    NPFA 30 - Warehouse Fire protection schemes A,B,C,D,E - What sets the scheme

    Plastic or metal IBCs? That's the big question. The Scheme is based on the liquid's classification, if the liquid water-miscible or not water-miscible, the container's material of construction and its volume. Scheme A-E are limited to rack storage. An IBC under NFPA 30 is not a Container...

    Fire rover

    It looks like a single application system. It's unclear if it is connected to a water supply and it probably needs electricity.

    Slope of work surface as per OSHA/NFPA/IBC

    The only provisions for a ramped walkway are in the International Building Code or the Life Safety Code and are limited to Means of Egress. I'm not aware of a provision for your described situation in the National Electrical Code but I will warn you I have limited experience with the NEC...

    Is a flexible hose (pipe) allowed as a fuel level indicator?

    The fuel level in a fire pump is gauged. This means one uses a sight glass, a liquid transmitter connected to Human/Machine interface, or a simple clock gauge based on the tank.

    Fire Sprinkler Tank

    Your client brought a high-risk fire hazard to a jurisdiction. Your responsibility, based on the local fire code, is to provide a reliable water supply. More than likely you will need to provide a static tank and water supply. I cannot help you unless you provide the building code governing...

    Calculation of Hold Time for Novec

    Does the pressure increase warrant a damper? In all of the clean agent systems I've reviewed, the pressures were very low, even in small enclosures.

    Microbrewery

    OH G2 because of the idle pallet storage. Be careful if the distillery performing canning operations. Automatic canning equipment commonly will assemble the palletized load. Part of this process involves inserting a 1/8 inch sheet of HDPE of PE film. An assembled pallet load can have > 15%...

    Two story building with mercantile first floor (no sprinklers) and sprinklers 13R on second floor

    What is the adopted building code in the jurisdiction? The answer is in the Building Code, not NFPA 13.

    Rack storage for Building Materials

    I would classify it as Cartoned Unexpanded Group A plastic unless test data demonstrated the heat release rate is consistent with similar Class III commodities.

    NFPA 13 maximum area protected per riser

    NFPA 13 was completely revised in the 2019 edition. So exactly what are you asking?

    runoff of firewater

    It depends. NFPA 30 requires a means of containment and diking from a petroleum storage tank containing Class I, II or III liquid. The 2021 International Fire Code and NFPA 400, in certain cases, requires the design of an outdoor secondary containment to contain a specified volume liquid based...

    NPFA 30 - Tank Mounted Dispensers Acceptable?

    Review Chapter 6. Nothing in the provisions prohibit the installation of a dispenser on top of the AST so long as it meets all of the NFPA 30A Chapter 4 provisions. Note that Section 4.3.6 only allows for openings at the top of the AST. Section 6.3.4 doesn't require require a remote dispenser...

    NPFA 30 - Tank Mounted Dispensers Acceptable?

    You're not using the correct standard. If the aboveground storage tank installation is for motor vehicle fuel dispensing, the design should be based on NFPA 30A.

    Original system installed in 1908 and owner wants to convert to residential 13R but I see problems

    Let us know how the internal inspection of the 113 year old pipe goes.[bigsmile] I appreciate the passion of the Historical commission members but you're correct about the issues and solution. Your client has a GA Fire Code issue and you're tasked with solving it. You may be able to leave the...
