After a series of incidents in which antifreeze ignited after sprinklers deployed during a fire, NFPA investigated and began issuing new guidelines for its use in 2010. QRFS explains the current status of using antifreeze in fire protection systems, as well as alternatives for freeze protection.
This article breaks down the maintenance testing requirements for existing standpipe systems defined in NFPA 25: Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems. Our goal is to aggregate and contextualize this code for contractors and building owners.
This installment of a continuing series covers required acceptance testing for standpipe systems and the National Fire Protection Association (NFPA) standards that correspond with it.
This article examines the major individual components of standpipe systems, along with their installation, inspection, and maintenance requirements. Our aim is to simplify this guidance for both contractors and building owners.
This article provides an overview of the different types and classes of standpipe systems, as well as explains when they are required according to NFPA 14, the International Fire Code, and the International Building Code.
