Fire events in residential, commercial or industrial buildings are always associated with pollutant formation. Primarily, air pollutants whose composition and quantity depends on the fire conditions and materials involved in the fire are generated.
Besides carbon dioxide (CO2), carbon monoxide (CO), nitrous gases (NOx), sulfur dioxide (SO2), hydrogen sulfide (H2S), chlorine (Cl2), hydrogen chloride (HCl or hydrochloric acid), hydrogen bromide (HBr), hydrogen cyanide (HCN or hydrocyanic acid), ammonia (NH3) and phosgene (COCl2) can also be generated.

Especially in the presence of plastics, wood preservatives, electrical components and devices, dioxins and furans (polychlorinated dibenzodioxins and furans (PCDD/F) as well as polybrominated dibenzodioxins and furans (PCDD / F)) can occur.
Burning organic materials emit polycyclic aromatic hydrocarbons (PAH). These are attached to the soot particles.
The pollutants can enter the sewage system or seep into the ground in dissolved form with extinguishing water and precipitation. If this is the case they pose a threat to soil and groundwater. Chlorides contained in extinguishing water can attack construction components (in particular concrete).
Besides fire pollutants, construction components or storage materials containing common hazardous substances (e.g. asbestos, artificial mineral fibers (AMF), chemicals) in the building must also be taken into account.

Measures and activities related to fire damage restoration are subject to the VdS guideline 2357. It represents the generally accepted rule of technology. With the exception of small fires, an expert who has the expertise in accordance with DGUV Regulation 101-004 (formerly BGR 128) must therefore be consulted in case of fire damage rehabilitation. The expertise according to DGUV Regulation 101-004 also covers the expertise according to TRGS 524. The rehabilitation companies involved must also have this expertise.
Our services to you include:
- Survey of Building Construction (basis for the further operating steps)
