Fire
A fire is a exothermic chemical process in which fuel gets ignited in presence of oxygen and gave out heat and light. A fire is an exothermic reaction because it gives out heat and light in the surrounding. It occurs in 4 stages that are Incipient, Smouldering, Growth and at last it gets decay. In first stage that is incipient in this stage when heat, oxygen and fuel combines and evolve in chemical reaction in this stage a person can't able to see the heat and smoke then after incipient stage. Smouldering Stage occurs in this stage a person or a fire fighter can only see the smoke as the fuel burn slowly and only smoke can be visible and no flame will be seen. Smoke generated from fire has many toxic gases such as carbon monoxide, aldehydes, acid gases, sulfur dioxide, nitrogen oxides and many more, Due to release of these toxic gases from smoke generated by fire people loss their life more in comparison to fire. Due to generation of carbon monoxide from smoke it get dissolved in
History and types of sprinkler
In 1812 the first sprinkler system was installed in United kingdom at Theater royal, Drury lane. At that time these systems were Designed in such that the cylindrical airtight reservoir contains 95,000 litres which was fed by 250mm water main which supplies water to all parts of theater. Types of Sprinkler 1. Perforated type sprinkler system- This type of system were used in textile mills in new England as a fire protection but the difficulty was that they were not automatic these sprinkler system were used in 1852 to 1885.After that Philip W. Pratt of Abington, Massachusetts started experimenting for automatic sprinkler in around 1860 after that in 1872 he patented this system. 2. Automatic sprinkler System- Henry S. Parmalee of New Haven, Connecticut, is considered the inventor of the first practical automatic sprinkler head .After that parmalee improved the system which was patented by Philip W. Pratt. In 1874 the piano factory which was owned by Henry S. Parmalee installed it
Gas Explosion
It may be a deflagration or detonation. it totally depend on the flame speed which can be greater than or less than the speed of sound in the unburned fuel air mixture. In deflagration and detonation Peak pressure and the form of pressure time loading are fundamentally different . In detonation Peak pressure generated are at least twice as large as those of deflagration. Pressures generated in gas or dust deflagrations in buildings are often of the order of 1 psig because most building structures will fail at pressures of that order of magnitude
