  • Page 17: Warning

    Contact with the eyes may cause blindness. Refer to Warning: Low Temperature on page 21. 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 18: Gas Under Pressure

    The evaporating helium will displace the breathing air. 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 19: Low Temperatures
