In answer to your question, there
is an
OSHA standard, called “Hazard Communication,” that requires
chemical labeling and accessible safety data sheets, including ACGIH
TLVs. (OSHA
has proposed to strengthen by adopting a stricter and more
comprehensible global
system in use in
Art students are not employees so they are not covered by the standard. But since there are employees who work in the school – janitors, technicians, even the faculty itself – the labels and data sheets should be available.
I was involved in a similar situation some time ago. I reminded the school that there is a very active tort bar, and that if a student was injured by a material that the school knew was dangerous, and the school had withheld the information, they were looking at millions in legal fees and damages, not to mention losing accreditation. At that point they seemed to rediscover their conscience, and put a pretty good program in place.

Permissible limits
Chris, That's a good short list. But I'm
such an
idealist, I hope that on occasion a student asks: "If the
TLVs are
based only on health factors, what other factors are being used by OSHA
to set
PELs?"
And if those other factors are economic and feasibility factors, are
The same type of problem occurs in universities when faculty doesn't
fully
inform and train their students.
I recently visited a school that will remain nameless. The
EH&S
people are planning to finally start hazard communication training
program in
the art department after an incident--the usual reason they call
me. The
EH&S people, as usual, were not very familiar with conditions in art
and
suitably shocked when they saw them. But it was the comments of
the art
faculty that that email is about. They told the EH&S people
that they
must not train the students about the hazards or they might lose
enrollment.
So in schools, I guess we can add "keeping your enrollment high so
your
job is secure" as yet another factor that should be considered in
setting
exposure levels and providing training.

PEL = Permissible Exposure Limits (29 CFR 1910.1000)

ACGIH = American Conference of Governmental Industrial Hygienists
•Based on health factors only.
•TLV = Threshold Limit Value (8 hour TLV-TWA, TLV-STEL, TLV-C,

•BEI = Biological Exposure Indices (mg/l of body fluid to

in biological monitoring)
Here is a nice little summary I use in class. For worker safety it
always
better to use the lower thresholds but the OSHA thresholds are the
legally
enforceable ones.
OSHA (or state established) exposure limits are law:
•TWA = 8 hour time weighted average
•STEL = 15 minute Short Term Exposure Limit
•C = Ceiling Concentration must never be exceeded.
Other exposure limits are guidelines or BMPs:
