Why is cyanuric triazide environmental friendly and less toxic?

This is the first line on [Wikipedia](https://en.wikipedia.org/wiki/Cyanuric_triazide):



> 
> Cyanuric triazide ($\ce{C3N12}$ or $\ce{(NCN3)3}$) is described as an *environmentally friendly, low toxicity,* and organic primary explosive with a detonation velocity of about $\pu{7300 m/s}$, and ignition temperature at $\pu{205 °C}$

While [it is written in the general WP article that "some" organic azides are classified as highly explosive and toxic](https://en.wikipedia.org/wiki/Organic_azide) (and citing the article in ref.), I want to know what determines its toxicity and why cyanuric triazide is less toxic?


Organic azides are heat and shock sensitive compounds and can detonate explosively to produce smaller azides which are definitely toxic along with hydrogen azide which has toxicity similar to hydrogen cyanide and there are guidelines to handle them ([here](https://www.ehs.ucsb.edu/sites/default/files/docs/ls/factsheets/Azides_FS26.pdf) and [here](http://ccc.chem.pitt.edu/wipf/SOPs/SafeHandlingofAzides.pdf)). Cyanuric triazide is a organic azide so why is it less toxic?
