Airgas Announces Pricing Actions Effective June 1, 2010

RADNOR, Pa.--(Business Wire)--
Airgas, Inc. (NYSE:ARG) today announced that beginning June 1, 2010, or as
contracts permit, its operating units will increase prices on bulk and packaged
gases, and other products and services. Prices will increase, on average, as
follows:

* 6 - 9% for all bulk and packaged industrial, medical, and specialty gases
* 5 - 10% for cylinder and bulk tank rental rates
* 3 - 6% for welding hardgoods and safety products

Rising costs for raw material, power, fuel, and labor and benefits have led to
increases in product costs from suppliers as well as operating costs at Airgas
plants and distribution facilities. The company also has seen higher prices for
welding hardgoods and safety products, cylinders, bulk tanks, gas handling
plants and equipment, in addition to rising costs of regulatory compliance, all
of which factored into the pricing actions.

"Nearly two years have passed since our last across-the-board price increase,
and the pace of cost increases is now accelerating as the economy recovers,"
said Airgas Chairman and Chief Executive Officer Peter McCausland. "Airgas
associates are working hard every day to meet our customers` needs. We continue
to leverage our industry-leading infrastructure and comprehensive product and
service offering so we can safely and efficiently meet the demands of our
customers."
