************EMERGENCY OVERVIEW*****************************
* Clear or colored beads. 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: No evidence of adverse effects but adverse
effects unlikely.
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. Molten material can cause
severe burns. Do NOT try to peel molten polymer from the skin. Cool rapidly
with water. Obtain medical attention.
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
---------------------------------------------------------------------------
Combustible but not readily ignited. May form explosible dust clouds in air.
May decompose if heated above 280 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
"DIAKON" acrylic polymers are supplied in either bags or bulk containers.
Keep containers in a clean, cool and dry area away from heat sources.
Natural ventilation is adequate.
Storage Temperature: ambient.
HANDLING
Avoid contact with eyes. Avoid prolonged skin contact. Avoid inhalation of
high concentrations of dusts. Extra care should be taken to prevent burns
from contact with hot material.
Process Hazards
Burns are the most common injury during melt processing of thermoplastics.
Take utmost care. "DIAKON" grades can be processed safely in molding and
extrusion equipment at melt temperatures up to 280 deg. C. The more rapid
decomposition above these temperatures could cause gaseous pressure to be
built up, with a risk of spraying low-viscosity polymer from the nozzle or
die without any screw movement. All polymers degrade to some extent at their
processing temperature, 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. Care should be taken when despruing or degating
moldings as resultant edges can be sharp and may cause cuts to skin and
damage to eyes.
---------------------------------------------------------------------------
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.
Thermal processing: Wear eye/face protection. Wear thermal insulating
gloves when handling hot masses.
