Such devices include heat detectors, smoke detectors, flame detectors, fire gas detectors and water flow detectors. Modern innovation can use cameras and computers to analyze the visual signs of fire and movement in applications inappropriate for or hostile to other detection methods (Greenman, 2003).
Notifications from fire alarms to alert the occupants of the need to evacuate premises or take appropriate actions due to fire emergencies can be in audible, visible, tactile, textual or even olfactory (odorized) forms. Emergency signals are automatically intended to be distinct and understandable in order top avoid confusion with other signals. The Temporal Code 3 which chimes three times at one-second intervals, stops for one second the repeats is the most common audible in the modern fire alarm system. Other methods of audio alerts include audible textual appliances, continuous and voice evaluation. In some fire alarm systems especially in high-rise buildings, arenas and other large facilities such as hospitals where total evacuation is difficult to achieve, emergency voice alarm communication systems (EVACS) are used. This voice based system allows personnel to orderly evacuate and notify occupants in such crowded buildings. Strategically too, especially in high-rise buildings, depending on exact location of fire, different evaluation messages may be played on each floor to facilitate orderly evacuation and saving of lives (Jones, 2009).
New codes and standards have enabled alarm system manufacturers to expand their systems voice evacuation capabilities to support trending requirements for mass notifications including possibility of multiple types of emergency messaging. To serve those with disabilities too, emergency communication systems have visible notification along with audio. Mass notification systems ...Download file to see next pagesRead More

... Fire Protection Beattie, Walter S. Handling Impairments to Fire Protection Systems. Professional safety, Vol. 53(10), 2008, pp. 60-63. Beattie (60) explains that most occurrences of industrial fires have been noted to happen when systems are impaired or out of use. Hence facilities that detect and protect fires always have to be installed so that in case of any occurrence, the fire will be easily contained. Though these facilities have been installed in a number of industrial places, disaster management bodies have recommended that the installation to be extended to residential apartments. It is also very important to train individuals to know how to use them in order to reduce damage in case of a fire emergence (Beattie 62...

... of IFC and NFP 1, this limit is 150 feet for all buildings that lack complete sprinkler systems. However, there is a provision to low this distance to exceed up to 450 feet. Fire protection experts refer to this distance from of the building to a fire lane or road as the “setback distance”. There are other guidelines regulating access location, with differences in height, size, and sprinkler protection (Corte 127). To effectively combat fire hazards and prevent loss, harm or injury, it is important for the structure or area of the incident to be accessible. This aspect is included in NFPA and IBC as the ‘frontage increase’. Buildings and structures should ideally be accessible, but a certain limit percentage exists that all building...

... Decibel Ratings Problem: A residence requires smoke alarms within a bedroom and in the corridor directly outside the bedroom. The ambient noise level in the bedroom is 60 dB and a solid core door reduces noise by 25 dB. Determine the minimum decibel ratings for the bedroom smoke alarm and the corridor smoke alarm. According to the NFPA 72 National Fire Alarm Code, the following guidelines for fire alarm decibel ratings must apply: Sleeping area audibility requirements 15 dB above average ambient sound levels, or 5 dB above maximum ambient sound level or 75dB whichever is greater Corridor fire alarms must be audible to all occupants of the floor From this information, we can compute for the required decibel ratings: Solution for Bedroom...

Fire Protection

...FIRE PROTECTION HYDRAULICS AND WATER SUPPLY Hydraulics is the branch of physics which study the mechanical properties of water and other liquids in motion with the application of these properties in engineering. Hydrodynamics is the study of the motion and action of water and other liquids. Hydrostatic is the balance of water and other liquids and the pressure exerted by them at rest. For all intents and purposes hydraulics (Greek: Hydro meaning water; Aulos meaning pipe), as it relates to the fire service is the study of the behaviour of water in motion or at rest. Water is the main fire-extinguishing medium used by the fire service because it is relatively cheap and readily available. Even if is not the primary extinguishing agent...

... involvement. These systems include Fire Protection systems, Fire Prevention systems, Fire Control systems, Fire Suppression systems, Fire spray systems and Explosion suppression systems etc are now in use of both at organizational and individual level. Fire spray systems are specifically design to suppress the fire and it throws water within the 100 milliseconds to lessen the damage at its maximum potential. While the explosion suppression systems work to detect and suppress the explosion as early a possible because time is a crucial factor in the whole process. These fire protection systems work either in Active form or Passive. Active fire protection systems work in an automatic way, like the fire sprinkles, alarms etc., in order to get...

... generated will be smaller than in the absence of smoke. A signal is thus generated which gives off the alarm. Fire detectors need to regularly serviced and checked since there always exists a possibility of the devices giving false alarms. Water Based Fire Protection systems-General Guidelines Water as natural medium is used most widely and effectively in fighting fire. The fire water system should be able to deliver a minimum of 520 to 940kpa hydrant pressure at full rated demand. The fire protection is normally sized to be capable of providing the largest calculated flow rate required for any single fire area within the facility. The actual design can be determined by providing 4.1 to 20.4 liters/min/m^2 of water to the fire area based...

... Fire Protection through Management of Negligence Yonder et al (218) s that prescribed burning is being continuously viewed as a useful but risky tool for land management and conversation. Consequently, they explain that common law aiming at fire management is predicated on negligence rules. According to the European Forest Institute (21), the knowledge about when, where and the reason why fires start is crucial in ensuring appropriate fire management and policy. The Institute argues that capability to comprehend and predict patterns of fire ignition is necessary in helping decision makers enhance fire prevention, detection and optimize the allocation of fire fighting resources. Presently about 95% percent of the fires in Europe...

..., including adjacent restaurants. While the tragic nature of the MGM Grand Fire cannot be downplayed, it served as a silver lining behind the dark cloud of the accident. Particularly, the MGM Grand Fire accident helped people grasp the danger of smoke inhalation as something as dangerous as the actual flames, if not more. This is because, as many as seventy-five died from carbon dioxide poisoning and smoke inhalation. Section 1: Fire Protection Systems Required By Regulations for the Facility and Their Status at the Time of the Event Before the MGM Grand Fire accident, it was required that all commercial buildings should have fire sprinklers installed. It is for this reason that the constructor, Orvin Engineering Company made...

... a prominent possible reason for collateral damage of both life and finances. These structures pose an equal threat to the neighboring structures as well. The only reason that designer didn’t previously considered it as a potential threat was that occurrence of these events are very less. But detailed studies after the WTC event have shown immense levels of flaws in the fire protection systems of tall buildings. The recent examples of fires resulting into complete collapse are the WTC 1, 2 and 7. Then the complete collapse of Apartment Block in St. Petersburg, Russia in June 3.2002, then Jackson Street apartments in Hamilton, Ontario, Canada in Feb 8,2002.
