  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.        In case of fire in the surroundings, use appropriate extinguishing media.   

 PREVENT DISPERSION OF DUST! AVOID EXPOSURE OF ADOLESCENTS AND CHILDREN!  
  SYMPTOMS PREVENTION FIRST AID
Inhalation See Ingestion.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin MAY BE ABSORBED!  Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness.  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 Excessive salivation. Sweating. Diarrhoea. Dizziness. Headache. Laboured breathing. Nausea. Pupillary constriction.  Do not eat, drink, or smoke during work. Wash hands before eating.  Rinse mouth. Refer for medical attention .

PHYSICAL & CHEMICAL INFORMATION

Physical State; Appearance
COLOURLESS-TO-WHITE EXTREMELY HYGROSCOPIC CRYSTALS WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic and corrosive fumes including nitrogen oxides and hydrogen chloride. Decomposes on heating with strong aqueous alkali solutions. This produces trimethylamine and other gaseous products. Attacks many metals in the presence of water. 

Formula: (ClCH2CH2N(CH3)3)Cl / C5H13Cl2N
Molecular mass: 158.1
Decomposes at 245°C
Solubility in water, g/100ml at 20°C: 74 (good)
Vapour pressure at 20°C: negligible 


EXPOSURE & HEALTH EFFECTS

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

Effects of short-term exposure
The aerosol is mildly irritating to the eyes. The substance may cause effects on the nervous system, cholinergic symptoms without acetylcholinesterase inhibition. See Notes. 

Inhalation risk
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed. 

Effects of long-term or repeated exposure
 


OCCUPATIONAL EXPOSURE LIMITS
 

ENVIRONMENT
The substance is harmful to aquatic organisms. Avoid release to the environment in circumstances different to normal use. 

NOTES
Use of atropine as specific treatment is contraindicated.
If the substance is formulated with solvents also consult the ICSCs of these materials.
Carrier solvents used in commercial formulations may change physical and toxicological properties.
