Conclusion: Byotrol Vs. Alcohol
Overview
Breathing apparatus is nearly always in close physical contact with the nose mouth and face.
Regular use results in transfer of bio-burden [bugs] from wearer to the mask and provides a nutrient source.
Left unchecked, the microbial flora on a mask will present a clear risk to the wearer Increases the likelihood of illness Likelihood of persistence of a
disease/malady
Masks and Human Health
Shock & awe! Hit ‘em hard
Hit ‘em fast Maybe
damage their ‘country’
Wait a bit Repeat
Current Strategy
Current Process
Clean it
Disinfect it
Rinse it
Air dry it5/23/2012 - Senior Airman Mark Rocamontes, 374th Operations Support Squadron aircrew flight equipment journeyman, inspects a MBU-12/P mask before sanitizing it at Yokota Air Base, Japan, May 21, 2012. Masks are inspected and sanitized every 30 days. (U.S. Air Force photo by Airman 1st Class Krystal M. Garrett)
Current cleaning process Relies on direct contact of the disinfectant with the
microbe. This requires a specified contact time in order to be
effective From a bugs point of view
Avoid the contact [By hiding under other bugs] Survive the contact times [Noro-virus needs 60
seconds wet contact with alcohol] Arrive after the cleaning has been done!
Cleaning as we do it now makes life easier for new microbes to move in. Another “bug benefit”
But From A ‘Bugs’ View?
Alcohol efficacy drops sharply as it goes below 60%, ‘failing to danger’ during the cleaning process. This is made worse if a large evaporative surface area is presented [i.e. if it is used as a wipe].
Alcohol Risk Factors [1]
Images 50 x and 500 x showing the typical large surface area for evaporation presented by a non woven wipe
Damage An organic solvent (Alcohol)
Can and will affect certain mask polymers that compose a typical mask causing swelling
More importantly damage/erosion of certain components changing the structure of the component making it more microbe friendly.
Alcohol Risk Factors [2]
According to the Association for Professionals in Infection Control and Epidemiology ( APIC) Eethyl alcohol and isopropyl alcohol are not effective in
sterilizing equipment and instruments They lack sporicidal activity Can’t penetrate protein-rich material
Isopropyl alcohol lacks the ability to kill hydrophilic viruses
For these reasons, alcohol is classified as an low- intermediate level disinfectant.
Activity of both alcohols, however, drops sharply when diluted below 60%.
APIC
Damage [1]
Smooth appearance of new/ v low use mask seal [Image at 250 x Mag using SEM]
Very Pitted and damaged areas found all over alcohol cleaned and used mask [Image at 250 x Mag using SEM]
Damage [2]
Damage to the mask caused by solvent application can be seen creating small and larger ‘pits’ which have a structure that is very attractive to microbial colonization
Killing germs and other microbes is easy.
Controlling them for prolonged periods is very hard!
Remove the problem Disinfectant
Change the conditions Anti-infectant!
Powerful, Long lasting but [to us!] gentle.
The Strategy of Byotrol
Protection Barrier
Broad-band biocide effects on virus, bacterial cells & spores, fungi and algae.
Inhibits the re-growth of biofilm for extended periods of time.
Unique properties is Residual/durable action Remains active even
after it dries Provides long- lasting
active protection for extended periods
Why Byotrol Technology?
The Differences That Gentle And Persistence Bring : Less Damage
Sections of new mask after 500 wipes with alcohol and after 500 wipes with Byotrol showing pitting damage with alcohol. Note Accelerated test shows very similar effect to the ‘used mask’ sections
Byotrol Alcohol
Using The Correct Wipe Material
Disinfectants applied by paper wipes will leave residues behind that can act at as ‘refuge’ for
microbes

Possible Military Application
All respiratory and above neck equipment subject to contact with the skin: Chem / Bio Masks and Hoods [Aircrew and Ground Crew]Lip Lights Visors NVGsFlash-Blindness Goggles Boom & Throat Mics
Distinct advantages over alcohol:1. Non-HAZMAT. Convenient shipping, storage, and handling2. More effective than alcohol3. Safe for aircrew and technicians4. Long lasting protection after its dry
Proven more effective though testing
Safe no hazardous materials
More PowerfulAbsolutely deadly to bacteria and viruses...Fast acting effect; powerful germ killing power – up to 99.99% of germs in 30 seconds.Broad-based efficacy across all microbial classes: bacteria, viruses, fungi, molds & algae.
Gentle
Harmless to individual aircrew …..Bleach is toxic and corrosive, alcohol can irritate skin.Byotrol’s structure allows for fewer chemicals, reassuring for you and your family.
Long-lasting
keeps working long after alcohol have stopped.Residual, durable, long-lasting protection from germs : hours, days, weeks, even months for certain formulations
