Descriptionn-Butane is a hydrocarbon and one of two isomers of butane. Butanes are highly flammable, colorless, odorless, easily liquefied gases. They are components of gasoline and can also be used as refrigerants and propellants in aerosol sprays. Butane gas is sold bottled as a fuel for cooking and camping and is also found in cigarette lighters. Butane is a simple asphyxiant and commonly used substance of abuse that is responsible for a large number of "solvent related" deaths. (3, 4)

Toxicity Profile
Route of ExposureInhalation (3)
Mechanism of ToxicityButane is a simple asphyxiant and causes toxicity by displacing oxygen. It also affects the central nervous system by enhancing glycine receptors and inhibiting N-methyl-d-aspartate (NMDA) receptors. (4, 1)
MetabolismNot Available
Toxicity ValuesLC50: 658 g/m3 over 4 hours (Inhalation, Rat) (2)
Lethal DoseNot Available
Carcinogenicity (IARC Classification)n-Butane is found in gasoline, which is possibly carcinogenic to humans (Group 2B). (5)
Uses/SourcesButanes are components of gasoline and can also be used as refrigerants and propellants in aerosol sprays. Butane gas is sold bottled as a fuel for cooking and camping and is also found in cigarette lighters. Butane is a simple asphyxiant and commonly used substance of abuse that is responsible for a large number of "solvent related" deaths. (3, 4)
Minimum Risk LevelNot Available
Health EffectsButane targets the central nervous system and cardiovascular system. Inhalation of butane can cause frostbite which can result in death from asphyxiation and ventricular fibrillation. (3, 4)
SymptomsInhalation of butane can cause euphoria, hallucinations, confusion, blurred vision, slurred speech, nausea, vomiting, coughing, sneezing, increased salivation, drowsiness, narcosis, asphyxia, cardiac arrhythmia, and frostbite. (3, 4)
TreatmentTreatment for butane poisoning is supportive and symptomatic. Stimulants should not be administered. Recovery normally occurs quickly once exposure has ceased but support of the cardiovascular and respiratory systems may be needed. (4)
