Precautionary statement
Warning Gas in pipelines may be under pressure, cylinders may explode if heated May displace oxygen and cause rapid suffocation
Read completely and follow all Safety Data Sheets before use Colorless, odorless gas Never enter an area where nitrogen may have caused an oxygen deficiency Ensure proper ventilation Use equipment and materials rated for service Protect cylinders from sunlight, store in ventilated area Rapid release of compressed gas may cause frostbite if contacted Hazards not otherwise classified None Toxicity (^) Non-toxic but may displace oxygen which can cause dizziness, unconsciousness and death by asphyxiation.
Section 3 โ Compositions / Information of Ingredients Chemical Name & Formula Nitrogen, N Common Name and Synonyms Nitrogen Gas, N2, GAN (Gaseous Nitrogen), Di-atomic nitrogen, Compressed Nitrogen, Food Grade Nitrogen, Nitrogen NF CAS Number 7727-37-9, Nitrogen Compressed Purity Nominally 100%, typically provided >99%, by volume. NOTE: Some on-site nitrogen generated gas can be as low as 95%, with balance being primarily oxygen.

Section 4 โ First Aid Measures Inhalation Simple asphyxiant, may cause acute effects including dizziness, drowsiness, nausea, rapid breathing, unconsciousness, and death. Immediately remove victim to fresh air containing sufficient oxygen. If not breathing provide artificial respiration or oxygen by trained personnel, get immediate medical attention. Rescuers must not enter an oxygen deficient area without self contained breathing apparatus. Skin Contact No adverse effects expected from gas at normal temperature. Very cold gas may cause frostbite. Eye Contact No adverse effects normally expected from gas. Avoid high pressure or very cold gas. Remove contact lenses. Flush with water, seek medical attention if irritation persists. Ingestion Not an expected route of exposure, refer to inhalation section above. Most important symptoms, effects, acute and delayed
Refer to asphyxiation acute effects as per inhalation above
Immediate medical attention and special treatment needed
If symptoms occur, seek medical advice and attention.
Section 5 โ Fire Fighting Measures Suitable extinguishing media Nitrogen is not flammable, will not burn. Use appropriate extinguishing media for surrounding fire. Special hazards arising (e.g. nature of any hazardous combustion process)
If product under pressure in closed contained, heat from fire may cause pressure to rise and container to burst. Cool any containers with water if possible. Under certain high temperature conditions, nitrogen may react violently to form nitrides with certain metals such as lithium, titanium, magnesium. Special protective equipment and precautions for firefighters
Wear appropriate protective gear and self-contained breathing apparatus. Never attempt to rescue a suspected asphyxiation victim without proper precautions, training and equipment to also avoid exposure to oxygen deficient conditions.
Section 6 โ Accidental Release Measures Personal precautions, protective equipment, emergency procedures
First responders should ensure oxygen concentration in area is safe (>19.5%) or be trained and use self-contained breathing apparatus before attempting to rescue a victim. Evacuate personnel to safe area, do not allow personnel to walk or drive in area that is potentially oxygen deficient. Use oxygen monitors to ensure adequate oxygen levels. Never enter suspected oxygen deficient area without being properly trained and wearing a self-contained breathing apparatus. Methods and materials for containment and clean up
Isolate any leaking sources of nitrogen if it can be done safely. Ventilate the area if possible.

Section 11 Toxicology Information Information on likely routes of exposure
No chemical toxicity Inhalation โ simple asphyxiant Ingestion โ not an expected route Skin โ no affects expected normally, cold gas may cause frostbite Eye โ no effects expected normally, cold gas may cause frostbite Symptoms related to physical, chemical, toxicological characteristics
As a simple asphyxiant, the presence of high concentrations causing an oxygen deficiency in air has symptoms which include dizziness, drowsiness, nausea, unconsciousness, and death. Delayed, Immediate, chronic effects from short and long term exposure

Section 13 โ Disposal Considerations Waste residues and disposal guidelines
Product will normally dissipate in air. Dispose of any contents or containers in accordance with applicable regulations. Cylinders should be returned in original shipping container/method with any valves closed and protective plugs or caps securely in place.
Section 14 โ Transport Information US DOT UN ID Number UN UN Proper Shipping Name Nitrogen, compressed DOT Transportation Hazard Class
DOT Class 2. (Non-Flammable compressed gas) Emergency Response Guide No. 121
Packing Group Not Applicable Environmental Hazards None Transport Bulk Codes Not Applicable Special Precautions Ensure vehicle driver is aware of the potential hazards of the load and knows what to do in the event of an accident or an emergency. Isolate area to avoid personnel exposure or other vehicles entering the area. High pressure gas cylinders should have outlet valves closed, with plugs/valve caps secured in place. Load space must be separated from driver compartment. Cylinders should be firmly secured from moving or falling during transport.
