Synopsis: ABOUT 10:50 A.M. ON 12/11/98, WHILE ATTEMPTING TO INSTALL A UTILITY POLE SUPPORT ANCHOR IN A CITY SIDEWALK IN ST. CLOUD, MN, A COMMUNICATIONS NETWORK INSTALLATION CREW FROM CABLE CONSTRUCTORS, INC., (CCI) STRUCK AND RUPTURED AN UNDERGROUND, 1-INCH-DIAMETER, HIGH-PRESSURE PLASTIC GAS SERVICE PIPELINE, THEREBY PRECIPITATING A NATURAL GAS LEAK. ABOUT 39 MINUTES LATER, WHILE UTILITY WORKERS AND EMERGENCY RESPONSE PERSONNEL WERE TAKING PRELIMINARY PRECAUTIONS AND ASSESSING THE SITUATION, AN EXPLOSION OCCURRED. AS A RESULT OF THE EXPLOSION, 4 PERSONS WERE FATALLY INJURED; 1 PERSON WAS SERIOUSLY INJURED; AND 10 PERSONS, INCLUDING 2 FIREFIGHTERS AND 1 POLICE OFFICER, RECEIVED MINOR INJURIES. SIX BUILDINGS WERE DESTROYED. DAMAGE ASSESSMENTS ESTIMATED PROPERTY LOSSES AT $399,000.

Probable Cause: The National Transportation Safety Board determined that the probable cause of this accident was the lack of adequate procedures by CCI to prevent damage to nearby utilities when its anchor installation crews encountered unusual conditions such as striking an underground obstacle. Contributing to the severity of the accident was the delay by CCI in notifying the proper authorities.
