Hazardous waste can be defined as…
waste that has the potential, even in low concentrations, to have a significant adverse effect on public health and the environment because of its inherent toxicological, chemical and physical characteristics

PRINCIPLES OF WASTE MANAGEMENT
• Duty of Care Principle
• Polluter Pays Principle
• Precautionary Principle
• Sustainable Development
![Page 8: HAZARDOUS WASTE MANAGEMENT Lt Col Roshni Varaden SANDF](https://reader035.vdocuments.mx/reader035/viewer/2022081507/551c3dd755034693488b496c/html5/thumbnails/8.jpg)
OBJECTIVES OF HAZARDOUS WASTE MANAGEMENT
• To ensure the correct identification and classification of a hazardous waste
• To prevent hazardous waste entering the environment illegally.
• To implement “cradle-to-grave” principles by means of planned waste management strategies
• To manage hazardous waste until it is safely disposed of, by setting minimum requirements at crucial points in its life cycle

CURRENT SITUATION IN THE RSA
• Material Safety Data Sheets
• Composition of Hazardous Waste
• Chemical Reactions
• Laboratory Fees and Specialists
• Understanding the Minimum Requirements
