RADNOR, Pa. -- December 03, 2012

Airgas, Inc. (NYSE: ARG) Executive Chairman Peter McCausland will be honored
with a lifetime achievement award by Chemical Marketing & Economics (CM&E), a
topical group of the American Chemical Society's New York section (ACS NY).
McCausland will accept the award during the group’s Awards for Leadership at
the Yale Club in New York City on Thursday, December 6.

McCausland is being recognized for his many years of leadership at Airgas, one
of the nation’s leading suppliers of industrial, medical and specialty gases.
McCausland founded Airgas in 1982 with the purchase of Connecticut Oxygen, an
industrial gas distributor with approximately $3 million in sales. Through
strategic growth initiatives and more than 400 acquisitions in 30 years,
McCausland has led Airgas to become one of the premier industrial gas
companies in the U.S., with sales of more than $4.7 billion in its most recent
fiscal year. Since its initial public offering in 1986, Airgas has delivered a
total return to shareholders that is among the highest in the S&P 500 index.

“Few people can found a company, help propel it for three decades and turn it
into a consistent top performer in its class,” said George Rodriguez, chairman
of CM&E, board member of ACS NY Section and director at Argeni. “Mr.
McCausland is a pioneer who has remained undaunted when faced with challenging
market shifts. His passion for creating an environment focused on customers,
strengthening operational efficiencies and helping society through his
foundation constitutes an exemplary pillar for the chemical industry.”

“The CM&E group of the American Chemical Society provides a strong foundation
for professional networking and science education, which is fundamental for
future generations,” McCausland said. “I am honored to receive this lifetime
achievement award and would like to express my profound gratitude to the CM&E
group for this recognition and to the more than 15,000 Airgas associates who
work tirelessly to bring value to our customers every day.”

The Awards for Leadership have been established by CM&E to honor individuals
for extraordinary contributions in the chemical industry. The CM&E Board
identified a pool of nominees with exceptional credentials to match the high
selectivity hallmark of ACS NY Section. The CM&E awards are endorsed by the
American Chemical Society, the world’s largest scientific society with 160,000
members. Funds raised through the Awards for Leadership will help bolster ACS
scholarships, National Chemistry Week (K-12) and other science education
programs. For more information about CM&E awards, events and sponsorships,
