Thanks. ken hercenberg Senior Member Username: khercenberg Post Number: 880 Registered: 12-2006 Posted on Friday, February 27, 2015 - 10:03 am:    It needs to be a designed system of concrete substrate with suitable continuous curb that will contain the volume anticipated. We used to use polysulfide resinous membranes until the quality of those membranes became suspect. I've been told not to use epoxy systems. Depending on anticipated chemicals being contained, you may be able to use one of the newer generation polyurethanes. If memory serves, polyurea membranes may work better but I'd check with the manufacturers. In any case, it's a simple resinous floor with integral base spec once you figure out the right membrane to use. Robert E.

I have used multiple different types of prefab, assembled curb and absorptive pillow systems. Just Google "ups battery spill containment" and you'll find a plethora of solutions. Here are two that I have used: - http://www.sbsbattery.com/products-services/by-product/battery-spill-containment-systems.html - https://www.cdtechno.com/product/spillcontain/spillproduct.html This one looks pretty robust too: http://alpinepowersystems.com/Products-Services/Backup-Power/Backup-Power-Products/Safety-Equipment/Spill-Containment-Systems/Flooded-Battery-Containment/Enviroguard-Eagle-System.aspx Mark Gilligan SE, Senior Member Username: mark_gilligan Post Number: 716 Registered: 10-2007 Posted on Friday, February 27, 2015 - 12:38 pm:    Ask the electrical engineer if sealed batteries would not eliminate the need for the containment system. These batteries also reduce the concerns related to explosive gasses. Such batteries can be shipped without special care being taken.

There is a specific section in the UBC (slightly embellished in the Fire Code) that deals with this. You have to calculate a certain percentage of acid, even with sealed batteries. I have seen the wisdom on this, where I had a project that had a bank of batteries explode upon initial energization before the project opened. All the protective measures worked as advertised.
