Specification of Nitrogen (N2) Gas And Liquid
Nitrogen (N2) Gas And Liquid
Nitrogen is an element that is at a temperature and pressure gaseous atmosphere. Nitrogen in the air less than 79% by volume. Nitrogen gas having inert properties. Nitrogen gas is widely used as material flow testing, calibration, plastic forming, purging,

2. Hazards
• Causes choke (Asphyxiant) at high concentrations.
• Nitrogen Gas in bottles of high-pressure steel.
• In liquid form if exposed to the skin can cause severe burning and damage to body tissue.
3. Safety
• Keep away from sources of ignition steel bottles and fireworks.
• Do not alter or remove any signs that used for clues contents.
• In disallow use of nitrogen as a buffer steel bottle roller.
4. Moving and Storage
displacement
• Close the steel bottles should be closed.
• Not to be in the drop, clash with one another, receiving the shock, and dragged.
• Lowering the steel bottles of the truck must be given a wooden or rubber pads.
• Removal of steel bottles should use the stroller, in which steel bottle in an upright state.
Storage
• Do not deviate Nitrogen steel bottle close to the flame and other heat sources because it will result in increasing pressure in steel bottles.
• Storage of empty steel bottles and bottles containing steel must be separated.
• Steel Bottles should be stored in a safe place to vibration or other causes which lead terjatuhnya steel bottle.
• Close the steel bottles should be installed properly.
• Steel Bottles should be stored in a dry room with good ventilation and away from substances that are corrosive.
• In a steel bottle empty save all valve must be closed
• storage place in a set of protective devices provide heating.
5. Rescue Measures
* Against the danger of suffocation:
• Move the victim to place free valve.
• Give CPR.
• Bring kerumahsakit nearby.
• Against leakage steel bottle.
• Move to the place of steel bottle open
• If exposed to liquid nitrogen in the body, flush with water as much as possible.
