What Is Liquefied Gas?<\/h2>\n\n\n\n

Liquefied gasses are gases that are in a liquid state at normal room temperature and stored in cylinders under pressure. Common examples of liquefied gases include nitrous oxide, anhydrous ammonia, chlorine, propane, and carbon dioxide.<\/p>\n\n\n\n

These gases are generally stored in a cylinder, with a bit of gas filling the space just above the liquid gas. Liquefied petroleum gas (LPG)<\/a> is generally available as propane, butane, or sometimes as a mixture of each. It is a colourless odourless liquid. Odorants are often added to such gases to detect any leak.<\/p>\n\n\n\n

Liquefied petroleum gas is often used as fuel in many industrial applications. LPG is highly flammable<\/a>, and because its denser than air, it tends to settle in low spots such as basements or drains, resulting in a suffocation hazard or increasing the risk of explosion.<\/p>\n\n\n\n

It\u2019s important to note that if LPG contains more than 0.1% Butadiene, it is also classified as a mutagen<\/a> and a carcinogen. It is commonly used as lighter fuel, as a refrigerant, as a propellant, and is a widely used alternative to gasoline. In many industries, LPG is a necessary substance required for the production of plastics or other chemicals.<\/p>\n\n\n\n

How Is LPG Made and Transported?<\/h2>\n\n\n\n

Liquefied petroleum gas is made when crude oil is refined or by processing natural gases. After further refinement, the LPG is renamed as either butane or propane, and in some cases, a mixture of the two.<\/p>\n\n\n\n

After it\u2019s refined, LPG is transported in larger vessels or gas cylinders. These cylinders are often loaded in trucks and transported in bulk quantities, which is different from natural gas, as that is transported through pipelines.<\/p>\n\n\n\n

In most cases, LPG exists as a vapor or a liquid when it is pressurized and stored in cylinders or tanks.<\/p>\n\n\n\n

The Many Safety Risks of Liquefied Petroleum Gas<\/h2>\n\n\n\n

The use of LPG in industrial applications often poses various risks. When working with LPG or other compressed gases, the risks are two-fold: those posed by the gas itself, and risks posed by the gas cylinders.<\/p>\n\n\n\n

Here are some of the most common safety risks and hazards when dealing with LPG:<\/p>\n\n\n\n
