Coronavirus Decontamination via
Vaporized Hydrogen Peroxide
This is an active and changing list of documents.
"Our results indicate that aerosol and fomite transmission of HCoV-19 are plausible, as the virus can remain viable and infectious in aerosols for multiple hours and on surfaces up to days." Aerosol and surface stability of HCoV-19 (SARS-CoV-2) compared to SARS-CoV-1
"SARS-CoV-2 RNA was identified on a variety of surfaces in cabins of both symptomatic and asymptomatic infected passengers up to 17 days after cabins were vacated on the Diamond Princess but before disinfection procedures had been conducted." Public Health Responses to COVID-19 Outbreaks on Cruise Ships — Worldwide, February–March 2020
"Coronavirus or endemic human coronaviruses (HCoV) can persist on inanimate surfaces like metal, glass or plastic for up to 9 days, but can be efficiently inactivated by surface disinfection procedures with 62–71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite within 1 minute. As no specific therapies are available for SARS-CoV-2, early containment and prevention of further spread will be crucial to stop the ongoing outbreak and to control this novel infectious thread." Persistence of coronaviruses on inanimate surfaces and their inactivation with biocidal agents
Decontamination via Vaporized Hydrogen Peroxide
There is a lot of data regarding decontamination via vaporized hydrogen peroxide. It's all over the place in terms of what is tested and conditions required. A lot of what is covered is done via proprietary equipment and solutions. Below are some of the documents.
Destroying SARS-CoV-2 with H2O2 410± 83 ppm for 180 minutes. Vapor H2O2 sterilization as a decontamination method for the reuse of N95 respirators in the COVID-19 emergency
Vaporized Hydrogen Peroxide is registered by the U.S. Environmental Protection Agency as a sterilant, which the EPA defines as "a substance that destroys or eliminates all forms of microbial life in the inanimate environment, including all forms of vegetative bacteria, bacterial spores, fungi, fungal spores, and viruses"
"..exposed to HPV 127 ppm for 1h at room temperature in an isolator" "HPV disinfection resulted in complete inactivation of all viruses tested, characterized by >4 log(10) reduction in infectious particles for poliovirus, rotavirus, adenovirus and murine norovirus on stainless steel and framing panel carriers, and >2 log(10) reduction for influenza" Virucidal efficacy of hydrogen peroxide vapour disinfection.
"1000 ppm for 10 minutes" Assessment of N95 respirator decontamination and re-use for SARS-CoV-2
"Spraying "ionized" 7.8% hydrogen peroxide three times in a ‘to-and-fro’ manner at a distance of 24 inches for a total of appropriately 6 seconds on respirators kills influenza A" Disinfection of N95 respirators by ionized hydrogen peroxide during pandemic coronavirus disease 2019 (COVID-19) due to SARS-CoV-2
"12-minute continuous charge of aerosolized hydrogen peroxide (7% H2O2; Curoxide®) was followed by six(6) pulse charges over 30 minutes.""The Curis® system uses a solution of 7% hydrogen peroxide with a proprietary blend to create a fog of aerosolized liquid H2O2 and vapor with concentration between 80-150 ppm." Aerosolized Hydrogen Peroxide Decontaminationof N95 Respirators, with Fit-Testing and Virologic Confirmation of Suitability for Re-Use During the COVID-19 Pandemic
Decontamination via liquid hydrogen peroxide & More Information
This study shows that within less than 3 minutes, 4 Log10 (99.99%) can be reduce of this coronavirus (SARS) using a concentration of 5,000 ppm or 0.5% of Hydrogen Peroxide. Environmental survival and microbicide inactivation of coronaviruses
This study shows that a concentration of 0.5% of Hydrogen Peroxide during 1-minute exposure, is virucide against Human coronavirus 229E a surrogate for the SARS virus. This Virucide activity is quantified as more than 4 Log10 (99.99%) reduction of infectivity. Broad-spectrum microbicidal activity, toxicologic assessment, and materials compatibility of a new generation of accelerated hydrogen peroxide-based environmental surface disinfectant
Vaporized Hydrogen Peroxide is registered by the U.S. Environmental Protection Agency as a sterilant, which the EPA defines as "a substance that destroys or eliminates all forms of microbial life in the inanimate environment, including all forms of vegetative bacteria, bacterial spores, fungi, fungal spores, and viruses”.
