    Fire Sprinkler Tank

    I am not a tank expert, however I would agree with MGXFP. The IFC and NFPA 13 point you to NFPA 22.

    Hi need help to how get better in reviewing fire code plans

    Section 106 of the International Fire Code provides a list of documents that should be required for construction plans review.

    Fire protection issues for battery

    Here are a few codes that I would recommend for your research: -- NFPA 1:52 - also refers the user to NFPA 855. -- IBC 907.2.23 - requires automatic smoke detection -- IFC 1207.5.5 - requires 1 of 3 options for fire suppression

    Hazard Classification

    I would concur with sprinklerdesigner2, if the height limitations are met, then this should be classified as an ordinary hazard, group 2.

    NFPA 13-2016 - In-Rack Sprinkler Water Demand

    Chapter 17 applies specifically to rack storage of plastic and rubber commodities. Whereas, 23.4.5 applies to hydraulic calculations for other in-rack systems.

    Lightning protection for standalone tank

    There are no "mandated" requirements for lightning protection. However, for your tank installation a hazard analysis should be conducted. Where the analysis indicates that lightning would be a potential ignition source then system should be installed.

    Does NFPA 25 need a rewrite?

    NFPA 25 is not an installation or design standard. So when a change is noted (25:4.1.6), that should be a signal to the inspector that this system may need to be referred to NFPA 13 for installation and desing updates or follow-up.

    Does the separation between the rooms meet the requirements of IBC 509.1 and 3005.4?

    temporary sprinklers in Museum Exhibits

    It seems like several other questions may need to be answered. Could a total flood special hazards suppression application be used? Does NFPA 241 apply to this temporary installation? How does the installation of this affect the buildings permanent system?

    Fire Pump Bypass Code

    This section of NFPA 1 seems like it would only apply to valves on the backflow prevention device...which seems to make sense.

    Having to do with Draft Curtains and ESFR Systems

    You may want to take a look at section 14.2.11.1 where the distances are from the obstruction, not just the ceiling.

    Surveying Advice

    A great tool that I use for ensuring code compliance and looking up code reference info is UpCodes. They have free and functional code access to the IBC, the IFC, NFPA 13, NFPA 101.

    NFPA 13R and domestic water allowance. Am I doing this correctly?

    The IFC 903.3.5.2 just states a requirement for the domestic demand to be added to the sprinkler demand.

    does a UPS room need a Clean agent protection as per NFPA?

    I am not sure of a specified/required protection system type. The NEC does have an informational note to see NFPA 75 for fire protection of IT equipment areas.
