Purpose: TThis study seeks to understand the provisions of the Industrial Safety and Health Act and the Construction Technology Promotion Act and to propose measures to prevent serious industrial accidents by seeking to promote safety and health of workers through improvement of safety management at construction sites. Method: A survey was conducted on construction sites with more than 50 permanent workers (5 billion won in construction amount). The analysis of the data was conducted using the JAMOVI statistics program and based on objective data. Result: Multiple regression analysis was conducted to verify the hypothesis of this study, and the results of the analysis. The participation of workers in safety and health activities has the highest impact on the promotion of safety and health of workers. Conclusion: In order to promote safety and health of workers at construction sites, compliance with safety and health rules of workers is required and improvements should be made to allow workers to participate in safety and health activities. 연구목적: 본 연구는 산업안전보건법과 건설기술진흥법의 규정을 파악하고, 건설현장의 안전관리 개선을 통하여 근로자의 안전보건 증진방안 모색하여 중대산업재해 방지 방안을 제안하고자 한다. 연구방법: 본 연구의 표본 대상 범위는 상시 근로자 50인(공사금액 50억원) 이상의 건설현장을 대상으로 설문조사를 실시하였다. 자료의 분석은 JAMOVI 통계 프로그램을 이용하였으며, 객관적인 자료를 바탕으로 하여 분석하는 연구를 진행하였다. 연구결과: 본연구의 가설을 검증하기 위하여 다중회귀분석을 시행하였으며, 분석결과. 근로자의 안전보건 활동 참여가 근로자 안전보건 증진에 가장 높은 영향을 미치는 것으로 나타났다. 결론: 건설현장의 근로자 안전보건 증진을 위하여 근로자의 안전보건 규칙 준수가 필요하고 근로자가 안전보건 활동에 참여하도록 개선되어야 한다고 할 수 있을 것이다.

We generally get the Heat Release Rate by two other method. One is the calculation method from the Oxygen consumption rate and another is the calibration curve method of Temperature rising rate. In this study we compare the results of both test methods with five same specimens. From the test result we get the difference of reproducibility and checked some reasons of the difference. This paper includes some points to be careful for more creditable results for each test method.

Heat Release Rate of the old Saemaul train seat was measured in the ISO 9705 Room Coner facility. Calculated HRR from the conecalorimeter test results of the small specimen was compared with this room test results. Some of the HRR estimation theories of the room test from smaller scale test were discussed in this study. The results of this study will be used for the HRR estimation of the full car.

A case study of fire risk analysis was conducted for train coach which has no gangway doors between coaches. The analysis boundary was limited to the time of outgoing from the coaches for it was train fire risk analysis. ASET(available safe egress time) and RSET(required safe egress time) methodology was used for calculating the dead. 4 liters of gasoline and cable fire at the electric cabinet and the standard fire of EN 45545 were selected for the fire sources. The fire were considered to be occurred at 3 different locations in the car. The train had 3 cases of driving scenarios. The result of all event was summarized for remained tunnel and station egress step.

Diesel locomotive engine is the main source of train noise in these days but hard to reduce the level by barrier for it emitted from high location. For the passing high level noise properties of diesel locomotive engine, there are needs of changing the environmental railway limit to maximum level from equivalent. In this study we investigate the noise characteristics of the diesel electric locomotive according to the change of notch. From the result we found out the frequency of engine cycle noise and the shape of noise spectrum.

The input data for the interior material of the train is one of the key points for enhancing the accuracy of fire simulation. In this study, we investigated the Fire Test Methods for the Fire Dynamic Simulator modeling for railroad passenger trains. We should get the thermal inputs such as ignition temperature, conductivity, specific heat, vaporization heat, effective heat release. With the simple conduction model for cone-calorimeter test, they could get more than HRR. Kinds of methodology were introduced for better thermal data for real material.

A study on the standardization of design fire HRR(heat release rate) curve was conducted for various railcar from the fire simulation or the fire tests. These standard curves are listed on the tunnel fire safety manual whichwill be used for the QRA(quantitative risk analysis) process of the long railway tunnels. The design fire curve is based with four simple factor representing the key of fire curve characteristics. Flashover time maximum HRR and burn out time are the key factors of the design fire curve. Specially total heat release is decided by the burnable material amount in the car.

We investigated the fire characteristics of the subway electric car"s interior materials and evaluated the safety of it. The testing methods are ISO 4589-2 for Limited Oxygen Index, ISO 5658-2 for surface flame spread, ISO 5660-1 for Heat Release Rate, ASTM E 662 for smoke density and BS 6852 Annex B.2 for gas toxicity. The materials of seven organization including KNR were tested. Most of the materials are under the levels of the foreign country"s demand. We also reported the test methods of other countries and compared it to ours.

In this study we reviewed the real scale fire tests of rolling stocks around the world. Especially the tests of NIST, CSIRO and the Japanese case were reported with the Mock Up tests conducted in Korea after the Dague Fire Accident. We also reported the composite car body case test briefly. Some promotion of the test system was considered on the composite body test for more credible results. More adjusted system is need for Fire Test of Real Scale rolling stocks.
