安全守則

Bruker NMR Instrument Room - User: Safety and Health Guidelines

1. Personal Protective Safety:

According to environmental safety regulations, users carrying NMR tubes and operating NMR instruments must wear safety goggles to prevent accidents.

2. Medical Implant Safety:

Individuals with pacemakers or metallic heart valves are strictly prohibited from entering the NMR instrument room.

Those with metal implants such as stents, prostheses, and joints must stay away from magnets to ensure their safety.

3. Magnetic Field Safety:

Do not bring ferromagnetic objects and tools near the magnet to avoid quenching, which can damage the superconducting magnet.

Ferromagnetic objects and tools include: steel cylinders, iron rulers, iron tape measures, magnets, magnetic stones, paperclips, binder clips, screws, hairpins, nails, wrenches, hammers, wheels, carts, scissors, vacuum cleaners, iron chairs (iron legs), screwdrivers, blades, flashlights, mobile phones, credit cards, cameras, and analog watches, etc.

Always remember: The superconducting magnet continuously maintains its magnetic force (magnetized state).

4. Cryogenic Liquid Safety:

If the NMR instrument experiences quenching, large amounts of cryogenic liquid helium (4.2K, -269°C) and liquid nitrogen (77K, -196°C) will escape as gas. Personnel inside the room must immediately leave to avoid asphyxiation.

Note: Avoid shaking the NMR magnet and do not touch the magnet without permission.

5. NMR Tube Safety:

NMR tubes have thin walls. When inserting into the rotor, hold the middle section of the NMR tube with your fingers, rotate the tube while inserting it into the rotor (the rotor remains stationary) to avoid tube breakage.

Note: If an NMR tube breaks inside the instrument probe, notify the manager immediately.

6. Computer Maintenance Safety:

Do not use USB flash drives without permission, and do not log out of the shared account (Default User) arbitrarily to prevent network data transmission and hard disk storage failures.

Bruker NMR 儀器室使用者：安全衛生使用守則

Ø   個人防護安全：

依環安衛規定，持 NMR 試管及測 NMR 的使用者必需配戴安全護目眼鏡防止意外發生

Ø   醫療植體安全：

配戴心率調整器、金屬心臟瓣膜者絕對禁止進入 NMR 儀器室

體內植有金屬替代品如支架、義肢及關節等注意遠離磁鐵以維護生命的安全

Ø   磁場安全：

具鐵磁性物件及工具勿靠近磁體，以免超導磁鐵發生淬磁而毀損

鐵磁性物件及工具如：鋼瓶、鐵呎、鐵捲呎、磁鐵、磁石、迴紋針、燕尾夾、螺絲、髮夾、鐵釘、板手、鐵鎚、輪子、推車、剪刀、吸塵器、鐵椅(鐵腳)、起子、刀片、手電筒、手機、信用卡、相機及指針式手錶等等

永遠記住：超導磁體隨時維持磁力無邊(充磁狀態)

Ø   超低溫液體安全：

NMR 儀器若發生淬磁情況，磁體中大量的低溫液氦 4.2K (-269℃) 及液氮 77K (-196℃) 會以氣體散逸出來，室內人員需迅速即刻離開儀器室以免窒息

注意：NMR 磁體忌搖晃，不得隨意觸碰磁體

Ø   NMR試管安全：

NMR 試管其壁薄，套入轉子時，以手指握 NMR 管子的中段處，邊旋轉試管邊塞入轉子(轉子固定不動)，以避免試管破裂

注意：NMR 試管破裂於儀器探頭內時，務必通知管理人員

Ø   電腦維護安全：

未經同意不得使用隨身碟，不得任意登出共用帳戶 (Default User)，以免網路數據傳輸及硬碟儲存失效
