    Operation of Superconducting Magnets, available from Bruker. Transport and Rigging Safety The following safety notices pertain to the transport and rigging of Avance systems: • The magnet should always be transported gently in an upright position. • The magnets are sensitive to shocks and tilting, thus are fitted with shock and tilt watches during transportation.

  • Page 11: The 0.5 Mt (5 Gauss) Line

    We are not aware of other special guidelines for pregnant workers concerning magnetic fields, when compared to other people. Bruker takes a conservative approach and recommends that all pregnant workers should stay outside the 0.5 mT (5 Gauss) line, which is known as a general guideline for public access.

  • Page 12: Standards On Health And Safety In The Workplace

    Safety 2.2.4 Standards on Health and Safety in the Workplace Guidelines on Limits of Exposure to Static Magnetic Fields are introduced by the ICNIRP (International Commission on Non-Ionizing Radiation Protection). They give separate guidance for occupational exposures and exposure of general public. Occupational Exposures It is recommended that occupational exposure of the head and the trunk should not exceed a spatial peak magnetic flux density of 2 mT (20 Gauss) except for the following circumstance:...

  • Page 13: Table 2.1: Bgv B11 Standards For Standard Precautions And Users

    Safety German Regulations In Germany, regulation BGV B11 describes the maximum exposure doses in two basic tables. Table 2.1 applies to situations under the standard precautionary conditions, whereas Table 2.2 applies to systems with field strengths above 5 Tesla and can only be applied to certain subgroups of people, which meet nonstandard precautionary conditions.

  • Page 14: Ventilation

    Safety Ventilation Typical NMR superconducting magnets use liquid cryogens as cooling agents. During normal operation of the magnet system it can be expected that a boil-off will occur: • A normal boil-off of liquids contained in the magnet will occur based on the established boil-off specifications.

  • Page 15: Oxygen Level Sensors

    Safety 2.3.3 Oxygen Level Sensors Oxygen (O ) monitors, or level sensors, are required in the magnet room to detect low levels of O due to cryogenic gases. At a minimum the following sensors must be provided: • One oxygen level sensor must be above the magnet, to detect low oxygen levels caused by high helium gas levels.

  • Page 16: Liquid Helium Refills

    Helium refills are not required during the normal operation given that there is no helium loss. Helium top-offs or refills are to be done by Bruker engineers, these are needed during cryocooler and helium compressor services and in case of power or cooling water failures if no back-up utilities are present.

  • Page 17: Safety From Nearby Construction

    Safety Safety from Nearby Construction In a magnet system hazards come basically from two sources: • Mechanical breakdown of the mounting suspension in the magnet system. • Quench as a result of mechanical movement of the superconductor and as a result the magnet reaching a critical temperature.

  • Page 18: Fire Department Notification

    Safety 2.8.1 Fire Department Notification It is recommended that the magnet operator introduce the fire department and/or local authorities to the magnet site. It is important that these organizations be informed of the potential risks of the magnet system, e.g. that much of the magnetic rescue equipment (oxygen-cylinders, fire extinguishers, axe's etc.) can be hazardous close to the magnet system.

  • Page 61: Compressed Air System

    Utility Requirements 8.3.4 Compressed Air System When designing a suitable compressed air system the following points must be taken into consideration: • To prevent magnetic impurities from entering the magnet use only copper or stainless steel lines. Do not use iron or steel pipes. Plastic piping is unsuitable where very low dew points are required.

  • Page 62: Air Compressors

    The plastic tubing used to carry the supply from the final gate valve to the console has an outside diameter of 8 mm and is supplied by Bruker. • Some types of dryers, e.g., absorption dryers can use up to 25% of the air flow to regenerate the drying material.

    Utility Requirements 8.3.4.2 Dryers Refrigeration Dryers This type of dryer removes moisture from gas by cooling to within a few degrees of the freezing point of water.

  • Page 66: Table 8.4: Maximum Humidity In The Nmr Laboratory

    Utility Requirements The maximum humidity in the lab depends on the room temperature. There are parts on or near the NMR spectrometer and the magnet system (like the nitrogen heat exchangers) which have temperatures of 14…16°C. When the room temperature is 25°C, with a humidity of 80 %, the dew point of this air is at 21.3°C.

    CryoProbe and Other Accessories 10.2.2.2 Outdoor Helium Compressors The outdoor helium compressor has an outdoor and an indoor unit. Each component has space requirements for airflow and servicing. The indoor component requires a space of 0.5 m (width) x 1.3 m (depth) x 1 m (height). The outdoor component requires a space of 1.4 m (width) x 1.7 m (depth) x 1.25 m (height), and should be sited on a concrete slab.
