Toxic Exposure; INC#1556; 07:49PM; 7320 W Hawthorn Av; https://bit.ly/3Xoo29t; Hollywood; Firefighters are on scene of a large, 5 story modern center hall apartment building (4 residential over parking). Multiple carbon monoxide alarms activated on the 1st and 2nd occupied floors. Firefighters made entry and the 5-sensor gas monitor indicated the presence of hydrogen cyanide as well as carbon monoxide, predominately in one corner of the building on the 1st occupied floor. Occupants of the three units in the area of highest concentration were evacuated and the units are being ventilated. Additionally, firefighters are evacuating the units above those, on the 2nd occupied floor. All others are being sheltered in place while firefighters continue to check levels in the surrounding units (it is dropping off significantly as they move further down the hall). There were construction workers doing repairs (including welding) on the ducting for the heating/air conditioning in the most affected unit. LAFD Hazardous Materials Squad is responding and consulting with the Incident Commander while enroute. At this time, there are no occupants with medical complaints.; FS 41; Batt 5; West Bureau; Council District 4; BC5 E21 E221 E41 RA21 RA82 SQ21; CH7; 13; Margaret Stewart
