Decontamination
(continued)
6-2 Cryogenic Dual Shippers
While the generally accepted practice of using 10% chlorine bleach as a
disinfectant is still preferred, some viruses are resistant to this treatment
and require treatment with 30% chlorine bleach solutions. Prions (like
those associated with Mad Cow Disease) are not known to be killed even
with this treatment. At the production time of this manual, we are unaware
of any completely safe and practical method for their removal/destruction.
