TYPES OF
HAZARD /
EXPOSURE
ACUTE HAZARDS / SYMPTOMS      PREVENTION      FIRST AID / FIRE FIGHTING
FIRE Combustible.  NO open flames.  Use powder, alcohol-resistant foam, water in large amounts, carbon dioxide. 
EXPLOSION Finely dispersed particles form explosive mixtures in air.  Prevent deposition of dust.   
 
EXPOSURE   PREVENT DISPERSION OF DUST!   
Inhalation Cough.  Use ventilation, local exhaust or breathing protection.  Fresh air, rest. 
Skin   Protective gloves.  Remove contaminated clothes. 
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. 

SPILLAGE DISPOSAL
PACKAGING & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting. Wash away remainder with plenty of water.

IMPORTANT DATA
Physical State; Appearance
WHITE POWDER WITH CHARACTERISTIC ODOUR. 

Physical dangers
Dust explosion possible if in powder or granular form, mixed with air. If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc. 

Chemical dangers
Reacts violently with oxidants. This generates fire and explosion hazard. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

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

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

Effects of short-term exposure
May cause mechanical irritation. 

Effects of long-term or repeated exposure
Repeated or prolonged inhalation may cause effects on the lungs. 


PHYSICAL PROPERTIES ENVIRONMENTAL DATA
See Notes.
Density: 1.1 - 1.4 g/cm³
Solubility in water: good 
 

NOTES
The substance is combustible but no flash point is available in literature.
properties may vary with the molecular weight. Physical properties are for the acid form of the polymer.
The recommendations on this Card also apply to [polyacrylic acid, CAS# 9003-01-4].
