> Warning! Silver azide and halogen azides are extremely hazardous and explosive. Such compounds should be handled with utmost care and only in very small quantities (<5 mmol). Appropriate safety precautions (blast screens, face shields, Kevlar gloves, soundproof earmuffs and protective leather clothing) are necessary. Make sure to eliminate static electricity before handling. It is also crucial to avoid friction and light exposure and prevent any contact with metals during sample handling to ensure safety.

That is, please do the synthesis in full armor, in the dark and don't touch anything more than strictly necessary.

Also wear ear protection, because it's still going to go bang.

I like the green energy twist in the intro too. "High-energy materials" is an euphemism chemists engaged in weapons research like to use. I went to some conference talks about high energy materials before, and research presented at those talks was always funded by various defence agencies. But maybe that's just a North American thing, this particular group only acknowledges funding from the innocuous Deutsche Forschungsgemeinschaft.
