Background In general, fire protection refers to all measures that prevent the development and spread of a fire (i.e., fire and smoke) (i.e., preventive fire protection or fire protection), and are capable of rescuing people and animals as well as effectively extinguishing a fire (i.e., defensive fire protection). Fire fighting is multi-level and complex and is therefore common in many areas of daily life. Thus, for example, in germany, fire requirements may be found in a number of legal regulations, such as federal fire department laws and building codes, and many other laws, regulations, and guidelines. As mentioned above, a distinction is generally made in particular between preventive fire protection on the one hand and defensive fire protection on the other hand. Preventive fire protection refers to all preventive measures taken to contain the development and spread of a fire through structural, technical and organizational measures, and t
