What is an Emergency?

Gas leaks, odor of gas, damaged lines, carbon monoxide symptoms and water main breaks are all considered emergencies.

If you smell gas, do not attempt to locate the leak. Instead, leave the house or building right away. Do not use any electrical switches, appliances, lights, telephones, or mobile devices, as an electrical charge could create a spark. When you are in a safe place, call M.U.D.'s emergency hotline at 402.554.7777 or 9-1-1.

If someone is showing symptoms of carbon monoxide poisoning, call 9-1-1 immediately. Symptoms are like the flu.

If you have a water-related emergency, call 402.554.7777. Our personnel are ready to assist you 24/7. When in doubt, call us immediately.

Why Does Natural Gas Smell Like Rotten Eggs?

rotten eggs

Natural gas is an efficient, safe, colorless and odorless gas. For easy detection, we add a harmless chemical called mercaptan to give gas a distinctive odor. Most people describe the smell as rotten eggs or hydrogen sulfide like odor.

It smells bad for a good reason - in case of a gas leak! If you smell natural gas, leave the house. Do not use a light switch, telephone or cell phone. Once you are safely out of the house call us at 402.554.7777 or 911. Our gas emergency line is open 24 hours a day, seven days a week. We immediately dispatch a service technician to your house to investigate the smell. When we arrive an adult must be present to meet us. Our average arrival time is under 35 minutes!

Besides utility companies need for mercaptan, there are other trades that use it. Industries use it for jet fuel, pharmaceuticals and livestock feed additives. It is used in many chemical plants. Mercaptan is less corrosive and less toxic than similar sulfur compounds found naturally in rotten eggs, onions, garlic, skunks, and, of course, bad breath. In other words, forms of mercaptan can be found in things that smell.
