ROUTE OF EXPOSURE
INGESTION:
Moderately Toxic. May cause gastrointestinal disturbances. Symptoms may include
irritation, nausea, vomiting and diarrhea. Exposure may cause symptoms similar
to those listed under "Inhalation" (see Inhalation section).
SKIN:
Moderately Irritating. Repeated or prolonged skin contact may cause reddening,
inflammation or blistering. May cause allergic reactions in some individuals.
Contact with heated material may cause thermal burns. Exposure may cause
symptoms similar to those listed under "Inhalation" (see Inhalation section).
EYE:
Moderately Irritating. Direct contact may cause temporary corneal lesions.
Contact with heated material may cause thermal burns.
INHALATION:
SLIGHTLY TOXIC. May cause respiratory tract irritation. May cause harmful
central nervous system effects. Effects may include drowsiness, impaired
balance, nausea, vomiting, loss of appetite and general weakness--
"Styrene Sickness". May cause blood changes and liver damage. The
disagreeable odor and irritation of this material make inhalation of acutely
toxic concentrations unlikely.
SPECIAL TOXIC EFFECTS:
Carcinogenic determinations: The International Agency for Research on
Cancer (IARC) has classified styrene in Group 2B (possibly carcinogenic
to humans). This classification is not based on any significant new evidence
that styrene may be carcinogenic, but rather on a revised definition for
group 2B and consideration of new data on styrene oxide.
A number of lifetime animal studies with styrene including those conducted
in the NCI bioassay program have not shown styrene to be carcinogenic.
Pre-existing medical conditions which may be aggravated by exposure include,
but are not limited to, chronic respiratory and skin disease and central
nervous system disorders.
******* EMERGENCY AND FIRST AID **********
INGESTION:
DO NOT INDUCE VOMITING BECAUSE OF DANGER OF ASPIRATING LIQUID INTO LUNGS
BURNING (IRRITATING) ESOPHAGUS AGAIN.
If spontaneous vomiting monitor for breathing difficulty. Keep affected
person warm and at rest. Get immediate medical attention.
SKIN CONTACT:
Wash area of contact thoroughly with soap and water. Remove contaminated
clothing immediately. Place contaminated clothing in closed container for
storage until laundered or discarded. If clothing is to be laundered, inform
person performing operation of contaminant's hazardous properties. Get medical
attention if irritation persists.
EYE CONTACT:
Flush immediately with large amounts of water for 20-30 minutes. Eye lids
should be held away from the eyeball to insure thorough rinsing. Get
medical attention if irritation persists.
INHALATION:
Remove affected person from source of exposure. If breathing is difficult,
give oxygen. Keep affected person warm and at rest. Get immediate medical
attention.
