Biosecurity for Public

We are here to help protect the hundreds of billions of passengers that share public transport each year
It’s a regulatory, health, and operational efficiency problem.

According to the CDC, about 48 million people in the U.S. (1 in 6) get sick, 128,000 are hospitalized, and 3,000 die each year from foodborne diseases. The major shift from responding to foodborne illness to preventing it is captured in the FDA’s Food Safety Modernization Act (FSMA). The act also indirectly impacts the 30% of the one trillion dollars in global food wastage that is lost somewhere in the food supply chain.

Crops are invariably treated with pesticides and fungicides, and it is a major challenge to remove these without altering the taste, texture, or appearance of the food. In fact it has been found that a common disinfectant, sodium hypochlorite, reacts with them to create additional hazardous byproducts.

Even in a cold chain, pathogens are still able to reproduce and so it is critical to ensure the food and its container are sanitized, and the shipping container is also free from pathogens, both at the start of its journey as well as throughout its typically 1,500 mile journey which is the US average.

Ozone and UVC

O3D2 uses AI with both ozone and UVC light during scheduled maintenance to decontaminate all compartment surfaces, including upholstery. The ozone also penetrates inaccessible locations like air ducts and underneath seats.

Decontamination time
The cleaning cycle is entirely automated and lasts a few minutes depending on certain factors. O3D2 monitors progress until everything is decontaminated and then proceeds to convert the excess ozone back into oxygen so it is safe to resume operations.

Schedule a site survey to objectively determine the level of decontamination you can expect. We have seen results up to 99.99%.

Side effects
No harmful chemicals are used and no residues remain. The only side effect is to enrich the air with fresh oxygen.





How does O3D2 use AI?

O3D2 uses AI to continuously sense the environment and make instant decisions that result in cleaner outcomes, in less time, without damaging the assets its trying to keep clean in a careful balancing act.

How does O3D2 produce ozone?

It uses high-voltage electron ionization to split diatomic oxygen into ions, which combine with O2 to produce triatomic oxygen, O3. The process is more efficient with drier input air, and even better when coupled with an oxygen concentrator.

What kind of UV light does O3D2 produce?

It produces high-energy UVC light, in the 254-280 nm range of wavelengths which is known to disinfect

How does ozone decontaminate?

Triatomic oxygen is a highly reactive gas. Each molecule readily oxidizes various elements of organic material. For example, it cause bacterial membranes to rupture, rendering them inert. For viruses, ozone causes peroxidation of the infected cells and also damages the viral capsid.

Which pathogens can O3D2 destroy?

Bacteria, viruses, fungi, mold and spores. Each pathogen reacts differently to ozone and UVC, meaning different concentrations and contact time.

Is ozone safe?

Yes, it is FDA approved for use in decontamination with OSHA guidelines for concentrations and exposure time, and 0.1 ppm is considered safe for humans. O3D2 constantly monitors the air to assess when it is safe to re-enter.

What happens to the unspent ozone?

It naturally degrades back into regular oxygen. This can take minutes to hours depending on many factors including whether it is airborne or dissolved in water, temperature and humidity. For safety, O3D2 measures the concentration of ozone until it is safe. Catalytic destructors accelerate the process.

What are some examples of recalls?

Dec 2020, 8,492,832 lbs of Tyson frozen ready-to-eat chicken products due to potential listeria contamination (link)

Mar 2019, 78,164 lbs of Butterball’s turkey products due to possible Salmonella Schwarzengrund contamination (link)

2011, 33 died, 147 infected in 29 states from cantaloupes that were “contaminated in the farm’s packing house because of dirty water on the floor” and that “packing and storage facilities” helped to spread the listeria from Aug to Oct 2011 (link)

Anytime a bad guy or person of interest to law enforcement comes in here and their tag is read, it will notify our entire police department. We're trying to keep the bad guys out and protect our citizens.
We hope the cameras will just scare people from doing anything wrong, but if they do anything wrong, we then have evidence to go after them.
