Causes of fire

Arc formation and extinction lakes place inside a sealed chamber, thus emitting no gases or vapours to the atmosphere, which may be a cause of fire hazard. They are the most appropriate choice for such areas... 

The most conuiion cause of fire accidents in process plants is equipment failure. Tliis is primarily a result of poor equipment maintenance or poor equipment layout and design. Maintenance perfonned according to a detailed and well structured schedule will significantly reduce tlie occurrence of fire accidents. Tlie second largest cause of fire accidents is ignorance of tlie properties of a specific chemical or chemical process. Proper training of employees will increase tlieir knowledge of tlie properties of a specific chemical and chemical process and can prevent many of tliese chemical fire accidents. 

Fire is the major insurable risk to property on land. Each industry, trade or manufacturing process has its own fire problems. There are, in addition, causes of fire which are found in all occupancies (e.g. arson, smoking, and misuse of electricity). With such a wide field, it is only possible to touch lightly on the many important aspects of the subject. 

Hot gases rise by thermal lift. Hence in the open air they will disperse. Within buildings this is a serious cause of fire escalation and toxic/asphyxiation hazards if smoke and hot gases are able to spread without restriction (or venting) to upper levels. A balanced flue can serve to effectively isolate a combustion process in a gas-fired appliance, but must be sound in construction and unrestricted to avoid leaks. 

Sparks, etc. Sparks from mechanical tools and equipment, hot ashes from smoking, unprotected extension lights, boilers and furnaces, backfire from gasoline engines, are all potential causes of fire. Smoking should be prohibited in areas where flammable liquids are stored or are used in the open. All equipment in such areas should be maintained in first class condition. Wherever possible, spark-proof or non-sparking tools and materials should be used... 

Which of the following was the most common cause of fires ... 

Electrostatic and Electrostatics. Electrostatic pertains to static electricity or electricity at rest. It can be produced by friction or atmospheric electricity. Electrostatics is the science of static electricity. Electrostatic discharges are frequent causes of fires and explosions. This problem is discussed under ELECTRICITY, EXTRANEOUS AND HAZARDS ASSOCIATED WITH IT Refs 1) Hackh sDict (1944), 301-L... 

Discovery of fire changed human life irreversibly. Civilization began when man learned to build a fire. Primitive man did not know the cause of fire. 

Many superstitions about fire arose out of ignorance of the cause of fire. 

The cause of fire was a mystery for many centuries. Lavoisier of France finally solved the mystery of fire towards the end of the 18th century. He conducted a number of experiments and concluded that fire was the result of a chemical reaction between a burning substance and oxygen. This marked the end of alchemy and the beginning of the modem period.

Boerhaave s introduction of the non-mechanical cause of fire into his chemistry caused some problems for his contemporaries. Edward Strother (1675-1737), Doctor of medicine of Utrecht and Fellow of the London College of Physicians, who also translated Boerhaave s kmenta chemiae into English could not accept that Boerhaave s system is not entirely mechanical. Strother added in a footnote ... 

One must distinguish between the causes of fires and the causes of fire deaths. The primary causes of residential fires have been shown to be heating and cooking. Lack of central heat and the incorrect use of portable space heaters are two of the reasons given for the high fire and death rate in the South. Heating... 

The most frequent causes of fires and explosions involving GPTRs are the breaks in joints and solders, of taps, the bad handling of an exothermic reaction... Some examples will help to better understand the problem.
