  1. Working Safely With Corrosives

  2. Session Objectives • You will be able to: • Identify corrosive hazards • Find hazard and protection information • Select appropriate PPE • Store, handle, and dispense corrosives safely • Respond effectively to emergencies • Dispose of corrosive wastes properly

  3. What Is a Corrosive? • Can be solid, liquid, or gas • Causes irreparable harm to living tissue • Will damage materials on contact

  4. Types of Corrosives • Acids • Bases, caustics, or alkalis • Dehydrating agents • Halogens and halogen salts

  5. Corrosive Hazards • Attack skin, eyes, and tissue • Attack other materials • Contribute to fire hazards • Generate hydrogen gas • Create heat • Toxic when breathed

  6. Warning Signs and Labels • Warning signs • DOT label • HMIS® labels • NFPA labels • Pay attention to signs and read labels

  7. MSDS • Identity of corrosive • Exposure limits • Reactivity, fire, and explosion • Health hazards and symptoms of exposure • PPE and first aid • Storage and spills

  8. First Aid • Eyes—flush with water • Skin—wash with water and remove clothing • Inhalation—move to fresh air • Swallowing— medical assistance

  9. Corrosives: True or False? Contact with corrosives can burn your skin and eyes. Corrosives are always liquids. If you get corrosives on your skin or in your eyes, you should move into fresh air. Corrosives contribute to fire hazards. The best source of information about corrosives is a warning sign.

  10. Corrosive Hazards • Do you understand: • About the types of corrosives and corrosive hazards? • The importance of warning signs, MSDSs, and labels? • What the proper first-aid procedures would be if you are exposed to a corrosive?

  11. Engineering Controls • Use safer materials • Reduce operations that disperse corrosives • Minimize potential leak points • Transfer through hoses or pipes

  12. Engineering Controls (cont.) • Enclose corrosive operations • Use ventilation and exhaust systems • Select compatible materials • Minimize operating pressures and temperatures Image Credit: Laboratory Design & Supply

  13. Ventilation • Removes corrosive vapors and mists • Determined by assessment • Checked with monitoring • System of hoods and ducts • Single exhaust fan

  14. Image Credit:WA Dept of Labor & Industries PPE • Safety glasses or goggles • Face shield • Gloves • Protective clothing • Respiratory protection

  15. PPE (cont.) • Inspect before each use • Dispose of damaged PPE • Replace cartridges or worn parts • Wash it carefully after use • Store PPE safely

  16. Storage • Away from production areas • Corrosion-resistant materials • Spill and leak containment • Well ventilated, cool, and dry

  17. Storage (cont.) • Warning signs • Inspections • Glass containers • Incompatible corrosive stored separately

  18. Emergency Equipment • First-aid kit • Spill-response supplies • Safety showers and eyewash stations • Fire extinguishers Image Credit: Stafford Industrial Supplies, Ltd.

  19. Handling Corrosives • Drum hand trucks • Carboy caddies • Safety bottles • Self-closing portable containers Image Credit: University of Alberta Image Credit: Vestil Manufacturing

  20. Dispensing Corrosives • Reduce vapors, mists, and dusts • Use caution when pouring into containers • Use pumps to transfer from drums • Never pressurize a container or add water to acid • Use scoops for solids • Close containers when done

  21. Good Housekeeping • Clean up drips or spills right away • Properly dispose of unlabeled and contaminated materials • Remove empty containers and old corrosive materials • Ensure containers are properly marked

  22. Personal Hygiene • Wash hands frequently • Remove contaminated clothing • Don’t eat or drink around corrosives • Don’t touch skin, eyes, nose, or mouth with contaminated gloves • Wash thoroughly at the end of your shift and change clothes

  23. Emergency Procedures • Leave the area • Flush eyes/skin with water • Notify others of the spill • Limit access to spill area • Only trained personnel can clean up large spills

  24. Goggles Respirator Chemical-resistant gloves Protectiveclothing Face shield Image credit: OSHA Which PPE Is Required?

  25. Working with Corrosives • Do you understand about: • Engineering controls, PPE, and storage, handling, and dispensing requirements for corrosives? • Good housekeeping, personal hygiene, and emergency equipment and procedures?

  26. Waste Management • Ensure containers are appropriate for waste • Don’t mix corrosive waste with other wastes • Dispose of empty corrosive containers properly • Don’t pour corrosives down sinks or drains

  27. Learn about corrosive hazards • Follow safe storage practices • Use available engineering controls • Wear proper PPE • Follow safe work practices • Know first-aid and emergency procedures
