METHODS FOR MANAGING BIOLOGICAL WASTE

• Biological waste categories : Category A (sharp wastes)

  • Sharp instruments such as syringes, needles, glass, scalpel and other sharp instruments that can cause injuries
  • Placed into a special bin for sharp material disposal. This bin does not need to be sterilised.
• Category B(non-sharp wastes)

  • Biological solid waste such as gloves, tissue papers, petri dishes, plastic culture containers and hardened agar
  • Packed first in autoclave resistant biohazard plastic bags, sterilised in an autoclave for decontamination, and then placed into a biohazard bin. Biohazard plastic bags cannot be thrown into regular waste baskets.
• Category C(animal carcases)

  • Animal carcases, organs and tissues
  • Wrapped carefully in absorbent material (such as tissue papers), packed carefully into a biohazard plastic bag and frozen.
• Category D (liquids)

  • Broth culture and liquid medium such as blood
  • All biological liquid waste must be decontaminated by autoclaving before disposal. Sterilised biological liquid wastes must be disposed immediately.
