Presentation Transcript

  1. Solvents

  2. Some common solvents • Charcoal lighter fluid, • Windshield washer fluid, • Paint, • Household cleaners, and even • Water! 1a

  3. Use of solvents • Cleaning • Degreasing • Removing paint, ink, or other coatings 1b

  4. Use of solvents • Producing adhesives, paints, inks, coatings, varnishes, and other sealers • Solvents we work with 1c

  5. How to recognize solvents • Usually liquid • Many are colorless • Most have a strong odor • Some evaporate quickly 2a

  6. How to recognize solvents • Always check the container’s label 2b

  7. Chemistry of solvents • Solvents are used to dissolve something else • Like dissolves like • How electron are distributed is called polarity 3a

  8. Chemistry of solvents • Polar solvents: • Water • Ketones • Alcohols • Non-polar solvents: • Oils • Petroleum distillates • Many chlorinated solvents 3b

  9. Chemistry of solvents • Always use the solvent specified for the job • Why we use certain solvents 3c

  10. Health hazards • Routes of entry include: • Breathing the vapors, • Direct contact, and • Ingestion if you are eating or drinking while using the solvents. 4a

  11. Health hazards: Acute effects • Dizziness • Nausea • Irritation • Dryness • Itching • Dermatitis 4b

  12. Health hazards: Chronic effects • Chronic diseases typically target: • Skin, • Liver, • Kidneys, • Circulatory system, • Reproductive system, and • Nervous system. 4c

  13. Health hazards • Check the MSDS • Health hazards of the solvents we use 4d

  14. Physical hazards • Combustible • Flammable • Check the MSDS • Physical hazards of the solvents we use 5

  15. Engineering controls that reduce exposures • Ventilation • Automated chemical transfer equipment • Engineering controls we use 6

  16. Personal protective equipment (PPE) • See solvent’s MSDS for PPE recommendations • Employer selects appropriate PPE • Types of PPE we use 7

  17. Safe work procedures • See solvent’s MSDS for safe handling information • Take appropriate fire prevention precautions • Use only the amount needed 8a

  18. Safe work procedures • Dispense carefully to avoid spills • Be cautious about skin contact • Follow all job-specific work procedures 8b

  19. Safe storage procedures • See solvent’s MSDS for safe storage information • Solvents may need to be stored separately from other materials • Storage areas should be well ventilated 9a

  20. Safe storage procedures • Rough handling can lead to dangerous leaks • Inspect containers for damage prior to use • Report suspected damage, contamination, or leaks 9b

  21. Proper clean-up and disposal • Emergency releases should be handled by a specially trained Hazmat team • Waste solvents need to be collected in proper containers 10

  22. First aid and emergency procedures • Refer to the MSDS for first aid and emergency information • Always follow our company’s specific procedures for emergency response and first aid 11
