Natural Gas Safety Facts
As part of our ongoing customer education efforts, SEMCO ENERGY Gas Company offers these facts about Gas Company service and natural gas safety:
If you suspect a natural gas leak, leave the building or area immediately and call SEMCO ENERGY Gas Company from another location. Report natural gas leaks and related emergencies to the SEMCO ENERGY Gas Leak/Emergency line - 1-888-GAS-1-GAS (1-888-427-1427) - 24 hours a day, seven days a week.
- Natural gas is colorless and tasteless. To help you to recognize the presence of natural gas, SEMCO adds an odor similar to rotten eggs.
- Natural gas is lighter than air, rises quickly, and spreads out harmlessly in open areas. However, in an enclosed area, natural gas displaces air at ceiling level and fills the room from the ceiling down.
- Natural gas is not Liquefied Petroleum Gas (LPG). Liquefied petroleum gases, such as propane, are heavier than air, and unlike natural gas, will collect in low places.
- Natural gas is not toxic or poisonous. However, as natural gas fills an enclosed space, it displaces air and suffocation can occur.
- Natural gas cannot burn without oxygen. For natural gas to burn, it must be mixed with air and must have an ignition source, such as a pilot light or electric arc from a light switch, electric motor, doorbell, or telephone.
- Burning natural gas will not explode. In many cases it is better to let the natural gas burn than to extinguish the fire. If the fire is extinguished prior to stopping the flow of gas, the gas has the potential to build-up to an explosive level.

Transmission Integrity Management Plan
In accordance with the Federal Pipeline Safety Act of 2002, SEMCO ENERGY Gas Company has developed and implemented its Transmission Integrity Management Plan (IMP) for the Transmission Pipelines we currently operate in the State of Michigan. The integrity management regulations within the Pipeline Safety Act of 2002 were designed to address the monitoring and maintenance of high pressure natural gas transmission pipelines in areas where a leak or other failure could have a serious effect on populations or the environment. SEMCO’s IMP has been designed to continue to provide low cost natural gas to its customers while ensuring industry safety standards for operations.
SEMCO’s IMP also illustrates and describes how new programs, processes and procedures are integrated with established Company programs, processes and procedures to support, administer, and conduct the IMP. A copy of SEMCO’s Transmission Integrity Management Plan is available upon request.
HANDS OFF FOR SAFETY
Don't Tamper With Gas Company Equipment
SEMCO ENERGY Gas Company reminds its customers not to attempt to service any natural gas equipment between their main and the meter - no matter how simple the procedure may seem.
All equipment from the service main, up to and including your gas meter, is considered SEMCO property and should be serviced and maintained only by SEMCO Service Technicians or by a certified private contactor.Customer-owned gas lines and connections between your meter and your home should be serviced by a certified private contractor.
If you need to have the gas to your home temporarily turned off for any reason, please contact SEMCO ENERGY Gas Company at 1-800-624-2019 to schedule an appointment for a SEMCO Service Technician to turn off the gas. A Service Technician also will restore gas service to your home.
Turning the valve leading to your gas meter on or off, or operating any SEMCO ENERGY Gas Company equipment yourself, could result in a serious safety hazard. Adjusting any Gas Company equipment also can result in legal action by SEMCO ENERGY Gas Company.
Remember, natural gas is a safe, efficient, and economical fuel when connected and maintained by trained professionals, such as SEMCO ENERGY Gas Company Service Technicians or certified private contractors.
It's now easier than ever to contact MISS DIG either by phone or via the internet.
Michigan residents - whether Do-It-Yourselfers or professional excavators - can now just call 811 to have all utility lines located before beginning any digging or excavation project.
811 is the new toll-free nationwide "Call Before You Dig" number. Just dial 811 and your call will be routed to the local "Call Before You Dig" system. That's MISS DIG in Michigan. A call to 811 in Michigan will quickly begin the process of getting underground utility lines marked. MISS DIG System, Inc. will notify affected member utility companies to send crews to mark underground lines for free.
The existing MISS DIG number for Michigan - 1-800-482-7171 - still can be used to contact the state program. 811 is an additional, easy-to-remember access number for MISS DIG.
The 811 number can be called from any phone - land line, cell or cable phone. You can also go online at www.missdig.org to file a locating request.
Why call MISS Dig? Michigan law requires property owners to contact MISS DIG three (3) business days before beginning any project involving digging. This helps avoid possible injuries or damage to natural gas and oil lines, electric, telephone, TV cable and water or sewer facilities. Failure to call MISS DIG could leave you facing costly repair bills for damaged utility-owned lines.
What MISS DIG does not cover. Also be aware that, if you have any "customer-owned" pipes or lines in a project area, you are responsible for locating and marking them before your project begins.
Customer-owned pipes and lines are between the meter and your appliance. These include connections to yard lights, pool and spa heaters, garages, workshops, and similar areas.

Sewer Clogs and Utility Lines
That Clog Just Might Be a Utility Line
A blocked sewer line may be the result of another utility line (gas, electric, communications) having been accidently bored through the sewer line.
Attemping to clear this type of blockage can result in a serious accident involving loss of life, injuries, and significant property damage. Please follow the precautionary measures in this brochure to help prevent such accidents.
Identifying Gas Pipeline Markers
Natural gas pipelines are usually underground, which is why it is so important to contact Miss Dig before beginning any project involving digging.
In some situations, SEMCO ENERGY Gas Company is required to identify its pipeline locations.
The pipeline markers typically used by SEMCO ENERGY Gas Company (as shown) include a number for Miss Dig (1-800-482-7171). Miss Dig must be contacted three (3) business days before beginning any project involving digging so that all utility lines - including natural gas pipelines - can be marked. This is not only for your safety; you can be held liable for damage to unmarked lines.
SEMCO ENERGY Gas Company’s gas line markers also list a 24-hour emergency number - 1-888-GAS-1-GAS (1-888-427-1427). This number should be used ONLY to report emergencies.
If you have questions about this information, contact SEMCO ENERGY Gas Company at 1-800-624-2019. For a listing of pipelines in your area, please visit the Pipeline and Hazardous Materials Safety Administration’s National Pipeline Mapping System (NPMS) website at https://www.npms.phmsa.dot.gov/.
