Usage
An intermediate for chemical synthesis and, for example, for the production of azodicarbonamide, a blowing agent for the foaming of plastics. Foam plastics are processed in many consumer goods as for shoes, furniture and cars corrosion protection in closed water circuits. As an antioxidant, it protects pipes from rust and premature aging, particularly in the steam circuits of the power industry, manufacture medicines, including those for the treatment of tb, forms of depression and hypertension. And for crop protection products, hydrazine is a vital intermediate for growth regulators, for instance.

Ingestion
Do NOT induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately.

Inhalation
Remove from exposure to fresh air immediately. If breathing is difficult, give oxygen. Get medical aid. DO NOT use mouth-to-mouth respiration. If breathing has ceased apply artificial respiration using oxygen and a suitable mechanical device such as a bag and a mask.

Skin
Get medical aid immediately. Immediately flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before reuse. Discard contaminated clothing in a manner which limits further exposure.

Eyes
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately. Do NOT allow victim to rub or keep eyes closed.

Storage
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Do not store in direct sunlight. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Corrosives area.

Handling
Keep away from heat, sparks, and flame. Keep away from sources of ignition. Do not store in direct sunlight. Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. Storage under a nitrogen blanket has been recommended.

Inhalation
Effects may be delayed. Irritation may lead to chemical pneumonitis and pulmonary edema. May cause liver and kidney damage. May cause severe irritation of the respiratory tract with possible burns.

Skin
Causes skin burns. May cause skin sensitization, an allergic reaction, which becomes evident upon re-exposure to this material. May be absorbed through the skin.

Eyes
Causes eye burns. Effects may be delayed.

Ingestion
Harmful if swallowed. May cause severe gastrointestinal tract irritation with nausea, vomiting and possible burns. May cause liver and kidney damage. Exposure may cause anemia and other blood abnormalities.

Hazards
When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards.

Personal Protection
Wear appropriate protective gloves, clothing and goggles.

Respirators
Wear positive pressure self-contained breathing apparatus (SCBA).

Exposure Effects
Prolonged or repeated exposure may cause adverse reproductive effects. Repeated inhalation may cause chronic bronchitis. May cause fetal effects. May cause cancer according to animal studies. Repeated exposure may cause sensitization dermatitis. Chronic exposure may lead to liver and lung damage.

Fire Potential
Combustible material: may burn but does not ignite readily.

Small spills/leaks
ELIMINATE all ignition sources. Do not touch damaged containers or spilled material unless wearing appropriate protective clothing. Stop leak if you can do it without risk. Absorb or cover with dry earth, sand or other non-combustible material and transfer to containers. DO NOT GET WATER INSIDE CONTAINERS.

Stability
Stable. However becomes unstable if dehydrated.

Incompatibilities
Substance is incompatible with oxidizers, combustible materials, alkali metals, chloride, fluorine, and ammonia. Hydrazine is highly reactive reducing agent. May ignite spontaneously in contact with oxidizers. Incompatible with oxidizing agents (incl. air), acids, and some metal oxides and metals. Substance may spontaneously ignite in air when in contact with porous materials. Ignites on contact with dinitrogen oxide and tetroxide, hydrogen peroxide, tetryl, and nitric acid. Explodes on contact with dicyanofurazan, n-halomides, potassium, silver compounds, sodium hydroxide, titanium compounds, and trioxygen difluoride. Explosive compounds may result from contact with air, chloromethylnitrobenzene, lithium perchlorate, metal salts, methanol + nitromethane, sodium, and sodium perchlorate.

Decomposition
Nitrogen oxides, carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, ammonia and/or derivatives.

Combustion Products
Fire may produce irritating, corrosive and/or toxic gases.
