BS EN 15004-1:2019 pdf free.Fixed firefighting systems – Gas extinguishing systems.
The design, installation, service and maintenance of gaseous fire-extinguishing systems shall be performed by those competent in fire extinguishing system technology. Maintenance and installation shall only be done by qualified personnel and companies. The hazards against which these systems offer protection, and any limitations on their use, shall be contained in the system supplier’s design manual. Total flooding fire-extinguishing systems are used primarily for protection against hazards that are in enclosures or equipment that, in itself, includes an enclosure to contain the extinguishant. The following are typical of such hazards, but the list is not exhaustive: a) electrical and electronic hazards; b) telecommunications facilities; c) inflammable and combustible liquids and gases; d) other high-value assets. For the purposes of this document, the term “bar”shall be taken as “gauge”, unless otherwise indicated. Concentrations or quantities expressed in percentages (%) shall be taken as by volume, unless otherwise indicated.Global warming potential (GWP) and ozone depletion potential (ODP) values applicable to the gaseous extinguishing agents are detailed in EN 15004-2 to EN 15004-10.  NOTE GWP is a measure of how much a given mass of gas is estimated to contribute to global warming. The scale is a relative comparison on a mass basis where a clean agent is compared to carbon dioxide, which has a GWP equal to 1. ODP provides a relative comparison of the ability to react with ozone at altitudes within the stratosphere. ODP values are reported relative to the same mass of CFC-11, which has an ODP equal to 1. The intergovernmental panel on climate change (IPCC) and the Parties to the Montreal Protocol provide up to date environmental information on clean agent alternatives. Users of this part of EN 15004 are encouraged to review the information provided by those organizations to understand the significance of the environmental properties of the agents in this part of EN 15004.BS EN 15004-1 pdf download.
