         ENVIRONMENTAL SAFEGUARDS ANNOUNCES JUDGMENT AGAINST SUBSIDIARY

HOUSTON, September 1, 2004 --- Environmental Safeguards, Inc. (ELSF:OB), parent
company of OnSite Technology L.L.C. ("OnSite"), announced today the return of a
judgment against OnSite in the amount of approximately $7.3 million plus
attorney's fees.  The judgment was the result of a lawsuit in the U.S. District
Court for the Southern District of Texas (Civil Action No. H-02-2624) with
Duratherm, Inc.

OnSite continues to believe that its operations do not infringe Duratherm's
patents and has been so advised by its legal counsel.  OnSite expects to file a
notice of appeal.  Any appeal of the judgment must be made to the Federal
Circuit Court of Appeals in Washington, D.C., and could take from six to nine
months or more before a final determination.  There can be no assurance,
however, that OnSite would prevail on appeal.


                 CAUTION CONCERNING FORWARD-LOOKING STATEMENTS:

This  release  contains  forward-looking  statements  concerning  OnSite's
expectations  of  an appeal as well as its operations and financial performance.
These  statements  reflect  the  Company's current expectations and are based on
information  currently  available.  They  rely  on  a  number of assumptions and
estimates,  which  could  be  inaccurate,  and  which  are  subject to risks and
uncertainties  that  could cause the Company's actual results to vary materially
from  those  anticipated.  Risks  and  uncertainties  include  the  inability to
predict  the  outcome  of  appeals  or any negotiation efforts, estimating costs
associated  with  litigation  defense,  estimating  future  royalty  streams for
infringed  products,  the  rate  and timing of customer demand for the Company's
products,  and  other  factors  which  are more fully described in the Company's
reports  on file with the Securities and Exchange Commission.  OnSite undertakes
no  obligation  to  update  publicly  or  revise any forward-looking statements.
