Fire Suppression System
Fire suppression systems are used to extinguish, control, or in some cases, entirely prevent fires from spreading or occurring. Fire suppression systems have an incredibly large variety of applications, and as such, there are many different types of suppression systems for different applications being used today. Of these, there are some that are still in use but are no longer legal to manufacture and produce, such as Halon 1301. Suppression systems Fire suppression systems are governed by the codes under the National Fire Protection Association, also known as the NFPA. This organization writes codes, regulations, and recommendations on the proper installation and maintenance of these fire suppression systems. Likewise, the NFPA also lists criteria that must be met for the requirements of certain types of fire suppression systems. Types * Fire sprinkler systems ** Wet pipes ***This is the most common sprinkler system. Once the bulb filled with water inside of the pipe heat ...

Halomethane
Halomethane compounds are derivatives of methane () with one or more of the hydrogen atoms replaced with halogen atoms (Fluorine, F, Chlorine, Cl, Bromine, Br, or Iodine, I). Halomethanes are both naturally occurring, especially in marine environments, and human-made, most notably as refrigerants, solvents, propellants, and fumigants. Many, including the chlorofluorocarbons, have attracted wide attention because they become active when exposed to ultraviolet light found at high altitudes and destroy the Earth's protective ozone layer. Structure and properties Like methane itself, halomethanes are tetrahedral molecules. The halogen atoms differ greatly in size and charge from hydrogen and from each other. Consequently, most halomethanes deviate from the perfect tetrahedral symmetry of methane.Günter Siegemund, Werner Schwertfeger, Andrew Feiring, Bruce Smart, Fred Behr, Herward Vogel, Blaine McKusick “Fluorine Compounds, Organic” Ullmann's Encyclopedia of Industrial Chemistry, ...
