Beatrice Karlsson, spokeswoman for the Ice Hotel in Kiruna, said officials with the National Housing Board told managers they would have to install fire alarms at the hotel, which is built every year using chunks of frozen water from the Torne River, The Local.se reported Friday.
"We were a little surprised when we found out," Karlsson said. "But we do understand. Safety is a primary concern for us. There are indeed things that can catch fire, like the reindeer skins, the mattresses, and the pillows."
Karlsson said hotel administrators expect a few surprises with each new season.
"Every hotel is brand new anyway, there is always something new to think about. And this year is no different, we actually have a few surprises in store," the spokeswoman said.
The hotel made its debut in 1990 and has been rebuilt each year since.
