5 Chemical Risk Assessment (Health Hazard Prevention) Bara Chemical Co., Ltd. To maintain the good hygienic of the production staffs

6 Introduction Since September 2012 the Bara Chemical has been certified OHSAS (Occupational Health and Safety Management System), risk management was based on general prevention not specific for hazardous prevention. JISHA s Chemical Risk Assessment Method for Health Hazard Prevention which was introduced to Thailand by HIDA (The Overseas Human Resources and Industry Development Association) and JCIA (Japan Chemical Industry Association) started to implement in Bara Chemical process.

7 What s JISHA's Chemicals RA Program Guide (Health Hazard Prevention) The Japan Industrial Safety and Health Association (JISHA) issued a manual entitled JISHA's Chemical RA Program Guide (Health Hazard Prevention) for the investigate of the hazardous nature of chemical substances). Steps 1 to 4, 9, and 10 of this manual are similar to those specified for standard risk assessment. Steps 5 to 8 are specific to the risk assessment of chemical substances, and contain consideration of hazard evaluation and measures for the prevention of exposure to hazardous chemical substances.

8 JISHA's Chemicals RA Program Guide ; Risk Assessment Flow Chart Step 1: Assign the risk assessor Step 2: Divide manufacturing/handling processes /workplaces into units to implement RA RA goals, sites, and scope Step 3: Make an inventory of chemicals used. Obtain info. on workplaces/processes Identify chemicals manufactured/handled Step 4: Identify workers engaged in the RA target workplaces Identify target workers Step 5: Gather and evaluate the hazard data, etc. (Hazard assessment) - Identify the hazard data (GHS classifications, OELs: Occupational Exposure Limits, BEI, etc.) - Identify the hazard level (HL) Step 6: Gather and evaluate the exposure data. (Exposure assessment) Identify the exposure level Step 7: Risk characterization Risk Level (RL) V = Intolerable risk Risk Level (RL) IV = High risk Risk Level (RL) III = Medium risk Identify the Risk Level (RL) II = Allowable risk risk level (RL) Risk Level (RL) I = Minor risk Risk Level (RL) S = Risk to eyes and skin Step 8: Develop the Risk control measures to prevent/reduce exposure Risk-level-relevant risk control measures Step 9: Identify RMMs*, implement them, and document the outcomes *) RMMs: Risk Management Measures Step 10: Reassessment PDCA cycle (plan-do-check-act cycle)

9 Step 5: Gather and evaluate the hazard data, etc. (Hazard assessment) Hazard assessment level (HL) must be considered the impact of carcinogenicity that classified in category 1A, 1B, 2

10 Step 6-7: Exposure Assessment and Risk Characterization Measured data available? Yes Yes Yes No STEP 6 Option 1 Av : Working Environment data. Option 2 Av : Personal sampler data. Option 3 Av : Biological monitoring data. Option 4 No data Available. Working Environment concentration Level (WL) & Working Time Level (FL) Estimated Working Environment concentration Level (EWL) & Working Time Level (FL) Exposure Level : EL 1 Exposure Level : EL 2 Exposure Level : EL 3 Exposure Level : EL 4 STEP 7 HL from STEP 5 (Table1)Risk characterization table for EL1, EL2, EL3 HL EL EL HL V V IV III II 5 V IV III III II 4 IV IV III II II 3 IV III III II I 2 IV III III II I 1 Risk Level (RL) V Risk Level (RL) IV Risk Level (RL) III Risk Level (RL) II Risk Level (RL) I Risk Level (RL) S (Table2)Risk characterization table for EL4 5 4 = Intolerable risk = High risk = Medium risk = Allowable risk = Minor risk = Risk to eyes and skin V V IV IV III V IV IV III III IV IV III III II IV III III II II IV III III II I

12 Manufacturing Process for Chemical Risk Assessment Manufacturing process of Melamine Resin - Material - a - Material - b - Material - c - Material - d - Material - e Reflux & Vacuum condensation Cycle time of 1 Batch size Working time Break = 12 hrs/shift/operator = 3 hrs/shift/operator Hazard Data Formaldehyde (ACGIH) Threshold Limit Value (TLV) (2007) = 0.37 mg/m 3

13 Manufacturing Process for Chemical Risk Assessment FF = mg/m 3 FF < mg/m 3

14 Inventory of chemical used and prioritization by GHS Melamine Resin: Carcinogenicity 3 Formaldehyde vapor: Carcinogenicity 1A

15 Hazard Assessment (HL) Refer to JISHA s Guide: Table 1-1 Hazard Level Chemical GHS HL Component Classification (Hazard Level) Melamine Resin Formaldehyde vapor Carcinogenicity 1A Carcinogenicity 1A 5 5

19 Workplace control measures Although, even if the control system and the measuring chemicals in the atmosphere are not over than standard, the PPE is still necessary to minimize the effect to the operator.

20 Standard, Training and Health check investigation 1. Educate the operators about Health Hazards of formaldehyde exposure. 2. Provide an appropriate personal protective equipment (PPE). Ensure that the staffs always use PPE such as impervious clothing, gloves, aprons, and chemical splash goggles to prevent skin and eye contact with formaldehyde. 3. Conduct annual medical check up and report abnormalities immediately
