Study Notes
Types of Waste
- Infectious waste: suspected to contain pathogens, includes laboratory cultures, waste from isolation wards, and materials in contact with infected patients
- Pathological and anatomical waste: human tissues, organs, or body fluids
- Sharps: sharp waste that can cause cuts, pricks, or punctures, includes needles, infusion sets, scalpels, and knives
- Pharmaceutical waste: expired, spilt, or contaminated pharmaceutical products
- Genotoxic waste: waste containing substances with genotoxic properties
- Chemical waste: waste containing chemical substances generated during disinfection and sterilization procedures
- Radioactive waste: waste containing radioactive substances
- Non-hazardous or general waste: waste that has not been in contact with communicable or infectious agents, hazardous chemicals, or radioactive substances
Waste Segregation and Storage
- Infectious waste: yellow container with biohazard symbol, 0.009mm thickness, and labelled "infectious waste"
- Pathological and anatomical waste: yellow container with biohazard symbol, 0.009mm thickness, and labelled "pathological/anatomical waste"
- Sharps: punctured-proof container with wide-mouth, labelled "sharps", and biohazard symbol
- Chemical waste: labelled "chemical waste", yellow with black band, 0.009mm thickness, and tagged with source and weight of waste
- Pharmaceutical waste: labelled "pharmaceutical waste", yellow with black band, 0.009mm thickness, and tagged with source and weight of waste
- Radioactive waste: radiation-proof repository, leak-proof, and lead-lined container, labelled with name of radionuclide and date of deposition
- General waste: optional recycle symbol, black or colorless plastic, 0.009mm thickness, and tagged with source and weight of waste
Guidelines for Proper Labelling, Marking, and Color Coding
- Use of biohazard symbol is optional
- Labeling and tagging of waste with source, weight, and date of collection
- Color coding: yellow for infectious, pathological, and anatomical waste; yellow with black band for chemical and pharmaceutical waste; orange for radioactive waste; black or colorless for general waste
Laboratory Safety and Waste Disposal
- Report accidents in the laboratory immediately
- Disinfect working area before and after laboratory procedures
- Practice proper disposal of waste materials inside the laboratory classroom
