Correct me if I'm wrong but the NFPA , consider a Water reactive material one that will initiate combustion when mixed with water such as Sodium, Is it listed in the CFPA specifically by name or Cas number? Applying water to Conc. H2SO4 will result in the evolution of vast amounts of heat , but the material itself will not ignite under any conditions. Once you have diluted the acid to 20% the heat generated from further dilution is negligible. ---------- From: Dan Brandler To: [log in to unmask] Subject: [TN] Sulfuric Acid - Maximum allowed by Fire Code. Date: Tuesday, November 30, 1999 7:37PM Hello Technetters, Does anyone know the maximum amount of concentrated sulfuric acid (96%) allowed on the permises (single site) by the California Fire Code? What are the exemptions, if any? How about dilute (15%-20%) sulfuric acid. Is it still considered to be "water reactive" and subject to the same regulations? Has anyone had a problem with compliance of enforcement of these regulations? I would appreciate knowing how you handled it? Please advise. Thank You. Dan Brandler. ############################################################## TechNet Mail List provided as a free service by IPC using LISTSERV 1.8c ############################################################## To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TECHNET <your full name> To unsubscribe: SIGNOFF TECHNET ############################################################## Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information.
