Abstract

There were much study reported that the operational work of spray painting process involves the use of hazardous and highly toxic chemical such as paint and solvent. Hence, the issue become a conflict that concern not only about the occupational safety and health of the workers but also on protecting the environment as well. In a Small and medium (SME) scale spray painting process, therefore, proper safety and health risk management with an efficient engineering control such as ventilation system must be provided for human health. In this study, Hazards Identification, Risk Assessment and Risk Control (HIRARC) method with chemical monitoring was implemented and three suggested CFD based modelling of ventilation system have been analysed in a paint spray booth of a SME scale spray painting process. Based on HIRARC, the overall risk level at the selected spray painting working area can be classified to be at MEDIUM level due to lack of awareness among workers on practicing safe working procedures in workplaces. Based on chemical monitoring analysis, Toluene chemical exposure concentration was high while concentration of Xylene and Paraffin was measured lower than Permissible Exposure Limits (PEL) of USECHH. For CFD based modelling of ventilation system, the inclusion of ventilation system has been shown to improve the indoor air velocity with variation of 0.3 – 1 m/s and reduced chemical concentration in the working area. The result shows that careful design of work space is needed to maintain allowable concentration, which may depend on the position of inlet and outlet. Sufficient exhaust flow rate and inlet velocity also influences the effectiveness of ventilation system.
