AIR NATURAL GAS PROPANE C C H H C H H H H H H C H H H H UNDERSTANDING THE SCIENCE —  THE MORE YOU KNOW Part of Columbia Gas’s presentation featured a live demonstration of what can happen when gas is released into the atmosphere. Possessing a clear and more complete perspective of the types of reactions associated with these fuels is paramount in deciding how to respond to a potential hazard. Those outside the gas and energy industries may not realize the property difference between propane and natural gas. Propane, a larger molecule, is heavier than air and falls when released, while natural gas is lighter than air and rises. This is important knowledge to have if one of these gases has an unplanned release at a job site. The live demonstration brought the properties of these fuels to life for everyone at the training, creating a vivid and memorable connection between partners through safety. T H R E E DIG WITH C.A.R.E. Excavation damage to a gas facility (e.g., gas line, pipeline, etc.) is the biggest risk factor. Don’t add to the statistics by violating the Underground Utility Prevention Act — use lawful best practice by digging with C.A.R.E.: Call 811 before you dig. Allow the required time for marking. Respect and protect the marks. Excavate carefully. If a gas facility is damaged at a job site, contact the gas emergency hotline found on the utility’s website. Learn more at Call811.com.
