Item 4.01.     Change in Registrant's Certifying Accountant.

     On December 2, 2004, upon  recommendation  and authorization from the Audit
Committee  of the  Board  of  Directors  of MFRI,  Inc.  (the  "Company"  or the
"Registrant"),  the  Company  decided  to  engage  Grant  Thornton  LLP  ("Grant
Thornton")  as the  Company's  independent  registered  public  accounting  firm
commencing with the audit for its fiscal year ending January 31, 2005.  Deloitte
& Touche  LLP will  continue  as the  Company's  independent  registered  public
accounting firm through the filing of the Company's quarterly report on Form 10Q
for the quarter ended October 31, 2004.

     During the two fiscal  years  ended  January 31, 2004 and during the fiscal
year ended  January 31, 2005  through the date of this Form 8-K, the Company did
not  consult  Grant  Thornton  with  respect to the  application  of  accounting
principles as to a specified  transaction,  either completed or proposed, or the
type of  audit  opinion  that  might  be  rendered  on the  Company's  financial
statements,  or any other  matters  or  reportable  events as set forth in Items
304(a)(3)(i) and (ii) of Regulation S-K.

Item 5.02.     Departure of Director or Principal Officers;  Election of
Directors; Appointment of Principal Officers.

     On December 2, 2004 the Company's Board of Directors elected Executive Vice
President  Bradley E.  Mautner,  age 48, to the position of President and to the
newly created  position of Chief  Operating  Officer.  In his new position,  Mr.
Mautner  will  be  responsible  for the  Company's  day to day  operations.  The
Company's Chairman, David Unger, retains his responsibilities as Chief Executive
Officer and will devote his attention to special  projects,  corporate  strategy
and longer term considerations.

     Mr.  Mautner  has been  employed by the  Company  and its  predecessors  in
various  executive  and  administrative  capacities  since  1978,  has served as
Executive Vice President  since December 2002, was Vice President of the Company
from December 1996 through  December 2002 and has been a director of the Company
since 1995.  From 1994 to the  consummation  of the merger with  Midwesco,  Inc.
("Old  Midwesco") in December 1996, he served as President of Old Midwesco,  and
since  December  30,  1996 he has  served  as  Chief  Executive  Officer  of New
Midwesco, Inc. ("New Midwesco"),  the company which succeeded to the non-Thermal
Care business of Old Midwesco.  In addition,  since  February 1996, he served as
the Chief Executive  Officer of Midwesco  Services,  Inc. which was 50% owned by
New  Midwesco  until  May 19,  2000,  at which  time it  became  a wholly  owned
subsidiary of New Midwesco.  On November 17, 2000,  Midwesco Services,  Inc. was
merged into New  Midwesco.  From February 1988 to January 1996, he served as the
President of Mid Res Inc. (predecessor to Midwesco Services, Inc.).

     Mr. Mautner is the son of Henry M. Mautner, a director and Vice Chairman of
the Board of Directors of the Company.
