From TN Office of EMS:
There have been several questions regarding KKK specifications and ambulance builds over the past several days. It is our understanding that KKK standards will be updated and go into effect on July 1, 2015. The new KKK standards call for the updated restraint system. As such, any ambulance purchased after July 1, 2015 will require the new restraint system. Units purchased, but not delivered, before July 1, 2015 will still fall under the KKK specifications in use at the time the truck was purchased and/or contracted. I have included a link to the KKK specifications below. Pages 26 and 27 will provide information on cot mounts. Also, please note that remounted trucks will fall under the KKK specifications that were in use at the time the box was built and will not fall under these new specs. I hope this helps to clear the issue. If you have any questions, concerns or comments, please let me know and I will be happy to assist.
