Services – Covid-19 Sanitation Solutions

The Pandemic: COVID-19

  • COVID-19, the disease caused by the SARS-CoV-2 virus, has been declared a pandemic by the World Health Organization
  • It has halted or slowed economic activity around the world
  • Research evidence shows that coronaviruses can persist on surfaces for up to 9 days (Kampf 2020)
  • SARS-CoV-2 can remain viable (van Doremaien 2020)
    • In aerosols for > 3 hours
    • On plastic, stainless steel, copper and cardboard for up to 72 hours
  • Transmission is person to person and from touching surfaces with virus particles

The Challenge to the Workplace

  • Essential workplaces like fuel refineries, power plants, pharmaceutical plants and emergency services must keep operating
  • Staff keep coming to work, as they must
  • Common areas and workplaces can become contaminated by asymptomatic, presymptomatic or mildly ill workers
  • Virus particles can persist for days on surfaces and in the air
  • Healthy individuals can become infected through contact with these surfaces
  • How can we protect the workplace?

Ozone Gas Deactivates Coronavirus and Other Enveloped Viruses

DAF_Fig.4
  • Multiple research studies show that ozone gas can destroy coronavirus particles on surfaces (Sato 1990; Hudson 2009)
  • Ozone gas can destroy enveloped viruses (including coronaviruses), non-enveloped viruses, bacteria and fungi.

Ozone Gas Can Also Deactivate Coronavirus in Aerosol

Ozone Gas for Control of Coronavirus

  • Ozone gas can permeate every space in a room
  • Research has achieved 2-3 log10 decreases with 20ppm O3 or more and 120 minutes of treatment
  • Time under treatment is more important than O3 concentration
  • Results in deactivation of virus on surfaces, droplets and aerosol
  • Effectiveness is dramatically elevated by humidity
  • However, O3 is harmful to human health and regulated
    • OSHA and NIOSH standard (no more than 0.10 ppm ave. over 8 hrs) and CARB (no more than 0.070 ave. over 8 hours) safe levels

Dylan Rebel: Specifications

  • High capacity ozone generator
  • ATi F-12 ozone gas detecting system with audible and visible alarm system
  • Yokogawa digital recorder
  • Automatic temperature/humidity controller
  • Charcoal/maganese dioxide scrubber system
  • Fully automated

Rebel: Part of an Integrated Infection Control Strategy

  • Minimize risk after identification of a symptomatic employee
    • Treat all areas where they spent time
    • Get a fresh start for the facility
  • Deploy between shifts to minimize infection between groups
    • Asymptomatic carriers could infect people between shifts
  • Treat vehicles between crews
  • General abatement: regularly treat high-traffic areas
  • Emergency services
    • Treat police cars and ambulances between runs
  • Should be used as part of a comprehensive strategy with surface cleaning of high touch areas
