             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


To the Participants and the Plan Administrative Committee of
the Harsco Retirement Savings and Investment Plan:


In our opinion, the accompanying statements of net assets available for benefits
and the related statement of changes in net assets available for benefits
present fairly, in all material respects, the net assets available for benefits
of the Harsco Retirement Savings and Investment Plan (the "Plan") at December
31, 2004, and the changes in net assets available for benefits for the year
ended December 31, 2004 in conformity with accounting principles generally
accepted in the United States of America. These financial statements are the
responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audit. We conducted our audit
of these statements in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

Our audit was conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets held
for investment purposes is presented for the purpose of additional analysis and
is not a required part of the basic financial statements but is supplementary
information required by the Department of Labor's Rules and Regulations for
Reporting and Disclosure under the Employee Retirement Income Security Act of
1974. This supplemental schedule is the responsibility of the Plan's management.
The supplemental schedule has been subjected to the auditing procedures applied
in the audit of the basic financial statements and, in our opinion, is fairly
stated in all material respects in relation to the basic financial statements
taken as a whole.

                          -----------------------------

1.   Transfer from Harsco Corporation Savings Plan and creation of the Plan:
     -----------------------------------------------------------------------

     Effective January 1, 2004, the account balances of salaried employees in
     the Harsco Corporation Savings Plan totaling $110.9 million were spun off
     to create the Harsco Retirement Savings and Investment Plan (the "Plan").
     The spin off was made in connection with the Company restructuring salaried
     employees' defined benefit pension plans from principally defined benefit
     to principally defined contribution. Hourly and salaried Air-X-Changers
     employees remain in the Harsco Corporation Savings Plan.

2.   General Description of Plan:
     ----------------------------

     The following description of the Plan provides only general information.
     Participants should refer to the Summary Plan Description for a more
     complete description of the Plan's provisions.

     The Plan is a defined contribution plan designed to comply with the
     requirements of the Employee Retirement Income Security Act of 1974
     ("ERISA") and with the requirements for qualification under Sections 401(a)
     and 401(k) of the Internal Revenue Code (the "Code").

     All U.S. salaried non-union employees (including officers) who are employed
     by Harsco Corporation (the "Company") or any subsidiary of either the
     Company or a subsidiary which adopts this Plan with the approval of the
     Company shall be covered by, or remain covered by this Plan, are deemed
     "Eligible Employees." Also eligible are employees covered by a collective
     bargaining agreement where the agreement provides for the employees'
     eligibility to participate in the Plan. New employees deemed Eligible
     Employees under this Plan are eligible to participate in the Plan as of the
     first payroll of January, April, July or October after the date of hire.

     To participate in the Plan, an Eligible Employee must elect to contribute
     to the Plan through payroll deductions each pay period. Contributions are
     in whole percentages from 1% to 75% of compensation received for services
     as an employee of the Company or any subsidiary of the Company. The
     participant shall designate what percentage of such contributions will be
     "Pre-Tax Contributions" and what percentage will be "After-Tax
     Contributions." A participant who makes Matched Pre-Tax and/or Matched
     After-Tax Contributions in an aggregate amount of 6% of his or her
     compensation may also elect to contribute from 1% to 69% of his or her
     compensation as an Unmatched Pre-Tax Contribution and from 1% to 16% of his
     or her compensation as an Unmatched After-Tax Contribution, subject to IRS
     and Plan limitations. In no event during the year may (a) Matched Pre-Tax
     and Matched After-Tax Contributions exceed 6% of compensation, (b)
     Unmatched Pre-Tax and Unmatched After-Tax Contribution exceed 69% of
     compensation or (c) Pre-Tax Contributions exceed the amount specified by
     the Internal Revenue Service (IRS) code which was $13,000 for the year
     ended December 31, 2004 for

                                       -6-

                    ----------------------------------------

2.   General Description of Plan: (continued)
     ----------------------------------------

     participants under 50 years of age. For participants who turned 50 on or
     before the end of the calendar year, the pretax limit was $16,000 in 2004
     as a result of an additional $3,000 "catch-up contributions" allowed by law
     in 2004. Pre-Tax Contributions shall constitute a reduction in the
     participant's taxable income for purposes of Section 401(k) of the Code.
     After-Tax Contributions will be considered to be the participant's
     contributions to the Plan and shall not constitute a reduction in the
     participant's taxable income for the purposes of Section 401(k) of the
     Code.

