Airgas distribution center shut after blast, two injured

An Airgas Inc distribution center in Putnam Country, West Virginia, has been closed after two people were injured in an explosion and fire at the facility, the company said on Monday. The center handles industrial gases including nitrogen, acetylene and oxygen that do not pose an immediate threat to public safety, though a section of adjoining highway has been closed, said Jason Owens, deputy director of public safety at the Putnam County Office of Emergency Management.
