The Mailscreen Suspicious Mail Isolation System was conceived and developed to handle suspicious mail from the point of discovery through to a first responders testing facility. This system provides an airtight method to isolate, contain, and safely examine suspicious mail and packages. MAILSCREEN provides a safe method to isolate and remove a mail threat from the premises with minimal disruption. Employee safety in the workplace is important. Letter mail threats are on the rise. Minimizing the risk is a reasonable measure to protect employees and assets.
