    FM Global Property Loss Prevention Data Sheets 8-9 - Table 8. Ceiling-Level Protection Guidelines

    I don't do a lot of HPS anymore, but I will see if I can answer some of your questions; As noted, the green demands are 250 hose because these are essentially "suppression mode" designs. IE, FM does not use the term ESFR anymore, its now either a storage, or non storage mode sprinkler per DS...

    FM 200

    Travis, you have a link to your website on every post, which gives your email, company name, and phone number. Am I missing something?

    IBC Sprinkler Height

    FM did some full scale fire burn test about 10 years ago. The sprinklers don't get the heat they need to operate at these high ceiling heights.

    Auto Parts Storage

    Matthew, if they are metal parts, like screws, washers, etc, then I can see Class I. But when I read "auto parts", I see plastics. However, I don't mean to second guess you on a project I had nothing to do with, so I retract my earlier statement. Here is my concern in general - we live in a...

    Class Commodity of Computer Accessories.

    Fm has a different take. Once that plastic gets going, it will burn as well as the other plastics. They got rid of the various plastic classifications, and now call it either plastic, cartoned, expanded, etc. But I realize code and NFPA are a different animal. I have used A and B in the past...

    Auto Parts Storage

    Class I is not correct. I have called it plastic in the projects I dealt with.

    Hanging from drywall ceiling, brand new method

    Peanuts, real peanuts in bags.

    If that is a polystyrene insulation it will burn like a Roman candle, and the commodity classification will be the least of their concerns because the sprinklers will likely be overwhelmed, regardless of the density you spec for the racks. As noted, not in your SOW, but a potentially serious issue.

    Exhausts fan in warehouse.

    CDA, you are making comments about an area that you are not familiar with. PR- google, FM Global, then Data Sheets. Register for the free, public version, and you will have access to all of them. There are specific criteria for exhaust vents, air flow velocities, protection criteria, etc.

    NFPA 850

    There is only one location within FM where things are tested. It is a long process and will cost money. Google FM Global research and approvals to learn more.

    Preaction System with Nitrogen supervision instead of a compressor

    Are you saying the N2 in a sprinkler system and a few bottles that feed it will cause life safety issues? some of the largest corporations In the US use this method. you may want to re think this. for a typical, large volume building, the emission of nitrogen should not be a problem.

    Minimum water supply required for NFPA 30 project

    If it's storage of ignitable liquids, Data Sheet 7-29 will have most of the details. There is a free, public version of the doc. dispensing is covered in 7-32. Also, One of the biggest differences between IFC/NFPA and FM is the max allowable quantity concept is not followed. A 55 gal drum of...

    Minimum water supply required for NFPA 30 project

    Good to hear Travis. We try to spend a lot of time and dilligence at FM to get these projects right..the first time.

    Surveying Existing High Deck Systems?

    A few ideas: Climb the roof ladder to the top rung, then look at the pipe or pipe couplings. Look for a mezzanine, but I am sure you do that. Get the sprinkler contractors name of the riser that installed it. Not always there, but you can ask for a set of as builts. They will likely charge you.

    Activating a wet sprinkler fire suppresion system that was dead for the past 2 years

    Trish, I appreciate your interest and questions, but be cautious asking detailed questions on an Internet forum. I think this site is helpful for more general queries. It sounds to me like you need to involve a sprinkler contractor and probably an FPE as well to walk that building with you and...
