Incidence of Silicosis among Quarry’s Workers in Chonburi Province
The objective of this study is to review the incident of Silicosis among workers in 27 quarries of Chonburi who had had medical check-up at Chonburi hospital between 2013 and 2018. Which number of workers examined were 1,056, 1,201, 1,262, 1,134, 1,348 and 1,128 respectively. The objectives are including review spirometry, smoking behavior, and using personal protective equipment. This descriptive study used data from Chonburi hospital and was analyzed by the SPSS 24. The study shows decreasing incidence of silicosis (defined by the ILO classification as profusion 1/0 and more) as 9.9%, 17.4%, 8.1%, 8.8%, 6.0%, and 5.7% respectively. In contrast, incidence was still higher than United states of America’s and China’s. Most workers with Silicosis work in milling, driving, and office. Proportion of workers with abnormal spirometry are 19.3, 20.0, 23.1, 25.7, 27.8, and 23.6 respectively. Using N95 mask for prevention of crystalline silica is increasing from 16.5% to 30.4% in 2017 and 2018. Smoking is consecutively decrease from 34.6, 30.7, 33.4, 28.3, and 27.5 in 2014 to 2018. In conclusion, incidence of Silicosis among quarry’s workers in Chonburi province consecutively declined which reflects effectiveness of health promotion and prevention from collaboration amongst quarry association and Chonburi hospital, which are engineering control, administrative control, and personal protective equipment. Using N95 is increasing. Furthermore, decreasing number of smokers also reflects effective and efficient smoking cessation program. Nevertheless, Silicosis remains crucial problem because of incurability and carcinogenicity. Hence more policies for prevention and health promotion will lower incidence of Silicosis.