     Pursuant to the Plan, the Company will make contributions in cash to the
     trustee for the account of each participant in an amount equal to 100% of
     the first 3% of such participant's compensation designated as Matched
     Pre-Tax Contributions and/or Matched After-Tax Contributions, and 50% of
     the sum of the next 2% of each eligible Participant's Matched Pre-Tax
     Contributions and/or Matched After-Tax contributions for the period. These
     contributions are referred to as "Company Matching Contributions".

     As of December 31 of each plan year, the employer may make a Company
     discretionary contribution to the Plan in an amount determined by the
     Company's board of directors. Employer discretionary contributions are
     allocated to the accounts of eligible participants in the proportion that
     each eligible participant's compensation bears to the aggregate
     compensation of all eligible participants who are entitled to an allocation
     of the Company discretionary contribution for that Plan year.

     Participants are immediately vested in their contributions plus actual
     earnings thereon and current Company Matching Contributions to the Plan.
     Vesting in the Company's Harsco Savings Matching Accounts and discretionary
     contributions are based on years of vesting service. A participant is 100%
     vested in the Company's Matching Accounts transferred from the Harsco
     Savings Plan after three years of credited service. A participant is 100%
     vested in the Company's discretionary contributions after five years of
     credited service.

     The Company pays administrative fees related to maintaining the Plan as a
     whole. Fees for investment management are subtracted from fund performance
     reported by each fund. Loan setup fees, quarterly loan fees and withdrawal
     fees are paid by the participant. Transfers in and out of the Harsco
     Corporation Common Stock Fund are assessed a $0.03 commission per share
     transferred.

     Participants may borrow from their fund accounts a minimum of $500 to a
     maximum of 50% of their vested account balance, not to exceed $50,000. Loan
     transactions are treated as a transfer to (from) the respective investment
     fund(s) from (to) the Participant Loans fund. The participant may choose
     the loan repayment period, not to exceed five years. However, the term may
     be for any period not to exceed 15 years if the purpose of the loan is to
     acquire the participant's principal residence. The loans are collateralized
     only by the portion of the participant's account from which the loan is
     made

                                       -7-

     and bear interest at a rate commensurate with local prevailing rates as
     determined periodically by the Plan administrator. Interest rates on
     outstanding loans, based on the trustee's prime rate plus one percent,
     ranged from 5.00% to 10.5% at December 31, 2004. Principal and interest is
     paid ratably through payroll deductions.

     On termination of service, a participant or beneficiary may elect one of
     three options. The participant or beneficiary may elect to receive either a
     lump-sum amount equal to the value of the participant's vested interest in
     his or her account; a portion paid in a lump-sum, and the remainder paid
     later; or annual installments over not more than fifteen years.

     While the Company has not expressed any intent to discontinue the Plan, it
     reserves the right to terminate the Plan at any time or discontinue
     contributions thereunder. In the event such discontinuance resulted in the
     termination of the Plan, the accounts of each affected employee who has not
     yet incurred a break in service shall be fully vested. Complete
     distributions or withdrawals would be distributed to Plan participants and
     beneficiaries in proportion to their respective account balances.

3.   Summary of Significant Accounting Policies:
     -------------------------------------------

     Basis of Accounting:
     --------------------

     The financial statements of the Plan are prepared under the accrual basis
     of accounting.

