The supplied cryostat of the magnet system was designed and manufactured according best available technical knowledge and practice, archived in over 50 years of experience of Bruker BioSpin AG. International standards for quality and approval recommended for cryostats of superconducting magnets were certified.
Customer Responsibilities The customer of the magnet system must obey the security advice and the rules for safety, accident prevention and environmental protection correctly for the magnet systems. Furthermore, the customer is responsible for keeping the magnet system in correct technical condition. In particular: •...
Key Words DANGER Indicates a hazardous situation which, if not prevented, will result in death or serious injury. WARNING Indicates a hazardous situation which, if not prevented, could result in death or serious injury. CAUTION Indicates a hazardous situation which, if not prevented, may result in minor or moderate injury.
Work must only be carried out by approved persons with applicable qualifications. The necessary qualifications are specified in the beginning of the relevant chapter. • In case of doubt, contact Bruker Service. Contact information see page 9 of this document. 2.4.2 Intended Use WARNING Risk of damage to life and limb by incorrect use of the magnet system.
2.4.3 Safety Devices WARNING Risk of damage to life and limb due to not sufficient safety devices. Several safety devices ensure safe operation of the magnet system. They must always be in correct working condition. Thus: • Do not block safety devices. •...
Thus: • Maintain signs and labels in a readable state. • Replace damaged or not readable signs and labels immediately. New signs and labels can be obtained from Bruker Service. 2.4.6 Technical Risks Magnetic Field WARNING Risk of damage to life and limb due to high magnetic fields.
Page 19
Liquid and gaseous cryogenic agents are extremely cold. Contact with liquid or gaseous cryogenic agents will lead to cold burns. Thus: • Only use cryogenic agents in well ventilated rooms. In case of doubt ask Bruker Service. • Wear an oxygen monitor on the body during service and maintenance work.
Page 20
The evaporating helium will displace oxygen. In case of not sufficient ventilation this may result in death by suffocation. Thus • The magnet system site must be well ventilated. In case of doubt contact Bruker Service. • The evaporating gas may resemble smoke. Never pour water on the magnet system.
Page 21
Low Temperatures WARNING Risk of injury due to low temperatures of liquids and metal parts. Physical contact with extremely cold liquids and metal parts may cause serious inju- ries. Contact with the skin may cause cold burns. Contact with the eyes may cause blindness.
Page 22
Risk of Tilting WARNING Risk of injury due tilting of the magnet system. The magnet system is very sensitive to lateral forces. It may tilt. Thus: • Do not climb onto the magnet system. • Do not lean items against the magnet system. •...
2.4.7 Cautions CAUTION Risk of injury and property damage due to incorrect transportation. The box may tilt, movement may get out of control. Thus persons may get injured and the cryostat or further equipment may be damaged. Thus: • Do not move arbitrarily. •...
Personal Protective Equipment The personal protective equipment must be worn at any time while working on the magnet system and to avoid health hazards. Protective Goggles Used to protect the eyes from injury due to flying cold liquids and parts. Protective Gloves Used to protect the hands from injury caused by contact with extremely cold liquids or surfaces and for protection from injury caused by rough edges.
Description of Signs and Labels Signs and labels are always related to their immediately vicinity. The following signs and labels are found on the magnet system and in the vicinity. Prohibition sign: No person with pacemakers! People with pacemakers are endangered in the identified area of 0.5 mT (5 Gauss) and are not allowed to enter these areas.
Safety Devices The cryostat of the supplied magnet system is equipped with the following safety devices: 1 Quench Valves 2 Bursting Disc 3 Safety Valve 4 Drop Off Plate Figure 2.1: Safety Devices of the Cryostat Quench Valve The quench valves (1) are the safety devices of the helium vessel. They open with a defined pressure.
Behavior in Danger and Emergency Situations Preparations • Keep the emergency exits free at all times. • Prepare and maintain an up-to-date list of emergency telephone numbers in the magnet system area. In Case of Emergency • Leave the danger zone immediately. •...
Transportation The transportation is carried out by Bruker Service or approved persons. However, it may happen that other persons have to receive the delivery of the shipping boxes. In this case it is essential to obey the instructions in this chapter and to inform these persons before.
Contact Bruker Service before installation. The claim for damage expires after the fixed period Thus: Report damages to Bruker Service immediately after detection of damage. For contact information see page 9 of this document. ZTKS0160 / Z31926 / Rev.: 00...
Transportation by Fork Lift / Pallet Jack Recommended for transporting the boxes to the installation site. Persons in charge: Approved forklift / pallet jack operator Precondition: The fork lift / pallet jack must be approved for the transportation weight (see chapter Appendix, Technical Data). Transport Check the route of transport for the minimal height and width.
Transportation with a Crane Recommended for lifting the cryostat out of the box. Persons in charge: Approved crane operator Precondition: The crane must be approved for the transportation weight (see chapter Appendix, Technical Data). Attachment Points Exclusively use the marked eyelets (1) as attachment points for the lifting equipment.
Storing If it is necessary to store the cryostat and accessories before installation obey the follo- wing instructions: • Store the boxes in a closed, dry and dust-free room. • Store the boxes upright. • Do not tilt the boxes. •...
