洛杉矶博伊尔高地仓库大火持续释放浓烟Boyle Heights Warehouse Fire Spreads Heavy Smoke Across Los Angeles
自周三起，洛杉矶博伊尔高地一座占地50万平方英尺的Lineage Big Bear冷库设施发生火灾，持续向洛杉矶地区释放浓烟和异味，促使地方和州政府官员宣布进入紧急状态并发布空气质量警告。洛杉矶消防局局长杰米·摩尔表示，消防员通过调整战术取得了重大进展，已成功将火势控制在建筑的一侧。在灭火行动中，消防部门使用了3000加仑的大型直升机投水和阻燃剂，并在夜间使用挖掘机拆除部分外墙以改善通风，同时引入水炮对先前无法触及的区域进行灭火。由于建筑内目前燃烧的是普通A类可燃物，预计现场产生的浓烟还将持续约三天。整个救援行动正在24小时不间断地进行，以彻底扑灭这起复杂的仓库大火。
A fire that began on Wednesday at the 500,000-square-foot Lineage Big Bear cold-storage facility in Boyle Heights has been spreading heavy smoke and unpleasant odors across the Los Angeles region, prompting state and local officials to declare an emergency and issue air-quality warnings. Los Angeles Fire Department Chief Jaime Moore announced on Sunday that firefighters have made "incredible headway" by altering their tactics and successfully confining the blaze to one side of the large building. To control the fire, crews utilized larger 3,000-gallon water-dropping helicopters, dropped retardant, used excavators overnight to tear off part of the exterior walls for ventilation, and deployed water cannons to reach previously inaccessible areas. Fire officials stated that the fire is now a free-burning blaze involving ordinary Class A combustibles inside the facility, which is expected to continue generating smoke for approximately three more days as crews work around the clock.
01大火持续蔓延烟雾 官方发布空气警告并宣布紧急状态Smoke Spreads Across Los Angeles as Emergency Declared
这起复杂的火灾于周三在洛杉矶博伊尔高地南洛斯帕洛斯街1400号的Lineage Big Bear冷库设施爆发。由于该仓库占地达50万平方英尺且专门用于储存冷冻食品，火势在建筑内部蔓延，导致大量浓烟和令人不适的异味在周日持续扩散至整个洛杉矶地区。面对不断蔓延的烟雾，地方和州政府官员已经宣布进入紧急状态，以调配更多资源应对灾情。
The complex fire erupted on Wednesday at the 500,000-square-foot Lineage Big Bear cold-storage facility, located at 1400 S. Los Palos Street in Boyle Heights. Because the massive building is used to store frozen foods, the interior blaze has been difficult to extinguish, causing heavy smoke and unpleasant odors to spread across the wider Los Angeles region by Sunday. In response to the persistent smoke and the scale of the incident, state and local officials have declared an emergency to coordinate resources.
随着烟雾和难闻的气味笼罩洛杉矶的部分地区，当地居民对空气质量和健康影响提出了诸多疑问。对此，有关部门重申了空气质量警告，提醒受影响区域的居民采取防护措施。尽管洛杉矶消防局表示灭火工作已经取得进展，但由于火势尚未完全扑灭，烟雾对周边社区空气质量的负面影响仍在持续。
As the smoky air and nasty smells blanketed parts of Los Angeles, local residents raised numerous questions regarding health risks and air safety. In response, authorities reiterated their air-quality warnings, urging the public to take necessary precautions. Although the Los Angeles Fire Department reported making progress in containing the blaze, the lingering smoke continues to impact the region's air quality while firefighting operations proceed.

周三下午，洛杉矶博伊尔高地洛斯帕洛斯南街1400号一座占地50万平方英尺的私营冷库设施突发火灾，释放出大量浓烟。
On Wednesday afternoon, a fire broke out at a 500,000-square-foot privately owned cold-storage facility at 1400 South Los Palos Street in Boyle Heights, Los Angeles, releasing heavy smoke.
截至周六，大火仍在持续燃烧。洛杉矶市长凯伦·巴斯与加州州长加文·纽森相继宣布当地进入紧急状态，并发布空气质量警告。
As the fire continued to burn through Saturday, Los Angeles Mayor Karen Bass and California Governor Gavin Newsom declared local emergencies and issued air-quality warnings.
