17 Affected By 'Unknown Substance,' Hazmat Team Called To Sober House: LAFD

LOS ANGELES — Seventeen people were affected Monday by an “unknown substance” that brought hazardous material specialists to a sober living and recovery home in Tarzana, authorities said.

Emergency personnel responded around 11:30 a.m. to a house in the 18000 block of West Cassandra Street, according to the Los Angeles Fire Department.

Six people — three men and three women, ages 23 to 59 — were taken in fair condition to receive medical attention in connection with the incident, authorities said, with two transported before the situation was declared a hazmat incident.

Eleven others who had been exposed were decontaminated and released at the scene, according to the department, which reported that the substance had not been identified as of mid-afternoon, but that all air readings were normal.
