The BSMS/2 systems degree of protection against electrical hazard complies with IEC 61010-1, i.e. all electrical parts are protected against touching. WARNING: All electrical connectors must be used as supplied by BRUKER. Do not substitute them by other types. Lifting the BSMS/2 Chassis WARNING: At least two people are needed to insert and remove the BSMS/2 chassis from the electronics cabinet.
The amplifier in AVANCE NEO systems can only be switched off through the PDU. It is not advised to selectively switch off the amplifier. Instead, shutdown the console completely. Only if otherwise instructed by Bruker personnel, you may be guided through a process to selectively shutdown the amplifier.
It is the intention of Bruker’s customers to communicate effectively the information in this manual regarding safety procedure and hazards associated with NMR magnet systems to their own customers and to users of the equipment.
Magnet Safety 4.1.1 Shielding Most of the newer NMR magnet systems are actively shielded. The following must be understood when installing or working with such a shielded magnet: • The active shielding of the superconducting coil reduces the stray magnetic fields, and therefore its effects.
Magnet Safety 4.1.5 Before Ramping the Magnet to Field Prior to start energizing the magnet system, one must: • Ensure all loose ferromagnetic objects are removed from within 5 gauss field of the NMR magnet system. • Display magnet warning signs at all points of access to the magnet room. •...
Magnet Safety The following figure shows the recommended layout of the warning sign: Safe Handling of Cryogenic Substances A superconducting magnet uses two types of cryogens, liquid helium and liquid nitrogen. Cryogenic liquids can be handled easily and safely provided certain precautions are obeyed. The recommendations in this section are by no means exhaustive, and when in doubt the user is advised to consult the supplier.
Magnet Safety 4.3.2 General Safety Rules General safety rules for handling cryogenic substances include, but are not limited to: • Cryogenic liquids remain at a constant temperature by their respective boiling points and will gradually evaporate, even when kept in insulated storage vessels (dewar). •...
Magnet Safety 4.3.6 Protective Clothing Protective clothing rules include, but are not limited to: • Protective clothing must be worn mainly to avoid cold burns. Therefore dry leather or cryogenic gloves must be worn when handling or working with cryogenic liquids. •...
Magnet Safety 4.4.1 Condensing Oxygen Minimize contact with air. Be aware of the following facts and precautions, contact with air occurs: • Since liquid nitrogen is colder than liquid oxygen, the oxygen in the air will condense out. • If this happens for a period of time, the oxygen concentration in the liquid nitrogen may become so high that it becomes as dangerous as handling liquid oxygen.
Magnet Safety 4.5.1 The Helium Vessel The superconducting NMR magnets contain an inner vessel with liquid helium. • The helium vessel should be checked weekly for boil-off and helium level. • Use a helium flow meter or a helium gas counter! •...
Magnet Safety 4.6.1 Ventilation During Normal Operation Superconducting magnets use liquid nitrogen and liquid helium as cooling agents, and a boil- off of liquid cryogens is expected during the normal operation of the magnet system, as follows: • Normal boil-off of liquids contained in the magnet based on the given boil-off specifications.
Magnet Safety Quench Pipe This solution is based on a pipe connected directly to the magnet, which is then routed to the outside of the building. It is important to note the following: • Ideally, the helium exhaust from the magnet should be vented directly to the outside of the building in case a quench occurs.
Probe Safety Considerations Probe Safety Considerations BRUKER probes are designed to hold the sample, transmit radio frequency signals which excite the sample and receive the emitted response. The transmission and reception is achieved by using specially designed RF coils. The probe is inserted into the bottom of the magnet and sits inside the room temperature shims.
Probe Safety Considerations General Safety Issues • NMR laboratories should not be accessible to the public. Make sure access is restricted to authorized and qualified persons only. • Strong magnetic fields involve various hazards. The danger zone should be labelled as precise as possible by the use of barriers, floor-taping or visual warning devices.

For additional CryoProbe safety and related information, refer to the CryoProbe System User Manual (P/N Z31551), available on the BASH DVD or from Bruker.
CryoProbe Safety Personnel Safety Issues All persons who work with or in the close vicinity of an NMR system must be informed about its safety issues and emergency procedures. If in doubt: Wear goggles and protective gloves, particularly when handling samples! Inherent Safety An NMR system, including its components, is designed for inherent safety.
Electrical Safety The CryoCooling Unit’s degree of protection against electrical hazard complies with IEC IP20: all electrical parts are protected against touching. WARNING: All electrical connectors must be used as supplied by BRUKER. Do not substitute them with other types. H171764_6_001...
CryoProbe Safety Equipment Safety CAUTION: • Do not bend the CryoProbe. Do not hold the CryoProbe at its upper tube, always carry it at its body. • Do not open the CryoProbe. There are no user-serviceable parts inside. A CryoProbe cannot be sealed or reassembled without special equipment.
For additional Prodigy safety and related information, refer to the CryoProbe Prodigy System User Manual (P/N Z31986), available on the BASH DVD or from Bruker. As the CryoProbe Prodigy system is used in conjunction with a magnet system, also refer to Magnet Safety [} 21]...
CryoProbe Prodigy Safety Magnetic Stray Field When working within the 0.5 mT (5 Gauss) stray field of the magnet, all magnetic parts and tools must be avoided or handled with great care. CAUTION: Deposit mechanical watches and cards with a magnetic strip (e.g. credit cards) outside the 0.5 mT (5 Gauss) range of the magnet.
