GLENN DALE, Md.--(BUSINESS WIRE)--July 24, 2002

TVI Corporation (OTCBB:TVIN) reported today that the State of Massachusetts has selected TVI Mass Casualty Decontamination Systems for state-wide application of all decontamination systems.

The first two orders for 28 Decontamination Systems total more than $1,500,000.

The patented, state of the art TVI system was designed with the Massachusetts Emergency Management Agency (MEMA) to allow First Responders to rapidly decontaminate victims of a Weapons of Mass Destruction attack, such as a nuclear, biological, or chemical weapon. Massachusetts is one of the first states to develop a statewide program for the decontamination of its citizens.

"This award validates our ongoing design efforts to create innovative systems with the capabilities and functions that best serve the Homeland Defense needs. This unique decontamination system, developed with Massachusetts Department of Fire Services leaders, incorporates 50 separate pre-installed fabric shower nozzles. The pre-installed fabric shower nozzles (Pat.Pend.) and the Patented TVI one piece articulating frame shelter combine to create one of the most rapid deployable and rugged decontamination systems available. This represents a new direction for mass casualty decontamination." TVI CEO Richard Priddy stated.
