ITEM 5.  OTHER EVENTS.

     On November 14, 1997, the Board of Directors of Safety-Kleen Corp. (the
"Company") determined that in light of the public announcement on November 4,
1997 by Laidlaw Environmental Services, Inc. ("LES") that it intends to file
documents with the Securities and Exchange Commission with respect to an offer
to acquire the common stock of the Company (the "Offer"), it was advisable for
the administration of the Rights Agreement dated November 9, 1988, as amended
(the "Rights Agreement"), between the Company and the First National Bank of
Chicago, as Rights Agent, that the occurrence of the Distribution Date (as
defined in the Rights Agreement) as it applies to the Offer be deferred to a
later date. Pursuant to a resolution adopted at the November 14, 1997 meeting,
the Company's Board of Directors resolved that, for purposes of the Offer, the
Distribution Date shall not occur until the earlier of (i) the "Close of
Business" (as defined in the Rights Agreement) on the tenth day after the Shares
Acquisition Date (as defined in the Rights Agreement) and (ii) the Close of
Business on such date on or after November 19, 1997 as may be determined by the
Board of Directors of the Company before any Person becomes an Acquiring Person
(as defined in the Rights Agreement).

     On November 18, 1997, the Company issued a press release announcing that
it filed a lawsuit in Federal District Court for the Northern District of
Illinois against LES.  The full text of the press release is filed herewith as
Exhibit 99.1, which press release is incorporated herein by reference.
