⊙ When we use the butane gas in winter or a high mountain, a small amount remains. What would be the cause?
☞ The gas filled in the Fuel lines currently distributed in the market consists of butane gas (C4H10) as the main ingredient, propane (C3H8) and very small amount of hydrocarbon gas where 80% butane gas and 20% propane constitute the normal gas mix.
The reason why approximately 20% of propane gas is mixed in the Fuel lines is that the boiling point of butane gas becomes -0.5℃ in winter or low-temperature areas, due to the definite four seasons in Korea, making evaporation difficult with butane gas alone. Propane aids in evaporation.
Therefore, if you use the Fuel line in cold winter or low-temperature areas, the flame will weaken and the heating power will deteriorate, resulting in the small remainder of material. As a note, the boiling point of propane gas (C3H8) stands at -42.5℃, improving the evaporation capacity of Fuel lines and enabling its usage in cold winter.
⊙ Why do water beads form on the surface of a Fuel Line when using it in summer?
☞ The internal pressure of a Fuel Line rises proportional to the temperature.
In other words, butane gas is filled into our products in a liquid condition, but absorbs the heat in its surroundings to evaporate. Particularly, if you use a Fuel line at home in the summertime, a lot of water beads will form on the surface of the Fuel line; sometimes the can may frost in severe cases, which is a natural phenomenon occurring because of the stolen heat as mentioned above and is utterly not dangerous.
However, if the aforementioned phenomenon is too severe, the heating power may diminish. In that case, take the Fuel line out of the burner, wipe out the water, shake the can up and down about 5 times and put it back to boost the heating power
⊙ Nowadays, some juveniles inhale butane gas instead of taking hallucinogenic drugs. Does butane gas really cause hallucinating effects if one inhales it? And, does butane gas contain substances (ingredients) resulting in hallucinations?
☞ Butane - the main ingredient of LPG - is a hydrocarbon that consists of propane, propylene, n-butane, iso-butane, butylene, butadiene and pentane.
If a large amount of butane is inhaled one will experience slight narcosis, but the butane does not contain any toxicities. Legally prohibited narcotics such as toluene, ethyl acetate and methyl alcohol are not included in the fuel gas.
A human being must inhale air comprised of 20% oxygen to normally live, but if a large amount of butane gas is inhaled, the lack of oxygen will negatively impact the hemoglobin and other elements that supply nutrients to the brain, thereby restraining brain activity. People misunderstand the suffocation, dizziness and mental disorder stemming from the lack of oxygen as a narcosis.
⊙ I heard that a butane gas can will explode if kept in a car. Why is that?
☞ During the summertime, the temperature inside a car differs in various locations as direct rays of light shine in the car, but it could escalate to approximately 70 ~ 90℃ or more, raising the deformity and explosion pressure more than the level (13.0㎏/㎠ and 15.0㎏/㎠, respectively) that butane gas products can stand.
This may then result in explosion. In practice, we provide our customers only with products designed to endure the high pressure of 18.0 ~ 19.0㎏/㎠ - which is higher than the standard imposed by the High-pressure Gas Safety Control Law.
⊙ What precautionary measures should I take when using butane gas for a portable gas range?
☞ Precautionary measures when using the butane gas can for a portable gas range include closing the cover of the burner after putting in the butane gas, and avoiding direct heat on the cover.
In particular, if you put wide cooking equipment - such as a wide meat-grilling board or a bucket - over the gas range, the cooking equipment will cover the butane gas area and the heat generated on the cooking equipment will be transferred to the butane gas container (radiant heat), which frequently results in an explosion of the container.
Hence, please avoid using a wide meat-grilling board or a stone board. If you have to use such a board, place the board so that it will not veil the butane gas cover, avoid the overflow of the boiling food and make sure the oil for grilling meats does not directly fall on the butane gas container.
⊙ To prevent the small amount of remainder in winter, why don't you mix more than 20% of propane?
☞ That is a very risky idea.
Korea has a distinct cycle of 4 seasons, where the hot summer comes after the cold winter.
Our products' life cycle should range from 3 years to 5 years at the most. If we add more propane to eliminate the remainder in winter, the products are likely to possess the risk of explosion in summer, and the regulations related to high-pressure gas limit the internal gas pressure of Fuel lines to 5.0㎏/㎠ or below at 35℃.
In order to improve the remainder problem, Japanese manufacturers reduced the propane contents and attached a heat conductor board on the bottom of the burner - where you put in the Fuel line - transmitting the heat generated during the combustion to the surface of the Fuel line. This prevents the dew condensation effect (gas absorbs the heat around itself and evaporates and water beads form on the surface of the Fuel line) and facilitates evaporation.
With the Japanese burners, even the pure butane gas completely burns with the steady flame from the beginning to the end of combustion (currently, similar products are sold in the domestic market as well).
⊙ I heard that if you are caught when inhaling butane gas, you will be charged legally. Is that true?
☞ Yes, it is true.
If you are caught while inhaling butane gas, you will receive a monetary penalty of "3 years or less imprisonment or a 10 million or less fine" according to Article 35, Clause 6 of the Harmful Chemical Substance Control Law. In addition, the arrest is made upon principle in light of such an action for the sake of social isolation. Never inhale the butane gas
⊙ If the butane gas is leaking, what should I do? And, at what point does it explode?
☞ If you hear a leaking "shh" sound or smell gas while using a butane gas can for a portable gas range, quickly pull up the release lever of the burner to release the butane gas container and open the windows around you to circulate the air, which is very significant.
Owing to LPG's explosion range of 2.1 ~ 9.5% in the air, you must be careful because the small amount of LPG is likely to explode.
