化學系各位成員大家好：

115年08月12日中午11:20左右，系上火災警報響起，觸發位置為B棟五樓電氣機房。系辦人員至現場發現設備有濃煙火光，立即通報學校配電室至系館斷電，並同步通報消防隊。斷電後火光消失未進一步擴大災情。系館人員並依疏散程序，疏散至博雅教學館前草坪，各實驗室清點人數後回報總指揮官，本次事件無人員傷亡，消防隊初步認定為偶發電氣事故。

經學校配電站同仁及廠商初步檢查，研判為一處閘刀開關設備異常所致。目前已將相關迴路隔離並停止供電。受影響範圍包括 B 棟 1、3、5、7 樓及頂樓之部分電力迴路，其餘區域目前已陸續恢復供電。
廠商進一步檢查故障設備後，考量該迴路目前重新送電仍有安全風險，因此上述受影響區域將暫時維持停電。系上已請相關單位及廠商儘速安排後續檢修與修復作業，恢復供電時間將視檢修結果另行通知。
停電期間，請受影響區域的師生勿自行操作配電設備或嘗試恢復供電，並請留意實驗設備、冷藏冷凍設備及其他需要持續供電之儀器狀況。如有緊急需求，請與系辦聯繫。
造成不便，敬請見諒，並感謝大家的配合。

化學系辦敬上

Dear all,

At approximately 11:20 AM on August 12, 2026, the fire alarm was activated in the Chemistry Building due to an incident in the electrical room on the 5th floor of Building B. Department staff immediately inspected the location and identified smoke and sparks from the equipment. The university’s power distribution room was promptly requested to cut power to the building, and the fire department was notified simultaneously. Following the power cutoff, the sparks ceased and the situation was contained without further expansion.

In accordance with emergency response procedures, all personnel evacuated to the lawn in front of the Boya Teaching Building. Roll calls were conducted by each laboratory and reported to the incident commander. No injuries were reported, and the fire department preliminarily classified this as an isolated electrical incident.

Initial inspections by power distribution station staff and technicians determined that the issue was caused by a malfunction in a knife switch component. The affected electrical circuit has been isolated and powered off. The affected areas include select power circuits on the 1st, 3rd, 5th, and 7th floors, as well as the rooftop of Building B. Power to all other areas has been gradually restored.

Following further inspection of the damaged equipment, the vendor determined that re-energizing the circuit poses safety risks at this stage. Therefore, power in the aforementioned affected areas will temporarily remain suspended. The department has requested relevant units and technicians to arrange follow-up inspection and repair work as quickly as possible. The timeline for power restoration will be announced once the inspection results are finalized.

During the outage, faculty, staff, and students in the affected areas are kindly reminded not to operate electrical distribution equipment or attempt to restore power independently. Please closely monitor laboratory equipment, refrigeration/freezer units, and other instruments that require continuous power. If you have any urgent needs, please contact the Department Office.

We apologize for the inconvenience and appreciate your cooperation and understanding.

Sincerely,

Department of Chemistry, NTU
