So you observed in the video that undoing the release mechanism is a choice not a necessity. Removing the helmet is simply the two clips at the side. Done, flip off the front and perform CPR clear airway DRABC etc.
Removing the helmet with absolutely no chance of twisting or pulling on a compromised neck can also be achieved by removing two screws...pretty simply really... Even a paramedic could acomplish that if necessary.
I agree with the QR, Gulg, it may or may not be available to the EMTs but despite not knowing that...this design is eons in front of any other full face design when trying remove from an immobilized patient.
Not sure if it will be the be-all of helmet design in the future but is certainly the most revolutionary design I have seen in a helmet in the last 30 years.
Interesting to see that people's first reaction to anything unconventional is negative.
