All documents filed by the registrant pursuant to Sections 13(a), 13(c), 14 or 15(d) of the 1934 Act subsequent to the filing of the annual report on Form 10-K referred to in paragraph (a) above and prior to the filing of a post- effective amendment which indicates that all securities offered hereby have been sold or which deregisters all securities then remaining unsold shall be deemed to be incorporated by reference in this Registration Statement and to be a part hereof from the date of filing of such documents, except that the information included in any document in response to paragraphs (i), (k) or (l) of Item 402 of Regulation S-K is not incorporated by reference in this Registration Statement. Any statement contained in a document incorporated or deemed to be incorporated by reference in this Registration Statement shall be deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement contained in this Registration Statement or in any other contemporaneously or subsequently filed document which also is or is deemed to be incorporated by reference in this Registration Statement modifies or supersedes such statement. Any such statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement. Item 4. Description of Securities. Not applicable. Item 5. Interests of Named Experts and Counsel. Not applicable. Item 6. Indemnification of Directors and Officers. 1. Pennsylvania Business Corporation Law. Sections 1741 and 1742 of the Pennsylvania Business Corporation Law (the "BCL") provide that a business corporation shall have the power to indemnify any person who was or is a party, or is threatened to be made a party, to any proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that such person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such proceeding, if such person acted II-1 in good faith and in a manner he reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal proceeding, had no reasonable cause to believe his conduct was unlawful. In the case of an action by or in the right of the corporation, such indemnification is limited to expenses (including attorneys' fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person has been adjudged to be liable to the corporation unless, and only to the extent that, a court determines upon application that, despite the adjudication of liability but in view of all the circumstances, such person is fairly and reasonably entitled to indemnity for the expenses that the court deems proper. BCL Section 1744 provides that, unless ordered by a court, any indemnification referred to above shall be made by the corporation only as authorized in the specific case upon a determination that indemnification is proper in the circumstances because the indemnitee has met the applicable standard of conduct. Such determination shall be made: (1) by the Board of Directors by a majority vote of a quorum consisting of directors who were not parties to the proceeding; or (2) if such a quorum is not obtainable, or if obtainable and a majority vote of a quorum of disinterested directors so directs, by independent legal counsel in a written opinion; or (3) by the shareholders. Notwithstanding the above, BCL Section 1743 provides that to the extent that a director, officer, employee or agent of a business corporation is successful on the merits or otherwise in defense of any proceeding referred to above, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by such person in connection therewith. BCL Section 1745 provides that expenses (including attorneys' fees) incurred by an officer, director, employee or agent of a business corporation in defending any proceeding may be paid by the corporation in advance of the final disposition of the proceeding upon receipt of an undertaking to repay the amount advanced if it is ultimately determined that the indemnitee is not entitled to be indemnified by the corporation. BCL Section 1746 provides that the indemnification and advancement of expenses provided by, or granted pursuant to, the foregoing provisions is not exclusive of any other rights to which a person seeking indemnification may be entitled under any bylaw, agreement, vote of shareholders or directors or otherwise, and that indemnification may be granted under any bylaw, agreement, vote of shareholders or disinterested directors or otherwise for any action taken or any failure to take any action whether or not the corporation would have the power to indemnify the person under any other provision of law and whether or not the indemnified liability arises or arose from any action by or in the right of the corporation, provided, however, that no indemnification may be made in any case where the act or failure to act giving rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness. BCL Section 1747 permits a Pennsylvania business corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or other enterprise, against any liability asserted against such person and incurred by him in any such capacity, or arising out of his status as such, whether or not the corporation would have the power to indemnify the person against such liability under the provisions described above. 2. Indemnification Bylaw. Section 7.01 of the registrant's Bylaws (the "Indemnification Bylaw") was adopted by the shareholders at their Annual Meeting held on April 24, 1987 and became effective on that date. Under the Indemnification Bylaw, except as prohibited by law, every director and officer of the registrant is entitled as of right to be indemnified by the registrant against all expenses and liabilities incurred in connection with any actual or threatened claim or proceeding, whether civil, criminal, administrative, investigative or other, whether II-2 brought by or in the right of the registrant or otherwise, in which the director or officer may be involved in any manner, by reason of his being or having been a director or officer of the registrant or by reason of the fact that he is or was serving at the request of the registrant as a director, officer, employee, fiduciary or other representative of another corporation or other entity. In an action brought by a director or officer against the registrant, the director or officer is only entitled to indemnification for expenses in certain circumstances. Each director and officer is also entitled as of right to have his expenses in defending an action paid in advance by the registrant prior to final disposition of the action, subject to any obligation which may be imposed to reimburse the registrant in certain events. The Indemnification Bylaw establishes a procedure whereby a director or officer may bring an action against the registrant if a written claim for indemnification or advancement of expenses is not paid by the registrant in full within thirty days after the claim has been presented. The director or officer is also entitled to advancement of expenses in this proceeding. The only defense to an action to recover a claim for indemnification is that the indemnitee's conduct was such that under Pennsylvania law the registrant is prohibited from indemnifying the indemnitee. The only defense to an action to recover payment of expenses in advance is failure by the indemnitee to make an undertaking to reimburse the registrant if such an undertaking is required. The Indemnification Bylaw applies to every action, other than actions filed prior to January 27, 1987, except that it does not apply to the extent that Pennsylvania law does not permit its application to any breach or failure of performance of duty by a director or officer occurring prior to January 27, 1987. Any amendment or repeal of the Indemnification Bylaw will operate prospectively only and will not affect any action taken, or failure to act, by a director or officer prior to the adoption of such amendment or repeal. 3. Director and Officer Liability Insurance. The registrant maintains director and officer liability insurance covering its directors and officers with respect to liability which they may incur in connection with their serving as such, which liability could include liability under the Securities Act of 1933. Under the insurance, the registrant is entitled to reimbursement for amounts as to which the directors and officers are indemnified under the Indemnification Bylaw. The insurance may also provide certain additional coverage for the directors and officers against certain liability even though such liability is not subject to indemnification under the Indemnification Bylaw. 4. Indemnification Agreements. At their Annual Meeting held on April 24, 1987, the shareholders also approved a proposed form of Indemnification Agreement to be entered into between the registrant and each of its present and future directors and such other officers, employees and agents of the registrant and its subsidiaries as shall be designated from time to time by the Board of Directors. The form of agreement provides essentially the same rights to indemnification against liabilities and expenses as are provided in the Indemnification Bylaw. In addition, the form of agreement requires the registrant to either maintain the liability insurance coverage currently in effect for the benefit of the contractee or to hold the contractee harmless to the full extent of such coverage. Further, the form of agreement provides that if the full indemnification claimed by the contractee may not be paid by the registrant because prohibited by law and the registrant is jointly liable with the contractee as to the matter for which indemnification was sought (or would be so liable if the registrant were joined in such matter), the contractee has a right to contribution from the registrant for the amount of any expenses and liabilities incurred by the contractee as to such matter based on the relative benefits received by the registrant and the contractee from the transaction from which the liability arose and the relative fault of the registrant (including the registrant's other directors, officers, employees or agents) and the contractee in connection with the events which resulted in such expenses or liability, as well as any other relevant equitable considerations. Under the form of agreement, a contractee is entitled to the rights to indemnification for expenses and liability, advancement of expenses and contribution provided by the agreement notwithstanding any amendment or repeal of the Indemnification Bylaw. In addition, although a change in law restricting indemnification rights would automatically restrict the indemnification rights provided under the Indemnification Bylaw, the form of agreement provides that a change in law restricting indemnification rights will not affect the rights of a contractee under the agreement unless the law so requires. II-3 Item 7. Exemption From Registration Claimed. Not applicable. Item 8. Exhibits. An Exhibit Index, containing a list of all exhibits filed with this Registration Statement, is included on page II-8. Item 9. Undertakings. (a) Rule 415 offering. The undersigned registrant hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) To include any prospectus required by section 10(a)(3) of the Securities Act of 1933 (the "1933 Act"); (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; Provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by the registrant pursuant to section 13 or section 15(d) of the Securities Exchange Act of 1934 (the "1934 Act") that are incorporated by reference in the registration statement; (2) That, for the purpose of determining any liability under the 1933 Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. (b) Filings incorporating subsequent Exchange Act Documents by Reference. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the 1933 Act, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the 1934 Act that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. II-4 (h) Filing of Registration Statement on Form S-8. Insofar as indemnification for liabilities arising under the 1933 Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the provisions described under Item 6 above, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the 1933 Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the 1933 Act and will be governed by the final adjudication of such issue. II-5 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the Township of O'Hara, Pennsylvania, on the 5th day of May, 1998.

