Other names Butyl hydride  Quartane . These values are considered protective of the irregular breathing observed in guinea pigs exposed to butane at 21, ppm for up to 2 h.
In a continuous exposure test, subjects were exposed to butane at slowly increasing concentrations up to 50, ppm for an unknown duration but at least 10 min. A case report and literature review. By analogy to other CNS-depressing substances, the effects of butane are assumed to be solely concentration dependent. Odor detection was assessed by means of an odor scale ranging from 0 no detectable odor to 5 intense effect, may bite or irritate.
An ambulance arrived within 5 min. A fatal case of n-butane poisoning after inhaling anti-perspiration aerosol deodorant.
Butane | C4H10 – PubChem
Abstract LPG is a by-product of petroleum refining and is a wu gas with a mild odour. Therefore, safety considerations against the hazard of explosion must be taken into account. Neurotoxicity Several case reports of intentional butane exposure indicate that butane induces neurotoxicity.
Buane yearold male with a 3-year history of butane abuse was found collapsed and showing ventricular fibrillation. No AEGL-1 effects at 10, ppm for 10 min.
Cardiac status improved during hospitalization, but brain functions remained disturbed Bauman et al. Developmental and Reproductive Toxicity A pregnant year-old woman accidentally inhaled butane in during week 27 of her pregnancy. Total uncertainty factor of 3 for differences between species and individuals.
Death during deliberate propane inhalation. A species with a relatively high susceptibility is used.
Butane – Wikipedia
Mean butane concentrations in organs at the LC 50 were 7. Sudden death due to inhalation of these gases in abusers is the most encountered condition.
LPG is highly flammable and has a high fire and explosive hazard.
Genotoxicity Butane appears to be negative in the Ames test, with and without metabolic activation citation of an unpublished report in Moore Inhalation of butane during pregnancy weeks 27 and 30 of gestation at concentrations that produced unconsciousness in the mother caused clearly underdeveloped brains in intoxicatiin fetuses.
Legal Med ; 4: Case report The pregnancy of this healthy, non-consanguineous, year-old multigravida mother progressed nor- mally until the 27th week, when she suffered accidental intoxication from butane gas. Our patient had no evidence of fetal distress at birth, and congenital infection as the cause of the brain lesions was excluded.
The results of microbial mutation test for forty-three industrial chemicals; pp. Suicide by Inhalation of Suffocative Gas.
The only study with human volunteers Patty and Yant is rather old and focused on the warning properties of butane. A pregnant year-old woman accidentally inhaled butane in during week 27 of her pregnancy.
Suicide by Inhalation of Suffocative Gas
Suicide by propane-butane inhalation. Summary Butane was reported to cause cardiac sensitization in dogs, but the studies did not provide detailed information on exposure concentrations and duration or were performed on anesthetized dogs. Keep me logged in. Consequently, these values were selected as the reasonable lower and upper bounds of n to use when data are not available to derive an empirical value for n.
Of the 15 trials with individual dogs, three resulted in ventricular fibrillation. La madre inha16 accidentalmente gas butano a 10s seis meses de gestaci6n. Subjects first underwent the continuous exposure test, followed on the same day by the intermittent exposure test after a recovery period. An electrocardiogram showed an acute anterolateral infarction.
Butyl hydride  Quartane . She gradually became conscious, and 48 hours after admission she was discharged in a satisfactory condition. Tolerance to butane can develop quickly meaning that more of the substance is required to get the same effect.
If the person gets excited, startled or participates in any sudden physical activity after inhaling butane, the heart can fail to pump blood. Handbook of Chemistry and Physics.
Data on CNS effects are available for mice and guinea pigs. A newborn with hydranen- cephaly is reported whose mother suffered severe intoxication from butane gas during pregnancy. No further details were presented on actual exposure concentrations. The min AEGL-2 value is greater than the lower explosive limit butanne butane in air of 19, ppm.
Because human data are lacking, the AEGL-2 values are based on animal data. Because of these limitations, no clear conclusions can be drawn.
