A busy week already for the Cedar Rapids Fire Department. Firefighters responded to at least four first alarm fires in less than 24 hours on Monday, including one around noon at the Westrock industrial site. The building had to be evacuated while crews put out the fire in a compacting machine. Crews were also called to a garage fire just before 2 a.m. and another fire at an apartment complex downtown around 5 a.m. After firefighters were called out to another house fire on the southwest side Monday evening, they called Iowa's News Now to remind viewers like you to be careful. "Today we've had 38 calls so far in the first 12 hours. Normally we have about 35 to 40 in a 24 hour period," Cedar Rapids Fire Department Battalion Chief Jason Andrews said.
