HAZARDS IDENTIFICATION

************************EMERGENCY OVERVIEW********************
* Solid granules. May evolve irritating fumes on processing *
* or overheating. *
**************************************************************
Potential Health Effects:

EYE: Dust may cause irritation.

SKIN: Unlikely to cause skin irritation.

INGESTION: Low oral toxicity.

INHALATION: Unlikely to be hazardous but dust or vapors may cause
irritation.

CHRONIC (CANCER) INFORMATION: Potential decomposition products, ethyl
acrylate and styrene are suspect carcinogens

TERATOLOGY (BIRTH DEFECT) INFORMATION: No information but adverse effects unlikely.

REPRODUCTIVE INFORMATION: No information but adverse effects unlikely.

FIRST AID MEASURES

Inhalation: Remove patient from exposure. Obtain medical attention if ill effects occur.

Skin Contact: Wash skin with soap and water

Eye Contact: Remove particles by irrigating with eye wash solution or clean water, holding the eyelids apart. Obtain medical attention.

Ingestion: Do not induce vomiting. Wash out mouth with water. Obtain medical attention if ill effects occur.

Further Medical Treatment: Symptomatic treatment and supportive therapy as indicated.


FIRE FIGHTING MEASURES


Flammable Properties
Flash Point : NE

Combustible but not readily ignited. May form explosible dust clouds in air.

May decompose if heated above 200 deg. C. Combustion or thermal
decomposition will evolve toxic, irritant and flammable vapors.
Incompatible materials: None known.

Extinguishing Media: water spray, foam, dry powder or C02.
Fire Fighting Protective Equipment : A self-contained breathing
apparatus and full protective clothing should be worn in fire conditions.


ACCIDENTAL RELEASE MEASURES

Caution - spillages may be slippery. Sweep up and shovel into waste drums or plastic bags. Wash the spillage area with water.


HANDLING AND STORAGE


STORAGE
"ELVACITE" acrylic polymers are supplied in either drums or other
specialty packaging. Keep containers in a clean, cool and dry area away from heat sources. Natural ventilation is adequate.

Storage Temperature : ambient.

Avoid contact with eyes. Avoid prolonged skin contact. Avoid inhalation of high concentrations of dusts.

HANDLING
Process Hazards
Care should be taken to prevent burns from contact with hot material. All polymers degrade to some extent if over heated, an effect which increases with increasing temperature. It is therefore impossible to be precise about which substances may be evolved. However, it is only the minor components which vary substantially. The major components are given in the "STABILITY AND REACTIVITY" section.



EXPOSURE CONTROLS/PERSONAL PROTECTION

Normal handling: the use of eye protection is recommended. An approved dust mask should be worn if exposure to high levels of dust are likely.
