User Guide: How to Use Biohazard Waste Bags
Step-by-Step Instructions
- Select the Correct Bag: Choose the appropriate color-coded bag based on the type of waste you are disposing. Verify bag is intact with no tears or holes.
- Proper Container Placement: Place the bag inside a sturdy, rigid container or bin with a foot-pedal lid. The bag should line the entire container with edges folded over the rim.
- Segregate Waste Properly: Dispose only the designated waste type in each color-coded bag. Never mix different categories of waste.
- Fill to Safe Capacity: Fill bag only to three-quarters full or the marked fill line. Overfilling increases risk of tears and spills.
- Remove Air: Gently press out excess air from the bag before sealing to reduce volume and prevent bursting.
- Seal the Bag Securely: Use a gooseneck tie or secure closure method. Twist the top of the bag and fold it over, then tie securely. Some bags have built-in closure strips or ties.
- Label Appropriately: Mark the bag with date, department, and contents if required by your facility protocol. Ensure biohazard symbol is visible.
- Handle with Care: Hold the bag by the sealed top, away from your body. Never carry bags over your shoulder or drag them on the ground.
- Place in Designated Area: Move sealed bags immediately to the designated biohazard waste storage area. Do not leave in patient care areas.
- Maintain Hand Hygiene: Always wash hands thoroughly or use alcohol-based sanitizer after handling biohazard waste bags, even when wearing gloves.
Waste Segregation Guidelines
| Waste Category | Correct Disposal Method |
|---|---|
| Used needles and sharps | First place in puncture-proof sharps container, then container goes in red/yellow bag when full |
| Blood-soaked gauze, bandages | Red or yellow biohazard bag |
| Contaminated gloves, masks, gowns | Red or yellow biohazard bag |
| Expired medications | Yellow or blue pharmaceutical waste bag |
| Clean paper, food wrappers | Black general waste bag |
| Laboratory cultures, specimens | Red or yellow biohazard bag, autoclave if needed |
