1 DOT ID No: UN 1956 MATERIAL SAFETY DATA SHEET DOT Hazard Class: 2.2 DOT Shipping Label : Non-Flammable Gas Emergency No.: Page No. : 1/5 Date last updated: 03/10/2009 Chemical Product Nitric Oxide in Nitrogen Synonyms: None 1. Composition/Information on Ingredients Ingredient Formula CAS Number Concentration OSHA PEL ACGIH TLV Nitric Oxide NO % Nitrogen N Balance SA SA NE: None Established S/A: Simple Asphyxiant 2. Hazards Identification ***EMERGENCY OVERVIEW*** High Pressure gas. Can cause rapid suffocation. Can cause lung damage. Can cause eye and skin burns. Symptoms may be delayed. Potential Acute Health Effects: Routes of Entry Acute Effects Chronic Effects Medical Conditions Aggravated by Overexposure Inhalation, Skin. Mixture can act as a simple Asphyxiant by displacing air necessary or life. Nitric oxide form acids in the lungs which are irritants that cause congestion of the throat and bronchi and edema of the lungs. Symptoms include headache, lowering of blood pressure, dizziness, development of cyanosis and loss of consciousness. Because of its minor irritating affects on the upper respiratory tract, the warning properties are limited. Nitric may cause permanent decrements in pulmonary function. None known Carcinogenicity (US Only) NTP - No IARC Monographs No OSHA Regulated - No

2 Page No.: 2/5 3. First Aid Measures Eyes Inhalation Skin Contact Ingestion In Event of Exposure, Consult a Physician Note to Physician Immediately flush with copious amounts of water for at least 15 minutes. Immediately remove victim to fresh air. If breathing has stopped, give artificial respiration. If breathing is difficult, give oxygen. Lay victim with head and chest lower than hips to improve drainage of fluids from the lungs. Immediately flush with copious amounts of water for at least 15 minutes while removing contaminated clothing. None. Signs and symptoms of pulmonary edema can delayed for several hours. 4. Fire Fighting Measures Product Flammability Hazards Combustion Products Extinguishing Media Special Fire fighting instruction and Equipment Unusual Fire and Explosion Hazards Autoignition Temperature Non- flammable Nitric oxide in contact with air forms highly toxic fumes of NOx. Use what is appropriate for surrounding fire Wear self-contained breathing apparatus and full protective clothing. Keep fire exposed cool with water spray. If possible stop the product flow. Cylinder rupture may occur under fire. 5. Accidental Release Measures Clean Up Procedure Specialized Equipment Evacuate and ventilate area. Remove leaking cylinder to exhaust hood or safe outdoor area. Remove source of ignition and combustibles To dispose of gas into an adequate amount of alkaline potassium permanganate solution. Leaks of Nitric oxide detectable by the formation of reddish-brown NO 2.

Use suitable hand truck to move cylinders. Store in well ventilated areas away from combustibles. Keep valve protection cap on cylinders when not in use. 7. Exposure Controls/Personal Protection Engineering Controls Provide adequate general and local exhaust ventilation to maintain concentration below the exposure limits. Eye/Face Protection Use safety goggles or glasses. Skin Protection None. Respiratory Protection In Case of leakage, use self-contained breathing apparatus. Protective Equipment Safety Shoes when handling cylinders. 8. Physical and Chemical Properties Appearance Odor Physical Pressure Vapor Pressure Vapor Density (air=1) Boiling Point (c) Solubility in Water Specific Gravity (H 2 O=1) Evaporation Rate Odor Threshold Colorless.

4 Page No.: 4/5 Hazardous Polymerization Hazardous Decomposition Will not occur. In contact with air Nitric oxide forms toxic fumes of NOx. 10. Toxicological Information Lethal Concentration (LC50) Lethal Dose 50 (LD50) Teratogenicity Reproductive Effects Mutagenicity 115 ppm, Rat 1 hour. 11. Ecological Information No adverse ecological effects are expected. 12. Disposal Considerations Waste Disposal Method Return cylinders to supplier with any valve outlet plugs or caps secured and valve protection caps in place. Dispose of nonrefillable cylinders in accordance with federal, state, and local regulation. 13. Transport Information DOT Description PROPER SHIPPING NAME : Compressed Gas, N.O.S.
