Nitrogen, Compressed (Tec)

SECTION 2: Hazards identification

Nitrogen cylinders may be stacked horizontally provided that they are Main Hazards firmly secured at each end to prevent rolling. Use a "first in - first out" All cylinders are portable gas containers, and must be regarded as inventory system to prevent full cylinders from being stored for pressure vessels at all times. Nitrogen does not support life. It can act excessive periods of time. Keep out of reach of children. as a simple asphyxiant by diluting the concentration of oxygen in air 8 EXPOSURE CONTROLS/PERSONAL PROTECTION below the levels necessary to support life. Adverse Health Effects Occupational Exposure Hazards Inhalation of nitrogen in excessive concentrations can result in As nitrogen is a simple asphyxiant, avoid any areas where spillage dizziness, nausea, vomiting, loss of consciousness and death. has taken place. Only enter once testing has proved the atmosphere Chemical Hazards to be safe. Nitrogen is relatively inert to most materials under ordinary conditions. Engineering Control Measures It becomes more reactive at elevated temperatures, and combines Engineering control measures are preferred to reduce exposure to with hydrogen, oxygen and some metals.

Vapour Inhalation Ensure that sufficient fresh air enters at, or near floor level. As nitrogen acts as a simple asphyxiant death may result from errors Personal Protection in judgement, confusion, or loss of consciousness which prevents self- Self-contained breathing apparatus should always be worn when rescue. At low oxygen concentrations, unconsciousness and death entering area where oxygen depletion may have occurred. Safety may occur in seconds without warning. goggles, gloves and shoes or boots should be worn when handling cylinders.
