INTOXICATION AU GAZ BUTANE PDF

NCBI Bookshelf. AEGLs represent threshold exposure limits for the general public and are applicable to emergency exposure periods ranging from 10 minutes min to 8 hours h. The three AEGLs are defined as follows:. However, the effects are not disabling and are transient and reversible upon cessation of exposure. Airborne concentrations below the AEGL-1 represent exposure concentrations that could produce mild and progressively increasing but transient and nondisabling odor, taste, and sensory irritation or certain asymptomatic, nonsensory effects. With increasing airborne concentrations above each AEGL, there is a progressive increase in the likelihood of occurrence and the severity of effects described for each corresponding AEGL.

Butane is a highly flammable, colourless, odourless gas. Butane is a hydrocarbon, found in household and industrial products and is potentially intoxicating if deliberately inhaled.

Butane is commonly misused by being inhaled directly through the mouth either from cigarette lighter refills, canisters or aerosol sprays. Butane is a central nervous system depressant which slows down the activity of the brain, affecting physical and mental responses.

When butane is inhaled the fumes are absorbed rapidly through the lungs into the bloodstream. The chemicals are soluble in body fat and pass rapidly to the brain and organs, so they take effect quickly. Although the initial high will last only a few minutes, the effects can continue for up to 40 minutes. Users may maintain the high by continuing to inhale the fumes.

It is difficult to calculate the dosage of butane being consumed by users so effects can vary between individuals. Dependence is usually psychological rather than physical. However physical withdrawal has been reported among some users. Tolerance to butane can develop quickly meaning that more of the substance is required to get the same effect.

Withdrawal symptoms can continue for a number of days when use ceases. Most deaths attributed to butane use are caused by SSDS. If the person gets excited, startled or participates in any sudden physical activity after inhaling butane, the heart can fail to pump blood. Butane users should receive the same support as individuals using stimulants.

Psychosocial supports should be provided by key workers or counsellors. Butane users generally function well in stimulant support groups. Download fact sheet. Download poster. English Gaeilge.

Domestic products such as spray deodorants, glue, lighter refills and spray air fresheners can be used as drugs. Volatile substance use may be defined as the deliberate inhalation of volatile compounds to produce psychoactive effects. These compounds have few characteristics in common, other than their intoxication effects and the behavioural effects they produce. Such volatile substances are often referred to as inhalants, a term which encompasses a diverse group of psychoactive chemicals that are defined by the route of administration, rather than their mechanism of action on the central nervous system or psychoactive effects.
