Section 2
SECTION 2: Hazards identification
Main Hazards: Extremely cold liquid (-196οC) can cause severe frostbite and cold burns. Nitrogen gas can act as an asphyxiant as it dilutes the concentration of oxygen in air below the levels necessary to support life. Rescue workers may require self-contained breathing apparatus and protective clothing. Adverse Health Effects: Inhalation of nitrogen in excessive concentrations can result in dizziness, nausea, vomiting, loss of consciousness, rapid breathing, asphyxiation without warning and death. Skin and Eye Contact: May cause severe cold burns and frostbite. Biological Hazards: Contact between the skin and liquid Nitrogen or uninsulated piping or vessel containing it, can cause severe cold burn injuries.
Environmental hazards
No known effects to the environment, but in confined space ensure adequate ventilation. Chemical Hazards. Nitrogen is relatively inert to most materials under ordinary conditions. It becomes more reactive at elevated temperatures when it combines with hydrogen, oxygen and some metals. __________________________________________________
