Before this alarm was struck out, it was elevated to a 3-11 and there was an EMS Plan I.

About 3 p.m. the alarm was raised to a 3-11 alarm, and added an Emergency Medical Services Plan 1 mostly as a precaution, said fire spokesman Quention Curtis.

At least one firefighter was checked over because of the extreme heat, but there were no immediate reports of other injuries, he said.

The fire has affected at least two buildings, including one 3-story courtyard apartment building.
