IANARS but I play one on the internet. Depending on exactly where it came from on the rocket and which rocket it came from there could be smaller tanks embedded within larger tanks and fuel lines that are still pressurized behind closed valves. That wouldn’t be known until they confirmed its origin. Finally the content of what could be pressurized is some pretty toxic and carcinogenic chemicals like nitrogen tetroxide or monomethyl hydrazine.
