ABSTRACT

Coffee Break Training: Automatic Sprinklers: Antifreeze System Expansion Chambers   [open pdf - 0B]

"This past winter's frigid and snowy weather served as a reminder that some sprinkler systems may be installed with antifreeze solutions to protect the pipe from cold temperatures. Antifreeze systems often are used for isolated portions of sprinkler systems where the expense and maintenance of a dry-pipe valve is undesirable. Antifreeze systems, though, have their own special set of conditions that must be in accordance with National Fire Protection Association (NFPA) 13, 'Standard for the Installation of Sprinkler Systems'. Perhaps most importantly, a temporary interim amendment to NFPA 13 prohibits the use of antifreeze within the dwelling unit portions of a sprinkler system."
