TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  NO open flames.  Use water spray, dry powder, carbon dioxide, foam. 
EXPLOSION      
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Cough.  Use local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves. Protective clothing.  Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention . 
Eyes Redness.  Wear safety spectacles.  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.  Rinse mouth. Refer for medical attention . 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered plastic containers. If appropriate, moisten first to prevent dusting. Do NOT let this chemical enter the environment.

IMPORTANT DATA
Physical State; Appearance
COLOURLESS-TO-WHITE CRYSTALS WITH CHARACTERISTIC ODOUR. 

Physical dangers
 

Chemical dangers
Decomposes on heating. This produces toxic fumes including chlorine and nitrogen oxides. Reacts with aluminium and magnesium. 

Occupational exposure limits
TLV: 10 mg/m³ as TWA; 20 mg/m³ as STEL; A4 (not classifiable as a human carcinogen); (ACGIH 2008). 

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

Inhalation risk
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C. 

Effects of short-term exposure
See Notes. 

Effects of long-term or repeated exposure
 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
Boiling point at 1.5kPa: 136°C
Melting point: 63°C
Solubility in water: none
Vapour pressure, Pa at 23°C:
Relative density of the vapour/air-mixture at 20°C (air = 1): 1.0
Flash point: 100°C c.c.
Octanol/water partition coefficient as log Pow: 3.4  
The substance is toxic to aquatic organisms. This substance does enter the environment under normal use. Great care, however, should be taken to avoid any additional release, for example through inappropriate disposal. 

NOTES
Insufficient data are available on the effect of this substance on human health, therefore utmost care must be taken.
N-Serve, Dowco-163 are trade names.
Card has been partially updated in February 2009: see Occupational Exposure Limits.
