R290 Research

I am in the process of building my own direct die evap fridge system. Being as interested as i am, i researched many aspects of building a fridge system. One of the area's i researched heavily was refridgerants. I became quite interested in R290 after reading about the good results and ease of use. The flammability issue concerned me aswell, so i did some math. If all 1.5 -2 Liquid Oz of R290 were to leak out of the system into my room with the dimentions of 10' x 10' x 8' there would be absolutely no volitility risk. Infact it would take around 30Oz of R290 to have what is considered a volitile concentration (BTW, 2% mix is minimum volitile amount). If you would like i can post the set of conversions and equations i did to come to this conclusion (additionally, 2 science teachers at my school checked over my work, its right). Would love to hear some more info on refridgerants though.
