Re: [UK] One minute, one degree

the ARA's competence in this particular matter. There have been, and
will be, other threads for that!)

We've discussed this once before (June last year, Mr Anton at the
lectern) but it looks rather like speculation, albeit well-informed. If
we're to embody it in our safety instructions (which is what I, as
club safety thingy, am trying to do) we need to find an authoritative
source of it.

Before I write to the ARA to ask, can someone point me to a reference?

The one minute, one degree rule was described thus in the RoSPA report (page
68) -

"Eton College and Dorney Lake were very proactive in their management of
water temperature and possible exposure to cold water. They operated a one
degree, one minute rule developed by Rowing Canada where a ratio of
temperature to survival in water was used to advise rowers and determine
response time for coaches and rescue craft."

.... and was recommended for general adoption in section 9.1.7.

However I have been unable to find any reference to it in the safety section
of the Rowing Canada website - even in their weather and cold water advice.
I also can't find it on the Dorney Lake website - which doesn't seem to give
any details of their safety regime.

I think it operates thus: At (say) 5 degrees C water temperature you assume
you have 5 minutes in which to rescue an immersed victim - so rowers and
safety launches shouldn't be more than 5 minutes apart from each other. At
6 degrees you have 6 minutes to rescue etc. I doubt it is very accurate as
there are lots of variables, but it is useful as a rule of thumb.

Perhaps Dorney Lake management might be able to help?
