Airgas is expanding in the Philadelphia area after Falls Township Supervisors approved the development of a nine-acre site at Keystone Industrial Port Complex.

After a presentation and thorough review, the governing body voted unanimously to grant approval of a minor subdivision, as well as preliminary and final land development to Airgas.

Airgas, an Air Liquide company, plans to construct an air separation plant on a portion of the former US Steel property and expects to create 25 new jobs through the development at Fairless Hills.

Airgas is awaiting a permit from the Department of Environmental Protection, which officials said should be approved by mid-November.

Radnor-based Airgas is a supplier of industrial, medical and specialty gases, welding technologies, and safety products which employs more than 1,200 people in the greater Philadelphia area.
