Section 4. First-Aid Measures

Fresh air, rest.

Remove contaminated clothes. Rinse and then wash skin with water and soap.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth. Do NOT induce vomiting.

Section 5. Fire-Fighting Measures

Use powder, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

Section 6. Accidental Release Measures

Evacuate danger area! Ventilation. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Personal protection: filter respirator for organic gases and vapours adapted to the airborne concentration of the substance.

Section 7. Handling and Storage

Separated from oxidants. Cool. Well closed.

No indication can be given about the rate at which a harmful concentration of this substance in the air is reached on evaporation at 20 °C.

The substance is irritating to the skin.

The substance defats the skin, which may cause dryness or cracking.

NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Do NOT use compressed air for filling, discharging, or handling.

PREVENT GENERATION OF MISTS!

Use ventilation.

Protective gloves.

Wear safety spectacles.

Do not eat, drink, or smoke during work.

Section 11. Toxicological Information

Petroleum distillates are central nervous system depressants and cause pulmonary damage. (A600)

No indication of carcinogenicity to humans (not listed by IARC).

Petroleum distillates are aspiration hazards and may cause pulmonary damage, central nervous system depression, and cardiac effects such as cardiac arrhythmias. They may also affect the blood, immune system, liver, and kidney. (A600, L1297)

The substance can be absorbed into the body by inhalation.

Oral (L400) ; inhalation (L400) ; dermal (L400)

Dry skin. Redness.

Petroleum distillate poisoning may cause nausea, vomiting, cough, pulmonary irritation progressing to pulmonary edema, bloody sputum, and bronchial pneumonia. At high amounts, central nervous system depression may also occur, with symptoms such as weakness, dizziness, slow and shallow respiration, unconsciousness, and convulsions. Petroleum distillates are also irritating to the skin. (A594)

Neurotoxin - Acute solvent syndrome

Treatment is mainly symptomatic and supportive. Gastric lavage, emesis, and the administration of activated charcoal should be avoided, as vomiting increases the risk of aspiration. (A600)
