Biohazard & Chemical Waste Management

Types of Biohazard Waste:

• Sharps: These include needles, scalpels, and broken glass contaminated with biological materials. Proper disposal involves using biohazard-marked sharps containers. 
• Liquid Biohazard Waste:  Bulk biological liquids like culture media and clinical specimen fluids should be collected in aspiration vacuum flasks charged with disinfectant.
• Solid Biohazard Waste: Items like contaminated gloves, pipettes, soiled kim wipes and petri dishes fall into this category.
• Tissue Biohazard Waste: Biological tissues, organs, and body parts require specific handling and disposal procedures.

Collection,  Storage and usage practices:

• Use biohazard-labeled containers designed to prevent accidental release.
• Sharps containers must be puncture-proof and leak-proof.
• Keep sharps containers free of visible contamination and store them upright.
• Liquid waste containers should be charged with disinfectant before use.
• Solid Biohazard waste containers should have lids and remain closed when not in use.

Treatment and Disposal:

• Permanently close sharps containers when 3/4 full or when items don’t freely fall in.
• Place full, sealed containers in designated biohazard waste pickup points.
• Your external vendors handle treatment and disposal of sharps containers

Regulations and Compliance:

• OSHA  and state regulations (e.g., 105 CMR 480.000 in Massachusetts) mandate  proper labeling, storage, and disposal of biohazardous waste.
• Familiarize yourself with local guidelines and follow autoclave safety protocols
• Generator paperwork must be kept for 3 years in an accessible location in the case of an inspection.

Remember, biohazard waste management protects everyone involved and ensures a safer environment. If  you have specific questions related to your waste handling practices,  consult your institution’s biosafety office or environmental health and  safety team.

 Best Practices in Chemical Waste Management:

• Organizations can limit chemical waste by: 
  • Reducing consumption through efficient processes.
  • Properly storing chemicals to prevent spills.
  • Recycling or reusing chemicals where possible.
  • Disposing of waste according to regulations.
  • Using UN rated storage containers is best practice.

 Regulations and Compliance: 

• Federal and state governments have strict regulations for chemical waste management.
• Conscientious handling of chemical waste is crucial to protect the environment.

Hazardous Waste Basics: 

• Hazardous waste is dangerous to health or the environment.
• The EPA regulates hazardous waste from generation to disposal.
• Recycling, treatment, and proper disposal are key components.

In summary, responsible chemical waste management ensures safety, sustainability, and a healthier future for all.  If  you have specific questions related to your waste handling practices,  consult your institution’s chemical hygiene officer or environmental health and safety team.
