least 15 minutes. Get medical attention immediately.

If swallowed : Clean mouth with water and drink afterwards plenty of water. DO NOT induce vomiting. If vomiting does occur, have victim lean forward to reduce risk of aspiration. Get medical attention immediately. Do not give milk or alcoholic beverages. Never give anything by mouth to an unconscious person.

4.2 Most important symptoms and effects, both acute and delayed

Symptoms : Signs of eye, throat, and respiratory tract irritation (cough and difficulty breathing), CNS depression (fatigue, dizziness, headache, collapse, coma and death) and possible cardiac sensitization may occur after exposure to high vapor concentrations.

Hazards : Moderate eye irritant. Causes moderate skin irritation. Aspiration may cause pulmonary edema and pneumonitis. Potential danger from aspiration must be weighed against possible oral toxicity when deciding to induce vomiting. May cause hearing loss.

4.3 Indication of immediate medical attention and special treatment needed

Treatment : Treat symptomatically. Treatment of overexposure should be directed at the control of symptoms and the clinical condition of the patient. Gastric lavage is indicated in those patients who require decontamination. Be sure that an endotracheal tube is in place prior to lavage; use cuffed tubes in patients over 7 years of age. Epinephrine and other sympathomimetic drugs may initiate cardiac arrhythmias (irregular beating) in persons exposed to this material.

which may cause release of styrene vapors forming flammable mixtures with air. Liquid normally inhibited but not vapors. Vapors may condense as solids, plugging pressure relief devices, causing overpressure/rupture of storage containers during runaway polymerization. Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Move containers from fire area if you can do it without risk. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. Always stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn. Eliminate all sources of ignition. Sustained fire attack on vessels may result in a Boiling Liquid Expanding Vapour Explosion (BLEVE). Fire residues and contaminated fire extinguishing water must be disposed of in accordance with local regulations.

5.3 Precautions for fire-fighters

Special protective equipment for fire-fighters

: Wear positive pressure self-contained breathing apparatus (SCBA). Structural firefighters protective clothing will only provide limited protection.

6. Accidental release measures

6.1 Personal precautions, protective equipment and emergency procedures

Personal precautions : Use personal protective equipment. Ensure adequate ventilation. Eliminate all sources of ignition. Evacuate personnel to safe areas.

11. Toxicological information 11.1 Information on toxicological effects

Acute toxicity

Acute oral toxicity Styrene : LD50 (Oral): ~ 5,000 mg/kg

Species: rat Remarks: This substance is of low acute toxicity when administered orally. Ingestion may cause discomfort and irritation of the gastrointestinal tract, effects on lungs and kidneys, and CNS depression (fatigue, dizziness and possibly loss of concentration, with collapse, coma and death in cases of severe overexposure) Aspiration into the lung may cause fatal chemical pneumonitis. May increase the sensitivity of the heart to endogenous catecholamines leading to potentially fatal cardiac sensitization.

Acute inhalation toxicity Styrene : LC50 (Inhl): 11.8 mg/l

Exposure time: 4 HOURS Species: rat Remarks: Vapors are toxic when inhaled. Vapors may cause irritation of the eyes, nose and throat as well as CNS depression (primarily fatigue, dizziness and loss of concentration, with collapse, coma and death in cases of severe over-exposure) May increase the sensitivity of the heart to endogenous catecholamines leading to potentially fatal cardiac sensitization.

Acute dermal toxicity Styrene : LD50 (Skin): > 2,000 mg/kg

13 / 42

Sensitization Styrene : Classification: Not sensitizing

Germ cell mutagenicity

Remarks Styrene : Styrene does possess some genotoxic potential in vitro

presumably reflecting conversion to styrene oxide. There is no convincing evidence from available animal and human data that styrene possesses significant mutagenic/clastogenic potential in vivo.

Carcinogenicity Remarks Styrene : Chronic inhalation resulted in hyperplasia and fibrosis and an

increased incidence of late onset lung tumors in mice, which are believe to have arisen through a non-genotoxic mechanism. Tumor incidence in rats was unaffected after chronic inhalation exposure. there is no convincing evidence that styrene possesses significant carcinogenic potential in humans.

Reproductive toxicity

Remarks Styrene : Results from reproductive toxicity studies in animals exposed

via drinking water or inhalation have shown no evidence of selective toxicity to the testis or ovary or adverse effects on fertility.

Teratogenicity Remarks Styrene : Results from animal studies demonstrate that styrene is not a

teratogen, nor is it fetotoxic at sub-maternally-toxic treatment levels. No selective effects on nervous system development have been reported. Some indication of developmental delay was observed in pups from dams exposed to high dose levels (500 ppm) however these findings were attributed to decreased pup body weight rather than a selective effect on the offspring.

Target Organ Systemic Toxicant - Repeated exposure

Styrene : Remarks: Results from repeat-dose toxicity studies demonstrate that the mouse is highly sensitive to styrene-induced toxicity, with hyperplasia and fibrosis in lung tissue and atrophy and degeneration of nasal olfactory epithelium after chronic exposure. Mild nasal changes were also observed in the rat. Mechanistic studies demonstrate greater formation of locally toxic products in mouse nose and lung, and provide a metabolic basis for these species differences in

susceptibility (negligible metabolism likely in human respiratory tract). There is clear evidence that styrene causes a specific adverse effect on hearing in laboratory animals after long-term exposure; additionally there is an indication for styrene-induced hearing losses in humans. Minor impairment of color discrimination has been reported in workers occupationally exposed to styrene, however the magnitude of the change is small suggesting it is of negligible toxicological or clinical significance.
