FOR IMMEDIATE RELEASE

                TVI Corporation First Quarter Sales Increase 52%

                         Operating Income Increases 41%

GLENN  DALE,  MD -- April 28,  2004 -- TVI  Corporation  (OTC BB:  TVIN),  today
announced  that sales  increased 52% to $8.6 million for the quarter ended March
31,  2004,  compared to $5.7  million  for the same period last year.  Operating
income  increased 41% to $2.6 million for the three months ended March 31, 2004,
from $1.8 million for the same period last year.  TVI  Corporation  is a leading
supplier of rapid deployment  shelters and  chemical/biological  decontamination
systems for the military, public health, and first response agencies.

Net  income for the first  quarter of 2004 was $1.6  million or $0.056 per basic
share and $0.053 per diluted share, compared to $1.1 million or $0.042 per basic
share and $0.038 per diluted share for the same period last year.

Gross margins (gross profit as a percentage of net sales) were 53% for the first
quarter of 2004,  compared to 52% for the full year 2003. Gross margins declined
from 56% in the first  quarter of 2003 due to  increased  material  and overhead
costs.  Part  of  the  increase  in  overhead  was a  change  in  allocation  of
facilities,  occupancy and insurance  costs.  In the first quarter of 2003 these
costs were charged to General and Administrative expenses.

Operating  margins were 30% for the first quarter 2004,  compared to 30% for the
full year of 2003. Compared to the first quarter of 2003, operating margins were
lower by two percentage  points.  The operating margin decline was due primarily
to increased expenditures on product development.

We do not expect gross margins or operating  margins to change  dramatically for
the full year of 2004.

TVI Corporation  continues to improve its cash position and operate with no bank
debt. During the first quarter,  the Company generated $1.3 million in cash flow
from operations. Cash at March 31, 2004 was $8.9 million.

At the end of the first quarter,  TVI's backlog was  approximately  $8.2 million
that included orders received from the State of West Virginia, the Italian Civil
Protection  Department,  Emergency  Management  Australia and the  Department of
Defense. TVI currently has a backlog of approximately $6.7 million. The Homeland
Security  budget  for 2004 is  expected  to grow in the 25% to 35%  range and we
expect our sales growth in this period to match the industry's growth rate.

"During the first quarter,  major customers placed significant  follow-on orders
for  decontamination  systems and hospital surge capacity shelters," stated Rick
Priddy,  CEO of TVI Corporation.  "We expect this trend to continue as state and
national  agencies  determine the best way to prepare for a catastrophic  event.
Accordingly,  international  sales have  increased  dramatically  this year with
orders from the United Kingdom, Australia, and Italy."

"As the nuclear,  biological,  and chemical terror threat increases,  our growth
strategy  is to  continue to sell  decontamination  systems to new and  existing
customers, cross sell our infection control products and hospital surge capacity
shelters, while expanding our international marketing efforts," Priddy stated.
