Our church furnace uses heating oil. Do we need carbon monoxide detectors?
No you can't disable the fire alarm system. Some states make it mandatory for large buildings to have them. The only thing i can think of is an expensive solution. You can bring to the schools attention of automatic ones instead of manual.
System software is the program(s) that keeps your system in order and allow you to easily run other useful programs. Windows and Linux are examples. Office software is what you use to actually do/create stuff. Word, Excel, Powerpoint, Access are examples of office software. They run within the system software.
Fire is a rapid oxidation process releasing light and heat. You need 3 parts of a fire triangle to make fire. Heat, fuel and oxidizer (usually air). If you break the triangle you break the chain reaction and the fire goes out. Use of water is most common. Water actually cools the substance burning to a point it stops putting out flammable vapors. It is the vapors that actually burn causing destruction of the object. Water does not put out fire by removing oxygen. It is used because it is usually plentiful and available. Flammable liquids like gasoline are best extinguished by a smothering chemical like a dry powder extinguisher or special foams that smother the fire. The problem with gasoline is it puts out its vapors at a temperature as low as about -38 degrees F. As soon as the smothering blanket breaks it is putting out vapors that can reach an ignition source. Electrical equipment is best extinguished by making sure the power is off then attacking the fire with what you normally would use, like water or chemicals. There are some agencies like NASA that have developed special systems that use inert cryogenics like liquid nitrogen to protect rockets, etc.
