  ACUTE HAZARDS PREVENTION FIRE FIGHTING
FIRE & EXPLOSION Combustible. Gives off irritating or toxic fumes (or gases) in a fire.  Finely dispersed particles form explosive mixtures in air.  NO open flames.  Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.  Use water spray, powder, foam, carbon dioxide.   

   
  SYMPTOMS PREVENTION FIRST AID
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 CLASSIFICATION & 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. 

According to UN GHS Criteria

PACKAGING
 
POLYETHYLENE ICSC: 1488
PHYSICAL & CHEMICAL INFORMATION

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.

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.
