[Histonet] RE: Lab humidity range

[Martha Ward]

We chose 10 - 90% as our range after reading what few instrument manuals even addressed the issue.   I can only wish we could get to 17% humidity here in NC.

We're prepping for a Big Inspection (I could tell you who but then I'd
have to enter the Witness Protection Program).  The Inspecting
Organization will want me to cite a range for HUMIDITY in the lab.
Because this not only hinges on our weather (we're in Monsoon Season
right now and the lab humidity is 47% as I write but is normally between
17-20%), but also MUST be based on any of the histology equipment that
may be affected by humidity in any way.   Realizing that we all work in
different "environments" and usually have little or no control over the
HVAC system, what did you decide upon as your HUMIDITY RANGE for the SOP
under which you operate?  If there are no specific equipment
requirements, I will be able to give a range of 0-100% without the
necessity for a Corrective Action Report.  If I am too specific and give
too narrow a range, I may end up filling out a Corrective Action Report
for days when I'm "out of range".  Please give me as much detail as you
are able, without being required to join me in hiding.  Your input will
be rewarded (don't ask).
