A massive fire at a refrigerated warehouse in Boyle Heights, Los Angeles, has been burning for nearly a week, blanketing southeast L.A.
County and the San Gabriel Valley in toxic smoke.

Impact & Risks

The prolonged exposure to toxic smoke poses significant health risks, particularly for vulnerable groups such as children, pregnant women, and individuals with pre-existing respiratory conditions. Experts warn that the microscopic particles in the smoke can penetrate deep into the lungs, potentially causing long-term damage, heart attacks, strokes, and even cancer. Community advocates have criticized the lack of mandatory evacuations, citing the presence of highly toxic gases like hydrogen cyanide and isocyanates in the smoke.
