Safety Data Sheet

Nitrogen N50 (N₂) is a very pure gas with a purity of ≥ 99.999 %. It is colourless, odourless, tasteless and non-toxic, and is an inert gas – meaning it does not react easily with other substances under normal conditions. Nitrogen N50 is non-flammable and does not promote combustion, making it safe and versatile, especially in demanding industrial processes.

Nitrogen is the most abundant gas in the atmosphere, accounting for about 78%. It is slightly lighter than air and forms a significant part of the Earth’s atmosphere.

Chemical symbol for nitrogen: _N2
Nitrogen UN number: 1066 (nitrogen, compressed), 1977 (nitrogen, refrigerated liquid)
Valve: DIN 477 No. 10 RPV
Density of nitrogen: 1,251 ^kg/m3
Nitrogen relative density (air=1): 0,97 (air=1)
Boiling point of nitrogen at 0,101 mpa: -196°C
Nitrogen reactivity in welding: Typable

Risk of suffocation
An increase in the nitrogen concentration in the air you breathe poses a risk of suffocation. Asphyxiation occurs unnoticed and can be fatal. The nitrogen vaporised from the liquid is very cold. Cold nitrogen vapours are heavier than air and can accumulate in drains and basements, causing elevated nitrogen levels in the premises.

First aid
A person suffering from oxygen deficiency should be immediately moved to fresh air. If the victim is having difficulty breathing or is not breathing, administer artificial respiration as quickly as possible and call for help. When rescuing a victim, it is important to remember not to enter an oxygen-deprived area without breathing equipment.

Frostbite injuries
Liquid nitrogen and its vapours are extremely cold and cause
burns to the skin. Touching uninsulated parts of the equipment with bare skin may cause the skin to catch and tear. In the event of an accident, rinse the heavily damaged areas with lukewarm water and seek medical attention.

Unsuitable materials
Certain materials are unsuitable for use at low temperatures because they become brittle and lose their resistance to impact. Materials normally suitable for use at low temperatures are stainless steel, aluminium and their alloys.

Use

Follow the instructions and safe working practices when handling the substance.
The gas handler must have appropriate training
Use only carefully checked pressure regulators and other operating equipment suitable for this gas. If in doubt, contact Woikoske.
Open the valve slowly to avoid a pressure shock. It takes about one turn to open the bottle.
The valve is opened and closed by hand. The use of assistive devices is prohibited!
The gas cylinder in use must be properly secured
Keep the valve outlets clean!
Close the bottle valve after each use and when the bottle is empty.
Always report a damaged valve and bottle to Woikoske

Transport

The driver must be aware of the potential dangers of the load and know his duties in the event of accidents and incidents.
Liquid nitrogen must be carried in vehicles with an isolated luggage compartment from the cab.
Cylinders should be transported in an upright position
The load must be secured
Bottles must not be knocked, thrown or dropped from the platform of the car
Attention to ADR regulations in transport

Storage

Comply with all legal and local requirements for cylinder storage
Store bottles in a well-ventilated place
Gas cylinders should not be stored in conditions that promote corrosion
Gas cylinders are stored upright and secured so that they cannot fall over.
The valve guard must be in place ALWAYS
Keep empty and full bottles separate
