March 20 (Reuters) - FedEx Corp will screen every package at the Texas facility where a parcel exploded on Tuesday, according to a FedEx manager, describing extraordinary steps the company is taking in response to a series of bombings in the state capital.

The package delivery company will also X-ray entire truckloads of parcels at its sorting facility outside Austin, and then divert them elsewhere for sorting and delivery, said the FedEx employee who was not authorized to speak on the record. The source does not work at the sorting facility but was briefed on the situation.

FedEx spokesman Jim McCluskey said he had no immediate comment.

The blast at FedEx on Tuesday was one of six explosions in Texas in the past 18 days. The attacks have killed two people, injured others and left hundreds of federal and local investigators scrambling to find the perpetrator and a motive.

Package screening is not routine at the nation's big delivery companies such as FedEx, United Parcel Service Inc or the U.S. Postal Service. The industry delivers a total of around 40 million parcels in the United States each day, industry experts said. Checking every package on a regular basis would virtually paralyze their operations.

FedEx will carry out the special screenings at the sorting facility in Schertz, Texas where the package exploded, injuring one worker, and at a second location in Austin, where another explosive device was found, the employee said. The second package was turned over to police.

"FedEx in conjunction with the authorities are field X-raying all the packages one at a time," the employee said. "From then on, we will be doing bulk X-rays of entire trailers."

Packages will likely be delayed by a day or two at the facility, and FedEx was re-routing all other packages to its hub in Houston to avoid further delays, he said.

FedEx has provided law enforcement with "extensive evidence from our advanced technology security systems designed to protect the safety of our teammates, our customers and the communities we serve," Chief Executive Officer Fred Smith told analysts on Tuesday after the company reported quarterly financial results.

FedEx will provide authorities with the location where the package was picked up by the driver and the time, the employee said, providing authorities with a wealth of data.

Satish Jindel, a founder of the delivery company that became FedEx Ground and now serves as president of ShipMatrix, which tracks on-time shipments, said it was highly unlikely that the industry would move toward routine screening. Package bombs are rare, he said, making it unrealistic to check every package, every day, considering the enormous cost.
