5 PM UPDATE: Myrtle Beach Fire Department crews left the scene around 4 p.m. after getting CO levels back to normal.

Crews from Dominion Energy are taking a closer look at what the root of the issue is.

Guests say it was a jarring way to begin the morning.

“I came out and saw these fire guys all in their kits with gas masks. and said I should take whatever I can because of theres a carbon monoxide leak,” Christopher Ezezeihuaku said. He’s a doctor in town to work at Grand Strand Regional Medical Center.

Caroline Newman has a similar recollection.

“They came up into our room with masks on and knocked on the door and said we had to leave quickly,” she remembered. “So we literally left our belongings, threw some clothes on and came out to the door.”

Lt. Jonathan Evans with Myrtle Beach fire says the hotel staff and department reacted quickly.

“Just to stay on the safe side they got everyone outside while we mitigated that and ventilate the building properly,” he said.

Crews were doing that just about all day, a process Evans calls

“This is a very intensive process,” he said. “We have a lot of resources out here trying to mitigate this situation. And we don’t want to happen again.”
