Question – Virkon-S Dwell Time and Post Rinse Requirement Does the PWS require a specific dwell/contact time for the 1% Virkon-S solution after application? Additionally, is a post-application rinse required, or is the process limited to applying the solution and allowing it to air dry? This has a direct impact on labor time, water usage, and wastewater volume.

Answer:

Applied as a liquid (1% solution) Can be done using the SKUMIX 20 also Mildly CORROSIVE in 1% solution. Contractor must rinse vehicle off when finished, especially soft metals (aluminum & copper) Creates large amounts of wastewater that must be disposed of per local regulations & requirements requires 10 minutes contact time and air dry per manufacture label, then rinse. A 1% solution must also be used during the 10 minute contact to keep the surface wet via misting or other application.

Question – Equipment Condition Upon Delivery The PWS states the Army will deliver equipment pre-cleaned and free of dirt and debris prior to Virkon-S application. Can the Government confirm that all 50 pieces of equipment will arrive at the wash site in that condition? If equipment requires pressure washing or pre-cleaning prior to disinfectant application, would that constitute additional scope outside the current PWS?

Answer:

Yes, all equipment will be located close to the AGWASH station prior to the application.

UTARNG will pressure wash/ pre-clean all the equipment before sanitizing.
