You can access the video at: http://r744.com/web/assets/video/1234yf-vs-134a-fire.mp....

"According to Daimler, a blue flash fire appears after about two seconds, indicating that the R-1234yf is burning. Released by a remotely controlled valve in the refrigerant piping, it releases highly toxic substances before the fire is extinguished after 12 seconds.

Within this short time period the flamesí yellow color indicate that the fire has already spread to the plastic parts of the motor compartment, and the front windshield is corroded by the aggressive acid.

Daimler said that similar tests carried out with the current R-134a refrigerant did not result in ignition."
