                TVI Corporation Second Quarter Sales Increase 51%
                         Operating Income Increases 36%

GLENN  DALE,  MD -- August  5, 2004 -- TVI  Corporation  (OTC BB:  TVIN),  today
announced that sales increased 51% to $10.2 million for the second quarter ended
June 30, 2004, compared to $6.8 million for the same period last year. Operating
income  increased  36% to $2.7 million for the three months ended June 30, 2004,
from $2.0 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.

Sales increased 51% to $18.8 million for the first six months of 2004,  compared
to $12.4 million for the same period in 2003.  Operating income increased 39% to
$5.3 million for the first half of 2004, from $3.8 million for the first half of
2003.

Net income  increased  40% to $1.7  million or $0.060 per basic share and $0.057
per diluted  share for the second  quarter of 2004,  compared to $1.2 million or
$0.045 per basic  share and $0.042 per  diluted  share for the same  period last
year.  Net income  increased  44% to $3.4  million or $0.120 per basic share and
$0.113 per diluted share for the six month period ended June 30, 2004,  compared
to $2.4  million or $0.087 per basic share and $0.080 per diluted  share for the
same period last year.

Gross  margins  (gross  profit as a  percentage  of net sales)  were 48% for the
second quarter of 2004,  compared to 50% for the first half of 2004, 51% for the
second  quarter of 2003 and 52% for the full year of 2003. The slight decline in
gross  margins  was due  primarily  to a change  in  allocation  of  facilities,
occupancy and insurance  costs,  which  increased  overhead costs. In 2003 these
costs were charged to General and Administrative expenses.

Operating  margins were 27% for the second quarter of 2004,  compared to 28% for
the first half of 2004,  30% for the second quarter of 2003 and 30% for the full
year of 2003.  The  operating  margin  decline was due  primarily  to  increased
expenditures  on  product  development  and the  integration  of CAPA into TVI's
operations.

TVI  Corporation  continues  to improve its cash  position  and operate  with no
long-term  debt.  During the first half of the year the Company  generated  $3.6
million in cash flow from operations.  The Company invested $1.6 million of this
in fixed and intangible  assets.  Cash increased $2.7 million for the first half
of 2004. Cash at June 30, 2004 was $10.3 million.




"TVI plans to use its  significant  cash  position and cash from  operations  to
expand into  complimentary  areas of our growing market  segments,"  stated Rick
Priddy, CEO of TVI Corporation. "We have a considerable customer base throughout
the world and understand the need for first responder systems and have developed
products to meet the requirements of hospitals'  in-patient  isolation and surge
capacity.  We have already seen results from our CAPA  acquisition and it is our
mission to grow as a world-class  homeland  security  systems  provider  through
leadership  in developing  and  supplying  rapidly  deployable  first  responder
systems for hospitals, fire departments, police and military."





Orders  received,  but not  shipped  through  the last week of July  2004,  were
approximately $7 million.  The Homeland  Security budget for 2004 is expected to
grow in the 25% to 35% range and TVI expects  sales growth in this year to match
the industry's growth rate.

"We  continue  to see large  follow-on  orders for  decontamination  systems and
hospital related shelters from existing  customers," Priddy stated. "We are also
encouraged from the number of agencies that have standardized on our platform in
recent months. Many of these  standardizations  are accompanied by small initial
orders,  however,  they set the  stage for  larger  orders  for  decon  systems,
hospital surge capacity shelters and patient isolation systems."

The Company will host a conference call at 5:00 PM (EDT) today,  August 5, 2004,
to discuss the Company's second quarter results. The call will be hosted by Rick
Priddy. Investors can listen to the call by dialing (877) 692-2592 (Domestic) or
