Furthermore, airtightness is also of great importance for fire protection of server rooms, archives and museums. In these areas, water damage is prevented by using dry risers in case of fire. We measure the gas density of these areas by utilizing our BlowerDoor (by fan) in order to investigate whether the 10 minute redress life condition of the extinguishing gas can be guaranteed.
By means of the BlowerDoor through the standing time of the extinguishing gas guidance means of the NFPA VdS be determined. From the standpoint of fire safety must secure spaces, especially spaces and server and storage of hazardous substances during an x-number of minutes (usually 10 minutes) are gas density
This section focuses on
To prevent and control of fire prevention and mitigation of accidents in fire prevention and limitation of personal damage from fire. Automatic extinguishing systems are part of the fire as described in the Health and Safety Act. The activation of extinguishing systems can endanger the health of persons who reside in the protected area.
For the technical design, the following nationally and internationally accepted guidelines and standards are applied, which most recently published version of force.
- NFPA 2001 Standard on ‘clean agent’ Fire Extinguishing Systems
- VdS 2380 Richtlinien für Feuerlöschanlagen mit nicht verflüssigten Inertgasen
- VdS 2381 Richtlinien für Feuerlöschanlagen mit halogenierten Kohlenwasserstoffen – Planung und Einbau
- VdS 2093 CO2 Feuerlöschanlagen ISO 6183 Fire protection equipment – CO2 Fire Extinguishing Systems
- NFPA 12 Standard on CO2 Extinguishing Systems
- NFPA 11 Standard for Low-, Medium- and High Expansion Foam Systems
- NFPA 2010 Standard for Fixed Aerosol Fire Extinguishing Systems
In addition to the safety regulations for extinguishing systems must also spaces in which the premises are located to meet certain requirements. This is to create an optimal safety for the people in those spaces. In the construction and the establishment or refurbishment of buildings one must take into account safety requirements directly related to the installation and use of fire extinguishing systems.
Space integrity ( ventilation, density, underpressure and overpressure equipment)
Upon entry into force of a hydrant system, the loss of extinguishing agent to adjacent areas to avoid. Access doors shall be self-closing and if necessary be fitted with sealing strips. When using carbon dioxide (CO2) extinguishing gas may not flow to other staffed premises or accumulate in low lying areas (crawl spaces, basements, tanks) which are from time to time people stop for such maintenance are required to enter those spaces. If this can not be guaranteed, it should be enclosed with a CO2 detection alarm to be placed. In order to avoid extinction reignition, a secure area so ‘close’ are made that the concentration of extinguishing agent for the state is maintained over time to the minimum protection required.
To ensure this is usually supplied with gas extinguishing a space density measurement (doorfantest) was performed. Here, the actual density of the room determined on the basis of an underpressure and overpressure test. Of these density measurement area must have a certificate issued by the installer to be, this density measurement area, after each adjustment of the architectural space to be repeated. Depending on the amount and type of fire-extinguishing medium in the space is vented, it is possible that a first underpressure, and then an overpressure in the space occurs.If it is positive or negative pressure is greater than the construction of the space allows, a pressure relief valve to be applied. These may consist of a grid, equipped with a valve used in over-or under pressure opens and then closes again automatically. This pressure relief valve is preferably directly to the outside air by blowing it off. If this is not possible, one in the placement of the valve into account the potential hazards that can arise if the room air, extinguishing gas or gases are blown. Furthermore, the protected area after extinguishing safely ventilated.
