Natural Gas Safety

Natural gas is odorless, but it is a common practice to add a distinctive chemical odorant called mercaptan. PCUD has done this so that you can more easily recognize the presence of natural gas, should you have a leak.

The chemical odor is frequently compared to the smell of rotten eggs. If you smell something like this, please call us immediately.

In the event of an emergency do not email PCUD. Call the PCUD’s 24-hour emergency line at (865) 426-2822 or (423) 562-2795.

How to determine if you have a Gas Leak
  • Is there an odor?
  • Do you hear air hissing or leaking?
  • Are you aware of any damage to the gas line?
  • Are you or another member of your family feeling dizzy, faint or ill?

If you answered yes to any of these questions, please contact PCUD by calling (865) 426-2822 or (423) 562-2795.

Carbon Monoxide Safety

Carbon Monoxide, a gas without color, odor or taste, is produced when gasoline and other fuels burn. When there is inadequate ventilation, Carbon Monoxide can become concentrated and have severe consequences, such as poisoning.

The most common sources of Carbon Monoxide are automobiles, furnaces and boilers that have not been properly maintained. Nobody is immune to Carbon Monoxide poisoning, but pregnant women, small children, older citizens, and people with heart or respiratory issues are more at risk.

How to tell if you might have Carbon Monoxide Poisoning

  • Do you have flu-like symptoms? (nausea, dizziness, drowsiness, vomiting, confusion)
  • Are you disoriented? Often, victims become aware they aren’t well, but are too disoriented to save themselves.
