`
`
`FIRE &
`EXPLOSION
`
`ACUTE HAZARDS
`Combustible. Gives off irritating or toxic
`fumes (or gases) in a fire. Finely
`dispersed particles form explosive
`mixtures in air.
`
`PREVENTION
`
`FIRE FIGHTING
`
`NO open flames. Closed system, dust
`explosion-proof electrical equipment and
`lighting. Prevent deposition of dust.
`
`Use water spray, powder, foam, carbon
`dioxide.
`
`
`Inhalation
`
`Cough.
`
`SYMPTOMS
`
`Skin
`
`Eyes
`
`Ingestion
`
`
`
`
`
`
`
`
`PREVENTION
`Avoid inhalation of dust.
`
`
`
`Wear safety goggles.
`
`Do not eat, drink, or smoke during work.
`
`FIRST AID
`Fresh air, rest.
`Remove contaminated clothes. Rinse
`and then wash skin with water and
`soap.
`First rinse with plenty of water for
`several minutes (remove contact lenses
`if easily possible), then refer for medical
`attention.
`
`
`SPILLAGE DISPOSAL
`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.
`
`STORAGE
`Separated from incompatible materials. See Chemical Dangers.

`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.
