A large-scale fire occurred at a commercial cold storage warehouse in the Boyle Heights neighborhood of Los Angeles, necessitating extensive suppression efforts and regional air quality monitoring.

洛杉磯 Boyle Heights 區的一座商業冷藏倉庫發生大規模火災，需要採取大規模撲救行動並進行區域空氣品質監測。

The incident commenced on June 17 at a 500,000-square-foot facility located on South Los Palos Street. The structure's architectural composition—specifically corrugated steel walls containing dense foam insulation and reinforced interior panels—has contributed to the persistence of the blaze, as the insulation sustains slow combustion. Furthermore, the presence of ammonia within the refrigeration systems introduced initial chemical hazards, although the operator, Lineage, asserts that the ammonia has been pumped out and transported offsite, with no measurable concentrations recorded in the community.

該事件於 6 月 17 日發生在位於 South Los Palos Street 一座 50 萬平方英尺的設施中。該建築的結構組成——特別是含有高密度泡沫絕緣層的波 corrugated 鋼牆與強化內板——導致火勢持續，因為絕緣層會產生緩慢燃燒。此外，冷藏系統中的氨氣最初帶來了化學危險，儘管營運商 Lineage 聲稱氨氣已將被泵出並運往場外，社區中未記錄到可測得的濃度。

Operational constraints are significant; zero visibility and structural instability have precluded interior entry by the Los Angeles Fire Department. Suppression tactics have focused on exterior containment via aerial ladder pipes and continuous helicopter water drops. A critical secondary concern involves the potential for a biohazard event, as approximately 85 million pounds of frozen food remain within the facility. The administration is currently evaluating methodologies for the extraction of these goods to prevent spoilage-induced contamination.

行動限制顯著；由於零能見度且結構不穩定，洛杉磯消防局無法進入內部。撲救戰術集中於透過雲梯車與直升機持續灑水進行外部圍截。另一個關鍵次要問題涉及生物災害的潛在風險，因為設施內仍有約 8,500 萬磅的冷凍食物。行政部門目前正在評估提取這些貨物的方法，以防止腐敗引起的污染。

Regarding the etiology of the fire, Lineage has indicated that the ignition likely occurred during testing conducted by third-party contractors on the facility's rooftop solar array. While a shelter-in-place order was previously rescinded, smoke plumes have migrated eastward, affecting air quality in the San Gabriel Valley and reaching as far as West Covina, Ontario, and La Verne. In response, Mayor Karen Bass has coordinated the opening of shelters at the Pecan Recreation Center and City Terrace Park and has sought a joint emergency declaration with Governor Newsom to facilitate the removal of toxic materials and prevent environmental degradation.

關於起火原因，Lineage 指出，起火可能發生在第三方承包商對設施頂樓太陽能陣列進行測試期間。雖然先前已撤銷原地避難命令，但煙霧向東飄移，影響了聖蓋博谷（San Gabriel Valley）的空氣品質，甚至波及至西科維納（West Covina）、安大略（Ontario）和拉維恩（La Verne）。對此，市長 Karen Bass 已協調在 Pecan 休閒中心和 City Terrace 公園開設避難所，並尋求與州長 Newsom 共同發布緊急狀態宣告，以利於移除有毒物質並防止環境惡化。

Containment operations remain ongoing, with officials indicating that full extinguishment may require several days or weeks due to deep-seated smoldering debris.

圍截行動仍在進行中，官員指出由於碎片中存在深層悶燒，完全撲滅可能需要數日或數週。
