Proper Biohazard Waste Containment
Biohazard bags are required by OSHA (29 CFR 1910.1030) for the containment of regulated medical waste, including cultures, stocks, pathological waste, contaminated sharps, blood, and other potentially infectious materials (OPIM). Our bags are manufactured from heavy-duty polypropylene that withstands autoclave sterilization cycles without melting or losing structural integrity.
When autoclaving biohazard bags: (1) Leave the bag open or loosely closed to allow steam penetration—sealed bags can trap air and prevent sterilization. (2) Place bags in a secondary containment tray to catch leaks. (3) Use autoclave tape or a biological indicator to verify the sterilization cycle reached 121°C/15 psi for the required hold time (typically 30–60 minutes depending on load size).
Red bags are the universal standard for biohazardous waste in the United States. Orange bags are used in some facilities to differentiate waste streams (e.g., orange for autoclave-treated waste, red for waste going directly to incineration). Follow your facility’s specific color-coding policy for proper segregation.
Biohazard Bag FAQ
Standard biohazard bags are 1.5–2 mil thick. For heavy or sharp-edged waste (broken glass, solid agar plates), use 3–4 mil heavy-duty bags to prevent punctures during handling and transport. Thicker bags also better withstand the physical stress of autoclaving.
No. Loose sharps (needles, scalpels, broken glass) must be placed in rigid, puncture-resistant sharps containers. Biohazard bags are for solid and liquid biohazardous waste only. Sealed sharps containers can be placed inside biohazard bags for transport.
Yes. All our biohazard bags are printed with the universal biohazard symbol and the word "BIOHAZARD" in English and Spanish per OSHA labeling requirements. This ensures proper identification by waste handlers throughout the disposal chain.
We stock biohazard bags from 1.5-gallon (benchtop waste) through 7, 10, 14, and up to 33–35 gallon (large can liners). Choose the size that fits your waste receptacle—the bag should line the container with enough excess at the top to fold over and secure with tape or a twist tie.
