Don,
Actually these days Virkon is considered by far the best sanitizing agent around.. Its non toxic and has the highest range of bacteria/virus ect that it can kill..

It was originally an agriculture product, but is now available (officially) for human use..

from th CDF report
"

The products Sanizide Plus, Confidence Plus and Advance TBE have been suggested as safe for use under hyperbaric conditions [5], however, Quaternary Ammonium Compounds (QAC’s) do not meet the efficacy requirements for open water diving and CUMA/CCDA use as they are ineffective against non-enveloped viruses [26, 35] and QAC’s are known to be easily inactivated by detergents, organic matter and hard water [26, 40]."



The product Bi-Arrest 2 was also suggested as safe for hyperbaric conditions [5], however, the Phenolic component in Bi-Arrest 2 is considered a possible carcinogen [75] and consequently, human health may be at risk when dealing with this product. This product is also ineffective against non-enveloped viruses [26] and thus it does not meet the efficacy requirement for CUMA/CCDA use.

Virkon S

is considered a very efficient and effective broad spectrum disinfectant, proving its bactericidal, virucidal (against enveloped and non-enveloped viruses), fungicidal and tuberculocidal capabilities through multiple studies [23-25, 27-30, 61-71]. Virkon S is

considered a non-irritant at its working concentration of 1% [17, 18, 60], there are no acute effects to inhalation [20], exposure to product components are not associated with a risk of occupational asthma [19] and exposure has not resulted in toxic effects to animals [28]. The product has no vapour phase and is not inactivated by detergents or hard water [26], and if the product is used as prescribed with the preventive preparation precautions there are no significant health risks.
