The measurements were done by Bob Freeman visiting from the USDoE.  It was
great fun - he had been equipped with some carefully calibrated monitors.
They alarmed at two levels - the first for "Danger" and the second for "Get
out!" Of course at 1600ppm they started making very anxious noises - and
then he found that, while he had been coached on resetting at the lower
level, no-one had ever thought he would need to reset from the upper level.
For 24h he walked around with the instruments making banshee-like noises
until the information on resetting from the higher level reached him.
We couldn't credit it either, but all the checks we could do were positive -
those were the levels, and they lived!
