化學系各位成員大家好：

7/4晚上約18:40，A棟三樓某實驗室三位成員（均穿戴實驗衣、護目鏡及手套）在處理廢棄的黑色碳奈米粒子樣品時，因該粉末可能沾有具高活性的奈米金屬觸媒，導致起火。當下已使用滅火器撲滅火勢，隨後由安全官進行現場勘查並確認已無火光，三位同學亦均未受傷。

後續將於實驗室內進行宣導：此類材料須存放於手套箱內，並於手套箱中進行相關實驗；實驗後的廢棄材料及同類廢棄物在移出時須密閉保存，並依環安衛中心規定，申報並依程序清運過期或特殊類別之廢棄藥品，以防止類似事故再次發生。

Dear all,

At approximately 18:40 on July 4th, three members of a laboratory on the third floor of Building A (all wearing lab coats, safety goggles, and gloves) were handling discarded black carbon nanoparticle samples. The powder may have been contaminated with highly reactive nanoscale metal catalysts, which likely caused it to ignite. The fire was promptly extinguished by a fire extinguisher. The safety officer later conducted an on-site inspection and confirmed that no visible flames remained. None of the three students were injured.

As a follow-up, the laboratory will reinforce safety protocols, including: storing such chemicals inside a glovebox and conducting all related experiments within the glovebox; ensuring that any waste materials of this type are sealed before removal; and following EHS center regulations for reporting and properly disposing of expired or special-category chemical waste to prevent similar incidents from occurring in the future.
