4.First-aid measures

4.1 Description of necessary first-aid measures

General advice

Consult a physician. Show this safety data sheet to the doctor in attendance.

If inhaled

Fresh air, rest.

In case of skin contact

Wash off with soap and plenty of water. Consult a physician.

In case of eye contact

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

If swallowed

Never give anything by mouth to an unconscious person. Rinse mouth with water. Consult a physician.

4.2 Most important symptoms/effects, acute and delayed

Can cause death or permanent injury after a very short exposure to small quantities. Irritant of eyes, nose, throat; can cause unconsciousness. Nitric oxide forms acids in the respiratory system which are irritating and cause congestion in the lungs. Concentrations of 60-150 ppm cause immediate irritation of the nose and throat with coughing and burning in the throat and chest. 6-24 hours after exposure, labored breathing and unconsciousness may result. Concentrations of 100-150 ppm are dangerous for short exposure of 30-60 minutes. Concentrations of 200-700 ppm may be fatal after very short exposure. (EPA, 1998)

4.3 Indication of immediate medical attention and special treatment needed, if necessary

Basic treatment: Establish a patent airway. Suction if necessary. Aggressive airway management may be needed. Encourage patient to take deep breaths. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for pulmonary edema and treat if necessary ... . Monitor for shock and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuosly with normal saline during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. ... /Nitrogen oxides (NOX) and related compounds/

5.Fire-fighting measures

5.1 Extinguishing media

Suitable extinguishing media

Wear positive pressure breathing apparatus and full protective clothing. Move container from fire area if you can do so without risk. Stay away from ends of tanks. Spray cooling water on containers that are exposed to flames until well after fire is out. For massive fire in cargo area, use unmanned hose holder or monitor nozzles; if this is impossible, withdraw from area and let fire burn. For small fires, use dry chemical or carbon dioxide. For large fires, use water spray, fog, or foam. (EPA, 1998)

5.2 Specific hazards arising from the chemical

Burns only when heated with hydrogen. With carbon disulfide, it reacts explosively with emission of light. When mixed with chlorine monoxide, can be explosive. Explodes on contact with nitrogen trichloride. When mixed with ozone, it will explode. Will react with water or steam to produce heat and corrosive fumes. Reacts vigorously with reducing materials. When heated to decomposition, highly toxic fumes of nitrogen oxides are emitted. May ignite other combustible materials (wood, paper, oil, etc.). Mixture with fuels may explode. Container may explode in heat of fire. Vapor explosion and poison hazard indoors, outdoors or in sewers. Reacts with oxygen to form poisonous nitrogen dioxide. Avoid storing in direct sunlight, or areas of high fire hazard. Incompatible with aluminum, boron, carbon disulfide, hypochlorite, chromium, fluorine, fuels, hydrocarbons, nitrogen trichloride, ozone, phosphorus, uns-dimethyl hydrazine, uranium, acetic anhydride, ammonia, barium oxide, boron trichloride, methyl chloride, 1,2-dichloroethane, dichloroethylene, ethylene, iron, magnesium, manganese, olefins, potassium, propylene, sodium, sulfur, trichloroethylene, 1,1,1-trichloroethane, uns-tetrachloroethaneand reducing agents. (EPA, 1998)

5.3 Special protective actions for fire-fighters

Wear self-contained breathing apparatus for firefighting if necessary.

6.Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures

Use personal protective equipment. Avoid dust formation. Avoid breathing vapours, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas. Avoid breathing dust. For personal protection see section 8.

6.2 Environmental precautions

Personal protection: gas-tight chemical protection suit including self-contained breathing apparatus. Shut off cylinder if possible. Isolate the area until the gas has dispersed.

6.3 Methods and materials for containment and cleaning up

1) VENTILATE AREA OF LEAK OR RELEASE TO DISPERSE GAS. 2) STOP FLOW OF GAS. IF SOURCE ... IS CYLINDER & LEAK CANNOT BE STOPPED IN PLACE, REMOVE ... CYLINDER TO SAFE PLACE IN OPEN AIR, & REPAIR LEAK OR ALLOW ... TO EMPTY.

7.Handling and storage

7.1 Precautions for safe handling
