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, powder, foam, carbon dioxide. 
EXPLOSION Finely dispersed particles form explosive mixtures in air.  Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent deposition of dust.   
 
EXPOSURE      
Inhalation Cough.  Avoid inhalation of dust.  Fresh air, rest. 
Skin     Remove contaminated clothes. Rinse and then wash skin with water and soap. 
Eyes   Wear safety goggles.  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
PACKAGING & LABELLING
Sweep spilled substance into covered suitable, labelled containers. If appropriate, moisten first to prevent dusting. Personal protection: particulate filter respirator adapted to the airborne concentration of the substance.   
EC Classification
 
UN Classification
 
GHS Classification
 

EMERGENCY RESPONSE SAFE STORAGE
  Separated from incompatible materials. See Chemical Dangers. 

IMPORTANT DATA
Physical State; Appearance
WHITE SOLID IN VARIOUS FORMS. 

Physical dangers
Dust explosion possible if in powder or granular form, mixed with air. 

Chemical dangers
Decomposes on heating. This produces toxic and irritating fumes. This generates fire and explosion hazard. Reacts violently with fluorine. Reacts with strong acids and strong oxidants. 

Occupational exposure limits
TLV (NOT-ESTABLISHED):. 

Routes of exposure
 

Inhalation risk
A nuisance-causing concentration of airborne particles can be reached quickly, especially if powdered. 

Effects of short-term exposure
 

Effects of long-term or repeated exposure

NOTES
LDPE means Polyethylene with low density; HDPE means Polyethylene with high density.
Physicochemical properties vary depending upon the molecular mass.
Thermal degradation starts at 290°C.
The PE products are available in large selection of various forms, due to additives used in the manufacture.
The additives can influence the physical and toxicological properties of this substance.
