Work with the facts on dry chemical extinguishers!
The 2002 NFPA 17: Standard for Dry Chemical Extinguishing Systems outlines minimum requirements for all functions concerning dry chemical extinguishing systems, from design to operation and recharging. Chapters in this vital Standard cover such topics as total flooding, local application, hand hose line, and engineered and pre-engineered systems.
Significant changes to this latest edition include revised requirements for the protection of common exhaust ducts and clarified language regarding equipment power shut-down upon operation of the extinguishing systems. (Softbound, 24 pp., 2002)
