Waste management Flashcards
Analyze the relationship between waste segregation practices and the prevention of chemical reactions in hazardous waste storage.
Segregation of hazardous waste based on compatibility prevents chemical reactions by ensuring incompatible substances (e.g., acids and bases) are stored separately. This minimizes risks such as fires, explosions, or the generation of toxic substances.
How do secondary containment systems contribute to environmental protection in waste storage facilities?
Secondary containment systems, such as dikes, berms, or double-walled tanks, act as a barrier to contain leaks or spills from primary storage containers, thus preventing hazardous substances from contaminating soil or water sources.
Examine how Section 34B of the EQA 1974 impacts the export and import of hazardous waste in Malaysia.
Section 34B imposes strict penalties for illegal trafficking of scheduled wastes, including imprisonment and fines. This deters unauthorized handling and ensures compliance with environmental standards for hazardous waste management.
Compare the roles of regulations and orders in enforcing hazardous waste management compliance.
Regulations provide the legal framework and guidelines, such as classification and storage requirements, while orders address specific violations and enforce compliance by mandating corrective actions, such as facility closures.
How does the responsibility of waste generators in proper labeling and documentation support the overall hazardous waste management system?
Proper labeling ensures the identification of waste types and hazards, while documentation enables traceability and accountability throughout the waste management chain, aiding in compliance and environmental protection.
Evaluate the significance of licensed collectors and transporters in the scheduled waste management process.
Licensed collectors and transporters ensure that waste is handled by trained professionals, reducing risks of mishandling, leaks, or spills, and ensuring compliance with DOE regulations.
Analyze the role of safety data sheets (SDS) in the identification of hazardous waste
SDS provides critical information about a material’s properties, hazards, and handling precautions, enabling waste generators to identify and classify hazardous waste accurately.
Why is laboratory testing necessary for certain types of waste, and how does it enhance waste characterization?
Laboratory testing, such as toxicity or reactivity tests, is essential when visual inspection and documentation are insufficient. It provides precise data on waste properties, ensuring accurate classification and proper handling.
Assess how the use of specific storage containers, such as steel drums or IBCs, aligns with the safe handling of different hazardous waste types.
The choice of storage containers depends on waste properties. Steel drums are suitable for flammable liquids, while IBCs accommodate large quantities, ensuring containment and minimizing risks of leakage during transport.
How do “Scheduled Waste Consignment Notes” facilitate safe transportation and disposal of hazardous waste?
These notes document the waste type, origin, quantity, and destination, ensuring proper tracking, accountability, and compliance with legal and safety requirements during transportation.
Analyze the impact of the Environmental Quality (Scheduled Wastes) Regulations 2005 on the practices of waste generators in Malaysia.
The regulations mandate proper waste classification, storage, and record-keeping, compelling waste generators to adopt standardized practices that ensure safe handling and compliance with environmental laws.
How does the Third Schedule of the EQR 2005 help in standardizing hazardous waste labeling across industries?
It ensures uniformity by specifying label dimensions, colors, and hazard symbols, aiding in quick identification and compliance.
Examine the implications of failing to meet the 180-day waste accumulation limit for waste generators.
Non-compliance can lead to legal penalties and increased environmental risks due to prolonged waste storage.
How does the DOE ensure effective enforcement of the Environmental Quality (Scheduled Wastes) Regulations 2005?
Through licensing, audits, inspections, and issuing closure orders for non-compliant facilities.
Analyze the role of consultation with hazardous waste experts in identifying waste characteristics.
Experts provide insights into complex waste types, reducing misclassification risks and ensuring compliance with regulations.
