  1. Safe Chemical Handling

  2. Session Objectives • You will be able to: • Recognize hazards posed by materials • Know how to find safety and health information about hazardous materials • Understand required precautions for safe handling of all materials • Know what to do in an emergency

  3. Regulation of Hazardous Materials • Occupational Safety and Health Administration (OSHA) • Environmental Protection Agency (EPA) • Department of Transportation (DOT) • Occupational Safety and Health Administration (OSHA) • Environmental Protection Agency (EPA) • Department of Transportation (DOT)

  4. OSHA’s Hazard Communication Standard • You have the right to know: • Materials in the workplace • How these materials can be hazardous • How to handle materials safely to protect yourself from hazards

  5. Hazard Classes • Corrosive • Flammable • Toxic • Reactive • Radioactive

  6. Information About Hazardous Materials • Labels • MSDS • Supervisor

  7. Primary ContainerLabel • Identity of the material • Manufacturer contact information • Physical/health hazards • Special handling • PPE recommendations • First aid, fire response,and spill cleanup

  8. SecondaryContainer Labels • Identity of the material • Hazard warnings Note: Secondary containers must be appropriate for the job and material; old milk bottles are not appropriate!

  9. Information Resource: The MSDS • Is a written description of a hazard related to a material • Describes the risks, precautions, and remedies to exposure • Must be readily available to you • Read the MSDS before working with a material!

  10. MSDS (cont.) • Material and manufacturer identity • Hazardous ingredients and exposure levels (PEL or TLV) • Physical and chemical properties • Fire, explosion, and reactivity

  11. MSDS (cont.) • Health hazards: • Routes of entry • Symptoms of exposure • First-aid and emergency information

  12. MSDS (cont.) • Spills and leaks • Safe handling and storage • PPE • Compliance issues

  13. Physical States Of Matter (Materials) • Plasma • Liquid • Solid • Gas • Physical state can affect route of exposure

  14. How Materials Enter Your Body Inhalation Skin absorption and eye contact

  15. How Materials Enter Your Body (cont.) • Ingestion (eatingcontaminated food) • Penetration through a cut, puncture, or injection

  16. Symptoms of Overexposure • Skin or eye irritation • Difficulty breathing • Dizziness • Headache • Nausea and vomiting

  17. Typical Hazardsand Information:Q&A Q. How can any material be hazardous? A. Corrosive, toxic, flammable, reactive, radioactive Q. What is the most complete source of information about a material’s hazards? A. Material safety data sheet (MSDS) Q. What are the primary routes of exposure? A. Inhalation, absorption, ingestion, injection

  18. Typical Hazards And Information • Do you understand: • What hazards are posed by materials you use? • How to find information about materials? • Physical states of materials? • Exposure routes? • Symptoms of overexposure?

  19. General Rules For Handling Materials Safely • Follow all established procedures • Be cautious and plan ahead • Use required PPE • Make sure containers are properly labeled • Always read labels and MSDSs before handling any materials • Use the materials only as intended • Follow all established procedures • Be cautious and plan ahead • Use required PPE • Make sure containers are properly labeled • Always read labels and MSDSs before handling any materials • Use the materials only as intended

  20. General Rules for Handling Materials Safely(cont.) • Never eat or drink while handling • Never smell or taste a material • Know emergency procedures and equipment • Store all materials properly • Keep yourself and your work area clean

  21. Handling Flammable Liquids Safely • Keep containers closed when not in use • Keep away from ignition sources • Avoid contact with incompatible materials • Transfer to approved containers only • Bond and ground containers when transferring flammable liquids • Clean up spills and dispose of waste properly • Keep containers closed when not in use • Keep away from ignition sources • Avoid contact with incompatible materials • Transfer to approved containers only • Bond and ground containers when transferring flammable liquids • Clean up spills and dispose of waste properly

  22. Proper Storage of Flammable Liquids • Store flammable liquids only in approved storage rooms and cabinets • Understand and follow all storage rules • Replace bung caps with drum vents after receiving containers • Ground all drums properly

  23. Handling Incompatible Materials Safely • Consequences of mixing incompatible materials include: • Fire • Explosion • Chemical reactions • Release of heat • Splashing • Degradation of materials

  24. Handling Incompatible Materials Safely (cont.) • Avoid mixing: • Flammables and oxidizers or ignition sources • Acids and cyanides • Strong acids and alkalines • Concentrated acids and water • Organic solvents and corrosives • Corrosives and other reactive materials • Avoid mixing: • Flammables and oxidizers or ignition sources • Acids and cyanides • Strong acids and alkalines • Concentrated acids and water • Organic solvents and corrosives • Corrosives and other reactive materials

  25. Responding to Emergencies • Emergency phone numbers • Spill response • Equipment shutdown procedures • Evacuation routes and assembly areas

  26. Image Credit: Stafford Industrial Supplies, Ltd. What Emergency Personnel Need to Know • Emergency cleanup and disposal procedures • Required PPE • Use of cleanup and emergency equipment • Fire-fighting and first-aid measures

  27. First Aid—Eye Exposure • Don’t rub eyes • Go directly to an eyewash station • Hold eyelids open and flush with water for 15 minutes • Do not contaminate the other eye • Seek immediate medical attention

  28. First Aid—Skin Exposure • Remove clothing and jewelry from affected area • Flush area with water for 15 minutes • Use an emergency shower if necessary • Seek immediate medical attention

  29. First Aid—Inhalation • Get into fresh air • Seek immediate medical attention

  30. First Aid—Ingestion • Check the MSDS for first-aid instructions • Call the poison control center for additional assistance • Induce vomiting only if directed • Get immediate medical attention

  31. Safe Handling Procedures:Make the Safe Choice a. Water Flammables should be kept away from: When transferring flammable liquids, containers must be: If you get chemicals on your skin: Mixing incompatibles could cause: b. Ignition sources a. Locked out b. Bonded and grounded a. Flush with water b. Rub with hand lotion a. An electrical shock b. Fire or explosion

  32. Safe Handling Procedures (cont.) • Do you understand: • General rules for handling hazardous/reactive materials safely? • How to handle flammable materials safely? • How to handle incompatibles? • Emergency procedures? • First aid for chemical emergencies?

  33. Key Points to Remember • Most materials can be hazardous in some way • You can avoid injuries and illness if you know how to safely handle all materials • Always wear required PPE and follow established safety procedures • Know what to do in the event of an emergency involving hazardous/reactive materials