     Investment Valuation:
     ---------------------

     The Harsco Corporation Common Stock Fund is stated at market value, which
     represents the closing price of the stock on the Composite Reporting Tape
     of the stock exchanges on the last day of trading of the calendar year.
     Shares in the American Funds EuroPacific Growth Fund, American Funds Growth
     Fund of America, Ariel Appreciation Fund, Dodge & Cox Stock Fund, Morgan
     Stanley Institutional Fund, Inc. U.S. Real Estate Fund, Neuberger Berman
     Genesis Fund, PIMCO Total Return Fund, Putnam Bond Index Fund, Putnam Fund
     for Growth and Income, Putnam Income Fund, Putnam Money Market Fund, Putnam
     New Opportunities Fund, Putnam Voyager Fund, Vanguard Institutional Index
     Fund, Putnam Retirement Ready Funds and T. Rowe Price Retirement Funds are
     valued at net asset value, which represents fair value. Cash, which
     represents funds held until purchases of common stock are completed, is
     stated at fair value. Participant loans are valued at cost which
     approximates fair value.

     Payment of Benefits:
     --------------------

     Benefit payments to participants are recorded when paid.

                                       -8-

                    ----------------------------------------

3.   Summary of Significant Accounting Policies: (continued)
     -------------------------------------------------------

     Use of Estimates:
     -----------------

     The preparation of financial statements in conformity with generally
     accepted accounting principles requires management to make estimates and
     assumptions that affect the reported amounts of assets and liabilities and
     disclosures of contingent assets and liabilities at the date of the
     financial statements and the reported amounts of additions and deductions
     during the reporting period. Actual results could differ from those
     estimates.

     Other:
     ------

     The Plan presents in the Statement of Changes in Net Assets Available for
     Benefits the net appreciation (depreciation) in the market value of its
     investments which consists of the realized gains or losses and the
     unrealized appreciation (depreciation) on those investments.

     The purchase and sale of investments are recorded on a trade-date basis.
     Dividend income is recorded on the ex-dividend date. Income from other
     investments is recorded as earned on an accrual basis. Both participant
     contributions and Company matching contributions are accrued in the period
     of the related payroll deductions. Forfeitures, a result of participant
     withdrawals prior to their full vesting in the Plan, are used to reduce the
     amount of future Company matching contributions. In 2004, forfeited amounts
     of $91,298 were used to offset Company matching contributions and $14,348
     remained in a money market fund at December 31, 2004 to be used to offset
     future Company matching contributions.

     The Plan provides for various investment options as described above.
     Investment securities are exposed to various risks, such as interest rate,
     market, and credit. Due to the level of risk associated with certain
     investment securities and the level of uncertainty related to changes in
     the value of investment securities, it is at least reasonably possible that
     changes in risks in the near term could materially affect participants'
     account balances and the amounts reported in the statement of net assets
     available for plan benefits and the statement of changes in net assets
     available for plan benefits.

     There were 1,847 participants at December 31, 2004 who participated in one
     or more of the 33 investment funds. At December 31, 2004 the number of

5.   Related-Party Transactions:
     ---------------------------

     Certain Plan investments are shares of mutual funds managed by Putnam
     Investments. Putnam Investments is the trustee as defined by the Plan, and
     therefore, transactions in these funds qualify as party-in-interest
     transactions. Transactions in the Harsco Corporation Common Stock Fund also
     qualify as party-in-interest transactions.

                    ----------------------------------------

6.   Plan Amendment:
     ---------------

     The Company amended the Plan effective January 1, 2004, to include rollover
     contributions when determining whether a Participant's account exceeds
     $5,000. This threshold is used to determine if a Participant's balance will
     be immediately paid-out to the participant upon the participant leaving
     employment with the Company or if it will remain in the Plan until the
     Participant chooses to withdraw it.

7.   Federal Income Taxes:
     ---------------------

     The Company received a determination letter from the Internal Revenue
     Service on May 19, 2005 that the Plan is a qualified plan under Sections
     401(a) and 401(k) of the Internal Revenue Code and is therefore exempt from
     Federal income taxes under the provisions of Section 501(a). The Plan has
     been amended since the IRS made its determination. However, the Plan
     administrator and the Plan's tax counsel believe that the Plan is designed
     and is currently being operated in compliance with the applicable
     provisions of the Internal Revenue Code.

8.   Subsequent Event - 2% Discretionary contribution:
     -------------------------------------------------

     In February 2005, the Company made a discretionary contribution totaling
     $1.8 million equal to 2% of the compensation paid to Plan participants in
     2004. The discretionary contribution will be recorded as a 2005
     contribution.
