2. Hazardous Communications & Lab Safety • Title 8 CCR, 5194 • Smoking Policy • Chemical Inventory • MSDS’s • Hazard Properties • Labeling • Emergency Response • Hazardous Materials & Waste • Laboratory Practices

3. Title 8 CCR, 5191 & 5194 • (1) This section requires manufacturers or importers to assess the hazards of substances which they produce or import, and all employers to provide information to their employees about the hazardous substances to which they may be exposed, by means of a hazard communication program, labels and other forms of warning, material safety data sheets, and information and training. In addition, this section requires distributors to transmit the required information to employers. You have a right to know!

4. 8 Elements of the IIPP • IIPP Responsibility - University President and RM&S • Compliance – 8CCR3203, safe work practices • Communication –We all communicate about safety • Accident/Exposure Investigation – Prevention • Hazard Identification – On all levels • Hazard Mitigation– Risk assessments • Training – Best practices and regulatory compliance • Documentation– Maintenance and retention of records

5. Campus Non-Smoking Policy • Smoking is allowed only in “Designated areas” • Designated areas • Visible by signage • At or around each university building • Smoking Cops = Peer pressure • Any other locations are against university policy • See the RM&S website for more information on the policy and procedure.

6. Hazardous Materials Label Isopropyl Alcohol X X X X X

7. Physical/Health Hazards • Explosive • Flammable • Combustible liquid/gas • Water reactive • Oxidizer • Organic peroxide • Unstable • Corrosive • Sensitizer • Irritant • Toxic

8. NFPA • Health • Flammability • Reactivity • Special hazard “Radioactive Material” Biohazardous Material

9. NFPA • Health • Flammability • Reactivity • Special hazard

10. Identification of Health Hazard 4 Materials that on very short exposure could cause death or major residual injury 3 Materials that on short exposure could cause serious temporary or residual injury 2 Materials that on intense or continued (not chronic) exposure could cause temporary incapacitation or possible residual injury 1 Materials that on exposure would cause irritation by only minor residual injury 0 No Health Hazard

11. Identification of Flammability Hazard 4 Materials that will rapidly or completely vaporize at atmospheric pressure and normal ambient temperature 3 Liquids and solids that can be ignited under almost all ambient temperature conditions 2 Materials that must be moderately heated or exposed to relatively high ambient temperatures before ignition can occur 1 Materials that must be preheated before ignition can occur 0 No Flammable Properties

12. Identification of Reactivity Hazard 4 Materials that are readily capable of detonation or of explosive decomposition or reaction at normal temperatures 3 Materials that are capable of detonation or explosive reaction but require a strong initiating source 2 Materials that readily undergo violent chemical change at elevated temperatures and pressures or which react violently with water or which may form explosive mixtures with water 1 Materials that are normally stable, but which can become unstable 0 Non Reactive

13. Example - NFPA • Isopropyl Alcohol • Slightly Toxic • Highly Flammable • Not Reactive • No Special Hazard 3 1 0

14. RM&S Preference Labels can be obtained through lab technicians or RM&S

15. MSDS • Material Safety Data Sheets • Available in RM&S office, designated areas in Science Halls and with 3E on demand • Why are they important?

16. Chemical Id Synonyms Hazardous Ingredients PEL, TLV Physical Data Appearance and odor Fire & Explosion Data Flash-point Health Hazards Signs and symptoms Reactivity data Incompatibles Spill Procedures Notify Supervisor Special Protection PPE Special Precautions MSDS Contents

17. Controls • Engineering controls: -hoods, cabinets, safety cans, trays • Work practices: -operating procedures • Personal protective equipment: -safety glasses, lab coats, gloves, no open-toed shoes

18. Personal Protective Equipment • PPE • Gloves • Goggles • Lab Coats • Face Shields • Safety glasses • Coveralls

19. Types of Emergencies • Medical emergency • Fire • Chemical spill • Biohazardous material spill • Radioactive material spill • Bomb threat • Earthquake • Power outage • Flood

20. Emergency Equipment • First-Aid kits • Spill kits • Safety showers • Eyewash stations • Fire extinguishers • Flashlights • Emergency Exits

21. First Aid • Eyewash • Minimum of 15 min • Shower • remove contaminated clothing • 1st Aid Kits • Where is it? • Call 911 Dispatch • or RM&S @ ext. 4502

22. Non-Emergency Medical Care Employees Concentra Medical Center 740 Nordahl Road, Suite 117 San Marcos (760) 432-9000 Mon.- Fri. 8 a.m. – 6 p.m. Students Student Health Services San Marcos Ambulatory Care Center 120 Craven Drive, Suite 102 Ext. 4005 Report all injuries no matter how small.

