It seems that Nanny has got herself into a bit of a muddle over safety in swimming pools.
Specifically, she is confused about the use of goggles.
On the one had Nanny believes that they prevent eye irritation, from the chlorine in the water. However, she has issues with regard to the drowning risk posed by the goggles.
Yes, drowning risk.
It seems that Nanny's chums in Gloucester Local Education Authority are advising head teachers to ban children from wearing swimming goggles on safety grounds.
They are worried that the goggles present a "drowning hazard" to other pupils. The LEA fears that teachers could be distracted by having to adjust goggle straps on one child and, in so doing, fail to notice another child drowning.
Let's not even mention the risks of the elastic snapping, and causing a nasty little bruise!
Precisely how many children drown each year because of goggle adjustments?
Another example of rules being made, without any form of statistical data to back them up.
