*On June 4,1996, the Mine Safety Appliances Company Stock Compensation
Trust (the "Trust"), of which PNC Bank, National Association, acts as
Trustee, purchased 600,000 shares of common stock, no par value, of
Mine Safety Appliances Company (the "Company"). The purchase price for
such common stock was paid for by a loan from the Company to the
Trustee as evidenced by a promissory note. The Trust was established
and the Company's common stock so purchased to provide assurance of the
availability of the shares of the Company's common stock necessary to
satisfy certain obligations of the Company and its subsidiaries under
certain designated non-qualified employee plans, in accordance with a
Trust Agreement effective as of June 1, 1996. Pursuant to this
amendment to Schedule 13G, PNC Bank, National Association, as Trustee
of the Trust, reports that it has no voting power, but may have shared
dispositive power, with respect to the 567,630 shares held in the Trust
as of December 31, 1999. The filing of this amendment does not
constitute, and should not be construed as, an admission that either
PNC Bank, National Association, as Trustee of the Trust, or the Trust
beneficially owns such securities. In connection therewith, the Trustee
and the Trust disclaim beneficial ownership of such securities.