     Re:  Registration Statement on Form S-8 for
          the 1998 Management Share Incentive Plan
          ----------------------------------------

Gentlemen:

     We have acted as counsel to Mine Safety Appliances Company, a Pennsylvania
corporation (the "Company"), in connection with the above-captioned Registration
Statement (the "Registration Statement") relating to up to 600,000 shares of
Common Stock, without par value, of the Company (the "Common Stock") which may
be issued under the Company's 1998 Management Share Incentive Plan (the "Plan").
Either authorized but unissued or treasury shares of Common Stock may be issued
under the Plan.  In rendering our opinion below, we have assumed that any
previously issued shares reacquired by the Company and reissued as treasury
shares under the Plan will have been duly authorized, validly issued and fully
paid at the time of their original issuance.

     In connection with this opinion, we have examined, among other things:

          (1)  the Restated Articles of Incorporation and Bylaws of the Company,
     as amended to date;

          (2)  a form of resolutions adopted by the Board of Directors of the
     Company on March 11, 1998 adopting the Plan, authorizing the issuance of up
     to 600,000 shares of Common Stock thereunder and reserving 600,000 shares
     of Common Stock for such purpose;

          (3) the Plan as set forth in Annex A to the Company's definitive Proxy
     Statement dated March 25, 1998 for the Company's 1998 Annual Meeting; and

          (4) a certificate of the judge of elections certifying approval of the
     adoption of the Plan by a majority of the shares of Common Stock voted on
     the proposal at the Company's 1998 Annual Meeting.

     Based upon the foregoing and upon an examination of such other documents,
corporate proceedings, statutes, decisions and questions of law as we considered
necessary in order to enable us to furnish this opinion, and subject to the
assumption set forth above, we are pleased to advise you that in our opinion the
600,000 shares of Common Stock being registered and which may be issued by the
Company pursuant to the Plan have been duly authorized, and upon such issuance
in accordance with the provisions of the Plan, such shares will be validly
issued, fully paid and nonassessable.

     We hereby consent to the filing of this opinion as an Exhibit to the
Registration Statement.

                                         Yours truly,

                                         /s/ Reed Smith Shaw & McClay LLP
