Do you smell smoke from the Boyle Heights fire? Here’s what you should do about it

As the Boyle Heights warehouse fire burns into its sixth day, SoCal residents are increasingly concerned about the air quality and potential health risks that come with breathing in the smoke. So, what alerts have been issued so far and how can residents be prepared?

Both Gov. Gavin Newsom and Mayor Karen Bass declared a state of emergency on Saturday, a designation that helps California coordinate with local agencies to make sure there are enough resources for the firefight and residents who have been affected after a fire started at a cold storage industrial facility. Los Angeles County Supervisor Hilda Solis said at a press conference Monday that  the county is "delivering supplies, air filters, and air purifiers" to local households.

Los Angeles County public health officials and the South Coast Air Quality Management District (AQMD) also issued a particle pollution advisory that remained in effect until today. Affected areas included: Central Los Angeles County, the San Gabriel Valley, East San Fernando Valley and Northwest San Bernardino Valley.

Although recent air quality readings appear as “moderate” to “good” on South Coast AQMD’s website, the fire is still burning and might be for a few more days.

So what can SoCal residents do to protect themselves?

If the air quality index reads “good” or “poses little to no risk” in some areas, hazardous ash can still be present. If you see ash on your car, or windowsills, you might want to stay inside if possible. In “moderate” or yellow zones, unusually sensitive people are also recommended to avoid longer periods outside.

In the next few days, some might notice windblown ash floating in the air or coating outdoor surfaces. These particles are otherwise known as “fine particulate matter,” which consists of soot, burned plastic and perhaps even traces of the spoiling frozen food from inside the warehouse.

Why that matters

Too much exposure from these materials may cause temporary irritation to the eyes, nose, throat and lungs. If you suffer from health issues that are exacerbated by poor air quality, like respiratory illnesses, you may be affected by these conditions even more.

Four expert tips to protect yourself and your family:

• If you smell smoke or see ash, try to remain indoors with the windows closed. If you can’t, consider stepping outside with an N-95 mask, and refrain from engaging in any rigorous physical activity. 
• In your homes, also avoid using whole house fans (air conditioning is okay), as they can bring in the polluted air from outdoors. 
• If you have an air purifier, this is the time to use it. 
• Avoid using fireplaces, candles and vacuums, as they can introduce toxins into the clean, indoor environment.
