RISKS CAUSED BY OCCUPATIONAL EXPOSURE TO PAINTS AND LACQUERS USED IN CIVIL CONSTRUCTIONS

1. RISKS CAUSED BY OCCUPATIONAL EXPOSURE TO PAINTS AND LACQUERS USED IN CIVIL CONSTRUCTIONS Ph.D. Eng. Tamara MORARIU, labour inspector Ph.D. Eng. Gelu CONSTANTIN, labour inspector Labour Inspection, Bucharest

2. PANTED CONSTRUCTION MATERIALS Wood Plastered surfaces Wood floor, concrete floor Fibre board, asbestos cement Ceramic tile Metal

3. Paint Composition by Volume

4. Rezins = polimers: • Natural (plant oils, resins) • Or synthetic (acrylics, polyesters, vinyls, cellulosics, epoxies, etc.)

5. Pigments • Inorganic Ex. Cr2O3 (O, T, cc1), CdS (T, cc3), PbCrO4 (cc3, rc1 and 3) • Organic Ex. Azo dyestuffs (Xi), phtalocyanines componds (Xi)

6. Extenders • carbonates (chalk, dolomite); • sulphates (barium, calcium); • silicates (kaolin, micelle); • oxides şi hidroxides (silicon, aluminium, magnezium).

7. Solvents • water • organic • Petroleum hydrocarbon • Chlorinated hydrocarbon • Oxygenated solvents • terpenes

8. Drying of Emulsion Waterborne Paint

9. Coalescence agent and cosolvents • hidrocarbonsor glycols • naphta solvent (carcinogenic 2nd category) • ethylene glycol acetate (carcinogenic 2nd category) • methylene glycol acetate(carcinogenic 2nd category)

10. Aditive Categories • Antiblok agents • Storage stabilizers • Curing agents • Gloss modifiers • UV stabilizers • Antimicrobial agents • Defoamers

11. Paint Application • Brushing • Rolling • Compressed air spray painting • Airless spray painting

12. Riscuri

13. Restrictions • OLE – Annex 31 la GNLP/2002 • Interdictions– Annex 34 la GNLP/2002 • Trading – Annex 2 la HG 347/2002

14. Firerisk • p.i.  21oC -very inflammable paints • 21oC < p.i.  55oC - inflammable paints • p.i. > 55oC –uninflammable paints but combustible

15. Hazards in constructions • Hazardous chemical substances • Manual handling • Ignition sources • Working at heights • Spray painting plant • Noise • The workplace environment • Confined spaces

16. Occupational illnesses • Occupational asthma • Contact dermatitis • Lung cancer • Damage to the reproductive system • Kidney or lived damage

17. Short term affects • irritant contact dermatitis • burns to the skin or eyes • vomiting and diarrhea • irritating to the nose, throat and lungs • headaches, dizziness, nausea, fatigue

18. Hazards identification Have the measures eliminated or reduced the risks? Have the measures induced new hazards? Is the management system working properly? Could the way it is done be improved? Risks assessment Measures for reducingthe risks Review the measures The main steps of the hazardous chemicals management

19. Hazard identification When: • Introducing a new plant • Using the same produce in different place • Using a new painting plant or a new plant • If new information becomes available

20. Hazard identification Is assisted by: • Paints and equipment manufacturers’ instructions and advices; • A walk through inspection of plant in the workplace and discussion with employers; • Examination of injury, illness or incidents records and health surveillance records.

21. Hazard identificationLabel

22. Hazard identification Safety data sheet • Identification of the substance/preparation and of the company/ undertaking • Composition/ information on ingredients • Hazards identification • First-aid measures • Fire-fighting measures • Accidental release measures • Handling and storage • Exposures control/ personal protection • Physical and chemical properties • Stability and reacting • Toxicological information • Ecological information • Disposal consideration • Transport information • Regulatory information • Other information

23. Work place inspection • Static electricity charges • Incorrectly stored flammable materials • Damaged electrical equipment • Ineffective lighting • Working at heights • Temperature • The lack of first aid • Pour cleanliness

24. Reduced and control the risk measures • Elimination of hazards • Substitution with safer alternatives • Isolation of the dangerous processes • Engineering controls • Administrative controls • Use of PPE

25. Isolation • Physical barriers • Restricted entry of unprotected persons • Removal of hazardous substances • Removal of stored wasted • Removal of electrical and ignitionsources

26. Reviewing the control measures • reexaminarea managementului agenţilor chimici periculoşi • O procedure should include: • Frequency of servicing • Who is responsible • How any defects will be corrected • Performance testing and evolution standards • Records of servicing

27. Conclusions • High diversity of construction materials • Protective and/ or decorative painting • Paints containing hazardous chemical substances • Using of water-paints avoid only the risks caused by organic solvents • Brushing or rolling painting involve less risk than spraying painting • Air less spraying painting presents less risk than classic spraying • Chemical risk assessment is necessary for painting operation
