 So back in March, we established our COVID-19 task force as a way to basically find ways to keep our firefighters safe and to distribute information throughout the department. In one of those meetings, we determined that we needed to safeguard our PPE supply and extend it as long as possible because we didn't know what the duration would be for COVID-19. In doing research, we found the best way to extend the life of our PPE, our N95s, would be to find a way to decontaminate it or clean it. So we began doing some research. We found several methods, but we found that UV would be the easiest and most cost-effective way for us moving forward as a department. In that research, we found out that there was a community member that was actually conducting very similar research and had gotten a lot further in the process than we did. So we made contact with that individual and we began working with them and we developed our UV decontamination system by working together with other city members of the department, as well as members of our community, including members of USC, a local health care facility, DHEC, and multiple others that all came to the table to help us get to the point where we're at now. Yeah, so the basic terms are we collected N95 from the field, that was used, but unsoiled, right? So it didn't come in contact with somebody who had COVID, wasn't coughed or sneezed on or any blood-borne pathogens placed onto it. We bring that N95 down to our facility. It goes in one side of the machine where it's treated with UV light for five minutes, comes out the other side of the machine, the back side we call the clean side, and then from there it gets rebagged. The bag is labeled with the employee's name in their location and it gets shipped back out to the employee once they arrive back on shift at their scheduled time and they can use that mask again. And we use those masks up to five times in order to stretch out our supply to get through this pandemic.
