    The most fire-related fatalities are due to the smoke inhalation of the toxic gases. It is related to the victims being trapped in the building when the building was on fire. It was also reported that major deaths from fire related are from the toxic gases inhalation produced by the fire while the deaths due to fire flames and burning was about one third of the total deaths. The access to the exit door was blocked and they could not exit through the window due to the permanent grille installation. It was well aware that most Malaysian homeowners installed grilles on their house windows or doors for security reason since there are lots of break-ins incidences. To overcome the issue, this work introduces a window grille with keyless locking system. The design incorporated keyless system that can be operated or opened without a key. Several designs for implementing this solution have been described. These designs are divided into three sections, which is a grille design, expansion designs which use to accommodate a wide range of window-sized and keyless locking systems. The size and type of grille suitable for Malaysian residents as well as the more efficient keyless locking system has been studied in detail using the method of case study and survey method. Step of patent research, market analysis and benchmarking are used as methods for collecting reference data. The most effective fire escape window grille keyless locking system has been studied and designed from this project. An important factor in designing a fire window grille is the design that can be opened and does not require a key operation. The results of the design and analysis tested are presented such that they can be used as an aid to the design of fire escape features.

    Laser welding on dissimilar materials is widely used and has significance application in industry. Laser welding is the one of the method which can offer high strength of joint especially for joining of dissimilar metals contrast to conventional method. Conventional welding more often had an insufficient penetration depth and a wider heat affected zone which prompts to reduce joint quality. This work exhibits a weld possibility on low carbon steel and high carbon steel surface utilizing low power fiber laser in pulse wave modes. The objective of this research work is to investigate the influence of laser welding parameters of welding speed and pulse width on weld geometry of the welded metal. The parameters used is the welding speed (1.67 mm/s to 8.33mm/s) and pulse width (3 ms to 5 ms). The optimum weld geometry was with the largest aspect ratio (1.42) with parameter of welding speed (1.67 mm/s) and pulse width (3.0 ms). As conclusion, appropriate utilization of parameters can improve the quality of weld joints and durability of products.
