How water can be modified by additives to improve fire-fighting performance?
Additives are used in fighting fires because some classes of fires do not respond well when plain water is used to try and extinguish them. In fact, in some classes of fire, water actually makes things worse. The best example of this are Class B fires (Flammable Liquids like Gas and Oil).The 3 things needed for fire combustion to sustain itself are Heat, Oxygen, and Fuel (the Fire Triangle). Removal of any one element in the triangle will stop combustion. The aim of all firefighting additives is to remove one or more of those elements. Since it is difficult or impossible in many cases to remove the source fueling the fire, most additives are focused on removing heat and/or oxygen from the fire to halt combustion.While there are many water additives, the most well-known example is AFFF.Aqueous Film Forming Foams (AFFF) is awater based foam that is used on Class B (flammable liguid) fires. It's commonly used in airport firefighting vehicles as fuel fires are very difficult to extinguish. The foam expands rapidly when it hits the air, coats the surface of the fuel causing the fire, thus cutting off oxygen. It also cools it, thus taking away heat.Alcohol Resistant Aqueous Film Forming Foams(AR-AFFF)These are other types of foam that are used on alcohol type fires

What is CMR cable?
CMR cable is Communications Riser cable. It is used in risers or shafts from floor to floor and only a riser or plenum (CMP) cable may be used for that purpose. Though CMP can be used in lieu of CMR, you cannot use CMR in a plenum space. CMR and CMP are fire resistance classifications. CM is for general purpose that may be used elsewhere not requiring special fire code considerations.

How can baking powder be used to safely extinguish a grease fire?
Baking powder can be used to extinguish a grease fire by smothering the flames. When baking powder is sprinkled on the fire, it releases carbon dioxide gas, which helps to suffocate the flames by displacing oxygen. This method is safe because baking powder is non-toxic and does not produce harmful fumes when used to put out a grease fire.
