    I have an older warehouse being converted to an public assembly arena. Does anything need to be done with the sprinkler system?

    I was told it would be used as boxing rink? Seems strange but I was asked if any work needed to be done. I don't think so as far as the sprinkler system goes but I am pretty sure the fire alarm system will need some work but I know enough about fire alarms to be dangerous.

    I have an older warehouse being converted to an public assembly arena. Does anything need to be done with the sprinkler system?

    The total building is 80,000 sq ft. Maybe I am wrong but the way I read it is quick response sprinklers are only required if the design is for a light hazard occupancy which, at a density of .25/3,000+500 hose it is not. As far as the occupant load I would leave that up to the architect of...

    I have an older warehouse being converted to an public assembly arena. Does anything need to be done with the sprinkler system?

    An older warehouse about 30 years old equipped with wet K=8.0 SR uprights on a system designed for baled cotton storage having a density of 0.25 gpm over 3000 sq ft with 500 hose. I believe it is just fine just as it is and even though it is a light hazard occupancy not having QR sprinklers...

    fire water demand

    In my opinion, and just my opinion, a fire sprinkler designer should have nothing to do with calculating fire flows because they are not related EXCEPT if a building has sprinklers there is a percentage reduction allowed. It is also my understanding that the method to calculate fire flows can...

    fire water demand

    Travis, This is sort of a rural project where we have a 6" city water main where a dedicated 6" line. The local fire official has approved the fire flow submitted by a licensed professional engineer so I am good to go.

    fire water demand

    In my opinion a fire sprinkler contractor, or designer regardless of his experience, has no business attempting to calculate "fire flows". How do you work this one? Its a series of condo's where the design is NFPA #13R in the units and NFPA #13 in the parking garage designed to a OH1. Design...

    fire water demand

    I am not qualified to answer this question but here goes anyway from the way I understand it to be. What matters the size of the building and if the building/property has sprinklers. If the building has sprinklers the fire flow might be 1,000 gpm if if the building is not sprinkled the fire...

    fire water demand

    I hold a NICET IV in fire sprinkler layout with 50 years experience. While I know what fire flow is and means I would NEVER do the calculations because it isn't my job. The responsibility of calculating fire flows is the job of the registered architect, licensed civil engineer or professional...

    Automatic Fill Valves for Sprinkler Tanks

    To be clear the tank is the sole supply to the fire sprinklers. And yes, the fill valves do supply the sprinklers but I do not believe the fill valves are required to be UL/FM approved. So far I haven't seen one that is UL/FM. The 48,000 sq ft will have three systems each covering...

    Automatic Fill Valves for Sprinkler Tanks

    I have a cold storage warehouse with a double interlocked preaction system where I plan to use a water storage tank and fire pump. Pump will be rated at 1,500 or2,000 gpm. Flow test results of the city watermain show 68 psi static, 42 psi residual @ 993 gpm. 20 psi @1,400 gpm. 500gpm hose...

    Question about whether a system is NFPA 13 or NFPA 13R

    First off it is NEVER my call to decide whether a system is to be designed per NFPA #13 OR 13R. That call is 100% the call of the project registered architect of record and nobody else. So I am looking at a two story project where there three offices with a residential area designed per NFPA...

    Flow test or fire pump test

    I agree with Travis and the actual fire pump test results are more accurate than calculating from a hydrant. I've done this a good number of times in four different states and never had a problem with any AHJ or insurance company.

    Milliken Fire Loss 1995

    I think it had a lot to do with the design of the overhead sprinkler. NFPA has never addressed rolled carpet storage and the only way to cover it is to go to FM Global. Data Sheet 8-30 Storage of Carpets. I have dealt with rolled carpet storage with the FM Global criteria and to say it is...

    FM Global and Baffle Requirements Separating Standard Response from Storage (ESFR) Sprinklers

    I want to thank everyone for their comments and pointers. I spent about four days going over the FM Data Sheets a number of time and I think I finally figured it out. Draft curtains is not something we run into every day. Thanks again.

    FM Global and Baffle Requirements Separating Standard Response from Storage (ESFR) Sprinklers

    Yes, very common but the one thing I am not fully informed on is the FM Global requirement for a aisle.
