On Monday, Louisiana State University (LSU) became the fourth college in as many days to be forced to evacuate its campus due to a bomb threat.

University spokeswoman Christine Calongne told CNN that the call came in around 10:30 a.m. with an unspecified threat of a bomb on school grounds.

Interim president William Jenkins' made the decision to evacuate the campus. 

"The decision had to be made to clearly protect those for whom we are responsible – our faculty, our staff, our students and those visiting our campus," said Jenkins, who is also interim chancellor at Louisiana's flagship university. "We cannot place anyone at risk with a threat such as this."

The article went on to say that by 8 p.m., all residential buildings had been deemed safe and students were allowed back in. There were no specific buildings mentioned in the call and Calongne said that it was too early to speculate on motives.

Last Friday, the University of Texas at Austin, North Dakota State University and Hiram College, a private liberal arts college in Ohio, all evacuated their campuses following threats from unknown callers. According to Time, the calls were seemingly unrelated.

FBI spokesman Jason Pack, told CNN that the agency was working with "affected jurisdictions" to see if there was a link to any of the campus threats.

Businesses and organizations need to find the right balance of keeping the safety of their stakeholders a top priority while still ensuring that their daily operations run smoothly. Instilling tabletop exercises helps organizations prepare for when actual evacuations – such as the one at LSU – need to take place.

Working with a business continuity consultant can better prepare any enterprise for disasters by helping them create contingency plans that will keep individuals safe and ensure their operations continue moving efficiently.
