俄亥俄州 Toledo 化工储罐泄漏有毒气体：近千人疏散、一名警员受伤 市府决定让罐内反应自行完成

位于美国俄亥俄州 Lucas 县的 Toledo 市北部一座化工储罐10月20日晚发生事故，有毒化学品甲基丙烯酸缩水甘油酯泄漏并以气体形式扩散，市政府连夜下令事发地一英里范围内约983名居民疏散、三英里范围内居民就地避难。市长 Wade Kapszukiewicz 10月21日表示，一名 Lucas 县警长办公室警员在响应事故时受伤、自行驾车前往医院，是目前已知唯一伤者；受损储罐至21日上午仍在排放该化学品，市府决定让罐内化学反应自行完成，泄漏21日下午仍在持续、情况逐步好转。

事发地点为 Progress Avenue 1266 号的 MC Tank Terminal，位于 Toledo 市中心以北约10英里、靠近 I-280 公路。事故发生在20日晚约9时30分：Toledo 消防救援局最初通报一辆罐车发生爆炸，Kapszukiewicz 市长在21日晨间记者会上也称储罐发生爆炸；但市府发言人 Rachel Hart 其后向《今日美国》表示，实际上并未发生爆炸。俄亥俄州环境保护署（Ohio EPA）表示，事故发生在物料转输过程中，储罐容量为5,500加仑；当地电视台 WTOL 报道称，事发时罐内实际存量可能接近3,000加仑。事故原因尚未公布。

MC Tank Transport 公司声明确认，泄漏物质为甲基丙烯酸缩水甘油酯（glycidyl methacrylate），是一种用于塑料、油漆与涂料的工业化学品，常态为液体，本次以气体形式释放。该物质易燃，接触可致眼睛、鼻腔、口腔与皮肤灼痛感，过量吸入可引发头痛、头晕、乏力、恶心与呕吐。Lucas 县地区卫生局局长 Karim Baroudi 在记者会上表示，这种化学品「接触或吞入都有很强的毒性」，当局正检测居民呼吸空气中的毒性水平以便给出更准确的指引；他同时表示，现阶段它「主要是一种刺激物」。市府建议居民关紧门窗、关闭引入室外空气的通风系统，出现症状者先淋浴并联系医疗专业人员。

疏散范围两度扩大：消防部门20日晚先令事发地半英里内约300名居民撤离，随后扩大到一英里内983人；三英里范围内居民须就地避难。美国红十字会在 Toledo 的 Believe Center 设立了可容纳约200人的庇护所。市长表示，储罐在事故后12小时内存在爆炸可能、即至21日上午9时30分左右，应急与危化品队伍在此之前无法接近储罐；联邦环境保护署（EPA）表示，消防部门控制泄漏的尝试未获成功，储罐已受损、罐内化学品正在完成一个反应过程，市府判断最安全的做法是让反应自行完成。市长21日下午更新称情况正稳步改善；据当地电视台报道，反应完成可能还需6至16个小时。

影响已越过州界：密歇根州 Monroe 县 Bedford Township 与 Erie Township 的居民21日上午接到就地避难通知，Bedford 公立学校与 Mason 联合学校停课，Monroe 县社区学院 Whitman 中心关闭。汽车制造商 Stellantis 位于北 Toledo 的 Jeep 组装厂距事发地约一英里，厂区北部20日晚疏散员工，21日第一班与第二班均取消；南部厂区本周本就不生产。Toledo 大学表示校园目前未受已知影响，周六主场对阵 Western Michigan 大学的橄榄球赛按计划举行。

Toxic Chemical Release in Toledo, Ohio Forces Evacuation of Nearly 1,000; Deputy Injured as City Lets Tank Reaction Run Its Course

A chemical tank incident in Toledo, Lucas County, Ohio, on the night of October 20 released the toxic chemical glycidyl methacrylate as a gas, prompting the city to order about 983 residents within a one-mile radius to evacuate and residents within three miles to shelter in place. Mayor Wade Kapszukiewicz said on October 21 that a Lucas County sheriff's deputy was injured responding to the incident and drove himself to a hospital — the only known injury — and that the damaged tank was still emitting the chemical on Wednesday morning. The city decided to let the chemical reaction inside the tank run its course; the release was still ongoing Wednesday afternoon, though the situation was steadily improving.

The incident occurred at the MC Tank Terminal at 1266 Progress Avenue, about 10 miles north of downtown Toledo near I-280, at around 9:30 p.m. on October 20. The Toledo Fire and Rescue Department initially reported that a tanker had exploded, and Mayor Kapszukiewicz also described a tank explosion at a Wednesday morning news conference; city spokesperson Rachel Hart later told USA Today that no explosion had in fact occurred. The Ohio Environmental Protection Agency said the incident happened while material was being transferred, and put the tank's capacity at 5,500 gallons; local station WTOL reported the tank may have held closer to 3,000 gallons at the time. The cause has not been announced.

MC Tank Transport confirmed the released substance was glycidyl methacrylate, an industrial chemical used in plastics, paints and coatings that is stored as a liquid but was released as a gas. The chemical is flammable and can cause burning of the eyes, nose, mouth and skin; overexposure can lead to headache, dizziness, tiredness, nausea and vomiting. Karim Baroudi, commissioner of the Toledo-Lucas County Health Department, said the chemical is highly toxic if touched or ingested and that officials were measuring toxicity levels in the air residents are breathing to give better guidance, while adding that at this stage it is mostly an irritant. The city advised residents to keep doors and windows closed, turn off ventilation systems that draw in outside air, shower and contact a medical professional if symptoms appear.

The evacuation zone expanded twice: firefighters first ordered about 300 residents within a half-mile to leave on Tuesday night, then widened the order to 983 people within one mile, with shelter-in-place in effect within three miles. The American Red Cross opened a shelter with capacity for about 200 people at the Believe Center in Toledo. The mayor said the tank carried a risk of explosion for 12 hours after the incident — until about 9:30 a.m. Wednesday — and responders and hazmat teams could not approach it before then. The U.S. Environmental Protection Agency said fire department attempts to contain the release were unsuccessful, the tank had been compromised and the chemical inside was completing a reaction, and the city determined the safest course was to let the reaction finish. The mayor said Wednesday afternoon the situation was steadily improving; local television reported the reaction could take another six to 16 hours to complete.

Effects crossed the state line: residents of Bedford Township and Erie Township in Monroe County, Michigan, were told to shelter in place on Wednesday morning, Bedford Public Schools and Mason Consolidated Schools closed, and Monroe County Community College's Whitman Center shut for the day. Stellantis's Toledo Jeep Assembly Complex sits about a mile from the site; its north plant evacuated employees on Tuesday night and canceled both the first and second shifts on Wednesday, while the south plant was not scheduled to run this week. The University of Toledo said its campus had no known impact and Saturday's home football game against Western Michigan would proceed as planned.
