A significant fire occurred Wednesday afternoon at a large-scale cold storage warehouse in the Boyle Heights district of Los Angeles, necessitating emergency containment measures and public safety directives.

週三下午在洛杉磯 Boyle Heights 區的一座大型冷藏倉庫發生嚴重火災，需採取緊急圍堵措施並發布公眾安全指示。

The incident commenced at approximately 14:30 hours at a facility owned by Lineage, comprising nearly 500,000 square feet of temperature-controlled storage. Initial combustion was localized to the roof's solar array. The operational complexity of the response was exacerbated by the structural compromise of an ammonia refrigerant line, resulting in the pressurized release of toxic and flammable gas. This atmospheric contamination prompted Mayor Karen Bass and the Los Angeles Fire Department (LAFD) to implement shelter-in-place protocols for local residents, emphasizing the cessation of HVAC system utilization and the sealing of residential apertures.

事件於約 14:30 發生在 Lineage 擁有的設施中，該設施包含近 50 萬平方英呎的溫控儲存空間。最初起火點位於屋頂的太陽能電板陣。由於氨氣冷媒管路受損，導致高壓有毒且易燃的氣體洩漏，增加了救援行動的複雜性。面對大氣污染，市長 Karen Bass 與洛杉磯消防局 (LAFD) 要求當地居民執行「就地避難」協定，強調必須停止使用 HVAC 系統並密封住宅門窗。

Tactical adjustments were required when the intensity of the blaze overran ground-based suppression efforts, necessitating the deployment of three helicopters for aerial water delivery. The LAFD reported that personnel were momentarily forced to evacuate the immediate vicinity due to the ammonia off-gassing. Furthermore, the presence of solar infrastructure introduced the possibility of lithium-ion battery involvement. LAFD officials identified the potential for 'thermal runaway' within such batteries as a significant contemporary challenge in fire suppression, citing the inherent difficulty in extinguishing these chemical fires and the toxicity of the resulting emissions. By the evening, the roof fire was largely contained, and interior assessments were initiated.

當火勢強度超過地面滅火能力時，救援策略隨之調整，部署了三架直升機進行空中灑水。LAFD 報告指出，由於氨氣洩漏，人員一度被迫撤離立即 vicinity 區域。此外，太陽能基礎設施的存在增加了鋰電池參與火災的可能性。LAFD 官員指出，此類電池的「熱失控」是當前消防工作的一大挑戰，因為化學火難以撲滅且排放物具有毒性。至傍晚，屋頂火勢基本受控，隨後展開內部評估。

The fire has been largely suppressed, and the immediate chemical threat has dissipated, though the cause of the ignition remains under official investigation.

火災已基本撲滅，立即性的化學威脅已消散，但起火原因仍由官方調查中。
