ENS 5583511 April 2022 17:20:00The following information was provided by the state of Colorado via email: Static Eliminator Model P-2021 reported as lost by new tenant of building previously occupied by Service King. Service King ended a lease agreement with the owner and was noted on Service King's registration that the static eliminator was surrendered as property of the building per lease agreement and they were not allowed in the building to retrieve the unit. After connecting and corresponding with the current tenants' (Classic Collision) manager he informed (the CO Department of Health) when they moved into the building everything had been removed except for a spray booth. He did look for the device but it was not found. Isotope: Po-210 Manufacturer: NRD, LLC.
