  1. Metalworking Fluids

  2. Session Objectives • You will be able to: • Recognize signs of unsafe fluid • Identify metalworking fluid hazards • Use engineering controls effectively • Take all other necessary precautions to protect health and safety

  3. What You Need to Know • Metalworking fluid hazards • Exposure control measures • Safe use procedures • Required PPE • Personal hygiene • Fungi control • Fluid change

  4. Types of Metalworking Fluids • Straight oil • Soluble oil

  5. Types of Metalworking Fluids (cont.) • Semisynthetic • Synthetic

  6. Signs of Unsafe Fluid • Low sump level • Abnormal fluid appearance • Foul smell

  7. Signs of Unsafe Fluid (cont.) • Floating matter • Tramp oil • Excessive foam • Dirty machines or trenches

  8. Signs of Unsafe Fluid (cont.) • Skin irritation • Respiratory irritation • Other fluid-related problems

  9. Labels and MSDSs • Identity of chemical and manufacturer • Hazard warnings • Physical characteristics • Health effects • Safe handling procedures • Emergency response

  10. Health Effects—Skin • Contact dermatitis • Irritant dermatitis • Allergic dermatitis

  11. Health Effects—Skin (cont.) • Causes of dermatitis • Acne-like disorders

  12. Health Effects— Respiratory • Irritation of lungs, throat, and nose • Symptoms • Asthma

  13. Health Effects— Respiratory (cont.) • Chronic bronchitis • Hypersensitivity pneumonitis • Other factors

  14. Control Misting • Use low-pressure flow • Use mist suppressants • Interrupt or reduce flow when practical • Fix leaks • Avoid compressed air to dry parts

  15. Isolation • Mechanical parts handling • Machine enclosures • Splash guarding • Isolation booths

  16. Exhaust Ventilation • Local exhaust ventilation • Enclosure exhaust hood • Exterior exhaust hood • General ventilation

  17. Exhaust Hoods • Close capture enclosure • Total or complete enclosure • Tunnel enclosure • Push-pull ventilation Image Credit: Laboratory Design and Supply

  18. Exhaust Hoods (cont.) • Side-draft hood • Canopy hood • Downdraft hood

  19. Inspection and Maintenance • Fluid filtration systems • Fluid delivery systems • Ventilation systems

  20. Inspection and Maintenance (cont.) • Fluid chemistry • Enclosures and splash guards

  21. Health Effects and Control Measures • Do you understand the information presented in the previous slides?

  22. Fluid Management Program • Responsibility for fluid systems • Responsibility for adding materials • Fluid testing procedures • Tracking data • Employee participation • Training program

  23. Safe Use Procedures • Minimize exposure to fluids • Recognize unsafe fluids • Know how to add fluid to a machine • Recognize ventilation problems • Know how to get something fixed

  24. Controlling Fungi Growth • Clean system before adding new fluid • Fungi grows more rapidly in some situations • Maintain fluid at proper concentration • Make sure water used for mixtures is pure

  25. Controlling Fungi Growth (cont.) • Add biocides • Remove metal chips and fines

  26. Controlling Fungi Growth (cont.) • Remove tramp oil • Practice good housekeeping

  27. Fluid Change • Add cleaner with biocide • Remove old fluid, chips, and swarf • Circulate cleaning solution • Change filters • Refill with fresh fluid

  28. Housekeeping • Clean floors, equipment, and work area • Wear protective clothing when cleaning and use proper cleaning equipment • Clean up spills immediately • Dispose of waste and contaminated items properly

  29. Personal Hygiene • Minimize contact • Clean skin with soap and water • Wear clean work clothes for each shift • Change contaminated work clothes • Keep food, beverages, and tobacco out of work areas • Use barrier and moisturizing lotions

  30. PPE • Hazard assessment • Chemical-resistant gloves • Protective clothing

  31. PPE (cont.) • Eye and face protection • Goggles • Face shields • Safety glasses with side shields • Foot protection

  32. Respirators • Engineering and administrative controls • PEL = 5 mg/m3 for mineral oil mist • N-, R-, or P-series filtering facepiece

  33. Safe Work Practices • Do you understand the information presented in the previous slides?

  34. Exposure Assessment • Qualitative assessment • Personal air sampling • Area air sampling • Source air sampling

  35. Medical Monitoring • Early diagnosis is important • Program includes health review and medical exam • Periodic health evaluations • Symptoms to monitor • Report possible symptoms right away

  36. Key Points to Remember • Know the signs of unsafe metalworking fluids • Report symptoms of skin or respiratory problems • Follow safe work practices • Practice good hygiene and safe housekeeping • Wear required PPE • Monitor and control fungal growth
