Module 5: Environmental and Health Considerations
5.1 Preventing Pollution and Environmental Impact
Effective waste management must minimize ecological damage through proactive pollution control measures.
Key Prevention Strategies:
Leachate Management:
Install composite liners (clay + HDPE) in landfills to block groundwater contamination.
Treat collected leachate via reverse osmosis or biological reactors before discharge.
Air Quality Protection:
Landfill gas capture systems (methane flaring or energy conversion).
Dust suppression techniques (water sprays, wind barriers) at transfer stations.
Stormwater Controls:
Impervious paving and silt fences at waste sites to prevent runoff pollution.
Oil-water separators in vehicle wash areas.
Sustainable Material Recovery:
Increase recycling rates to reduce virgin resource extraction impacts.
Lifecycle assessments to compare disposal methods' environmental footprints.
Regulatory Benchmarks:
EPA's Clean Air Act standards for PM2.5 emissions from waste facilities.
EU Landfill Directive's 65% organic waste diversion target by 2035.
5.2 Occupational Health Risks and Mitigation
Waste workers face multiple hazards requiring systematic risk controls.
Major Hazards & Protections:
Health Surveillance Programs:
Annual lung function tests for workers exposed to particulates.
Heat stress monitoring during summer collection routes.
Training Requirements:
OSHA 29 CFR 1910.120 for waste site safety protocols.
WHMIS/GHS labeling comprehension for chemical exposure risks.
5.3 Emergency Response for Accidental Spills or Releases
Preparedness is critical for containing unexpected waste releases that could harm health or the environment.
Response Protocol Steps:
Immediate Containment:
Deploy absorbent berms for liquid spills (e.g., food processing waste).
Cover exposed waste piles with tarps during heavy rain to prevent leachate.
Notification Procedures:
Internal alerts to site supervisors per company SOPs.
Regulatory reporting if spill reaches waterways (EPA's NRC: 1-800-424-8802).
Cleanup & Decontamination:
Biohazard kits for organic waste incidents.
Professional remediation for persistent contaminants (e.g., asbestos in C&D waste).
Equipment Readiness:
Spill kits stocked with:
Absorbent pads and granular materials.
pH neutralizers for accidental acid/base mixing.
Eyewash stations near handling areas.
Drill Frequency:
Quarterly spill simulations with emergency responders.
Annual refreshers on evacuation routes and PPE donning.
Next Steps: Module 6 will detail Legal Compliance and Reporting, including permit acquisition and audit preparation.
