  2. LEAD EXPOSURE IN AUTOBODY SHOPS • MA Division of Occupational Safety (DOS) inspections (surface prep. & new paint) • OSHA inspections • Journal articles • MSDSs

  3. OTHER CHEMICALS • Chromium • Isocyanates • Methylene Chloride • Other?

  4. SURVEY OF MASSACHUSETTS VOCATIONAL HIGH SCHOOL AUTOBODY PROGRAMSRichard RabinMassachusetts Division of Occupational Safetyin cooperationwith theMassachusetts Department of EducationSURVEY OF MASSACHUSETTS VOCATIONAL HIGH SCHOOL AUTOBODY PROGRAMSRichard RabinMassachusetts Division of Occupational Safetyin cooperationwith theMassachusetts Department of Education

  5. PURPOSE OF SURVEY • Learn work practices, controls in school autobody programs • Stimulate awareness of hazards • Catalyst for requesting DOS consultation

  6. GENERAL SURVEY BACKGROUND List of 41 schools from MA Dept. of Education 3 schools do not have autobody program 37/38 programs returned questionnaire

  7. GENERAL • NATEF-approved 86% • Frame work 36% • Vehicles/week .4 - 10

  8. EQUIPMENT • Spray painting booth/room 100% -- Down-draft ventilation 81% -- make-up air 89% -- explosion-proof exhaust fan 97% Paint priming outside booth 16%

  9. SANDING, GRINDING, WELDING • Use sanders w/ vacuum 64% • Welding – exhaust system 43% • Sanding/grinding – tarps 39%

  10. PAINTS AND SURFACE PREPARATION • Water-borne basecoasts 8% • Chromate paints 29% • Lead paints 15% • Methylene chloride 6%

  11. WORK PRACTICES • Right-to-Know • MSDSs 100% • Container labeling 100% • Training (teacher) in past yr. 69% Student training 100%

  12. WORK PRACTICES Respirators program 100% air-supplied respirator (spray paint) 78% air-purifying respirator (sanding) 34% Showers/change room Present 26% Required use 21% HEPA vacuums for clean-up 18%

  13. RECOMMENDATIONS - EQUIPMENT • Spray painting booth/room: down-draft ventilation Mechanical supply of tempered, outside air • NFPA Class I, Division 1 location, including explosion-proof/intrinsically safe electrical equipment

  14. RECOMMENDATIONS - EQUIPMENT • Air velocity in a spray booth 100 fpm • Spray painting distance from potential ignition source 20 ft.

  15. RECOMMENDATIONS – SANDING, GRINDING, WELDING • Vacuum sanders with a HEPA attachment • Local exhaust ventilation for welding • Tarps or other kinds of enclosures

  16. RECOMMENDATIONS – PAINTING, SURFACE PREP. • Water-borne paints • Avoid lead, chromium • Avoid methylene chloride

  17. RECOMMENDATIONS – WORK PRACTICES • Respirator program • Maintenance • Cleaning • Storage • Fit-testing • Medical screening • Training on use, selection, limitations
