Objective: This study was performed to propose a domestic occupational exposure limit(OEL) following a health hazard assessment, calculation of a non-carcinogenicity reference concentration worker($RfC_{worker}$) value, and examination of international agencies' exposure limits. It also recommends legal management within the Occupational Safety and Health Act for PHMG-Phosphate(CAS No. 89697-78-9), It is a humidifier disinfectant that generated many lung injuries. Methods: We have investigated the recommendation or guidelines of foreign OEL for PHMG-Phosphate and the actual state of legal management in Korea. To examine the procedures and methods for recommendation OEL. Toxicological hazard and health hazard classifications were examined and a non-carcinogenicity $RfC_{worker}$ value was calculated for PHMG-Phosphate. An OEL and the necessity of legal management were recommended as well. Results and Conclusions: The OEL for PHMG-Phosphate is recommended to be $0.01mg/m^3$. The recommended OEL is close to 10 times the RfCworker value of $0.000833mg/m^3$ calculated from the chemical dose-response hazard assessment, which is a 2017 study. The CMIT/MIT(3:1) mixture, which was a social issue as a humidifier disinfectant substance, was also exposed to the same ratio in March 2018, establish the OEL. It is recommended to establish OEL for PHMG-Phosphate to prevent worker health hazards and for chemical safety management.

연구목적: 사업장 주변에 배출되는 화학물질의 양을 선정하여 대기확산 프로그램으로 농도를 예측하여 인근 주민들에게 영향을 정량적으로 파악하는 것을 목적으로 하였다. 연구방법: 연구물질의 선정은 반감기, 독성, 이용 가능한 측정소 자료의 유무를 고려하였다. 또한 연구대상물질에서 배출되는 지역을 연구대상 지역으로 선정하였으며, 유동인구가 있는 4개 지역을 선정하여 건강위해성을 평가하였다. 연구결과: AERMOD를 구동하기 위하여 지형 및 기상 처리를 실시 후 예측 농도를 구하였다. 위해성 평가 결과 어린이에서만 디클로로메탄이 초과되는 것으로 나타났으나, 테트라클로로에틸렌과 클로로포름은 어린이와 성인 모두 무시할 수 없는 수준으로 나타났다. 결론: 현재 국내 건강위해성평가는 "환경보건법"의 규정에 따라 위해지수가 일정 기준을 초과할 경우 위해성이 있는 것으로 간주된다. 향후 화학물질배출계획서 대상물질이 2030년에는 415종으로 확대되어 사업장에서 효율적인 관리가 필요함을 시사한다. 위해성 평가에서 위해성지수를 초과하는 경우 대기확산 모델링을 통해 배경농도와 예측농도를 고려하여 우선순위를 부여함으로써 화학물질 관리를 효과적으로 수행할 수 있을 것으로 판단된다.

본 연구에서는 가스 산업 시설에서의 적합한 잠재위험성 확인 기법을 선정하기 위해 가스 산업 시설 및 12가지의 기법들을 분석하고, 기법 선정에 영향을 미치는 6가지의 요소를 적용하여 기법 선정에 대한 guideline을 제시하였다. 합리적인 기법의 선정을 위해서 선정에 영향을 미치는 요소들과 각 공정 또는 설비별 사고 발생의 원인과 결과를 8가지의 특성으로 분류하여 4가지의 index를 작성하였다. 또한, flowchart 형식의 의사 결정 과정에 작성된 index를 대입하여 사용이 부적합한 기법들을 소거하고, 최적의 기법 사용에 대한 대안을 제시할 수 있도록 하였다. 또한, 규제요건 비대상 사업장의 자체적 내부 안전성 향상을 위한 guideline으로 활용될 수 있을 것이다.

Objective: The purpose of this study was to investigate the hazards of cosmetic ingredients in Korea. Methods: An Excel database of cosmetic ingredients was developed on a website(Korea Cosmetic Ingredient Dictionary) and used for a hazard assessment based on Tox-free, a database containing toxic information such as on carcinogens, mutagens or reproductive toxicants(CMRs) and endocrine disrupting chemicals(EDCs), as well as other regulated chemicals in Korea. Results: A total of 16,605 chemicals were registered with the cosmetic ingredient dictionary and 308 of them were identified as either CMRs or EDCs. CMRs included formaldehyde and nickel gluconate, and EDCs included parabens, benzophenon, styrene, and toluene. Reproductive toxicants such as xylene, zinc chloride, toluene, and formaldehyde were regulated by the Occupational Safety and Health Act and the Act on the Registration and Evaluation, etc. of Chemical Substances(the Chemical Control Act). Conclusions: Regulations on cosmetics components should be strengthened, and the right to know about cosmetics containing hazardous chemicals should be guaranteed.

Occupational use of cleaning products can cause asthma in healthcare workers but the cleaning agents responsible are not yet known. This study aimed to identify respiratory and other hazards in cleaning products on the National Health Service (NHS) supply chain online catalogue and used in the NHS. Information on cleaning products, their composition, and H-statements that identified hazard characteristics of chemical substances in them was obtained from chemical safety data sheets (SDSs). Furthermore, a quantitative structure-activity relationship model and a published asthmagen list were used to identify potential additional respiratory hazards. 473 cleaning products and 229 substances were identified. SDSs reported only 4 respiratory sensitizers but an additional 51 were suggested by the other 2 methods. In contrast, 25 respiratory irritants were identified using SDSs and only one from the asthmagen list. This comprehensive overview of cleaning agents' hazards has potential use in future risk assessment and epidemiological studies.

The Ministry of Employment and Labor announced a roadmap for reducing serious accidents to create a "safe and healthy workplace, happy Korea" and ordered a risk assessment for all work processes in all workplaces on November 30, 2022. Accordingly, even workplaces that handle new chemicals must conduct risk assessment when introducing new chemicals, but the risk assessment techniques currently proposed by the government focus on preventing conventional accidents such as falls, getting caught, and bumping. Currently, there is a Chemical Hazard Risk Management (CHARM) technique that is most commonly used for chemical risk assessment, but in small and medium-sized businesses that lack professional manpower related to chemical substances, there are many technical terms in the technique and it is difficult to interpret, so its utilization is very low. Therefore, the purpose of this study is to present a method that can make risk assessment easier and simpler before handling new chemicals so that it can be used well in small and medium-sized businesses that lack professional manpower related to chemical substances. Through actual cases, the method of using CHARM was confirmed step by step, and based on this, risk reduction establishment and execution methods were derived. Based on the results of this study, it is expected that it will be used as the best tool for preventing accidents such as acute poisoning when handling chemicals in small and medium-sized workplaces that lack professional manpower related to chemical substances and make every effort to protect workers' health.
