MALLINCKRODT TO CLOSE NELLCOR PURITAN BENNETT FACILITIES IN LENEXA,
KANSAS

ST. LOUIS, Missouri, July 1, 1998 - Mallinckrodt Inc. (NYSE:MKG) will
close two of its three facilities in Lenexa, Kansas.  The facilities
employ about 150 people and were part of the former Nellcor Puritan
Bennett, the respiratory products firm that Mallinckrodt acquired in
August 1997.  The closings are expected to be completed by mid-1999
and will result in annual savings of about $4 million.

     One of the facilities, located at 11150 Thompson Avenue, is a
research and development site that employs about 100 people.  Its
primary purpose is to support the design and development of oximetry
monitoring equipment, which measures the amount of oxygen being
absorbed by a patient's bloodstream.  It also supports the design and
development of spirometry equipment, which is used to measure lung
capacity and efficiency.  The research and development activities
will be relocated to Mallinckrodt Respiratory Group sites in
Pleasanton, California; Carlsbad, California; and St. Charles,
Missouri.  

     The other Lenexa facility, at 10800 Pflumm, houses about 50
Mallinckrodt employees and supports medical gas distribution systems,
which are used within hospitals to move gases from compressors to
outlets.  This business is being divested, and it is anticipated that
the facility will be closed in early 1999.

     Lenexa will continue to serve as the operating center for
Mallinckrodt's medical gas business, which supports a system of 32
gas branches and four nitrous oxide manufacturing facilities across
the country.

     "Our Lenexa employees have made a valuable contribution to
respiratory care over the years," said John Q. Hesemann, president of
Mallinckrodt's Respiratory Group.  "We need to take the actions we
are announcing today to improve the efficiency of Mallinckrodt. 
However, we appreciate the work of our Lenexa employees, and we will
offer many of them the opportunity to relocate.  For those employees
whose jobs are being eliminated, we will provide a number of services
to assist them and their families during this difficult time of
transition."

     Since the acquisition of Nellcor Puritan Bennett, Mallinckrodt
also has been moving support functions in such areas as finance,
accounting and information systems from Lenexa to Chesterfield,
Missouri.  These moves are nearly complete.

     Based in St. Louis, Mo., Mallinckrodt Inc. has three healthcare
product groups - Imaging, Pharmaceuticals and Respiratory.  The
company operates in more than 100 countries and had fiscal 1997 net
sales of $1.9 billion.  The Mallinckrodt web site address is
(www.mallinckrodt.com).
