How much of an explosion? If the battery completely disintegrated, you
have metallic cadmium and cadmium hydroxide sprinkled around the place,
and possibly also compounds of cobalt and other fairly nasty stuff. If
it just vented without totally rupturing, there probably isn't much
toxic material around. Take a look at the recommended cleanup procedure
here <http://www.cornerstone-lsp.com/documents/msds/MFNCMSDS.pdf> - if
you have a shop vac with HEPA, use it.
Warning: The cadmium electrode is pyrophoric (may ignite spontaneously
in air). If the battery is ruptured, it is an ongoing fire hazard; it
may ignite by itself.
