The South Coast Air Quality Management District issued a smoke advisory due to the massive structure fire in Boyle Heights.

The AQMD issued the following advisory Wednesday afternoon:

As LAFD continues the firefight, be aware that significant fire with smoke is impacting the area of Boyle Heights. If sensitive to health issues, go indoors. Close all doors/windows and limit outside activities. Limit exposure to outdoor air. For emergencies call 911. Monitor the situation for additional protective actions.

The fire at the cold storage facility in Boyle Heights could involve potentially hazardous materials, possibly impacting your health and air quality.

It's not exactly clear what specific chemicals are involved, but authorities are telling area residents to shelter-in-place, bring all pets and people indoors, close all doors and windows, turn off the air condition system and air purifiers if you have them.

If you're driving past the fire, it's recommended that you switch to recycled air in your vehicle.

The fire at the cold storage facility in Boyle Heights could involve potentially hazardous materials, possibly impacting your health and air quality.

When exposed to extreme heat, these materials can break down into hazardous fluoride gasses and vapors.

Though it's not certain exactly what chemicals are burning, these types of fumes can be dangerous to everyone - for those who are healthy and especially those who are vulnerable, like people with asthma, coronary disease. These individuals have reduced lung function, and particulate matter can go deep into their lungs, and it can be hard to get rid of.

So what can this do? It can cause inflammation, irritation and coughing. In worst case scenarios, it can land you in the emergency room.

While lanes are still open on nearby freeways, the smoke is causing delays on the 5 and 710 freeways.

The impact is on the eastbound 5 lanes and the southbound 710 lanes.
