or that are caked with dried blood or OPIM and capable of releasing it during handling (29 CFR 1910.1030(b)). A glove or bandage with light, dried, non-releasable blood does not meet that definition and is not regulated waste, so over-bagging routine trash is both unnecessary and costly.
Can I pour liquid blood down the drain or put it in regular trash?
Liquid or semi-liquid blood and OPIM are regulated waste and must not go in regular trash (29 CFR 1910.1030(b) and (d)(4)(iii)). For sink or sewer discharge, CDC notes that discharging small quantities of blood and body fluids to the sanitary sewer is considered a safe method where local sewer authorities permit it; confirm your state and local rules first.
How is red-bag waste shipped, and does it need a special label?
It ships as Regulated medical waste, UN3291, a Division 6.2 infectious substance (49 CFR 173.134). Packagings must be rigid UN standard Packing Group II containers, sharps packagings must be puncture-resistant, and large packagings for liquid waste must contain enough absorbent material to absorb the entire amount of liquid present (49 CFR 173.197).
Who regulates medical-waste disposal, OSHA or EPA?
EPA states it has not had authority specifically for medical waste since the Medical Waste Tracking Act of 1988 expired in 1991, and that medical waste is primarily regulated by state environmental and health departments. OSHA governs how generators contain and label the waste to protect workers (29 CFR 1910.1030), and DOT or PHMSA governs transport (49 CFR 173.197), so check your state program for treatment and disposal specifics.
