When they\u2019re from a warehouse fire burning refrigerant chemicals and solar panels, the toxic components and effects are unknown \u2014 and troubling.<\/p>\n<p>\u201cWhat makes this fire unique is the composition of these particles could be very different,\u201d Yifang Zhu, a professor in the UCLA Department of Environmental Health Sciences, said Monday, June 22. \u201cThere is a lot of construction materials, solar panels and electronics burning. The resulting smoke can be more toxic.\u201d<\/p>\n<p>For Los Angeles, a city that knows a thing or two about fake disasters made into movies about man-eating sharks, towering buildings ablaze, devastating earthquakes and tsunamis, these mammoth industrial disasters have become all too real lately.<\/p>\n<p>On May 21, a disaster was averted at GKN Aerospace in Garden Grove, where a chemical tank with thousands of gallons of methyl methacrylate began to overheat. On May 22, about 25,000 gallons of crude oil began pouring into the busy intersection of Eastern Avenue and Cesar Chavez Avenue in unincorporated East Los Angeles, reaching the L.A. River and killing birds and unleashing a major rescue operation. The Lineage cold storage plant caught fire June 17, and hasn\u2019t stopped burning since, sending plumes of PM2.5 smoke throughout inland parts of L.A. County.<\/p>\n<p>East Los Angeles and Boyle Heights \u2014 Latino-majority neighborhoods \u2014 got the brunt of the last two events. East L.A. is also where residents suffered for years from the fumes and toxic emissions from the now-bankrupt Exide Technologies plant in Vernon.<\/p>\n<p>\u201cThe people of East L.A. have seen this before,\u201d said First District L.A. County Supervisor Hilda Solis, who was at a church in the  unincorporated community, helping hand out masks and air purifiers. \u201cThe people of East L.A. are much more resilient than I am; they\u2019ve had to weather so much in the past decades and now six days ago.\u201d<\/p> <div>\n<\/div>\n<p>Because of those cooling, onshore breezes, the particle pollution will flow into East L.A. and all of the San Gabriel Valley, along with Downey and Norwalk to the southeast and a part of Glendale to the northwest, according to the South Coast Air Quality Management District  advisory.<\/p>\n<p>Though there is not a shelter-in-place order, the smoke has arrived in these areas since Sunday, including parts of the San Fernando Valley. Those areas closer to the fire burning in a set of buildings in the 1400 block of South Los Palos Street experienced \u201cVery Unhealthy\u201d conditions that day in Boyle Heights, while these areas had air \u201cUnhealthy for Sensitive Groups,\u201d (like those who are pregnant, have asthma or the elderly): most of the San Gabriel and Pomona\/Walnut valleys, East San Fernando Valley, West San Fernando Valley, Santa Clarita Valley and parts of San Bernadino County. Other areas, mostly along the coast, had \u201cGood\u201d or \u201cModerate\u201d air quality, the AQMD reported.<\/p>\n<p>Monday night and all day Tuesday, the San Gabriel Valley will get it, mostly as \u201cUnhealthy for Sensitive Groups.\u201d<\/p>\n<p>\u201cThe onshore winds blow everything to the mountains but in the San Gabriel Valley, it has nowhere to go, so it stays there. So Pasadena area will be the worst (outside of Boyle Heights and East L.A.),\u201d Zhu said.<\/p> <div>\n<\/div>\n<p>And that includes Altadena, where 70% of the town burned to the ground during the Eaton fire of Jan. 7 to 8, 2025.<\/p>\n<p>\u201cThe mental health aspect is real, especially for those who experienced the fires previously. We are encouraging folks to stay indoors, use their purifiers, and check on vulnerable neighbors,\u201d said Nic Arnzen, a member of the Altadena Town Council.<\/p><p>Read more <a href=\"https:\/\/siliconvalleymovingpost.com\/?p=17074\">Authorities arrest 2 more suspects in planned attack on Trump\u2019s UFC show<\/a><\/p>\n<p>Arnzen and his husband lost their home in the Eaton fire.