1. SIMPLIFIED METHODOLOGY FOR ASSESSING THE RISK DUE TO EXPOSURE TO HAZARDOUS CHEMICAL AGENTS AND RESULTS OF STUDY İlknur ÇAKAR OHS Expert Chemical Engineer, MSc 27 MAY 2010, ANKARA Ankara

2. OUTLINE • INTRODUCTION • SIMPLIFIED RISK ASSESSMENT METHOD FOR CHEMICAL AGENTS • WORKPLACE STUDY • RESULTS OF STUDY • CONCLUSION

3. INTRODUCTION RISK ASSESSMENT 89/391/EC Framework Directive 98/24/ECProtection of the health andsafety of workers from the risks related tochemical agents at work • “the employer shall first determine whether any hazardous chemical agents are present at the workplace. If so, he shall then assess any risk to the safety and health of workers arising from the presence of those chemical agents,

4. INTRODUCTION • The variables generally used; • intrinsic hazards of chemical agents • frequency/duration of exposure • quantity of chemical agents used or present • volatility or dust generation of chemicals • method of use

5. Table1. Risks arising from thepresence of hazardous chemical agents

6. Risk Assessment Methods Table 2. Methods for assessing the risks due to the presence of hazardous chemical agents in the workplace

7. When are simplified models useful? • Initial risk assessment • Identification of slight risk • As a documental help when, in the view of the hygienist, the scenary is acceptable • There is no occupational exposure limit established • Possible use by SME (small and medium enterprises)

8. Identification of Chemical Agents Working Conditions Hazard Risk Assessments (Simplified) Risk Assessments (Detailed) Preventive measures :priorisation-planification -implementation Review Risk Assessments for Chemicals

9. Assessment of the risk of exposure by inhalation Exposure Hazard Risk • F-Chem properties • Toxicol. properties • Physical form • - label • - MSDS • - Limit Value • - others • Concentration • volatility or • dustiness • form of use • quantity used • control measures • Time • duration • frequency

10. Simplified assessment: • No airborne measurements • These methodologies do not constitute an alternative to an detailed risk assessments • They do just first diagnosis of the situation

11. Volatility or dustiness Hazard Risk level Amount of substance Control measures COSHH Essential (R phrases) +

12. Chemical hazard (according to R phrases)

13. 300 Medium 250 Boiling Temperature, ºC 200 150 High 100 50 0 20 50 80 110 140 Process Temperature, ºC Volatility Low

14. Dustiness Low: Pellets and similar. Little dust is seen during use • Medium: crystalline, granular solids • When used, dust is seen but settles out quickly High: Fine, light powders There are dust clouds that can remain for minutes

15. Amount of substance used in the operation • Small: Grams or mililitres • Medium:Kilograms or litres • Large: Tons or cubic metres

18. Risk bands RB1: Can be controlled with: GeneralVentilation RB2: Can be controlled with: Partial enclosure and local exhaust ventilation RB3: Can be controlled with: Total enclosure RB4: An expert in industrial hygiene is needed

19. Workplace Study • In this study, the industrial exposure to the chemicals that occurred in small-sized furnituremanufacturing firms have been analyzed. We’ve had interviews with workersin 15 workplaces

20. Workplaces

21. Results • % 11 below 20 years old • % 17 over 45 years old. • Average of the workers’ age : 34, • Average of the working years : 18 years. • Smoking % 59 • Use of alcohol % 22
