Four Arkansas companies have been cited by OSHA as a result of a crane collapse in March that killed one worker and injured eight others.

OSHA cited Precision Surveillance Corp., Bigge Crane and Rigging Co., Siemens Power Generation Inc. and Entergy Operations Inc. for 26 safety violations after one Precision Surveillance worker was fatally injured when a crane collapsed at the Arkansas Nuclear One Power Plant.

Precision Surveillance Corp., in East Chicago, Ind., is being cited for one serious violation with a penalty of $6,300 for failing to provide an effective communication system to alert the operator or signalman through an emergency stop signal. Bigge Crane and Rigging Co. in San Leandro, Calif., Siemens Power Generation Inc. in Orlando, Fla., and Entergy Operations Inc. in Russellville are being cited for failing to comply with crane-related hazards. Bigge Crane is being cited for nine serious violations with a penalty of $56,700, and Siemens is being cited for nine serious violations with a penalty of $63,000. Entergy is being cited for 7 serious violations with a penalty of $49,000.

"This tragedy could have been prevented had the employer ensured vital safeguards to protect workers from potential hazards and proper planning for a project of this magnitude," said Carlos Reynolds, OSHA's area director in Little Rock.
