A fire in LA has been burning for days. What’s taking so long to put it out?

Los Angeles firefighters have been battling a fire at a large warehouse in Boyle Heights for six days, a duration significantly longer than typical warehouse fires which are often extinguished within a day. The blaze is occurring at a roughly 500,000-square-foot facility that stores frozen food and is insulated like a freezer, contributing to the prolonged effort. Smoke has been observed billowing from the warehouse, which is also covered in solar panels, impacting the air quality in the surrounding area. The extended duration of the fire is attributed to the nature of the materials stored and the building's construction, designed to maintain extremely low temperatures.
