4. FIRST AID MEASURES
Eye contact: Rinse immediately with plenty of water, also under the eyelids, for atleast 15 minutes. Call a physician immediately.
Skin contact: Rinse immediately with plenty of water for at least 15 minutes. Ifskin irritation persists, call a physician. Cool skin rapidly with cold water after
contact with hot polymer.
Inhalation: Move to fresh air. Call a physician immediately.
Ingestion: Drink water as a precaution. Never give anything by mouth to an
unconscious person. Do not induce vomiting without medical advice. Call aphysician immediately.
Notes to physician: Treat symptomatically.

SPECIFIC HAZARDSFIRE FIGHTING INSTRUCTIONSOTHER INFORMATION

Auto ignition temperature: 380 ℃
Flammable limits in air – lower (%): Not
applicable.
Flammable limits in air – upper(%): Not
applicable.
Foam. Water. Carbon dioxide (CO2). Dry
chemical. Alcohol resistant foams are preferred if
available. General-purpose synthetic foams(including AFFF) or protein foams may function,
but much less effectively.
Above 300 ℃ , possible formation of Styrene,Toluene,Ketones and Alcohols (small quantities)
Formation of toxic products through combustion:
Carbon oxides, Hydrogen bromide
Keep people away, isolate fire area and denyunnecessary entry Cool surroundings with water tolocalize fire zone
Cool containers/tanks with spray water. Water mist
may be used to cool closed containers.
Fine dust dispersed in air may ignite. Risks ofignites followed by flame propagation of
secondary explosions shall be prevented by
avoiding accumulation of dust, e.g. on floors andledges.

Unusual Explosion Hazard and Fire: The material will burn if exposed to sufficient heat and anignition source. Avoid dispersion of dust in the air to reduce dust explosion hazard potential.
Extinguished Media: Water, Carbon dioxide, Dry chemical power, Foam. Special Extinguishing
Procedures: Firefighters must wear self-contained breathing apparatus and fully protective
equipment. Flammability: Autoignition temperature: 380°C

Flammability Limits in Air Flammable limits in air - lower (%): Not determined Flammable limits
in air - upper (%): Not determined Suitable extinguishing media: Foam. Water. Carbon dioxide(CO2). Dry chemical. Alcohol resistant foams are preferred if available. General-purpose synthetic
foams (including AFFF) or protein foams may function, but much less effectively. Extinguishingmedia which must not be used for safety reasons: No information available Hazardous
decomposition products: Burning produces obnoxious and toxic fumes Aldehydes Carbonmonoxide (CO) carbon dioxide (CO2) Special protective equipment for firefighters: As in any fire,
wear self-contained breathing apparatus pressure-demand, MSHA/NIOSH (approved orequivalent) and full protective gear. Under fire conditions: Cool containers / tanks with spraywater. Water mist may be used to cool closed containers. Other information: Fine dust dispersed inair may ignite. Risks of ignition followed by flame propagation or secondary explosions shall be
prevented by avoiding accumulation of dust, e.g. on floors and ledges.

6. ACCIDENTAL RELEASE MEASURES
Personal precautions: Use personal protective equipment. See Section 8.
Remove all sources of ignition. Avoid dust formation. Avoid contact with skin andeyes. Sweep up to prevent slipping hazard.
Environmental precautions: Do not flush into surface water or sanitary sewersystem. Do not allow material to contaminate ground water system.
Methods for cleaning up: Shovel into suitable container for disposal.
7. HANDLING AND STORAGE

Safe handling advice: Avoid contact with skin and eyes. Avoid dust formation.
Workers should be protected from the possibility of contact with molten material
during fabrication. Low hazard for usual industrial or commercial handling. Use
personal protective equipment.
Storage: Store in cool place. Keep at temperatures below 122F (50 °C). No
special restrictions on storage with other products
Precautions: No special precautions required
8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Engineering measures: Where reasonably practicable this should be achievedby the use of local exhaust ventilation and good general extraction. Provide
appropriate exhaust ventilation at places where dust is formed.
Control parameters: NonePERSONAL PROTECTIVE EQUIPMENT:
Eye protection: Safety glasses with side-shields. Goggles.
Skin and body protection:Impervious clothing.
Respiratory protection: Respirator must be worn if exposed to dust. Wear
respirator with dust filter. Consult an industrial hygiene professional prior torespirator selection and use. Use a postive-pressure air supplied respirator if there
is any potential for an uncontrolled release, exposure levels are not known, or any
other circumstances where airpurifying respirators may not provide adequate
protection.WARNING: Air purifying respirators do not protect workers inoxygen-deficient atmospheres.
Hand protection: Preventive skin protection.
Hygiene measures: Avoid contact with skin, eyes and clothing.
