Objectives: The study was performed to investigate characteristics of hazardous factors regarding chemical(liquid lime) tank dredging workers by case survey. Methods: Field data such as working condition, MSDS and respirators applied to chemical tank dredging work were analyzed and the work environmental factors of noise and indoor air quality were measured to compare existing data with actual work situations. Results: No health hazards to workers due to working conditions were confirmed during dredging work inside the chemical storage tank. All air quality measurement data during dredging work satisfied the management standards, and there were no by-products. During dredging work, there was a significant change in noise depending on the type of work, but considering the noise reduction rate(NRR) of the earplugs worn by workers, there was no actual health hazard due to noise exposure. Conclusions: A fit test for respirator and the expiration date of the safety helmet should be observed to ensure an appropriate level of safety and health for dredging workers in the chemical storage tank.

BACKGROUND: Chemical accidents have increased owing to chemical usage, human error and technical failures during the last decades. Many countries have organized supervisory authorities in charge of enforcing related rules and regulations to prevent chemical accidents. A very important part in chemical accidents has been coping with comprehensive first aid tool. Therefore, the present research has provided information with the initial applications concern to the rapid analysis of hazardous material using instruments in vehicle of field mode after chemical accidents. METHODS AND RESULTS: Mobile measurement vehicle was manufactured to obtain information regarding field assessments of chemical accidents. This vehicle was equipped with four instruments including gas chromatography with mass spectrometry (GC/MS), Fourier Transform Infrared Spectroscopy (FT-IR), Ion Chromatography (IC), and UV/Vis spectrometer (UV) to analyses of accident preparedness substances, volatile compounds, and organic gases. Moreover, this work was the first examined the evaluation of applicability for analysis instruments using 20 chemicals in various accident preparedness substances (GC/MS; 6 chemicals, FT-IR; 2 chemicals, IC; 11 chemicals, and UV; 1 chemical) and their calibration curves were obtained with high linearity ( r ² > 0.991). Our results were observed the advantage of the high chromatographic peak capacity, fast analysis, and good sensitivity as well as resolution. CONCLUSION: When chemical accidents are occurred, the posted measurement vehicle may be utilized as tool an effective for qualitative and quantitative information in the scene of an accident owing to the rapid analysis of hazardous material.

Objectives: To protect individuals working at the site as well as the surrounding general population from a chemical accident, several emergency exposure guidance levels have been used to set a level of concern for certain chemicals. However, a level of concern has not been established for many substances that are frequently used or produced in large quantities in Korean workplaces. In the present study, we investigated the guidance levels for protecting populations from chemical exposure and the estimation of level of concern using acute inhalation and oral toxicity data. Methods: The number of chemicals to which emergency exposure guidance levels (e.g., ERPG-2, AEGL-2, PAC-2, and IDLH) can be applied were determined among 822 hazardous chemicals according to the 'Technical Guidelines for the Selection of Accident Scenarios (revised December 2016)'. The ERPG and AEGL values were compared across all three tiers for the 31 substances that appeared on both lists. We examined the degree of difference between the emergency exposure guidance levels and the estimates of level of concern calculated from acute inhalation or acute oral toxicity data. Results: Among the 822 hazardous chemicals, emergency exposure guidance levels can be applied to 359 substances, suggesting that the estimates of level of concern should be calculated using acute toxicity data for 56.3% of the hazardous chemicals. When comparing the concordance rates of ERPG and AEGL for 31 substances, the difference between the two criteria was generally small. However, about 40% of the substances have values diverging by more than three-fold in at least one tier. Such discrepancies may cause interpretation and communication problems in risk management. The emergency exposure guidance levels were similar to the estimates of level of concern calculated using acute inhalation toxicity data, but the differences were significant when using acute oral toxicity data. These results indicate that the level of concern derived from acute oral toxicity data may be insufficient to protect the population in some cases. Conclusion: Our study suggests that the development of standardized guidance values for emergency chemical exposure in the Korean population should be encouraged. It is also necessary to analyze acute toxicity data and fill the information gaps for substances that are important in Korean workplace situations.

In this study, we have developed the database of safety and health information for pesticide active ingredients used in Korea. There were 1,283 pesticide items among which 296 were found to be out of use in current. A total of 349 pesticide ingredients were being used in Korea. The database consists of 32 types of information including chemical characteristics, acute toxicity, chronic toxicity (carcinogenic and reproductive toxicity), specific symptoms by exposure route and first aid. When pesticide ingredients were assessed in terms of key properties such as color, odor, acute toxicity, carcinogenic and reproductive toxicity, they were white, colorless and odorless, in general. When ingredients were classified by category of acute toxicity, 'Non-hazardous' represented 29%, followed by 'Slightly hazardous' at 16%, 'Moderately hazardous' at 14%, 'Highly hazardous' at 5%, and 'Extremely hazardous' at 2%. 85 out of 349, or 24% of ingredients were found to be possibly carcinogenic to human. This database is expected to provide an easy access for farmers, agriculture supervisors, researchers and consumers, and it can ultimately be used as basic data on farmer's safety and health.

본 연구는 화학물질 운송 화학사고를 대상으로 각 연도별 사고현황, 사고유형, 사고원인 등의 화학사고 특성을 분석하였다. 그 결과 77건의 운송 화학사고 중 74건이 유 누출 유형에 의한 사고였으며, 사고 원인으로는 41건이 교통사고에 의한 화학사고였다. 또한, 사고다발 화학물질 조사에서는 46건의 사고가 유해화학물질에 의한 사고인 것으로 조사되었다. 화학물질 운송 화학사고의 예방 및 대응을 위해서는 화학물질 유 누출과 화학물질의 운송 교통사고에 의한 화학사고에 대한 예방책의 보완이 필요하며, 운송 화학사고가 발생되었을 경우 방재가 시스템적으로 신속히 이루어질 수 있도록 범국가적이고 체계적인 화학물질 운송안전 시스템을 구축하여 화학물질 운송에 적용하는 것이 필요하다.

사업장에서 유해가스를 처리하는 스크러버는 처리효율은 높으나 설계가 복잡하고 24시간 펌프를 가동시켜야 하므로 많은 비용이 소모될 수 있다. 따라서, 영세한 사업장에서는 스크러버를 설치하지 않거나 순환펌프의 작동을 중지한 상태로 스크러버를 운용하여 운영비를 최소화하고 있다. 이에, 본 연구에서는 소규모 사업장에서 경제적으로 활용할 수 있는 저비용 고효율 스크러버에 대한 적용방안을 연구하였다. 저비용 고효율 스크러버는 bubble column의 방식을 적용하여 유해화학물질 흡수처리 목적으로 장치를 활용하는 것으로, 이러한 스크러버의 개발을 위하여 실험을 통해 흡수성능을 검토하였으며 특정 조건에서 물리적 조건 변화에 따른 유해가스 흡수효율 변화 및 최적의 적용방안을 연구하였다. 그 결과, 저비용 고효율 스크러버로 유입되는 기체를 어느 정도 처리할 수는 있었으나 처리능력이 저하되는 문제가 발생하여 흡수액 공급을 통해 성능저하를 방지하고 순환량에 따라 일정 수준의 흡수율을 유지할 수 있는 것을 확인할 수 있었다. 이를 기반으로 최종적으로는 적정 순환시점 및 동결 방지방안을 포함한 저비용 고효율 스크러버의 현장 적용방안을 3가지 방식(type)으로 제시하였다.
