Simulation of Exposure to Metal Fumes in The Smaw Welding Process Using IH MOD 2.0: Occupational Health and Safety Assessment

Abstract

Objective: This study aims to investigate the potential of simulation using IH Mod 2.0 as an accessible and effective tool to predict exposure to metal fumes in the SMAW welding process. Theoretical Framework: Metal fumes, as pollutants generated in welding processes, can harm human health. Methods for anticipating health risks to workers stand out, providing a solid basis for promoting a safer occupational environment. Method: The methodology adopted for this research comprises simulation using the IH Mod 2.0 tool to calculate the concentration of Cr, Mn, and Ni pollutants during welding for two types of electrodes in environments with and without ventilation. Concentration estimates were calculated based on data provided by the manufacturer. Results and Discussion: The results revealed minimal differences between the values predicted and calculated by IH Mod 2.0, validating the tool’s capability to accurately simulate fume emissions in the SMAW welding process, even though the model does not account for the different risks associated with each contaminant. Research Implications: This research's practical and theoretical implications are discussed, providing insights into how the results can be applied or influence practices in occupational health and safety. These implications could encompass metal fume exposure from welding activities in the industrial and construction sectors. Originality/Value: This study contributes to the literature by simulating welding risks in an economical and efficient way, enabling preventive analysis and strategic decision-making that prioritizes workers' health and safety.
