With the decrease of the agricultural population in Korea, the workers who is vulnerable to labor are increasing in agricultural industry because of aging,feminization of population. They are exposed in poor working environment with higher temperature and concentrations of dust, gas. Higher concentrationof harmful gas and dust can cause chronic and acute disease to workers depending on exposure intensity and frequency. In order to improve the workingenvironment in the livestock facilities, It is important to secure monitoring data of the thermal environment and the concentration of harmful gases andfine dust. Multi-point measurement was performed to analyze the regional environmental conditions in the pig rooms. When analyzing the workingenvironment, video monitoring was conducted to analyze the concentration changes of ammonia, hydrogen sulfide and fine dust according to workermovement and work type. Ammonia and hydrogen sulfide monitoring result showed 1.5∼2 times higher concentrations than other work when workingin the pigs living zone, and 2∼4 times higher than other work when working to increase the activity of pigs. In the case of fine dust, the result was1.3 times higher than the worker’s exposure standard in a specific work. The concentrations of gases and dusts from pig farms are not of concernfor acute poisoning in normal work, but there is a risk of chronic respiratory disease if they are continuously exposed. Accordingly, there is a needfor development of work environment monitoring device tailored to workers and preparation of alternatives.
Abstract
With the decrease of the agricultural population in Korea, the workers who is vulnerable to labor are increasing in agricultural industry because of aging,feminization of population. They are exposed in poor working environment with higher temperature and concentrations of dust, gas. Higher concentrationof harmful gas and dust can cause chronic and acute disease to workers depending on exposure intensity and frequency. In order to improve the workingenvironment in the livestock facilities, It is important to secure monitoring data of the thermal environment and the concentration of harmful gases andfine dust. Multi-point measurement was performed to analyze the regional environmental conditions in the pig rooms. When analyzing the workingenvironment, video monitoring was conducted to analyze the concentration changes of ammonia, hydrogen sulfide and fine dust according to workermovement and work type. Ammonia and hydrogen sulfide monitoring result showed 1.5∼2 times higher concentrations than other work when workingin the pigs living zone, and 2∼4 times higher than other work when working to increase the activity of pigs. In the case of fine dust, the result was1.3 times higher than the worker’s exposure standard in a specific work. The concentrations of gases and dusts from pig farms are not of concernfor acute poisoning in normal work, but there is a risk of chronic respiratory disease if they are continuously exposed. Accordingly, there is a needfor development of work environment monitoring device tailored to workers and preparation of alternatives.
