Aim: The purpose of this article is to analyze subjective self-evaluation of thermal and respiratory discomfort experienced by workers in the foundry industry. Materials and Methods: One hundred and sixty-one workers aged 18–55 years participated in this study. Discomfort due to high temperatures, hot work, skin rashes, cramps, fatigue, weakness, respiratory problems, and inhalation was subjectively evaluated by the questionnaire survey. The questionnaire is validated, and Cronbach's alpha test and Kaiser–Meyer–Olkin's test are applied to ensure data reliability and adequacy. Results: The results indicated that the highest and lowest percentage of workers experiencing at least one discomfort is 86% and 4%, respectively. Furthermore, 11 out of 19 discomfort factors scored above the average thermal and respiratory discomfort score of 2.5 on the scale of 5. Conclusion: According to this study outcome, more exploration is needed on the relationship among thermal and respiratory discomfort and its effect on the workers in the foundry environment.
