sammutusvedestä

Sammutusvesi, known in English as firefighting water or fire extinguishing water, refers to the water used in extinguishing fires. Its primary function is to cool burning materials below their ignition temperature, thereby stopping or slowing the combustion process. Sammutusvesi can be sourced from a variety of places, including public water mains, fire hydrants, natural bodies of water such as lakes and rivers, and dedicated water tanks within buildings or at fire stations.

The effectiveness of sammutusvesi depends on several factors, including the type of fire, the amount of water applied, and the method of application. Water is particularly effective on Class A fires, which involve ordinary combustible materials like wood, paper, and textiles, by cooling them down. However, it can be ineffective or even dangerous on Class B fires (flammable liquids) and Class C fires (electrical fires). Specialized extinguishing agents are often required for these types of fires.

In many jurisdictions, regulations are in place regarding the availability and accessibility of sammutusvesi to ensure adequate firefighting capabilities. This can include requirements for fire hydrant spacing, water pressure, and the maintenance of water supply systems. The management and allocation of sammutusvesi are critical components of fire safety planning and emergency response.
