The operators will send a representative to your area to more clearly mark the depth and route of the line for you. The service is totally free and could save your life. You can also detect a leak by listening for a hissing or roaring sound or noticing a strange or unusual odor. It is also important to notify the company who operates the line. You can get their phone number from a pipeline warning sign.
Accidents happen, but they can generally be prevented.
One accident can also lead to another, just like little white lies. So, should you ever scrape, nick or dent a pipeline, do not cover the line back up to hide the mistake. Call the pipeline operator immediately. Even seemingly minor damage could result in a future leak or accident if not promptly and properly repaired. Out of Sight, Not Out of Mind Nobody wants an accident.
