  • Page 88: Appendix A Handling Liquid Nitrogen

    Handling Liquid Nitrogen Appendix A Warning Contact of liquid nitrogen or cold gas with the skin or eyes may cause serious freezing (frostbite) injury. ▲ Handle liquid nitrogen carefully. The extremely low temperature can freeze human flesh very rapidly. When spilled on a surface the liquid tends to cover it completely and intimately, cooling a large area.
  • Page 89 Appendix A Appendix A Handling Liquid Nitrogen Handling Liquid Nitrogen Introduction The safe handling and use of liquid nitrogen in cryogenic refrigerators and dewar flasks is largely a matter of knowing the potential hazards and using common-sense procedures based on that knowledge. There are two important properties of liquid nitrogen that present potential hazards: 1.
  • Page 90 Appendix A Handling Liquid Nitrogen Use proper transfer equipment. Use a phase separator or special filling funnel to prevent splashing and spilling when transferring liquid nitrogen into or from a dewar or refrigerator. The top of the funnel should be partly covered to reduce splashing.

  • Page 92: Appendix B Handling Liquid Co

    Handling Liquid CO Appendix B Warning High concentrations of CO gas can cause asphyxiation! OSHA Standards specify that employee exposure to carbon dioxide in any eight- hour shift of a 40-hour work week shall not exceed the eight-hour time weighted average of 5000 PPM (0.5% CO ).

  • Page 93: Appendix C First Aid

    First Aid Appendix C If a person seems to become dizzy or loses consciousness while working with liquid nitrogen or carbon dioxide, move to a well-ventilated area immediately. If breathing has stopped, apply artificial respiration. If breathing is difficult, give oxygen. Call a physician. Keep warm and at rest.
