| TYPES OF HAZARD / EXPOSURE | ACUTE HAZARDS / SYMPTOMS | PREVENTION | FIRST AID / FIRE FIGHTING |
| FIRE |
Flammable.
|
NO open flames, NO sparks, and NO smoking.
|
Alcohol-resistant foam, foam. water spray, dry powder, carbon dioxide.
|
| EXPLOSION |
Above 40°C explosive vapour/air mixtures may be formed. Risk of fire and explosion on contact with many materials.
|
Above 40°C use a closed system, ventilation, and explosion-proof electrical equipment.
|
In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.
|
| EXPOSURE |
|
AVOID ALL CONTACT!
|
IN ALL CASES CONSULT A DOCTOR!
|
| Inhalation |
Cough. Burning sensation. Headache. Confusion. Drowsiness. Nausea. Shortness of breath. Convulsions. Unconsciousness.
|
Closed system and ventilation.
|
Fresh air, rest. Half-upright position. Refer immediately for medical attention.
|
| Skin |
MAY BE ABSORBED! Redness. Pain. Skin burns.
|
Protective gloves. Protective clothing.
|
First rinse with plenty of water, then remove contaminated clothes and rinse again. (See Notes). Refer immediately for medical attention.
|
| Eyes |
Redness. Pain. Blurred vision. Severe burns.
|
Face shield and eye protection in combination with breathing protection.
|
Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.
|
| Ingestion |
Burns in mouth and throat. Abdominal pain. Diarrhoea. Vomiting. Shock or collapse. Further (see Inhalation).
|
Do not eat, drink, or smoke during work. Wash hands before eating.
|
Rinse mouth. Give nothing to drink. Do NOT induce vomiting. Refer immediately for medical attention.

| IMPORTANT DATA | |||
|
PHYSICAL STATE; APPEARANCE: COLOURLESS, FUMING, OILY AND HYGROSCOPIC LIQUID , WITH PUNGENT ODOUR. CHEMICAL DANGERS: The substance decomposes producing ammonia, hydrogen and nitrogen oxides , causing fire and explosion hazard. The substance is a strong reducing agent and reacts violently with oxidants. The substance is a medium strong base. Reacts violently with acids, many metals, metal oxides and porous materials causing fire and explosion hazard. Air or oxygen is not required for decomposition. OCCUPATIONAL EXPOSURE LIMITS: TLV: 0.01 ppm as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); (ACGIH 2009). MAK: skin absorption (H); sensitization of skin (Sh); Carcinogen category: 2; (DFG 2009). |
ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation, through the skin and by ingestion. Serious local effects by all routes of exposure. INHALATION RISK: A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance is corrosive to the eyes, the skin and the respiratory tract. Inhalation may cause lung oedema, but only after initial corrosive effects on eyes and/or airways have become manifest. Corrosive on ingestion. The substance may cause effects on the liver and central nervous system. Exposure may result in death. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. The substance may have effects on the liver, kidneys, and central nervous system. This substance is possibly carcinogenic to humans. | ||

Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00 Flash point: 40°C c.c. Auto-ignition temperature: 270°C Explosive limits, vol% in air: 4.7-100 Octanol/water partition coefficient as log Pow: -2.1 Viscosity, mm²/s at 20°C: 0.0009 | ||
| ENVIRONMENTAL DATA | |||
|
The substance is very toxic to aquatic organisms. It is strongly advised that this substance does not enter the environment.
| |||
| NOTES | |||
|
Auto-ignition temperature varies from 24°C on a rusty iron surface to 270°C on glass surface. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. The odour warning when the exposure limit value is exceeded is insufficient. Rinse contaminated clothes with plenty of water because of fire hazard. Do NOT take working clothes home. Other UN numbers are: UN 2030 Hydrazine aqueous solution, with more than 37% hydrazine by mass, having a flash-point of not more than 60 °C: hazard class: 8, subsdiary risks: 3 and/or 6.1, packing group: I; Hydrazine aqueous solution, with more than 37% hydrazine by mass: hazard class: 8, subsdiary risk: 6.1, packing group: II-III. UN 3293 Hydrazine, aqueous solutions with not more than 37% of hydrazine, hazard class: 6.1, packing group: III. Other CAS-numbers are: 7803-57-8 for the 64% aqueous solution and 10217-52-4 for the 55% aqueous solution.
