LP Gas (Liquefied Petroleum Gas) is a combination of gases such as Propane, Butane, Butadiene, Butylene, Propylene and Isobutylene. The Propane and Butane are the most common.
In normal conditions LPG is a gas, but it transforms into a liquid if the pressure is higher than 2 bars.
LPG is gained from the extraction of petroleum and natural gas. It is also known as a by-product of crude oil refining. LPG gas is normally stored under pressure in steel or aluminum bottles, because in normal conditions it evaporates.
LPG have more than 1000 applications. It could be used for recreational purposes, in commercial business and obviously in households for heating, cooking or hot water. The history of using an LPG as a fuel started in 1800. Nowadays, not only are running LPG gas vehicles the cheaper alternative for those who want to save money, but also they pollute less the environment in comparison with petrol ones. Burning LPG are known to not produce carbon residues. As a result, engine oil in vehicles converted to LPG remains clear what contributes to reduction of greenhouse gas emissions.
High prices of petrol has led to growing popularity of cars that has been converted to LPG. The situation has brought many concerns about the safety of these cars. In the article you will find an answer on question: May LPG vehicles be parked in garages and especially in underground car parks?
Properly designed underground parking garages are suitable place for natural gas cars. Gas is much lighter than air. In case of leak, gas scatters upwards and may be easily removed by the special ventilation system that should be installed in the garage. On the other hand, propane is much heavier than air. In the event of leak it pools in low spots.
Modern LPG vehicles purchased after 2001, may be parked underground, in garages and car parks. It results from the fact that LPG tanks are equipped with the special safety mechanism responsible for minimizing the risk of leakage or explosion.
UN/ECE Regulation 67- 01 allows for parking LPG cars with a safety system on the first underground floor of multi-storey car parks.
