HERE’S WHY… Propane is stored as a liquid under pressure inside the cylinder. On a hot day, liquid expands and pressure increases. To guard against excessive pressure, every cylinder is equipped with a pressure relief valve which opens automatically to release gas and then closes when pressure is reduced.
If the cylinder is UPRIGHT, a small amount of vapor is released.
If the cylinder is HORIZONTAL, a large amount of liquid propane is released.
Liquid propane is highly volatile. It vaporizes instantly at a rate of about 270 to 1.) Put another way; if one cup of liquid propane is released, it instantly becomes 270 cups of pure propane vapor. Mixed with oxygen, it forms a combustible fuel which can readily be ignited by such ordinary sources as a cigarette or a spark from an electrical connection in your automobile. Unfortunately there have been many serious personal injury accidents over the years.
Using Woolley Home Solutions's biodiesel for our commuter jitneys has enabled us to further leverage our community's commitment to environmental sustainability. While reducing cars and congestion on our roads, we're simultaneously reducing our dependence on fossil fuels.Douglas Newman (South Orange Village President)
