* 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 these 600,000 shares held in the Trust. 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.
