EXPOSURE   AVOID ALL CONTACT!  IN ALL CASES CONSULT A DOCTOR! 
Inhalation Cough. Sore throat. Burning sensation behind the breastbone. Headache. Shortness of breath.  Use local exhaust or breathing protection.  Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer immediately for medical attention. 
Skin Redness. Pain. Skin burns.  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Watering of the eyes. Redness. Pain. Severe burns.  Wear face shield or 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. Nausea. Abdominal pain. Shock or collapse.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Do NOT induce vomiting. Refer immediately for medical attention.

Physical dangers
 

Chemical dangers
The substance may polymerize if it is not stabilized. Reacts with acids and strong oxidants. 

Occupational exposure limits
TLV: 0.3ppm (ceiling value); (SEN); A2 (suspected human carcinogen); (ACGIH 2011).
MAK: 0.3 ppm, 0.37 mg/m³; Carcinogen category: 4; Peak limitation category: I(2); Pregnancy risk group: C; Germ cell mutagen group: 5; Sensitization of skin (SH); (DFG 2011).
EU OEL ( selected): SCOEL recommendation available. 

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

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

Effects of short-term exposure
The substance is severely irritating to the eyes and skin. The vapour is severely irritating to the respiratory tract. Inhalation of high concentrations may cause lung oedema, but only after initial corrosive effects on the eyes and the upper respiratory tract have become manifest. 

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. Repeated or prolonged contact may cause skin sensitization. Repeated or chronic inhalation of the vapour may cause chronic inflammation of the upper respiratory tract. This substance is carcinogenic to humans. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point: 98°C
Solubility in water: miscible
Relative density (water = 1): 0.8
Flash point: 83°C c.c.
Vapour pressure, kPa at 20°C: 0.2
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00
Relative vapour density (air = 1): 1.03  
The substance is harmful to aquatic organisms. 

NOTES
Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered.
EU SCOEL recommendation: 0.2 ppm (8h); 0.4 ppm STEL; Skin sensitation, 2008. (Genotoxic carcinogen for which a practical treshold is supported.)
Methanol, added as stabilizer or inhibitor to commercial formulations, can influence the physical and toxicological properties of this substance.
