Methods of abating, extinguishing and/or preventing Class B fires comprising applying a hydrogel comprising a biopolymeric thickening agent and a non-biopolymeric thickening agent to the Class B fire are described.

Exemplary embodiments of the present disclosure relate to preventive protection against fire, including forest fires. The embodiments include one or any combination of a flame-retardant substance, a flame-retardant composition, a flame-retardant fabric and a fire protection device comprising the same, to obtain different levels of protection. An exemplary flame-retardant substance can be configured for application to objects to be protected, and is obtained by a chemical reaction according to the formula [1]: M.sub.2(CO.sub.3).sub.x+n SiO.sub.2.fwdarw.M.sub.2O.sub.x.n SiO.sub.2+x CO.sub.2, wherein x=1, 2 and/or 3 and n is an integer between 1 and 10. The flame-retardant composition can include an exemplary flame-retardant substance in combination with a clay. An exemplary flame-retardant fabric can be configured for covering objects to be protected against fire and includes at least one woven layer containing silica glass. The flame-retardant substance may be applied to the flame-retardant fabric.