23. Fire Safety • Prevention • The Fire Triangle • Oxygen, Heat, Fuel • Classification of fuels • Types of extinguishers • Extinguishing a fire • Evacuation

24. Fire Safety • A – combustibles • B – flammable liquids • C – energized equipment • D – flammable metals

25. Fire in the Laboratory P.A.S.S. • Pullthe pin • Aimat base of fire • Squeezethe handle • Sweepside to side • Position yourself between the fire and escape route • Have a back-up • Do not turn your back to the fire • Alert key personnel regarding the incident

26. Fire: Fight or Flight? Evacuate if: • You do not know what is on fire • The fire is spreading rapidly • You do not have the appropriate extinguisher • You might inhale toxic smoke • You cannot maintain an escape route • Your instincts tell you not to fight the fire

29. Fire Happens!!

30. LaboratoryWaste Management

31. Types of Wastes • Chemical/hazardous • Pharmaceuticals • Controlled Substances • Glass • Sharps • Universal wastes • Empty containers

32. Hazardous Waste Determination Is the waste; • Reactive, corrosive, flammable, or toxic? • Specifically listed in the regulations? • Derived from a listed material? • Potentially hazardous to health & the environment? Confirm any non-hazardous waste determination

33. H. Garcia SCI 313 4511 9/12/05 1L L 100 Isopropyl Alcohol X X X X X Labeling Waste • Contents • Composition • Physical hazards • Health hazards • Target organs • Physical state • Generator name, address and phone number • Accumulation start date

34. Hazardous Waste • Inform PI or Tech When waste is 3/4 full • Segregated by Physical state • Liquid, Solid, & Sharps • Segregated by hazard • Chem, Rad, & Bio • Material name • Generator Info • An appropriate hazard warning • Waste declaration • Accumulation start date

35. Radioactive Materials • “Caution Radioactive Materials” • Hazards • Exposure • Internal VS External • Waste • Secured • labeled • Segregated

36. Bio-Hazardous Materials • “Universal Precautions” • Signs - shall be posted at the entrance to work areas. • Prepare “WASTE” • Double bagged (RED) • Generator label • Notify RM&S and Principal Investigator for special handling.

37. Universal Wastes • Fluorescent light bulbs • Alkaline/lead batteries • Computer monitors/CPU’s = E-waste • Thermostats • Tires

38. Waste Disposal Procedures • No sewer discharge • Properly separate wastes • Complete and attach a waste label • Isolate mixed wastes • Place in waste accumulation area

39. How would you respond?

40. Spill Response • Notification • Public safety • Containment • Waste management • Decontamination

41. Minor Spill Response • Inform P.I., co-workers & contact RM&S • Assess situation: Injuries priority • De-energize ignition source • Barricade spill area • Don PPE • Confine/Contain spill area • Waste collection

42. Laboratory Work Practices • Wear the appropriate PPE • Eating, drinking, applying cosmetics is prohibited in labs • Wash your hands after working with hazardous materials • Clean up spills immediately • Keep fume hood sash at the appropriate level • Replace broken or damaged lab equipment • Empty containers are considered trash unless contents are highly toxic

43. Children and pets are not allowed in the laboratories Properly label containers Keep containers closed when not in use Perform routine equipment inspections Provide contact information for continuous operations Do not work alone Laboratory Work Practices (continued)

44. Egress keep isles clear Fire doors keep closed Extensions cords use power strips High storage <18” below sprinklers Emergency Equipment maintenance Shelving >5ft must be braced Utility panels maintain 36” clearance Floor mats ice machines, sinks Housekeeping Cleanliness Work Area Safety/Consultations
