1 EVALUATION OF EVACUATION AT FACULTY ENGINEERING

2 INTRODUCTION

3 INTRODUCTION The seven story building fitted with three lifts lies partially on a lake. It houses offices for the Dean, Deputy Deans and eight engineering departments as well as rooms for professors (JUSA A, B and C) and associate professors, senior lecturers and other academic staff. This is the biggest engineering faculty in Malaysia in terms of the number of programmes offered and the number of postgraduates. Each lecturer office has one wall almost covered with glass, standard government size fitted with individual air conditioner, PA system, sprinkler head and four foot fluorescent lights. The objective of this work is to evaluate fire safety components using manual and commercial software.

4 LITERATURE REVIEW

5 Fire Services act 1988 (act 341) Regulation, Rules and Order Computer simulation Best assembly area Literature Review Fire drilss Fire fighting access lobbies Stairs Means of egress

6 FIRE SERVICES ACT 1988 (ACT 341) REGULATION, RULES AND ORDER Fire Services act 1988 (act 341) is an act that make provision for the effective and efficient functioning of the Fire Services Department for the protection of persons and property from the fire risk and for purposes connected with it. (Fire Services Act 1988, 2006)

7 BEST ASSEMBLY AREA Assembly area is an area where located outside the building in an open space so everyone can gather and be identified but the area should be clearing indicate by all occupants before emergency arise. (Uniform Building By Law 1984, 2011)

8 FIRE FIGHTING ACCESS LOBBIES Fire safety should conform to the following requirements: Each lobby shall have a floor area of not less than square meters (Uniform Building By Law 1984, 2011) The open able area of windows or area of permanent ventilation shall be not less than 25% of the floor area of the lobby and if ventilation is by means of open able windows, Additional permanent ventilation having a free opening of 464 square centimeters shall be provided except that mechanical pressurization may be provided as an alternative. (Uniform Building By Law 1984, 2011)

9 HEAT LOAD The heat load is the maximum heat that can be theoretically generated by the combustible items and contents of the structure. The heat load could be measured as the weight of the combustible material multiplied by the calorific value per unit weight. Heat load is conveniently expressed in terms of the floor space as MJ/m 2 or Mcal/m 2.More often it would be expressed in terms of equivalent quantity of wood and expressed as Kg wood / m 2 (1 Kg wood = 18MJ). The amount of heat load and the values may change from one environment to the other and also from country to country (Patterson, 1993)

10 MEANS OF EGRESS A means of egress is an exit path that occupants may use to safely exit a building. It is designed to provide safe and easy travel during a fire or other emergency so that the risk of injury or death is minimized. (Uniform Building By Law 1984, 2011) Components of means of egress Doors Stairs Guards and handrails Smoke proof enclosures Stair pressurization Horizontal exits Exit passageways

11 STAIRS Stairs for emergency during fire has their own dimension that need to follow by rules that stated in Uniform Building By Law 1984.the dimension that be suggested by the law is the rise of any staircase shall not be not more than 180 millimeters and tread shall be not less than 255 millimeters and dimension of the rise and the tread of the staircase so chosen shall be uniform and consistent throughout. Other than that, the width of staircase shall be in accordance by law 168 while the depth of landings shall be not less than the width of the staircase. (Uniform Building By Law 1984, 2011)

12 FIRE DRILLS Fire drill is an exercise in the use of firefighting equipment or the evacuation of a building in case of a fire There are 4 stages that will be analyze during the fire drills, which are 1-Time before fire been aware (Δtdet) 2- Be aware of fire (Δta) 3 - Identify and respond to sound the alarm (Δtpre) 4 - Start clear the building and move to a place of assembly secure (Δttrav)

13 PYRO SIM SOFTWARE Pyro Sim is a graphical user interface for the Fire Dynamics Simulator (FDS). FDS models can predict smoke, temperature, carbon monoxide, and other substances during fires. The results of these simulations have been used to ensure the safety of buildings before construction, evaluate safety options of existing buildings, reconstruct fires for post-accident investigation, and assist in firefighter training. (Engineering, 2010)
