Odor Investigation and Partial Evacuation at Monarch Mills Way

Summary: Emergency services responded to reports of a strong, unidentified odor—possibly ammonia—at 7570 Monarch Mills Way in Howard County, Maryland. The odor was primarily detected on the third and fourth floors of a four-story multi-family residential building. The situation prompted partial evacuation, especially as some residents experienced dizziness and others were unable to evacuate due to mobility or medical needs (e.g., oxygen use). Fire and rescue teams investigated the source of the odor, found no hazardous readings, and coordinated phased re-entry for residents on the first and second floors while continuing to monitor the upper floors.
