Recently the consideration for occupant's security has been raised as very important design element from the fire by building's large sized, higher storied, and its compounded. But the domestic laws regulated the predicative laws according to the technical standard which has no difference from the past domestic evacuation regulation. Therefore, regulation of escape code and developing technology for Korean conditions are needed to reduce victims during disaster by protecting occupant and guiding people to safe places.

This study is aimed to analyze the flow patterns and thermal characteristics by computer simulation under the variations of fire strength for Daegu-Pahang Yimgo-4th tunnel, from which flow and heat distributions are predicted in the longitudinal tunnel. Though the results of numerical computations, followings are found; one is that the volume flow rate is discontinuously increasing as closer to fire location, and the other is that a critical design to get faster flow rate is required because of existence of backlayer flow for the high fire strength in view of safety for the people in fire of the tunnel.

Nowaday, High strength concrete(HSC) has been mainly used in high rise building. HSC have superior property as well as improvement in durability compared with ordinary strength concrete. In spite of durability of HSC, explosive spalling in concrete front surface near the source of fire occurs serious problem in structural safety. Thus, this study is concerned with experimentally investigation fire resistance of the inorganic fire protection materials at high temperatures up to $800^{\circ}C$. From the test result, developed inorganic binder becomes general that with rising temperature the compressive strength of the material increases in tendency. Therefore, the results indicate that it is possible to fireproof panels, fire protection of materials, etc.

A fire should be accompanied by the heat and smoke. However, smoke is considered main cause of heavy casualties. Smoke easily spreads away from the fire area to remote space and cause mortal wound for the resident. A technical way effectively protecting the life and property from the smoke is the smoke control system of the building. Pressurized air supply system can be considered to prevent the refuge area from the smoke infiltration that evacuate residents via evacuation route for life safety. This paper is related with performance estimation and the effectiveness of the pressurized air supply system through experiments.

This study applied ALOHA Program to predict the damage caused by fire and explosion predicted to occur from gas leakage at LPG stations and presented plans to prevent damages by diagramming the impact range and distance. The propane gas leakage from LPG stations causes human damage like breathing issues and property damage, including building destruction to residents in the surrounding areas. As a way to reduce this, first, the hazardous substance safety manager of the LPG station needs to check frequently whether the meters and safety valves are working properly to prevent leakage in advance. Second, the LPG stations' storage tanks should be worked by the person who received "hazardous substance safety manager training" under the provisions of the Act on the Safety Control of Hazardous Substances and has been appointed as a "hazardous substance safety manager" by the fire department. Third, LPG station's various safety device functions, such as overfill prevention devices, must be checked on a regular basis. Finally, wearing work clothes and shoes that prevent static electricity at LPG stations is highly recommended, as static can cause a fire when gas leaks.

In Korea, performance-based fire safety designs are being discussed to deal with the various risks of fire in complex and diverse types of structure. However, performance-based fire safety designs are not actively employed because it is difficult to estimate the fire characteristics related to the various factors in buildings. In this study, real scale fire tests were conducted based on fire severity levels and fire loads provided in He New Zealand Building Code, in order to use the results as guidelines and fundamental data for performance-based designs. In the real scale fire tests conducted in a 10MW full-scale calorimeter, wood cribs were placed in a $2.4(L){\times}3.6(W){\times}2.4(H)m$ mock-up of a compartment which had one $0.8(L){\times}2.0(H)$ opening for different fire loads and heating was continued until all of the wood cribs were burned down. The heat release rate started to increase rapidly 90 seconds after the wood cribs caught fire. In the test with a fire load level 1, the maximum heat release rate of 4743.4 kW was reached at 244 second. In the test with fire load level 2, a maximum heat release rate of 5050.9 kW was reached at 497 second. In the test with fire load level 3, a maximum heat release rate of 4446.9 kW was reached at 677 second.

The 2020 National Building Code of Canada (NBC) and the 2021 International Building Code (IBC) both include Tall Wood Buildings (TWB) and are hailed as documents responsible for the proliferation of Mass Timber construction. Mass Timber construction is critical to reducing the carbon footprint of the construction industry; a sector acknowledged as being one of the greatest contributors of global annual CO₂ emissions. Origine, a 13-storey multi-residential building erected in 2017 in a previously unsuitable site, is currently the tallest all-wood building in North America. This article describes the challenges overcome by the designers and client as they engaged with code officials, building authorities, and fire-service representatives to demonstrate the life-safety performance of this innovative building. It also traces the development of the "Guide for Mass Timber Buildings of up to 12 Storeys" published in Quebec and how it has enabled other significant Tall Wood projects across North America.

There are researches are in progress on ensuring the safety of the high impact concrete in cases of fire which is a current rising social problem and this research institute also developed PFB technology, the explosion preventing technology. PFB technology is to apply POSCO E&C Fire Board, a fireproof board, with an adhesive agent on the construction site, and this technology passed 3-hour fireproof test and this technology was proven from a previous research that the temperature of main root is maintained under 200 ℃. Therefore, tests on basic contents to be examined before the actual construction in this research by with a wooden prototype of a full scale to apply PFB technology to actual construction sites and tests are being done on the workability of fireproof board, the adhesive power, the resistance against imprint of wooden nail, the heat conductivity and etc. As the results of those tests, PFB technology was proven to have an excellent workability at a construction site and to be easy for processing and also this technology was proven to have a great the resisting power against imprint of wooden nail, so this research has confirmed that PFB technology has no problem to be applied on a construction site.

This study analyzes the present public construction ordering system focussing on the legal framework for the fire facilities construction business and investigates the problem of subcontracting, and further reviews why Separate Prime Contracting should be recommended in policy, social, legislative and regulative terms. This study suggests the amendment of Fire Facilities Construction Business Act, with new bill drafting. The result of this study shows the present public construction ordering system has huge disparities between main building construction business and fire facilities construction business, and recommend Separate Prime Contracting should be adopted in the fields of fire facilities construction business. The system of Separate Prime Contracting may secure business entities' responsibility and higher quality of fire facilities, and also result in reasonable construction practices in reasonable costs. This system may also contribute to improve public safety level in fire facilities construction.
