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 2

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 3

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 4

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) 5

6. Major Spills - Aftermath 6  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 7

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) 8

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