Two items of import on an otherwise informative video:
First, all soil, mud, etc. should be cleaned FIRST, before decontamination. The lab tests show that the organic materials can impede the effectiveness of the chemicals and/or high temperature procedures.
Second, when handling any of these chemicals, the person should protect their skin with the use of gloves (latex or equivalent) and eyes with goggles. Keep oneself safe!
