Description
Buildings housing computer centers should be of made of noncombustible construction materials to reduce the chance of fire. These facilities must be continuously monitored for temperature, humidity, water leakage, smoke, and fire. Most building codes today require that sprinkler systems be installed.
Remember that water and electrical equipment do not mix. It is preferable to install a dry pipe sprinkler rather than a wet pipe system. Dry pipe systems only allow water into the pipes after heat is sensed. This avoids potential wet pipe problems, such as leakage. In addition, fast-acting sensors can be installed to shut down electricity before water sprinklers are activated. Sprinkler heads should be individually activated to avoid widespread water damage.
Sprinklers
A sprinkler system consists of pipes along a ceiling that contain water under pressure, with an additional source of water for a constant flow. Attached to the pipes, automatic sprinklers are placed at select locations. When a fire occurs, a seal in the sprinkler head ruptures at a pre-established temperature, and a steady stream of water flows.
Research compiled by Hall (2011) shows that sprinklers are an effective and reliable fire suppression strategy for buildings. However, he writes that sprinklers are still rare in most places where people are most exposed to fire, including educational buildings, stores and offices, public assembly properties, and especially homes, where most fire deaths occur. Hall notes that sprinklers are 87 percent effective. When a sprinkler system fails, the most frequent reason (65%) is that the system was turned off prior to the fire. Other
3.1 Investigation of fire safety predictors
The fire safety strategies for almost 1000 fire incidents are investigated in the BC province of Canada. Fig. 2 shows three of the investigated safety strategies for the first 25 fire incidents. In the initial detection strategies, it is found that 67% of the fire incidents were detected visually. It is followed by a smoke alarm device and smoke detector device with 15.6% and 13.9% of the fire incidents, respectively. Regarding the transmission of alarm to fire department, 57.8% of the fires had telephone tie-line to fire department; the coded signal municipal fire alarm system, including telephone and radio systems, is associated with 38.8%, as the second high, of the recorded fires in MURBs. Concerning the taken actions, it is found that around 45% of the fire incidents were extinguished by the fire
