TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Flammable. Gives off irritating or toxic fumes (or gases) in a fire.  NO contact with hot surfaces. NO contact with oxidizing agents.  Use dry powder, carbon dioxide, alcohol-resistant foam. NO water. 
EXPLOSION Above 51°C explosive vapour/air mixtures may be formed.  Above 51°C use a closed system, ventilation and explosion-proof electrical equipment.  In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. 
 
EXPOSURE   AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Cough. Sore throat. Burning sensation. Laboured breathing. Shortness of breath. Symptoms may be delayed. See Notes.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention. 
Skin Redness. Blisters. Pain. Skin burns.  Protective clothing. Protective gloves.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Watering of the eyes. Redness. Pain. Severe deep burns.  Wear safety goggles or face shield.  First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention. 
Ingestion Burning sensation. Abdominal pain. Shock or collapse.  Do not eat, drink, or smoke during work.  Rinse mouth. Give one or two glasses of water to drink. Do NOT induce vomiting. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: chemical protection suit including self-contained breathing apparatus. Ventilation. 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.  Do not transport with food and feedstuffs.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-YELLOW LIQUID WITH PUNGENT ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces hydrogen cyanide and nitrogen oxides. Reacts violently with water. Reacts with strong oxidants, strong acids, strong bases, alcohols and amines. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):.
MAK: Sensitization of respiratory tract and skin (SAH); (DFG 2004). 

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

Inhalation risk
A harmful concentration of airborne particles can be reached quickly when dispersed. 

Effects of short-term exposure
Lachrymation. The substance is corrosive to the eyes, skin and respiratory tract. 

Effects of long-term or repeated exposure
Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 158-168°C
Melting point: -30°C
Relative density (water = 1): 1.095
Solubility in water: reaction
Vapour pressure, kPa at 20°C: 0.2
Flash point: 51°C c.c.
Auto-ignition temperature: 300°C  
 

NOTES
Anyone who has shown symptoms of asthma due to this substance should avoid all further contact.
The symptoms of asthma 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.
Do NOT take working clothes home.
Card has been partly updated in April 2005.
