Thanks again. I was unable to find any forms in NFPA 25 and I don't have access to AFSA. In a message dated 10/2/2014 10:13:36 A.M. Eastern Daylight Time, dsm...@ci.oswego.or.us writes:
I have typically seen an applicable section related to internal pipe obstruction investigation on the service report that is used to identify if it was completed or not. If it's not completed, we request that it be completed. Often we see some type of unique form specifically related to the internal inspection that describes what was found and the areas inspected. There is information in the Annex of NFPA 25 that provides a generic form available for reporting the internal condition of sprinkler piping. This is one of those times where being a member of the trade group may allow you to obtain a clean copy of that form for use. There is also some additional explanatory material in the annex of NFPA 25 related to how much scale is considered okay or a problem.

I have one more question. Is there a specific form that needs to be completed after the inspection or do you just give a narrative of your findings?

It's suggested to vary the locations within the system each time. I'm not a fan of internal pipe cameras unless it's the type that can take pictures for documentation purposes. I've encouraged contractors in the past to document the locations that they inspect with several pictures identifying the room and other identifiable landmarks in the room/area before taking close up images of the pipes condition. It doesn't do anyone any good to have a picture if you don't have several images from further out proving where the picture was taken. > > As I can't post pictures directly of what one should be looking for, > take a look at slide #22 as an example at: > http://strategicfire.org/images/userfiles/files/Smith-ContractorEndors > ementProgram.pdf > > I understand that FM Global will make insureds Hydro-Pneumatically Flush their systems if considerable debris is identified. > > As for samples, it depends what you are looking for. There are a number of laboratories throughout the US that do water quality and corrosion testing. In lieu of recommending any one company over another, I'm sure a simple web search on fire sprinkler MIC corrosion will yield some results of companies that are qualified. There are some forensic metallurgical consulting firms that get involved with investigations of MIC, while there are some other firms that have solutions to minimize it. Truly depends on what you are looking for. It would be suggested to first identify what company you will use for testing any samples and then verifying with them how to collect, package and possibly ship the sample. > > Hope this helps..... > > David Smith | Deputy Fire Marshal > P 503.635.0378 | F 503.635.0376 > dsm...@ci.oswego.or.us > 300 B Avenue | PO BOX 369 Lake Oswego OR 97034 > > -----Original Message----- > From: Sprinklerforum > [mailto:sprinklerforum-boun...@lists.firesprinkler.org] On Behalf Of > djj8...@aol.com > Sent: Wednesday, October 01, 2014 11:56 AM > To: sprinklerforum@lists.firesprinkler.org > Subject: Question on internal exam of sprinkler piping > > I see that NFPA requires an internal exam of sprinkler piping every 5 years. Which parts of the system need to be inspected specifically? I see that video cameras inserted into the piping are allowed to conduct this inspection also. This seems as though this would be easier than taking sections of piping apart. Also, if some corrosion is found, what is to be done about it? > I see that sending samples out for testing is an option. Where would you send the samples for testing and specifically what is required to obtain these samples? > _______________________________________________ > Sprinklerforum mailing list > Sprinklerforum@lists.firesprinkler.org > http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkl > er.org PUBLIC RECORDS LAW DISCLOSURE This e-mail is a public record of > the City of Lake Oswego and is subject to public disclosure unless exempt from disclosure under Oregon Public Records Law.
