WASHINGTON — "Until recently, Lockheed Martin employees manufacturing the C-130J may have been exposed to harmful chemicals, and the Defense Department may have ignored worker concerns, a U.S. senator said Thursday.

Iowa Republican Sen. Chuck Grassley, who leads the Senate Finance Committee, is calling for an investigation by the Defense Department’s inspector general due to the worker claims, which were made by multiple whistleblowers, Grassley said in a statement.

The whistleblowers claimed that using PR-148 in aerosol form created a “large blue cloud” of particles that was equivalent to being exposed to and inhaling “industrial strength airplane glue,” according to Grassley’s letter.

Employees brought health concerns and, later, health issues they believed to be caused by the chemical to Lockheed, but were ignored, he wrote."
