Dave,

There is a technical guide, FEMA 412 - Installing Seismic Restraints for Mechanical Equipment that is intended to minimize earthquake damage caused by unanchored equipment in buildings.  It does not cover bracing/supports for stacked storage drums but if you need some backup to support your argument that something is needed, this publication might help.  It looks like the closest equipment condition to yours that is covered is 'tanks and gas cylinders' but these are not stacked.  

I think this publication is free by contacting the FEMA Distribution Center.  The phone number on the inside cover of my copy is 800-480-2520.

Hello all,
 
Does anyone who does industrial work know if there is some provision/exception for seismic bracing and anchorage of storage drums (700# each) that are stacked on a pallet, stacked several layers high?  We're doing a peer review for a client that is planning something like this but without any bracing of any kind.  Of course, I'm told "everyone's doing it this way" but it sure seems precarious, as well as a building code violation.
 
Just "picking some brains" here.
 
Thanks,
