The definition and scope of Regulated Medical Waste (RMW) vary slightly by state, but at the federal level, OSHA and DOT provide broad classifications, and states adopt more specific lists.
RMW is also sometimes referred to as "infectious waste" or "biohazardous waste."
ℹ️ Federal Definition (Key Sources):
OSHA (29 CFR 1910.1030 – Bloodborne Pathogens Standard) defines regulated waste to include:
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 caked with dried blood or OPIM that could release these materials during handling
Contaminated sharps
Pathological and microbiological wastes containing blood or OPIM
DOT (49 CFR Parts 171–173) refers to these materials as Category B Infectious Substances (UN 3291) when transported and requires special packaging and labeling.
🔢 Types of Regulated Medical Waste
🔹 Sharps Waste
Sharps are any object capable of puncturing or cutting the skin, and when contaminated, are a form of regulated medical waste, which includes:
Used needles
Syringes with needles attached
Lancets
Scalpel blades
Broken glass vials contaminated with blood or bodily fluids
Suture needles and other surgical sharps
Key compliance considerations for sharps waste disposal:
Sharps must be disposed of in rigid, puncture-resistant, leak-proof sharps containers.
Containers with sharps must be labeled with the biohazard symbol or marked according to DOT and OSHA requirements.
Disposal of sharps via mail-back systems (e.g., PureWay) or pickup services must comply with USPS Publication 52 (if mailed) and DOT regulations.
🔹 Biohazardous Waste (Non-sharps RMW)
Biohazardous waste is any non-sharp material contaminated with potentially infectious agents, which includes:
Blood-soaked bandages
Surgical gloves and gowns contaminated with blood or OPIM
Cultures and stocks from laboratories
Pathological waste (e.g., human tissues, organs)
Body fluids are visibly contaminated with blood.
Key compliance considerations for biohazardous waste disposal:
Biohazardous waste must be disposed of in leak-proof, labeled red bags and then secondary containment (e.g., boxes or tubs) for transport.
Biohazardous waste must follow OSHA, DOT, and state-specific handling, storage, and transportation regulations.
📌 Differences Between Sharps and Biohazardous Waste
Category | Sharps Waste | Biohazardous Waste |
Definition | Items that can puncture skin and are contaminated with blood or OPIM | Contaminated non-sharp items with blood or OPIM |
Examples | Needles, syringes, scalpels, broken and contaminated glass | Blood-soaked dressings, gloves, suction canisters |
Container Type | Rigid, puncture-proof sharps containers | Leak-proof red biohazard bags |
Transport Class | UN3291 – Infectious Substance, Category B | UN3291 – same classification |
Disposal Method | Incineration or autoclaving | Incineration, autoclaving, or other state-approved treatment |
