Liquified butane and isobutane<\/strong><\/p>\n<p>Domestic cooking gas is a mixture of liquefied petroleum gases (LPGs), which are gases that have been compressed and cooled to a liquid state. The most common LPGs in domestic cooking gas are butane and isobutane. These gases are odorless and colorless, but they are often mixed with a small amount of a chemical called mercaptan, which gives them a distinctive smell.<\/p>\n<p>LPGs are a safe and efficient fuel for cooking. They are also relatively inexpensive and easy to store. However, it is important to use LPG safely. LPGs are flammable, so it is important to keep them away from open flames and heat sources. It is also important to ventilate <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> the area where you are using LPG, as the fumes can be harmful if inhaled.<\/p>\n<p>Here is a brief explanation of each option:<\/p>\n<ul>\n<li><strong>A.
