Introduction: The work process of the Painting Area in a Manufacturing Company can pose a risk to physical and chemical health hazards for workers. Hazard analysis and identification, exposure assessment, and risk assessment are, therefore, needed to protect the health of workers from these health hazards, which can later be used as a basis to determine appropriate controls so as not to have a negative impact on workers’ health. The purpose of this study was to analyze the hazards and their impacts on workers’ health through hazard identification measures, exposure assessments, risk assessments and control recommendations. Methods: Health Risk Assessment of physical and chemical hazards in the Painting Area was undertaken using a semi-quantitative method by calculating a risk assessment matrix using the guidelines from IPIECA & OGP in 2016. Results: Physical hazards were found in the form of lighting hazards, vibrations (arm vibration and whole body vibration), noise and heat pressure. Meanwhile, chemical hazards were found in the form of thinner vapor, solvent, NaNO3, H2SO4, NaOH, H3NSO4 and indoor air quality (CO, NO2, SO2, H2S). The results of the risk assessment matrix obtained 4 levels of risk hazards, consisting of 11.1% in the first priority, 50% in the second priority, 25.9% in the third priority and 12.9% in the condition that did not require immediate action. Conclusion: Physical and chemical health hazards were at 4 levels based on the calculation of risk control priorities. A hierarchy of risk control could be used to reduce the risk of health hazards.Keywords: health risk assessment, ipieca & ogp 2016, painting area, risk assessment matrix

Benzene Exposure on Rig X from Drilling Fluid and Effectiveness of Local Exhaust Ventilation William William; Sjahrul Meizar Nasri

Introduction: Benzene is a carcinogenic compound commonly found in drilling fluid, a chemical used in oil and gas drilling operations. Benzene exposure to workers is known to cause acute and/or chronic disease. Adequate control measures shall be identified and implemented to prevent the adverse health effects of benzene from the utilization of drilling fluid. Methods: This study measured benzene concentrations at several locations, above the drilling rig, which has the potential risk of benzene vapor exposure. From the measurement results, if the threshold limit value was exceeded, LEV was proposed to be installed and the effectiveness of LEV at each location would be assessed. A two-tailed t-test was used with a confidence level of 95% (α=0.05) to measure the effectiveness of LEV. Results: In several areas, benzene concentration exceeded TLV-TWA, and LEV was installed in those areas as control measures. In this study, it was found that LEV was not always effective in reducing the concentration of benzene in some areas. Conclusion: Drilling fluid was essential for drilling activity, and this could cause benzene vapor to contaminate the working area. The installation of the LEV shall consider the type of containment through which the drilling fluid flows to ensure the mitigation measures are effective to reduce the concentration of benzene in the air that may be exposed to workers.Keywords: benzene, drilling fluid, exhaust ventilation

Introduction: Mold may affect the Indoor Air Quality (IAQ) in workplace dormitories. This study aims to investigate indoor air factors that affect molds growth in a dormitory of an LNG Company in Indonesia. Several indoor air determinant factors, including relative humidity, general temperature, wet temperature, dry temperature, air velocity, illumination, particulate matter, and carbon dioxide concentration were assessed against the growth of microorganism colonies. Methods: This study was a cross-sectional study using a 2 (two)-stage Andersen sampler based on NIOSH 0800 Bioaerosol Sampling Method for Indoor Air Quality for viable bioaerosol sampling. Bioaerosol samples were collected from 50 indoor, corridor, and outdoor sampling points. The total colony count for bioaerosols (TCC) was then determined (CFU/m3). Ten indoor air quality parameters, i.e., relative humidity, general temperature, wet temperature, dry temperature, air velocity, illumination, particulate matter, and carbon dioxide concentration, were measured. Results: The average mold colony concentration in the dormitory rooms was higher (703.1 CFU/m3) than the maximum standard issued by the Ministry of Health of the Republic of Indonesia (< 700 CFU/m3) while the relative humidity was very high (84.4% RH on average), with a direct relation between the humidity and the mold colony concentration. A significant correlation was also identified between mold colony concentration, wet temperature, and CO2 concentration. Conclusion: Significant correlations between bioaerosols, relative humidity, wet temperature, and indoor CO2 concentration indicate insufficient ventilation and poor indoor air quality in the dormitory.
