Health Risk Assessment of Workers at the Mining Company PT. HIJ Site in South Kalimantan: An Overview

There are many hazards in the mining sector that have potential risks to the health and well-being of workers. The environment where mining processing takes place can cause health problems such as silicosis, pneumoconiosis, noise-induced hearing loss, musculoskeletal disorders and other health complications that can cause accidents. Identifying the health hazards and their sources in the workplace is required to manage the health risks. Based on MCU data in 2016, the top five diseases, such as dyslipidemia, refraction disorder, BMI > 25, abnormal audiometry, and abnormal liver enzymes were found. This study was conducted to get a comprehensive overview of health risks in the workplace. A cross-sectional design was used to conduct occupational health and safety risk assessments and classify them as health risk in mining, hauling road and port area. This study also considers the MCU results and clinic visits in 2016. Based on hazard identification and risk control (HIRADC) mining, hauling road, and port, there were two categories of risk value: medium and low. From the MCU results, dyslipidemia at 85.9 percent, BMI > 25 at 46.15 percent, refraction disorder at 16.67 percent, abnormal audiometry at 15.38 percent and abnormal liver enzymes at 13.92 percent were found. Based on the clinic visits data in 2016, the five diseases found were the common cold at 14.04 percent, acute pharyngitis at 10.03 percent, rhinitis at 10.32 percent, myalgia and muscle aches at 7.45 percent and coughing at 7.16 percent. From the research results, it can be concluded that the health risk assessment (HRA) has been implemented well, but it only assessed the risk factors of the work environment. Seen in MCU and clinic visits, the illnesses are diagnosed not only from the work environment but also from the patterns of work and lifestyle.
