Another alternative is to use Diphoterine(R), an amphoteric, polyvalent,
slightly hypertonic, non-irritant, non-wsensitizing, non-toxic, sterile,
ACTIVE skin decontamination solution whose reactions with both acids and
bases do not generate any significant exothermic heat releases. It has been
successfully used in European workplaces and laboratories for a number of
years, and is effective againts acids, bases, oxidizers, reducing agents,
solvents, irritants, etc.
More information is available on the manufacturer's website: www.prevor.com
(click on the British flag for the English version) which also contains
numerous peer-reviewed publications and major Congress Abstracts regtarding
this product.
