TYPES OF
HAZARD /
EXPOSURE 		ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Highly flammable.  NO open flames, NO sparks and NO smoking.  Use water in large amounts, powder, alcohol-resistant foam, carbon dioxide. 
EXPLOSION Vapour/air mixtures are explosive.  Closed system, ventilation, explosion-proof electrical equipment and lighting.  In case of fire: keep drums, etc., cool by spraying with water. 
 
EXPOSURE   STRICT HYGIENE!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Cough. Laboured breathing. Sore throat. Shortness of breath.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Artificial respiration may be needed. Refer for medical attention. 
Skin Redness. Skin burns. Pain. Blisters.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention . 
Eyes Redness. Pain. Blurred vision. Severe deep burns.  Wear safety spectacles, face shield or eye protection in combination with breathing protection.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Diarrhoea. Sore throat. Vomiting. Abdominal pain. Burning sensation. Shock or collapse.  Do not eat, drink, or smoke during work.  Rinse mouth. Do NOT induce vomiting. Refer for medical attention . See Notes. 

SPILLAGE DISPOSAL
 		PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. Remove all ignition sources. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS LIQUID WITH CHARACTERISTIC ODOUR. 

Physical dangers
The vapour is heavier than air and may travel along the ground; distant ignition possible. 

Chemical dangers
Decomposes on burning. This produces toxic fumes and gases (ammonia, nitrogen oxides). The substance is a weak base. Reacts with strong oxidants and strong acids. Attacks tin, aluminium and some steels. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK: 5 ppm, 15 mg/m³; Peak limitation category: I(2); Skin absorption (H); (DFG 2004). 

Routes of exposure
The substance can be absorbed into the body by inhalation of its vapour and by ingestion. 

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, skin and respiratory tract. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis.
