Presentation Transcript

  1. Chemical Spill Procedures Environmental Health and Safety Office

  2. Chemical Spills • Unintentional and uncontrolled release of a chemical/hazardous material into the environment • Chemicals • Laboratory spaces • Physical Plant/Caretaking • Two main categories: • Major spills • Minor spills

  3. Approaching Chemical Spill Situations • If a spill occurs • Do not panic • Determine the identity of the spilled substance • Refer to the Material Safety Data Sheet (MSDS) • Assess the situation • Cordon off the area • Determine the severity of the spill • Major vs. minor

  4. Major Spills • Injuries sustained that require medical attention • Poses an immediate danger to life and health • Potential for fire or explosion • Quantity • Properties or hazards of the spilled material are unknown • Major spills require an external emergency response for clean-up

  5. Major Spills - Response • Evacuate the area • If safe • Attend to injured persons • Shut of possible ignition sources • Try to control spread of spill • Notify your supervisor • Who to contact • During business hours: • Locate Chief Fire Warden and contact EHSO (474-6633) • After business hours: • Security services (555 on red phones, or 474-9341)

  6. Major Spills - Aftermath • Incident investigation • Direct supervisor • Local Area Safety and Health Committee (LASHC) • EHSO

  7. Minor Spills • Clean up • Responsibility of those accountable for the spill • EHSO will provide technical advice or onsite assistance when requested • Only laboratory staff have the appropriate training for cleaning a laboratory spill

  8. Minor Spills – Response • Look after contaminated people • Restrict the area with appropriate signage • Control spread of spill • Refer to the MSDS • Follow established safe work procedures • Contact • During business hours: EHSO (474-6633) • After business hours: Security services (555 or 474-9341)

  9. Hazardous Waste • Adsorbent materials • Utilized to clean the spill • Hazardous Waste Program • EHSO • Proper disposal

  10. Entering Laboratory Spaces

  11. Assessing Laboratory Spaces • WHIP

  12. Assessing Laboratory Spaces • WHIP • Personal Protective Equipment (PPE) • Safety glasses • Laboratory gloves • Decommissioning • Responsibility of the lab • General cleanliness • Removal of chemicals and equipment • Experiments • You have the right to refuse work if the area is not properly decommissioned

  13. Unexpected Substances • Locate the source • Unknown substance • Contact laboratory personnel • EHSO

  14. Accidental Chemical Exposure • Determine the nature of the chemical • Refer to the MSDS • Locate the emergency eyewash, shower stations, and sink • Notify appropriate personnel • Direct supervisor • During business hours: Appropriate lab personnel, and EHSO (474-6633) • After business hours: Security services (555 or 474-9341), and 911
