Special Hazards Fire Suppression Systems Service

fire suppression system

Gaseous agent special hazard suppression systems are most often designed and installed to protect industrial equipment, process equipment, flammable liquid areas, clean environments and electronic equipment with an extremely high asset value, such as computer centers, data storage equipment, telecommunications equipment and other mission-critical equipment. Often, clean-agent systems are designed and installed to protect intangible assets, such as special software, down time, electronic transfer of assets and business interruption. It is imperative that these systems be installed and maintained in accordance with the guidelines of the National Fire Protection Association's Pamphlets 12, 12A, 2001 and others. Spears Fire & Safety Services’ certified technicians inspect, test and maintain fire suppression systems in accordance with the NFPA code requirements and the requirements of the authority having jurisdiction.
