| Section 3 : Hazards Identification |
| |
| Emergency
Overview: |
Danger! Toxic if swallowed or dust is inhaled. Causes irritation to skin, eyes and respiratory tract. Oxidizer: May ignite organic materials and react with other materials. Can decompose if mixed with acids or exposed to fire conditions, releasing toxic nitrogen oxides.
|
| Potential Health Effects |
| Routes
of Entry: |
Inhalation, Ingestion, Eye Contact and Skin Contact
|
| Target
Organs: |
Eyes, Skin, Respiratory System and Kidneys
|
| Skin
Contact: |
Skin contact may cause irritation with symptoms of redness, swelling, itching and pain.
|
| Eye
Contact: |
Eye contact may cause irritation with symptoms of redness,
itching, tearing and pain.
|
| Inhalation: |
Inhalation of Sodium Nitrite produces irritation of respiratory tract,
irregular breathing, sore throat, cough and vomiting.
Symptoms might be similar to those of ingestion. |
| Ingestion: |
Sodium Nitrite is toxic. As little as 1 gms may be
fatal. Ingestion may cause Gastroenteritis, nausea,
dizziness, vomiting, rapid heart beat, irregular
breathing, coma, convulsions, and death due to circulatory
collapse. |
| Chronic
Exposure: |
May
lead to symptoms of acute toxicity |
| Explanation
of Carcinogenicity: |
Not listed by NTP or IARC or OSHA |
| Medical
conditions aggravated by exposure: |
Persons with preexisting eyes or skin conditions or impaired pulmonary function may be more susceptible to the effects of this product.
|
|
| |
| Section 4: First Aid Measures |
|
|
| Eyes: |
Incase of contact, immediately flush eyes with plenty of water for atleast 15 minutes. Get medical aid immediately. |
| Skin: |
Incase of contact, immediately flush skin with plenty of water for atleast 15 minutes while removing contaminated clothing and shoes. Get medical aid immediately. Wash clothing before reuse. |
| Ingestion: |
Call physician immediately. |
| Inhalation: |
If inhaled, remove to fresh air. If not breathing give artificial respiration. If breathing is difficult give Oxygen. Get medical aid immediately. |
|
Notes to Physicians: |
Absorption of Sodium nitrite into the body leads to the
formation of methemoglobin which, in sufficient
concentration, causes cyanosis. Since reversion of
methemoglobin to hemoglobin occurs spontaneously after
termination of exposure, moderate degrees of cyanosis need
to be treated only by supportive measures such as bed rest
and oxygen inhalation. Thorough cleansing of the entire
contaminated area of the body including scalp and nails is
of utmost importance. Cyanocobalamin (Vitamin B-12), 1 mg
intramuscularly, will speed recovery. Intravenous fluids
and blood transfusions may be indicated in very severe
exposures. |

| Unusual Fire and Explosion Hazards |
Sodium Nitrite is not combustible but being a strong oxidizer, its contact with oxidizing agents may cause a violent explosion. It may explode on contact with cyanides, ammonium salts, cellulose, lithium, potassium plus ammonia, and sodium thiosulfate. Sodium Nitrite also explodes on heating above 538°C (1000 °F). |
| Extinguishing Media |
Use water
spray or foam. Avoid use of of multi-purpose dry chemical
fire extinguishers. |
| NFPA Rating |
Health:

| General Information |
Fire fighters should wear a full protective gear, with a
self-contained breathing apparatus with full face piece
operated in positive pressure mode.
|
|
| |
| Section 6: Accidental Release Measures |
|
|
|
General Information: Remove all sources of ignition. Ventilate area of leak or spill. Utilize recommended protective clothing and equipment as specified in section 8.
Spills: Clean the spill in a manner that does not disperse dust into the air. Use non-sparking tool and equipment. Spill area can be washed with water. Collect wash water for approved disposal. Water disposal should be in accordance with existing federal, state and local environmental regulations.
|
| |
| Section 7: Handling and Storage |
| |
| Handling: |
Wash thoroughly after handling. Do not ingest or inhale. Do not get in eyes, on skin or on clothing.
|
| Storage: |
Store in a dry, well-ventilated and cool area away from incompatible substances
(refer section 10). Keep container tightly closed.
|
|
| |
| Section 8: Exposure Controls /Personal Protection |
|
|
Engineering Controls:
Facilities storing or utilizing the material should be equipped with an eyewash facility and a safety shower. Use adequate general or local exhaust ventilation to
prevent contact with vapors or dust from dried down product.
