Liquid Nitrogen Safety Precautions

• NFPA 255, Standard Method of Test of Surface Burning Characteristics of Building
Materials
OSHA 29CFR1910.103 1910.103 Hydrogen
WARNING Before using hazardous substances (toxic, harmful, and so on), read the
hazard indications and information reported in the applicable Material Safety Data Sheet
(MSDS.) Use Personal protection according to the safety requirements.
When analyzing toxic compounds be aware that during the normal operation of the GC some
of the sample might be vented outside the instrument through the inlet and detector exits;
therefore, make sure to vent the exhaust gases to a fume hood. Consult local Environmental
and Safety Regulations for instructions in exhausting fumes from your system.
Liquid nitrogen is a colorless, odorless, extremely cold liquid and gas under pressure. It can
cause rapid suffocation when concentrations are sufficient to reduce oxygen levels below
19.5%. A Self Contained Breathing Apparatus (SCBA) might be required. Contact with
liquid or cold vapors can cause severe frostbite. Cold vapors in the air will appear as a white
fog due to condensation of moisture. Oxygen concentrations must be monitored in the release
area. All cryogenic liquids produce large volumes of gas when they vaporize.
WARNING Before using Liquid Nitrogen, read the hazard indications and the
instructions reported in the Safety sheet supplied by the manufacturer, with reference to
the CAS number (Chemical Abstract Service) 7727-37-9.
Use personal protection:
• Protective gloves: Loose fitting thermal-insulated or leather gloves.
• Eye protection: Full face shield and safety glasses are recommended.
• Other protective equipment: Safety shoes when handling containers. Long sleeved
shirts and trousers without cuffs. Work clothing that sufficiently prevents skin contact
should be worn.
