Good point, Bradley.  The firemen who inspected the lab recently wanted an 
NFPA fire diamond with "0,0,0" on the 600-gallon DI water tank, I can 
understand that.  Of course they don't care about the DI wash bottles on 
the bench (although they did notice the one that was labeled HIV - for the 
lab section).  
Our Chemical Hygiene Plan has a list of lab-specific acronyms and 
abbreviations right up front.  But that still doesn't really solve that 
shorthand labeling problem we see from time to time.  [But then everyone 
in the lab seems to know what a container that's labeled "128" is, right? 
(it's vesphene diluted down 1:128).]  Thanks to this discussion string, 
I'll be creating reagent-specific label templates for things we make up 
all the time - like the profiled hazardous waste streams.  It's a complex 
field folks.  (Hope you don't mind that I used a few undefined acronyms.)

Using Abbreviations should be dependent on several items, including hazard 
levels, and the amount of chemical.  For example, a small container with 
non hazardous chemicals used in a small laboratory could have an abbreviati
on.  If there is a gallon, or 55 gallons of the same chemical the 
container should have a full label.

teaching abbreviations in school seems to undermine the information given 
from the full chemical name.

stresses some of that.  Those who have not worn Level A or Level B might 
consider that others have and will continue to due so.  Bad labels, some 
of us might be invoked, whether needed or not.
