  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Above 79°C explosive vapour/air mixtures may be formed.  NO open flames.  Above 79°C use a closed system and ventilation.  Use foam, powder, carbon dioxide. NO water.  In case of fire: keep drums, etc., cool by spraying with water. NO direct contact with water. 

 AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR! 
  SYMPTOMS ACUTE HAZARDS FIRST AID
Inhalation Cough. Headache. Sore throat.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. Refer for medical attention. 
Skin Dry skin. Redness. Pain.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness. Pain.  Wear 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   Do not eat, drink, or smoke during work.   

SPILLAGE DISPOSAL CLASSIFICATION & LABELLING
Personal protection: face shield and filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Ventilation. Remove all ignition sources. Do NOT wash away into sewer. Absorb liquid in sand or inert absorbent. Let solidify. 

According to UN GHS Criteria

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS LIQUID. 

Physical dangers
 

Chemical dangers
The substance rapidly polymerizes , especially under the influence of moisture. Decomposes on heating and on burning. This produces toxic and irritating fumes and gases including nitrogen oxides. 

Formula: C5H5NO2 / CH2=C(CN)COOCH3
Molecular mass: 111.1
Boiling point: 66°C
Melting point: -40°C
Relative density (water = 1): 1.1
Vapour pressure, Pa at 25°C: 24
Relative vapour density (air = 1): 3.8
Relative density of the vapour/air-mixture at 20°C (air = 1): 1
Flash point: 79°C
Octanol/water partition coefficient as log Pow: 0.03 (estimated) 


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The vapour is irritating to the eyes and respiratory tract. Inhalation of the vapour may cause asthmatic reactions. See Notes. Immediately glues (sticks to) biological tissues. 

Inhalation risk
A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C. 

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


Occupational exposure limits
TLV: 0.2 ppm as TWA.
MAK: 9.2 mg/m3, 2 ppm; peak limitation category: I(1); pregnancy risk group: D 

ENVIRONMENT
 

NOTES
Depending on the degree of exposure, periodic medical examination is suggested.
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.
Anyone who has shown symptoms of asthma due to this substance should avoid all further contact with this substance.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
