Keep in mind that hydrogen is an interferent to CO detectors - so if
hydrogen is being used in your lab (i.e. fuel source for GCs) you will
have to determine quite quickly which issue you have when you have an
alarm - CO or H2.

Use an industrial grade detector - the residential types are not
intrinsically safe and would not pass OSHA electrical code for
laboratory use - too many potential flammables. We have been cited in
industry for using residential type items unless they are intrinsically
safe or double insulated, etc.

It seems we have more and more labs wanting to work with carbon monoxide
and
I'm wondering when you require a detector and what type. Where do you
draw
the line for requiring a detector? Do you allow residential detectors
for certain
processes? When do you require a detector be linked into a
communication
system for alarms, security, etc? Is this based upon quantity, the
process, all of
the above? The labs will have quantities ranging from 80-140 cubic feet
in a
single cylinder.
Thanks,
Matt
