FIRST AID MEASURES.
INHALATION: Move person away from the dangerous zone into an area with clean air. Supply oxygen if breathing is
problematic. Seek qualified medical assistance.
CONTACT WITH SKIN: Damage not expected.
INGESTION: This product is a gas under normal temperature and pressure.
CONTACT WITH EYES: Damage not expected.
5. FIRE-FIGHTING MEASURES.
5.1. E x t i n g u i s h i n g media.
Non-combustible gas. In case of fire in the presence of nitrogen, all available fire-fighting means can be used.
5.2. Hazardous combustion products.
None.
5.3. Special hazards.
Evacuate all personnel, not involved with the extinguishing of the fire.
5.4. Special safety equipment for fire-fighters.
Special clothing, resistant to high temperature, gloves, boots, a breathing apparatus (Saturn, Draeger)
LIMITS OF FLAMMABILITY IN AIR, %: not applicable.
6. ACCIDENTAL RELEASE MEASURES.
6.1. Personal precautions.
Use personal safety equipment - special working clothing, gloves, shoes, breathing apparatus. In case of nitrogen
release, immediately evacuate all personnel from the dangerous zone.
If release comes only from one cylinder, take the cylinder outside and let the gas disperse.
Stop the release.
Ventilate area.
6.2. Environmental precautions.
Try to stop release. Take measures against entrance into canals, underground areas, working rooms or other places, where
building up of excess nitrogen can be dangerous.
7. HANDLING AND STORAGE.
7.1. H a n d l i n g .
Use personal safety equipment – special working clothing, gloves, safety goggles or a screen. Prevent cylinder from
damage. Use a suitable cart (trolley, hand truck etc.) to transport the cylinders – do not drag, roll, slide, hit. Never
lift the cylinders without their valve-protection caps – the cap is made only to protect the valve. Never place objects
inside the cap (e.g. wrench, screwdriver etc.) – this may damage the valve and lead to accidental release. Open the
2
valve slowly, to avoid pressure force. If valve is hard to open – stop work and contact your supplier.
7.2. S t o r a g e .
Nitrogen (gas) is stored in steel cylinders and gasholder.
Keep away from ignition and heat sources – heating of the cylinder increases gas pressure. Store
in temperatures lower than 520С. The storage room should be dry and well ventilated, or with
natural ventilation. Full and empty containers should be stored separately. Keep containers from
falling and impact.
OTHER DANGERS DURING WORK, STORAGE, USE:
Gas under high pressure: The gas may cause excessive salivation in case of insufficient oxygen supply. Close the
valve after every use; keep the valve closed, even if container is empty. Avoid the return of flow to the cylinder. This
may cause cracking of the cylinder. When you return the cylinders to your supplier, make sure the valves are closed.
In case of release, close the valve of the cylinder.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION.
8.1. Exposure limits.
Nitrogen is not classified as a dangerous chemical compound. There is no data on exposure limits.
8.2. Exposure control.
Keep away from ignition sources, heat, as heating of the bottle causes an increase in pressure and may lead to an explosion.
Provide reliable ventilation in the storage room.
8.2.1. Control in case of occupational exposure.
Provide natural and/or artificial ventilation to prevent suffocation with nitrogen upon inhalation.
Provide personal protective equipment – special working clothing and shoes, gloves, breathing apparatus (Saturn, Draeger)
Airway protection.
Provision of natural and/or artificial ventilation and a breathing apparatus (Saturn, Draeger).
Hand protection.
Wearing gloves during work is recommended.
Eye protection.
Wearing safety goggles during work is recommended.
Protection of skin and body.
Wear working shoes from natural leather with a metal toe and plate. Wear protective clothing as necessary.
8.2.2. Control of environmental exposure.
Do not discharge into confined spaces, particularly on lower (ground) floors.

Chemical properties
Nitrogen is an extremely inert nonmetal, due to the strong covalent bond between its molecules. It reacts with:
1. Oxygen – direct formation of NO, N2O, NO2, N2O3, N2O5.
2. Hydrogen – forming ammonia (NH3).
3. Metals – at high temperatures – salt (nitride) formation.
Nitrogen has a very low solubility in water.
10. STABILITY AND REACTIVITY.
10.1. Stability.
The product is stable when storage conditions are met.
10.2. Conditions to avoid.
Proximity to heat and fire sources.
10.3. Materials to avoid (incompatibility).
In specific conditions, nitrogen may react with lithium, titanium (above 8000С) and magnesium, forming nitrides. At
high temperatures it also reacts with oxygen and hydrogen.
10.4. Dangerous decay products.
None.
11. TOXICOLOGIC INFORMATION.
Toxicological effects of this product have not been observed.
