Is a blood-alcohol content of 2.29 dangerous?

As a blood alcohol concentration (by percentage) anywhere between 0.3-0.45 is considered increasingly lethal (with 0.45 being the lethal dose for most people) and 0.5 and above is certain to end life, a blood alcohol concentration of 2.29 would most likely have to be administered post-mortem as the subject would have been dead long before being capable of consuming enough alcohol to achieve this. Such a blood alcohol concentration is unlikely to be dangerous to the dead.
