Frequently Asked Questions

Gas Leaks

What do I do if I detect a gas leak?
If you suspect a natural gas leak, leave the area immediately, then call us at 1-888-427-1427. Do not use any electrical devices, such as light switches, telephones, computers, or appliances, such as garage door openers. They could generate a spark and ignite the gas. Do not try to locate the source of the gas leak or try to shut off any gas valves or appliances. Once you have exited the building, do not re-enter the building or return to the area until a SEMCO ENERGY Gas Company service technician says it's safe to do so.

If you are digging and think you may have damaged a natural gas pipeline, leave the area immediately. If you are using motorized equipment and can turn off the motor safely, do so to prevent the ignition of any leaking gas. Then, abandon the equipment and leave the area. Never restart equipment until the surrounding environment has been checked and declared safe. More Info

Energy Conservation

What can I do to reduce energy use in my home?
There are four easy ways to reduce your home’s energy use. First, lower your thermostat. Each degree you lower the temperature cuts your utility bill by one or two percent. Second, close vents to unoccupied rooms. Third, seal windows with plastic to stop drafts and avoid unneeded heat loss. Lastly, change filters on your furnace on regularly. More Info

Reading Your Gas Meter

The dials on the gas meter register the amount of gas used in units of 100 cubic feet. Reading a meter is similar to reading a clock. Here's what to do:
  1. Face the meter and read the dials from left to right. Read the numbers as indicated by the hands on the dials.
  2. If a hand is between two numbers, read the smaller number; except when the hand is between 0 and 9 as in A below, in which case you record the number 9.
  3. In the illustration below, dial A reads 9; dial B reads 0; dial C reads 8; and dial D reads 5. Therefore, the correct reading for this meter is 9085. Some meters do not have dials as illustrated. Instead, the meter will look like a mileage indicator on an automobile. In this case, a meter reading would appear as indicated.

Consumer Product Safety Commission
Carbon Monoxide Questions and Answers
CPSC Document #466

  1. What should you do when the Carbon Monoxide (CO) detector/alarm sounds?

Never ignore an alarming CO detector/alarm. If the detector/alarm sounds, operate the reset button. Call your emergency services (fire department or 911). Immediately move to fresh air -- outdoors or by an open door/window.

  1. What is CO and how is it produced in the home?

Carbon monoxide (CO) is a colorless, odorless, and poisonous gas. It is produced by the incomplete burning of solid, liquid, and gaseous fuels. Appliances fueled with natural gas, liquefied petroleum (LP gas), oil, kerosene, coal, or wood may produce CO. Burning charcoal produces CO. Running cars produce CO.

  1. What are the symptoms of CO poisoning?

The initial symptoms of CO poisoning are similar to the flu (but without the fever). They include:

    • Headache
    • Fatigue
    • Shortness of breath
    • Nausea
    • Dizziness

Many people with CO poisoning mistake their symptoms for the flu or are misdiagnosed by physicians, which sometimes results in tragic deaths.
