                                                                    SCHEDULE 13D

                          FILED PURSUANT TO RULE 13d-1
                   OF THE GENERAL RULES AND REGULATIONS UNDER
                 THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED


     This  Amendment  No. 3, which  relates to shares of the common  stock,  par
value $0.10 per share (the  "Common  Stock") of Meridian  Medical  Technologies,
Inc.  (the  "Issuer")  and  is  being  filed  by  EM  Industries,  Incorporated,
supplements  and amends the statement on Schedule 13D,  dated November 20, 1996,
and originally  filed with the  Commission on December 2, 1996,  Amendment No. 1
thereto,  dated October 24, 2000,  and filed with the  Commission on October 26,
2000,  and Amendment No. 2 thereto,  dated November 30, 2000, and filed with the
Commission on December 15, 2000.

ITEM 4. PURPOSE OF THE TRANSACTION.

Item 4 of Schedule 13D is amended by the addition of the following:

As described in  Amendment  No. 2 to the Schedule  13D, EM intends to dispose of
the Common Stock and Warrants  that it holds.  Since the filing of Amendment No.
2, EM has sold,  as of the date of this  Amendment  No. 3 to the Schedule 13D, a
total of 18,300 shares of Common Stock in market transactions at then prevailing
market prices,  as set forth below in part (c) of Item 5. EM intends to continue
to dispose  of its Common  Stock in an  orderly  fashion,  as market  conditions
permit and at prices acceptable to it. It will continue to hold its Common Stock
to the extent that these objectives  cannot be achieved.  EM intends to exercise
the Warrants  that it holds  before  November  19,  2001,  thereby  acquiring an
additional  29,038 shares of Common Stock.  No assurance can be given,  however,
that the Warrants will actually be exercised as of such date. EM also intends to
dispose of any shares  acquired  through  the  exercise  of the  Warrants  in an
orderly fashion,  as market conditions permit and at prices acceptable to it, to
the extent permitted by law.

EM's  decision  to dispose of its  interest  in the Issuer was based on the fact
that its  commercial  relationship  with the  Issuer  has  been  assigned  to an
affiliate of EM, that EM's investment in the Issuer was unrelated to its current
strategic plans, and that its investment in the Issuer had appreciated in value,
and was not based on an evaluation of the Issuer's future prospects.

ITEM 5.  INTEREST IN SECURITIES OF THE ISSUER.

Part  (a) of  Item 5 of  Schedule  13D is  deleted  and  amended  to read in its
entirety as follows:

(a) EM directly  owns  182,938  shares of Common  Stock and Warrants to purchase
29,038 shares of Common Stock (together,  the "EM Common Shares"), which amounts
include  the shares of Common  Stock and  Warrants  acquired  in the Merger plus
61,989  shares of Common  Stock  previously  acquired by EM from STI in November
1992 in a  privately  negotiated  transaction.  Based in part  upon  information
provided by the Issuer and calculated in accordance with Rule 13d-3(d)(1)  under
the Exchange Act, the EM Common Shares represent 6.6% of the 3,197,088 shares of
Common Stock outstanding on the date hereof.

(c)  Paragraph  (c) of Item 5 of the  Schedule 13D is amended by the addition of
the following:

During the last sixty days, EM has sold a portion of its shares of Common Stock
in open market transactions as follows:
