I agree with the urgency of this short video. I am a retired paramedic with 26 years of professional experience, including dive and ice rescue. This physician, is right on on his assertions and proposed techniques. I have heard so many people say if you fall in the water (of Alaska anyhow) you can only survive 3 minutes… that could not be further from the truth… The key is to not drown! If you can keep your head above water, you can survive freezing water temperatures for an amazingly long period of time.
The inflatable PFD’s are a great idea when venturing out on questionable ice. The old sayign goes that a person could walk on about 2", while that may be true, is the ice 2" thick universally? My experience is no. There are many things that effect the ice thickness such as underwater upwellings, flowing water, animal activity underwater (beaver/muskrat) and even decaying vegetation. Even the sunlight can reflect off of the bottom in shallow water and decompose the ice formation from the bottom up.
