This episode of the Dope and Tape show is all about BlazeMaster fire sprinkler systems. They bring on Ryan, a national sales manager for BlazeMaster, to answer common questions and clear up misconceptions. Lainey Headed up marketing, product, sales, and innovation strategy for Lubrizol Advanced Material's fire protection segment, including BlazeMaster(R) CPVC piping systems and freezemaster(TM) Antifreeze. While incompatible plasticizers in some wires can affect CPVC, it's generally not a major issue unless the wire is tightly wound around the pipe. NFPA prohibits any wires touching sprinkler pipes regardless of material. Never dry fit CPVC. It's unsafe and can lead to leaks.While air testing is sometimes done in cold climates, it's officially discouraged due to safety concerns. If done, it should be at low pressure (15 psi) and with precautions. UV light can cause discoloration but doesn't significantly affect the pipe's performance once installed. BlazeMaster chars but doesn't burn, and the smoke it produces is no more toxic than burning wood. Use a tubing cutter on older CPVC or in cold weather to avoid cracking. Ratchet cutters are fine for new pipe in warm conditions. It's perfectly fine to use Sharpies on BlazeMaster pipe. BlazeMaster is used globally, with major markets in Canada, the UK, Australia, and parts of Latin America. BlazeMaster aims to make the system easier to use, potentially with new joining methods and expanded applications.
