I’d consider a four gas meter with a Photo
ionization (PID) channel in the equipment similar to a RAE systems product.
This equipment is a little expensive but well worth the price!

We had a “strange,
noxious odor” today in one of our fourth floor classrooms. The fourth
floor is where, among other things, there are A&P and cadaver labs and
biology classrooms with plants and pets and various other things that might
cause an odor, so they came to me, the chemistry teacher, because I was
lecturing on that floor, to inquire if I was making any noxious odors. I
mentioned that the bio lab was having trouble keeping their pet mice in their
cage, and sure enough, one of the mice had died in the classroom where the odor
was. I thought it was funny that their first thought is to check to see
if the chemist is making any fumes in an ordinary classroom. (I never use
smelly chemicals anywhere except the chem lab. That‘s what fume hoods are
for.)

This is
to address detection of CO, a lethal but odorless gas, with a low occupational
exposure limit.
DO NOT depend in CO detectors designed for residential use. They have a
slow response time, and an alarm threshold much greater than the OSHA workplace
limits. For those laboratories/shops that use CO (even if appropriate
ventilation is in place and personnel are well trained), it is prudent to have
an industrial CO-specific detector near the most likely route(a) of
escape. Lapel detectors are available for those who work with CO in a
hood or glove bag/box.
We experienced an adverse exposure to CO because the researchers were depending
on a residential detector.

Subject: [DCHAS-L] Portable Gas
Detectors
Hello Everyone,
I recently became the first CHO at my institution and joined the ACS DCHAS.
The LISTSERV has already provided me with valuable information. Our
institution is small and Chemistry is a "service" area to the rest of
the College (including a small Biology Program). Last week we had a
report from a staff member of a "strong and ugly odor" coming from a chemistry
lab. The staff member called Public Safety and they called me. It turns
out that the lab tech had just prepared reagents containing cyclohexane.
After the incident was determined to be "minor", the Public
Safety Chief told me that his office used to have a Portable Gas Detector, but
that said detector was lost. Can any of you recommend such a device? Brand?
Detectors?
Thanks in advance for any assistance,
Mario
