Overview
Sodium nitrite (NaNO2) forms a protective oxide film that passivates steel surfaces.
Applications
Clean the Metal Surface completely either by using Solvent Cleaner / Detergent / Acidic Powder like Sulfamic - CITRIC / Surfactant. After cleaning Passivate with Sodium Nitrite Standard Solution.
Characteristics and notes
Carbohydrazide also passivates metals and reduces metal oxides converting ferric oxide to ferrous oxide and converting cupric oxide to cuprous oxide.
Carbohydrazide reacts directly with oxygen. It helps prevent oxygen damage and continues to passivate metal surfaces during wet lay-up. Carbohydrazide can also be used as a curing agent for epoxide-type resins.
Safety and SDS
Read the safety data sheet before handling. Wear suitable gloves and eye protection.

| General Advice | Show this material safety data sheet to the doctor in attendance. |
| Swallowed | IF SWALLOWED: Rinse mouth. Do not induce vomiting. Call a Poison Centre or doctor/physician for advice. Never give anything by mouth to an unconscious person. |
| Eye | IF IN EYES: Immediately flush eyes with running water for several minutes, holding eyelids open and occasionally lifting the upper and lower lids. Remove contact lenses if present and easy to do. Continue rinsing for at least 15 minutes. If eye irritation persists, get medical advice/attention. |
| Skin | IF ON SKIN: Remove and isolate contaminated clothing and shoes. Immediately flush skin with running water for at least 15 minutes. If skin irritation occurs, get medical advice/attention. Wash contaminated clothing and shoes before reuse. *Contaminated clothing may be a fire risk when dry. |
| Inhaled | IF INHALED: Remove victim to fresh air and keep at rest in a position comfortable for breathing. If respiratory symptoms persist, get medical advice/attention. Give artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; give artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult. |
| Advice to Doctor | Treat symptomatically. Keep victim calm and warm. Ensure that attending medical personnel are aware of identity and nature of the product(s) involved, and take precautions to protect themselves. *Most important symptoms and effects, both acute and delayed: Absorption of nitrates by ingestion, inhalation or through burnt or broken skin may cause dilation of the blood vessels by direct smooth muscle relaxation with a subsequent lowering of blood pressure and may also cause breathing difficulties, blueness of the skin (cyanosis) and methaemoglobinaemia. Following inhalation of oxides of nitrogen the patient should be observed in hospital for 24 hours for delayed onset of pulmonary oedema |
| Indication of any immediate medical attention and special treatment needed | No data available |
| General Measures | Move containers from fire area if you can do it without risk. Do not move cargo or vehicle if cargo has been exposed to heat. Cool containers with flooding quantities of water until well after fire is out. ALWAYS stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn. |
| Flammability Conditions | OXIDISING SUBSTANCE: Will accelerate burning when involved in a fire. |
| Extinguishing Media |
If material is involved in a fire, use water for extinction. Do not use dry chemicals or foams. CO2 or Halon® may provide limited control. *Large fire: Flood fire area with water from a distance
|
| Fire and Explosion Hazard | Risk of violent reaction or explosion! May explode from heat or contamination. May ignite combustibles. Containers may explode when heated. Runoff may create fire or explosion hazard |
| Hazardous Products of Combustion | Fire or heat may produce irritating and/or toxic gases, including oxides of nitrogen. . |
| Special Fire Fighting Instructions | Contain runoff from fire control or dilution water - Runoff may cause pollution. |
| Personal Protective Equipment | Wear positive pressure self-contained breathing apparatus (SCBA). Wear chemical protective clothing - It may provide little or no thermal protection. Structural firefighters’ protective clothing will only provide limited protection. |
| Personal precautions, protective equipment and emergency procedures |
Advice for non-emergency personnel: Do not breathe vapors, aerosols. Avoid substance contact. Ensure adequate ventilation. Evacuate the danger area, observe emergency procedures, consult an expert.
