Evacuation Due to Strong Ammonia Odor in Building

Summary: A strong, unusual odor—identified as ammonia—was reported in a building, primarily affecting the third and fourth floors. The security officer initiated an evacuation at 1811 hours due to the intensity of the odor, which was causing discomfort. Emergency services responded, investigated the source (notably room 305), and monitored for hazardous readings. Some residents, including those on oxygen and those unable to evacuate, required special attention. After investigation, the first and second floors were cleared for reentry, while the third and fourth floors remained restricted pending further assessment.
