<br />
<br />
There are four main methods to disinfect SARS-CoV-2 the virus that causes COVID-19.<br />
<br />
<ol style="text-align: left;">
<li>Time: The virus eventually no longer will be viable after a period of time. This depends on several things including the <a href="http://sustainablemycology.blogspot.com/2020/04/how-long-to-coronaviruses-live-on.html" target="_blank">surface type</a>, the temperature, and relative humidity. </li>
<li>Ultraviolet light (UV-C) also known as UVGI (<a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2789813/" target="_blank">Ultraviolet Germicidal Irradiation</a>) at 254 nm works to alter the RNA of the SARS-CoV-2.</li>
<li>Vaporized Hydrogen Peroxide </li>
<li>Temperature. Elevated temperatures reduce the viability of the virus. </li>
</ol>

<div>
Decontamination of respirators was effective at 70 degrees Celsius for 60 minutes. These elevated temperatures may cause damage to respirator components. </div>
<div>
<br />
<a href="https://stanfordmedicine.app.box.com/v/covid19-PPE-1-2" target="_blank">Stanford Medicine</a> has done multiple studies decontaminating respirators with UV-C and heat. In there study they found repeated heating of masks with hot air at 75C for 20 cycles did not damage a respirator. An 8 W UVGI (254 nm) for 30 minutes for 10 cycles did not damage the respirator.<br />
<br />
As I reviewed the 3M website masks appeared to have different temperature tolerances. </div>

Many places of employment are working through plans to reopen while minimizing transmission of SARS cov 2 the virus that causes COVID-19. The following is a list of guidances primarily from the CDC about opening businesses, schools and Universities.
