Conservation of spray paint cans

The Museum of the City of New York has recently been offered a
collection of old spray-paint cans that were used by NYC graffiti
writers.  Does anyone out there have any ideas what
conservation/safety risks these cans (Rustoleum, Krylon, Red Devil,
etc.) might present or what we could do to safely store them for the
long-term?  Any suggestions would be much appreciated,