消防部门持续在现场进行扑救，由于建筑物内含有大量普通可燃物，预计烟雾仍将持续数日。

02消防战术调整：直升机投水与阻燃剂控制火势Tactical Shift: Helicopters and Retardant Confine the Blaze
洛杉矶消防局局长杰米·摩尔在周日下午举行的新闻发布会上宣布，消防部门通过改变部分战术，在扑灭这起复杂火灾的过程中取得了重大突破。在调整后的战术中，消防人员启用了容量更大、每次可投放3000加仑水的大型直升机，并向起火建筑投掷了阻燃剂，以强力压制猛烈的火势。
Los Angeles Fire Department Chief Jaime Moore announced during a Sunday afternoon press conference that the department made significant breakthroughs in battling the complex blaze by altering several of their tactics. Under the adjusted strategy, firefighting crews deployed larger helicopters capable of dropping 3,000 gallons of water, while also dropping fire retardant directly onto the burning facility to suppress the intense flames.
在完成这些直升机空中投放作业后，现场消防员开始重新采用传统的灭火方法。摩尔指出，通过将这座占地50万平方英尺的庞大冷库建筑一分为二，救援人员成功将火势局限在建筑的一侧，从而有效阻止了火势在整座设施内进一步蔓延，为后续的地面灭火和清理工作创造了有利条件。这一战术调整使消防员能够更安全地在现场展开后续工作。
Following these aerial operations, firefighters transitioned back to their traditional firefighting methods. Chief Moore noted that by effectively splitting the massive 500,000-square-foot cold-storage building in half, crews successfully confined the active fire to just one side of the structure, preventing it from consuming the entire facility. This tactical shift allowed ground crews to operate more safely as they worked to gain control over the stubborn warehouse fire.
03破拆外墙与水炮作业：攻克无法触及的起火区域Wall Breaching and Water Cannons: Reaching Inaccessible Areas
在夜间救援行动中，现场消防人员采取了更为直接的地面攻坚手段，利用重型挖掘机对起火建筑的部分外墙进行了破拆。洛杉矶消防局指出，这一举措的主要目的是改善庞大冷库设施内部的通风条件，帮助积聚在建筑深处的浓烟和热量向外排出，从而为地面消防员创造更安全的作业环境。
During the overnight operations, firefighting crews implemented aggressive ground tactics by utilizing heavy excavators to tear off portions of the building's exterior walls. According to the Los Angeles Fire Department, this critical step was designed to improve ventilation inside the massive facility, allowing trapped heat and dense smoke to escape and creating safer conditions for the personnel working on the ground.
在完成外墙破拆并改善通风后，消防部门随即引入了重型水炮设备。这些水炮被部署在关键位置，向建筑内部持续喷射高压水流，成功攻克了此前因墙体阻挡和高温而无法触及的起火区域。通过这种破拆与高压喷淋相结合的地面作业，救援人员得以直接打击核心火点，进一步巩固了此前通过空中投水所取得的控制效果。
Following the wall breaches, crews deployed powerful water cannons to target the active flames. These water cannons allowed firefighters to direct high-pressure streams into the building's interior, successfully reaching deep-seated pockets of fire that had previously been completely inaccessible due to the structural barriers. This combination of mechanical breaching and heavy water streams enabled crews to directly suppress the core of the fire.
04普通可燃物持续燃烧 预计烟雾仍将持续三天Class A Combustibles Burning: Smoke Expected for Three More Days
洛杉矶消防局局长杰米·摩尔解释说，随着灭火工作的推进，目前这起火灾已经转变为涉及普通A类可燃物的自由燃烧状态。由于建筑内部目前正在燃烧的是这些普通可燃物，其燃烧产生的正是常规的副产物，这也是现场持续产生大量浓烟的原因。尽管消防人员在控制火势方面取得了重大进展，但这些普通可燃物的持续阴燃意味着烟雾排放仍将维持一段时间。
Los Angeles Fire Department Chief Jaime Moore explained that as the firefighting operations progressed, the incident transitioned into a free-burning fire involving ordinary Class A combustibles inside the facility. Moore noted that because these ordinary combustibles are currently burning, they are producing regular combustion byproducts, which explains why a large volume of heavy smoke continues to be generated from the site.
根据消防部门的评估，现场产生的浓烟和异味预计还将持续大约三天。由于这些普通可燃物在庞大的冷库建筑内部继续燃烧，消防员需要逐步清理并彻底扑灭残留的火点。在此期间，地方官员将继续监测空气质量，并建议受影响区域的居民保持警惕，防范持续烟雾对日常生活和健康带来的不便。
Based on the fire department's assessments, the heavy smoke and unpleasant odors generated by the burning Class A materials are expected to persist for approximately three more days. As these ordinary combustibles continue to burn within the massive cold-storage structure, crews must systematically clear and extinguish the remaining pockets of fire. Local officials will continue to monitor the air quality during this period, advising residents in the affected areas to remain cautious as the smoke lingers.
