This is the MCBut toxic chemical released by Butane, which is a gas in Butane flame. Butane is actually a flammable liquid and a compound gas having the capacity to decompose at high temperatures. The Butane gas is usually stored in bundles of twelve, called butties, although they are available in single bundles only. There are two types of bundles: light and heavy. Both types are equally useful and have their own special purposes.
However, Butane is no longer used as a fuel for an ignitor, although it was in use for many years as a flame ingredient for the production of smokeless fireplaces. Some Butane products also contain methylene chloride, which is considered as safe under certain conditions but is toxic when present in substantial concentration. The toxic effect is mainly due to the hydrochloric acid formed when the Butane is exposed to oxygen, as a result of which Butane (as well as other combustible substances) release toxic gases. These gases are highly soluble in water and thus react with other compounds present in the air.
The toxic effects are mainly due to the fact that Butane is made from hydrogen and carbon, and the presence of excess nitrogen makes it particularly vulnerable to the decomposition process. This problem can be easily solved by introducing extra nitrogen, though this will increase the cost of the final product and may have other adverse effects on the environment as well. In order to combat the toxic effects of Butane, manufacturers include an inert gas, Methylene Chloride, into their MCBut data pack. It is added in the blend at the rate of about 0.35 percent, and the amount can be increased depending on the manufacturer’s specifications.
However, the major threat to the user is the fact that Butane can release toxic vapors, which can aggravate respiratory diseases. Therefore, it is very important that Butane is stored in a suitable receptacle, such as a stainless steel or plastic container lined with lead foil to prevent the escape of volatile gases. Allergic reactions may also result in damage to clothes and skin. In case of accidental exposure, immediately wash the eyes and nose and cover the mouth and nose with a suitable ointment.
A useful MCBut data pack should contain the information regarding the amount of Butane contained in each packet and should be accompanied by a hazard symbol. At the end of the data pack, there should be a safety data sheet, which lists the contents of the packet and their intended purposes. There should be a statement to indicate the percentage of Butane present in the package. Some manufacturers include instructions for use and storage of the MCBut, in addition to the information in the safety data sheet. This enables users to minimize exposure to the substance.
The electronic health records currently available do not contain information on the health effects caused by the inhalation of Butane. However, the concentration of Butane in the air is a known carcinogen. The data pack should also include recommended concentration and other precautions for its use. Health organizations advise against the use of this substance.
