Ingredients - Composition Information
Component:Nitrogen
CAS No.7727-37-9
Percent (by weight)99.0% 100.0%
ACGIH - STELSimple Asphyxiant
Emergency Overview
Danger:High pressure gas. Can cause rapid suffocation. Do not breathe gas. Self contained breathing apparatus may be required by rescue workers.
Potential Health Effects Information
Inhalation:Simple asphyxiant. Nitrogen is nontoxic, but may cause suffocation by displacing the oxygen in air. Exposure to oxygen-deficient atmosphere (<19.5%) may cause dizziness, drowsiness, nausea, vomiting, excess salivation, diminished mental alertness, loss of consciousness and death. Exposure to atmospheres containing 8-10% or less oxygen will bring about unconsciousness without warning and so quickly that the individuals cannot help or protect themselves. Lack of sufficient oxygen may cause serious injury or death.
Eye:None.
Skin:None.
Ingestion:None.
Medical Conditions Aggravated By OverexposureNone.
Carcinogenicity:Not listed in NTP, OSHA or IARC
First Aid Measures
Inhalation:Persons suffering from lack of oxygen should be removed to fresh air. If victim is not breathing, administer artificial respiration. If breathing is difficult, administer oxygen. Obtain prompt medical attention.
Eye:None.
Skin:None.
Ingestion:None.
Notes To Physician:None.
Fire Fighting Measures
Flash Point:Not applicable; Gas.
Auto ignition:None
Flammable Limits - Lower: None
Flammable Limits - Upper:None
Extinguishing Media:Nitrogen is nonflammable and does not support combustion. Use extinguishing media appropriate for the surrounding fire.
Fire Fighting Instructions:Nitrogen is a simple asphyxiant. If possible, remove nitrogen cylinders from fire area or cool with water. Do not direct water spray at the container vent. Self-contained breathing apparatus may be required for rescue workers. Evacuate this area.
Hazardous Combustion Products:Not known
Sensitivity To Static Discharge: None
Sensitivity To Mechanical Impact:None
Accidental Release Measures
Evacuate:Evacuate all personnel from the affected area. Shut off source of Nitrogen if possible without risk. Ventilate area or remove leaking containers to a well ventilated location. If leaking from cylinder or its valve, contact your supplier.
Handling and Storage
Storage:Store and use with adequate ventilation. Cylinders should be stored upright with valve protection cap in place and firmly secured to prevent falling or being knocked over. Protect cylinders from physical damage; do not drag, roll, slide or drop. Do not allow storage area temperature to exceed 125°F (52°C). Full and empty cylinders should be segregated. Use a first-in, first-out inventory system to prevent full containers from being stored for long periods of time
Handling:Use a suitable hand truck for cylinder movement. Never attempt to lift a cylinder by its valve protection cap. Keep cylinders and their valves free from oil and grease. Open valve slowly. If user experiences difficulty operating cylinder valve, discontinue use and contact supplier. Never insert an object (e.g., wrench,screwdriver, pry bar, etc.) into valve cap openings. Doing so may damage valve, causing a leak to occur. Never strike an arc on a compressed gas cylinder or make a cylinder a part of an electrical circuit. Use an adjustable strap wrench to remove over-tight or rusted caps. For additional precautions in using nitrogen see Section 16
Exposure Control - Personal Protection
Engineering Controls:
Ventilation:Natural or mechanical to prevent oxygen-deficient atmospheres under 19.5% oxygen.
Personal Protective Equipment (PPE):
Skin Protection:
Clothing:Cotton clothing is recommended for use to prevent static buildup.
Glasses: Safety glasses are recommended when handling cylinders.
Shoes:Safety shoes are recommended when handling cylinders.
Gloves:Work gloves are recommended when handling cylinders.
