Wet chemical extinguishing agents, such as potassium acetate and potassium citrate, when sprayed on a grease fire, extinguish the fire by smothering and cooling. The wet chemical agent reacts with the hot grease and forms a layer of soap-like foam on the surface of the fat, which acts as an insulation between the hot grease and the atmosphere, preventing the escape of combustible vapors and oxygen supply.The wet chemical agent also absorbs heat from the grease and lowers its temperature below the ignition point12

According to NFPA 230: Standard for the Fire Protection of Storage, 2015 Edition, building codes should limit the size of an unsprinklered facility used for the processing and storage of Municipal Solid Waste (MSW) built of type V construction to 7,500 ft2 (697 m2). This is based on the assumption that the MSW has a heat release rate of 18,000 Btu/ft2-min (200 kW/m2) and a fire growth rate of 0.046 min-1.Type V construction is defined as a type of construction in which the structural elements, exterior walls, and interior walls are of any materials permitted by the code123

Computers and other information technology equipment are particularly susceptible to heat, steam, and combustion products, which can damage their sensitive components, cause data loss or corruption, and impair their functionality.Therefore, fire protection for IT equipment should consider the potential sources of heat, steam, and combustion products, such as electrical faults, flammable liquids, dust accumulation, water-based sprinklers, or smoke from adjacent areas, and implement appropriate measures to prevent, detect, and suppress fires, as well as to minimize the exposure of IT equipment to these hazards1234.References:Standard for the Fire Protection of Information Technology Equipment;Fire Protection of Computer Rooms—Legal Obligations and Best Practices - ISACA;Exploring Requirements for Information Technology Equipment;Demystifying IT room protection requirements - Consulting.
