  • Background: Despite considerable efforts made in recent years, the industrial accident rate and the fatality rate in the Republic of Korea are much higher than those in most developed countries in Europe and North America. Industrial safety policies and safety regulations are also known to be ineffective and inefficient in some cases. Methods: This study focuses on the quantitative evaluation of the effectiveness of direct safety regulations such as safety certification, self-declaration of conformity, and safety inspection of industrial machines in the Republic of Korea. Implications on safety policies to restructure the industrial safety system associated with industrial machines are also explored. Results: Analysis of causes in industrial accidents associated with industrial machines confirms that technical causes need to be resolved to reduce both the frequency and the severity of such industrial accidents. Statistical analysis also confirms that the indirect effects of safety device regulation on users are limited for a variety of reasons. Safety device regulation needs to be shifted to complement safety certification and self-declaration of conformity for more balanced direct regulations on manufacturers and users. An example of cost-benefit analysis on conveyor justifies such a transition. Conclusion: Industrial safety policies and regulations associated with industrial machines must be directed towards eliminating the sources of danger at the stage of danger creation, thereby securing the safe industrial machines. Safety inspection further secures the safety of workers at the stage of danger use. The overall balance between such safety regulations is achieved by proper distribution of industrial machines subject to such regulations and the intensity of each regulation. Rearrangement of industrial machines subject to safety certification and self-declaration of conformity to include more movable industrial machines and other industrial machines with a high level of danger is also suggested.

  • Background: Despite the recent efforts to prevent industrial accidents in the Republic of Korea, the industrial accident rate has not improved much. Industrial safety policies and safety management are also known to be inefficient. This study focused on dynamic characteristics of industrial safety systems and their effects on safety performance in the Republic of Korea. Such dynamic characteristics are particularly important for restructuring of the industrial safety system. Methods: The effects of damping and elastic characteristics of the industrial safety system model on safety performance were examined and feedback control performance was explained in view of cost and benefit. The implications on safety policies of restructuring the industrial safety system were also explored. Results: A strong correlation between the safety budget and the industrial accident rate enabled modeling of an industrial safety system with these variables as the input and the output, respectively. A more effective and efficient industrial safety system could be realized by having weaker elastic characteristics and stronger damping characteristics in it. A substantial decrease in total social cost is expected as the industrial safety system is restructured accordingly. Conclusion: A simple feedback control with proportional-integral action is effective in prevention of industrial accidents. Securing a lower level of elastic industrial accident-driving energy appears to have dominant effects on the control performance compared with the damping effort to dissipate such energy. More attention needs to be directed towards physical and social feedbacks that have prolonged cumulative effects. Suggestions for further improvement of the safety system including physical and social feedbacks are also made.

  • The Honorary Industrial Safety Inspector System, which is with the object of establishment of an autonomic and collaborative industrial accident prevent system, comes into force on 1995 through the administration provision of the Ministry of Labor, one year after it had legal basis. The purpose of this study is to put forward revitalization of the Honorary Industrial Safety Inspector System by using the survey(2005.05) of the Honorary Industrial Safety Inspector in the manufacturing industry. It can be summarized to develop the system as the following: 1) Obligation to the appointment of the Honorary Industrial Safety Inspector and the Extension to be appointed workplace, 2) Cooperation of the Safety/Health Manager with the Honorary Industrial Safety Inspector, 3) Grant the Honorary Industrial Safety Inspector to make the round of the workplaces for the providing guidance to workers, 4) Employers' fulfillment of the Honorary Industrial Safety Inspector's recommendations, 5) Guarantee the Honorary Industrial Safety Inspector instructions and its hours.

A study on the necessity and validity of NCS based neo-qualification plan qualification item in Occupational Safety and Health Management field (산업안전보건관리 분야의 NCS기반 신(新)자격 설계 자격종목의 필요성과 타당성에 관한 연구)

  • The study conducted questionnaire analysis to 413 industrial safety field employees in order to examine the necessity and validity of industrial safety field's 17th neo-job classification based on National Competency standards(NCS). As a result, 50.1% of industrial safety management field and 43.3% of industrial health management field answered that classification details of occupational safety and health management field are classified by job(duty) performance. Industrial safety management field recognizes that management and engineering section play a significant role in their work, while industrial health management field recognizes worker's health care and work environment management and overall control of work environment assessment to be significant in their work. Furthermore, industrial safety management field recognizes that separating qualification and foundation of 'construction safety manager', 'chemicals(safety and health) manager', '(toxic)risk assessment evaluator or risk factor manager' to be highly significant. The study is meaningful in that it suggests industrial safety field's qualification items practical in industrial sites.

  • It is extremely important to design safety-guaranteed industrial processes because such process determine the ultimate outcomes of industrial activities, including worker safety. Application of artificial intelligence (AI) in industrial safety involves modeling industrial safety systems by using vast amounts of safety-related data, accident prediction, and accident prevention based on predictions. As a preliminary step toward realizing AI-based industrial safety in Korea, this study discusses neural network-based modeling of industrial safety systems. The input variables that are the most discriminatory relative to the output variables of industrial safety processes are selected using two information-theoretic measures, namely entropy and cross entropy. Normalized frequency and severity of industrial accidents are selected as the output variables. Our simulation results confirm the effectiveness of the proposed neural network model and, therefore, the feasibility of extending the model to include more input and output variables.

  • The purpose of this study was to investigate the toxic effects of iso-butylalcohol on Sprague-Dawley (SD) rats which were treated 0, 333, 1,000 and 3,000 ppm for 6 hours a day, 5 days a week for 13 weeks by inhalation. Iso-butylalcohol did not induce any abnormal change in the viewpoint of clinical signs, feed consumption, ophthalmic test, urinalysis, hematology and blood biochemistry during and at the termination of the inhalation toxicity test. We did not find any abnormal findings in the gross and microscopic observations due to the inhalation of iso-butylalcohol. There was no alteration in relative organ weight owing to the inhalation of the iso-butylalcohol. In conclusion, concentration was 3,000 ppm in rats under the inhalation of 6 hours a day, 5 days a week for 13 week. Iso-butylalcohol did not show any change in the clinical signs, feed consumption, ophthalmic test, urinalysis, hematology and blood biochemistry, together with no alteration in the gross and pathological findings.
