Introduction In the current world, fire safety has put in the forefront when designing major buildings. Fire engineering solutions and risk assessments are adequately carried out in order to satisfy authorities that the building is safe against any form of fire hazard. One such building where fire safety should be put into consideration is the Lowry building in order to satisfy the authorities. Lowry building is a large triangular plaza with a Lifting Footbridge that leads to Trafford Wharfside. It has a high-tech business center that provides quality and serviced premises.
Lowry building triangular in shape with its size of being 5 football pitches. The Lowry stands on 803 concrete piles that have been sunk down into the bedrock. It has approximately 48000tons of concrete, 5263metres squared of glass and 2466tons of steel (The Lowry 2010). This is one of the buildings that require an extensive fire risk assessment as well as installation of fire protective systems. Lowry building has several fire risk measures that will be assessed within the report. It has passive and active fire protection systems.
Other aspects that will be assessed include fixed fire fighting installations used in the Lowry. This comprises of the ‘Sprinkler system’, dry risers, and an Automatic suppression systems. The report will also evaluate fire effects on various building materials including timber, concrete, glass, masonry, and steel used in the premises. Passive and Active fire Protection systems According to Arthur (2004), they are two main fire protection systems that include passive and active protection systems. In case of fire within a building, occupants and fire responder’s safety as well as property protection is accomplished through passive and active fire protection systems.
They reduce the spread of fire either directly or indirectly. Passive fire protection tries to contain the spread of fire by slowing it from spreading. Passive fire protection measures should be provided when a new building is at its planning stage. It can also be undertaken when there is modification of the existing building. This is by use of fire resistance doors, floors, and walls among others. It is crucial to ensure that passive fire protection complies with the associated listing and approval use and compliance so as to provide building codes expectations.
Passive fire protection systems slow fire spread for its origin to other areas of the building thus limiting the damage while providing time for the occupants to evacuate the premises. It also gives them enough time to get to the fire spot or area of refuge. Walls, floors, roof, insulation materials, and linings are non-combustible construction materials that do not burn. Therefore, in case of the fire outbreak, they slow down the spread of fire. Stones and metals do not burn hence when the fire gets into them it stops; they act as barriers to the spread of fire hence it does not move from one area to another.
Other passive fire protection measures include fire dampers in air distribution ducts. This is particularly where there is passing through compartment walls or floors. These assists when fire is trying to spread in well-ventilated areas that may enhance the spread of fire. These dampers reduce fire spread by closing hence preventing fire spread across the barrier. Fire resistance cables usually resist high temperatures hence used in fire resistance management circuits.
They are important in conveying the messages in case of fire break out hence the need for them to have high temperatures resistance cables. Fire barriers in ducts, cavities, roof spaces, and voids are other passive fire protection measures. In most instances, unseen spread of flames and smoke occurs in the ducts, cavities, voids, and roof spaces. Therefore, there is need to reduce the unseen smoke and flame spread through such spaces, cavities, and ducts. This can be achieved by fixing tight-fitting barriers in those spaces as argued by David, (2005).
