Item 4.  Changes in Registrant's Certifying Accountant

         On June 19, 2002, Iron Mountain  Incorporated (the "Company") dismissed
Arthur Andersen LLP ("Arthur  Andersen") as its independent  public  accountants
and engaged  Deloitte & Touche LLP  ("Deloitte") to serve as its new independent
public  accountants  for the fiscal year ending  December  31,  2002,  effective
immediately.  The decision to dismiss Arthur Andersen and to retain Deloitte was
recommended  by the  Company's  Audit  Committee  and approved by the  Executive
Committee of the Board of Directors, which committee was expressly authorized to
take such action.

         Arthur  Andersen's  reports  on the  Company's  consolidated  financial
statements  for  each of the  years  ended  December  31,  2001 and 2000 did not
contain an adverse  opinion or a disclaimer of opinion,  nor were they qualified
or modified as to uncertainty, audit scope or accounting principles.

         During the years ended  December 31, 2001 and 2000 and through the date
hereof,  there were no disagreements  between the Company and Arthur Andersen on
any  matter  of  accounting   principles  or  practices,   financial   statement
disclosure, or auditing scope or procedure, which disagreements, if not resolved
to Arthur  Andersen's  satisfaction,  would have caused Arthur  Andersen to make
reference to the subject matter in connection  with its reports on the Company's
consolidated  financial  statements for such years; and there were no reportable
events as defined in Item 304(a)(1)(v) of Regulation S-K.

         The  Company  provided  Arthur  Andersen  with a copy of the  foregoing
disclosures.  Attached as Exhibit  16.1 is a copy of Arthur  Andersen's  letter,
dated June 19, 2002, stating its agreement with such statements.

         During the years ended  December 31, 2001 and 2000 and through the date
hereof,  the  Company  did  not  consult  with  Deloitte  with  respect  to  the
application  of  accounting  principles  to  a  specified  transaction,   either
completed  or proposed,  or the type of audit  opinion that might be rendered on
the  Company's  consolidated  financial  statements,  or any  other  matters  or
reportable events as set forth in Items 304(a)(2)(i) and (ii) of Regulation S-K.

Item 7.  Financial Statements, Pro Form Financial Information and Exhibits

(c)      Exhibits.

Exhibit No.    Item

16.1           Letter from Arthur  Andersen LLP to the  Securities  and Exchange
               Commission,  dated  June 19,  2002,  regarding  the change in the
               Company's certifying accountant.

99.1           Press Release, dated June 19, 2002.

       Iron Mountain Engages Deloitte & Touche LLP as Independent Auditors



Boston, MA - June 19, 2002 - Iron Mountain  Incorporated (NYSE: IRM), the global
leader in records and information  management services,  today announced that it
has engaged  Deloitte & Touche LLP as its  independent  auditors  for the fiscal
year ending  December 31, 2002  replacing  Arthur  Andersen LLP in that capacity
effective  immediately.  The  decision  to dismiss  Arthur  Andersen  and engage
Deloitte  &  Touche  was made  after  careful  consideration  by the  Audit  and
Executive  Committees  of the  Iron  Mountain  Board  of  Directors  and  senior
management.  The  decision was not the result of any  disagreement  between Iron
Mountain  and  Arthur  Andersen  on  any  matter  of  accounting  principles  or
practices, financial statement disclosure, or auditing scope or procedure.

"It is with sadness that we end our relationship with Arthur Andersen. They have
been  great  partners   throughout  our  time  as  a  public   company,   always
professional,  always  providing  the highest  level of  service,"  said Richard
Reese,  Iron  Mountain's  Chairman and CEO.  "Unfortunately,  Arthur  Andersen's
current  difficulties  and uncertain future convinced the Board that this change
was in the best  interest of our  shareholders,"  he added.  "We look forward to
working with Deloitte & Touche in their new role as our  independent  auditors,"
said Reese.
