"On February 21, 2008, the United States government destroyed the disabled spy satellite USA 193 with a sea-launched missile, reportedly due to the potential danger of a hydrazine release if it re-entered the Earth's atmosphere intact "
en.wikipedia.org... heres a link about that satellite with more details
Also recently there was that incident with that 'lost' russian satellite. The danger there again, was the hydrazine. After the two shuttle disasters they were issueing warnings saying if you found debris from them do not touch them and call authorities because of the potential contamination. So ya nothing unusual about them walking around like that.
