The enterprise are facing potential SHE(safety, health and environment) accident to cause casualties or a financial loss and increasing social responsibility. So, SHE management system has to be voluntarily accomplished rather than passively with regard to SHE regulation. In this study, KW_SHE(Kwangwoon Safety, Health and Environment) management model is developed which materialize self-regulation SHE management system of individual workplace by the research and analysis of many domestic enterprise. This KW-SHE management model is intend to assess work-product vs. management expenses investment and critically evaluated for studying its benefits and limitations

Background: There is growing international recognition of the need for improvements to national chemical management systems for hazardous chemicals. The European Union has recently introduced the concept of 'essential uses' as a new approach to the management hazardous chemicals by limiting their uses. Objectives: This paper examines the concept of essential uses in chemical management and how to apply it through a case study of essential use. This approach is distinct from the current chemical management system, but seeks to improve its potential benefits by effectively restricting or gradually decreasing the use of hazardous substances. Methods: The concept of essential uses was introduced by reviewing the Montreal Protocol on Substances that Deplete the Ozone Layer, Cousins's three essentiality categories applied to PFAS, restriction options assessed in the PFAS restriction proposal under REACH, and the California Safer Consumer Products regulations prioritizing 6PPD in motor vehicle tires. Based on these essential uses concepts for PFAS and 6PPD, uses of benzene were classified in accordance with the essential uses approach for products using benzene in South Korea. Results: The essential use concept is able to manage the restriction and authorization of substances of concern through essential uses and non-essential uses and the feasible substitution of uses and substances. Conclusions: If the concept and methodology of essential uses are clearly established, they can be expected to shift the national chemical management paradigm from regulating substances to limiting uses under the existing substance management system.

Purpose: Through studying the expert's and non-experts panel responses to the questions regarding the attributes of chemical-biological protection cloth quality in terms of the levels of customer demand and technical factors has been studied. We are applied to a QFD matrix with find out the relationship between the selective removal efficiency of chemical-biological cloth and the guidelines of technical approach. Methods: We fabricated several composite of ion-exchange resins with selectively permeable performance designed to facilities water vapor transport and selective adsorption of the harmful gases. With these materials, we characterized on the selectively permeable performance to identify ion-exchange resin with chemical-biological protective cloth. Results: Results showed that ion exchange materials possessed performance with selectively efficiencies as NH3, SOx, NOx and HCl gas. The selective adsorption amount of ammonia and hydrogen gases were $90-80{\mu}g/g$ with TRILITE SCR-BH sulfonated ion exchange resin. The PP non-woven/ion exchange resin adsorbent materials possessed performance with water vapor permeability were 1,100-1,350 g/m2/day, it's was two times high value compare with activated carbon. With these materials, we characterized selectively removal efficiency to identify new ion-exchange material with chemical-biological protective capability. Conclusion: This study shows that a QFD aids in deciding with of the adsorption parameters to optimized with chemical-biological protection cloth manufacturing.

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.

In many chemical plants the change or modification is carried out without proper technical review and hazard analysis, and also without adequate technical staff and procedures for comprehensive monitoring of potential hazards resulting from the change. Such changes sometimes affect to the process safety badly if it is not managed properly. Therefore, in order to prevent major industrial accidents caused by change or modification, and also in order to apply Management of Change procedure easily in the field and minimize economic burden of company caused by plant changes, K-MOC(KOSHA-Management of Change) software has been developed and provided to the chemical industry.

The article 49-2 of Industrial Safety Law requires that all the owners of industrial plants which contains dangerous facilities perform the process safety management. That is, this law requires the owners of industrial plants to take necessary measures to prevent fire, harmful gas leaking, explosion, and other serious accidents that could cause demage and injuries to the employees. So far, domestic chemical plants have tried to invest money and time in safety management. But, such efforts have been made only in chemical plants that were subsidiaries of large business groups. Moreover, since the economic crisis of Korea which is symbolized by the IMF bailout, small and medium size companies could not afford to invest in safety management. Their major concern is to increase productivity and thereby, survive in this crisis. The goal of this research is to develop the process safety management system that can help small and medium size companies to positively secure the process safety management. So, in developing the process safety management system, the financial and practical difficulties of such companies are fully taken into consideration.

This paper deals with scheduling problem of the chemical process system where aircraft parts go through a given sequence of tanks filled with chemical solutions. The system has two hoists which move carriers holding the parts between tanks. A mixed integer programming model is developed from which a maximum throughput schedule can be found for the hoist movements. To show the validity of the model, a real world problem is solved and the results are compared with those with an existing approach.

The new chemicals are developed and circulated without the verified toxicity data. So, the accidents and occupational diseases, such as explosion, fire, suffocation about deadly poisons etc. are frequently to workers. Classifications of chemicals suited with guideline and an offer of correct chemical information data are the molt important thing for the establishment of suitable chemical management system. The GHS (Globally Harmonized System of classification and labeling of chemicals) is based with the chemical classifications and unification plan. The warning symbol and phrases are established for improvements of chemical information data system. According to these unified and improved systematic form of data, and the chemical information data, the workplaces will be presented many chemical safety and risk data correctly. In this paper, we will present constructions and accomplishment contents-based chemical management of workplace through development of chemical information data and the nice using for new chemical investigation and risk assessment of chemicals in workplaces.
