I am currently in the beginning stages of design for a 200,000 sqft warehouse which will be used for production and assembly of electric generators (picture the gas/diesel trailer-mounted generator you would see on a construction site but battery powered). There will be three separate areas where the batteries will be stored.
The overhead system will be an ESFR k-25.2 system.
The specs for the job are calling out a rated, freestanding, sprinklered canopy structure above the battery storage areas as an additional requirement to the overhead system which does make sense to me.
Is there anyone who has advice or experience with this type of commodity and coverage of it?
What code references should we be looking at, if any exist?
FM Global released a study on lithium ion batteries but from reading over it they were testing smaller power-tool-sized batteries and not large battery banks.
To my knowledge this is a relatively new hazard for the industry and the code requirements are having to play catch up. Again, any guidance would be appreciated.
