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
Test your knowledge on the management and disposal of radioactive waste, including unused liquids from radiotherapy, contaminated materials, and waste from patients treated with radionuclides. Learn about recyclable, biodegradable, and non-recyclable/non-biodegradable waste disposal methods.
