I have been most successful using a high quality clear packaging tape 
such as that produced by 3M. (Although I am not sure what brand is 
available in Thailand.)  Make sure that the tape completely covers the 
label and wraps around the container, sealing the tape onto the tape, so 
that moisture cannot get under the ends of the tape.  This tape is not 
totally waterproof, but it should stand up in a humid atmosphere.  I 
have bottles for solutions that I have used for workshops for over ten 
years, rinsing and refilling them for each new workshop.

I know that funds may be limited, but it would be best to buy the 
smallest containers of chemicals that will fulfill the teachers' needs 
for six months or no more than one academic year.  The moisture and the 
mold not only affects the labels, but it also affects the chemicals.

Identifying unlabeled chemical will be a problem, but if they were used 
in a school (teaching) environment, then there is a high probability 
that very little will be highly hazardous.  You will need to confirm 
that with the teachers to find out what experiments they have been doing 
with their classes.

Again, lack of funds probably limits the teachers from obtaining a 
library of safety and disposal manuals. The most cost effective solution 
is to obtain catalogs from Flinn Scientific Inc. in Batavia, IL.  If the 
storage area is arranged by chemical families, as recommended in the 
Flinn Scientific Inc. catalog, even if labels do degrade, there will be 
some idea of the chemical family the reagent belongs to. They also have 
a "Mystery Substance Identification Procedure" that must be requested 
directly from them.  Although Flinn does not ship any chemicals or 
equipment outside the U.S., you should be able to get copies of their 
catalog if you will cover their shipping cost. If, for any reason, Flinn 
does not want to send you catalogs or the mystery substance procedure, 
have one of your colleagues in the U.S. request them and have them mail 
you the safety and disposal section of the catalog to reduce the weight 
of the mailing package.

  Subject: [DCHAS-L] Request for Advice on Chemical Hygiene

  I am in Thailand and the day after I arrived I ran a one day workshop 
on Information and Communication Technologies as the fourth day of a 
five day nation wide workshop for high school teachers.  I included a 
section on MSDS and Chemical Hygiene, and on the following day I was 
given written questions by the "adjun" (teachers).  Although only a 
minor part of my workshop was on chemical hygiene, every question but 
one dealt with either chemical hygiene issues or green chemistry.
  It appears that in this humid land (full of black mold) there is a 
propensity for labels to disintegrate off bottles in school stock rooms, 
and I was asked what to do.  So, I am asking if anyone has any web based 
(or other) protocols for dealing with unlabeled containers that I could 
share.  I would really appreciate any input as these are great people 
whom I believe have far greater problems than we do when it come to 
chemical hygiene issues and they do care.
  I really appreciate any input and help.
