Initial import request used an SDS from American Elements, which listed no special storage requirements and specified the material was not hazardous. Target was ultimately purchased from KJLC, which listed many more hazards, since they just listed the hazards of the individual elements, rather than testing the alloy; storage in an inert environment was also listed as necessary. After discussion with Matthew Moneck (Executive Manager, Claire & John Bertucci Nanotechnology Laboratory, Electrical & Computer Engineering, Carnegie Mellon University) via the MIT Labnetwork, he mentioned that storage away from oxygen is important: they took the approach of storing it on the bottom of the sputtering chamber, wrapped in foil, when not in use. After discussion with Michael Hume and Glenn Elaschuk, we will go with this approach also. As for hazards, they treated it as they would other Ni or Co alloys: respiratory and skin sensitisation hazards come from the Co.
