Ordinary water is used in most fire sprinkler systems.
Most fire sprinkler systems are connected directly to the same water you get from the fire hydrant, which is also often the source for drinking water as well.

For each fire and material exist a specific fire-extinguishing method.
You would find the proper extinguishing media for material involved in a fire in section IV of the Material Safey Data Sheet. This section is labeled as Fire and Explosion Data.
Carbon monoxide is flammable so is not used in fire extinguishing systems. The carbon dioxide that is used in extinguishers can be deadly to humans as it displaces oxygen that a fire needs to burn, and humans need to breathe.
fire and explosion hazard data
A Class D fire extinguisher is recommended for extinguishing a metal fire.
You would find it in the fire and explosion hazard data section.
A Class A fire extinguisher is recommended for extinguishing wood fires.
A Class D fire extinguisher is suitable for extinguishing fires involving magnesium.
HCFC 123 is the raw base material use to produce a halogeanated, safe/effective and environment friendly fire extinguishing chemical agent called "halotron I". It was introduce in early 1990's to replace the "banned" fire extinguishing agents like, Halon 1211 and BCF's, which were found to have a severe ozone depleting potentials. In contrast, hcfc 123 base fire extinguishing agents has a near zero ozone depletion potentials.
Sand can smother a fire by cutting off its oxygen supply, which is necessary for combustion. By pouring sand on a fire, it helps to reduce the flames and cool down the burning material, eventually extinguishing the fire. Sand is often used as a fire extinguishing agent for certain types of fires, such as chemical or metal fires, where water may be ineffective or even dangerous.
Blanketing of fire refers to the method of extinguishing a fire by covering it with a material that deprives it of oxygen, thereby smothering the flames. This technique can involve using fire blankets, foam, or other materials to create a barrier between the fire and the surrounding air. It is particularly effective for small, contained fires, such as grease fires or fires in confined spaces, where traditional extinguishing methods may not be suitable.
