I'm in Monona's camp on this one at first blush, if it Devarda's Alloy.  Be aware that this also masquerades as Devarda's Metal.  That may help expand your search?

Subject: [DCHAS-L] Devarda's Alloy

We recently acquired some Dacarda's Alloy and are being faced with whether or not it needs to be stored in a flammables cabinet. We have not yet received an MSDS from the Manufacturer, and even just the NFPA ratings seem to vary incredibly. (Yes we are absolutely looking at the rest of the MSDS, but this provides a quick overview of how differently it is being presented in the different sources.)

From Sigma Aldrich (available from their site, but I am unable to attach here):
NFPA Rating
Health hazard: 0
Fire: 3
Reactivity Hazard: 3

From ScienceLab MSDS™23683
Health: 3
Flammability: 1
Reactivity: 1
Specific hazard

From SIRI (not a source I would normally use, but is specifically listing the brand we have)
Health Rating: 0 - None
Flammability Rating: 1 - Slight
Reactivity Rating: 1 - Slight
Contact Rating: 0 - None

Can anyone shed any light on this particular materials' storage? It has caused some controversy here, and we would appreciate another perspective. Thank you!
