Section 11. Toxicological Information

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

2,2,3-Trimethylbutane is found in gasoline, which is possibly carcinogenic to humans (Group 2B). (L135)

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)

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

Heptane affects the central nervous system and may cause lightheadedness, giddiness, stupor, vertigo, incoordination, loss of appetite, nausea, and unconsciousness. Direct skin contact with heptane may cause pain, burning, and itching. (T29)

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)