<\/p>\n<p>Deputy Chief Derrick Chapman of the L.A. County Fire Department, which has been assisting the LAFD, shared some good news during a press conference Monday.<\/p>\n<p>\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" alt=\"\" class=\"wp-image-17081\" height=\"1024\" src=\"https:\/\/siliconvalleymovingpost.com\/wp-content\/uploads\/2026\/06\/45436e5f1c4a2be708b493c11baa3c82-676x1024.webp\" width=\"676\" srcset=\"https:\/\/siliconvalleymovingpost.com\/wp-content\/uploads\/2026\/06\/45436e5f1c4a2be708b493c11baa3c82-676x1024.webp 676w, https:\/\/siliconvalleymovingpost.com\/wp-content\/uploads\/2026\/06\/45436e5f1c4a2be708b493c11baa3c82-198x300.webp 198w, https:\/\/siliconvalleymovingpost.com\/wp-content\/uploads\/2026\/06\/45436e5f1c4a2be708b493c11baa3c82.webp 731w\" sizes=\"auto, (max-width: 676px) 100vw, 676px\" \/><\/figure>\n<\/p>\n<p>While scientists such as Zhu and other experts were worried about the presence of anhydrous ammonia (NH\u2083), which is used for keeping goods very cold, burning in the fire. Chapman, however, said that the LAFD, on the third day, removed all of the ammonia to an off-site location.<\/p>\n<p>Still, Zhu said the concern is, what components are in PM2.5? Each fire has different kinds of combustion, leading to different kinds of PM2.5. For example, Caltech scientists traced spikes in lead levels in PM10 and PM2.5 from the Eaton fire.<\/p>\n<p>She wants to see more study of the smoke and ash, instead of just lumping it all in as PM2.5.<\/p>\n<p>\u201cFor fires like this, we don\u2019t know what has been created with high combustion,\u201d Zhu said. \u201cThe lessons we learned from the January L.A. fires is we don\u2019t look for (components) specifically. And for this fire, we don\u2019t have the understanding of what we should be looking for.\u201d<\/p>\n<p>As in the Eaton fire that burned electric cars, EV batteries and solar panels, as well as older homes with interiors covered in lead paint, an industrial fire may produce smoke and ash with toxic chemicals hidden unforeseen in the tiny smoke and ash.<\/p>\n<p>\u201cWe need to take precautions. We can\u2019t take this lightly. There are lots of unknowns,\u201d Zhu said.<\/p>\n<p>For those who see hazy, smoky air or smell smoke, Dr. Muntu Davis, with the L.A. County Department of Public Health, said people should stay indoors. They can run air conditioners that circulate air but do not run swamp coolers or fans in windows that pull in outside air.<\/p>\n<p>He warned that weather patterns can shift.<\/p>\n<p>\u201cIt changes hour by hour. So, really pay attention to where you are and what you are seeing outside,\u201d Davis said.<\/p>\n<p>The DPH also recommend:<\/p>\n<p>\u2022 Limit outside exposure. For outdoor workers, wear an N95 or P100 mask.<\/p>\n<p>\u2022 Keep windows and doors closed.<\/p>\n<p>\u2022 If it\u2019s too hot indoors, go to the movies or the library. Cooling shelters will open shortly, L.A. County officials reported.<\/p>\n<p>\u2022 Run your air conditioner or your air purifier<\/p>\n<p>\u2022 Avoid using fireplaces, candles or vacuums.<\/p>\n<p>\u2022 Clean dusty surfaces with a damp cloth and don\u2019t smoke.<\/p>\n<p>\u2022 If you experience symptoms like severe coughing, shortness of breath, wheezing, chest pain, palpitations, nausea, or unusual fatigue, contact your doctor or go to urgent care. For life-threatening symptoms, call 911.<\/p>\n<p>\u2022 Residents who need assistance should call 211 for information on cooling centers, where to find masks or air purifiers.<\/p><p>Read more <a href=\"https:\/\/siliconvalleymovingpost.com\/?p=17072\">A plan to sell artifacts from the Titanic faces US government opposition<\/a><\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>What&#8217;s in the smoke from the East LA warehouse fire?
