So theoretically you could be at 90+ ppm for ever and it

The OSHA PEL-TWA is 50 ppm

ps
EPA says 12.5 - 15.4 ppm ave for 8 hours is just plain unhealthy.

So I'd want a detector that would let me know at an ave of 10 ppm a
t 8 hours or provides digital read out of peak levels on demand down to 10 
ppm.
