KANSAS CITY, Mo. -- The Independence Fire Department is investigating after a fire early Tuesday morning. IFD said around 5:50 a.m. crews were sent to North Liberty Street for a fire in a shed detached from the house.

The department started an "aggressive fire attack" to prevent the fire from spreading to the house. The fire department said establishing a water supply was impossible as the hydrant was frozen. But crews were able to extinguish the fire with the water from their onboard water tanks.  “This morning, it was so cold out that the hydrant was frozen, and they were unable to establish that water supply. But fortunately, the apparatus has water tanks that hold approximately 500 gallons of water, and they were able to use that water on their apparatus to put the fire out this morning,” IFD Battalion Chief of Fire Prevention Eric Michel said. No injuries were reported, and the cause of the fire is under investigation. “It's like anything else in the fire service; you're going to encounter some adversity, and you have to be flexible enough to get around it and overcome it,” Michel explained.  In recent weeks, firefighters have faced several other challenges, from freezing temperatures, ice and lingering snow on the ground. “We spray water on fire, and the water's got to go somewhere on the ground, and it freezes, which creates fall hazards for us. Water leaks out of a hose line, even into the structure itself, creating a layer of ice on everything. Our bunker gear gets iced up and becomes more difficult to move around,” Michel said. Michel says hydrants aren’t supposed to freeze because the main line of a hydrant is buried underground. “If, for some reason, water would bypass the valve and get up in the barrel of the hydrant, it would be exposed to that cold, and that's why this one froze up,” Michel said. IFD notified the City of Independence’s Water Department about the hydrant issue.

The city inspects all of its hydrants annually, and the one on North Liberty St. passed inspection last year. A spokesperson for the City of Independence sent FOX4 the following statement: “The fire hydrant was not working - the stem of the hydrant wouldn't rotate when IFD tried to use it this morning. It appears to have been an operating system that seized up. We'll get out there to do a more thorough inspection soon - i.e., when it won't cause a puddle of water that quickly turns to ice and makes it a hazard for residents. I just want to clairify that it wasn't "frozen" with water in the cold. Our hydrants are dry-barrel hydrants; they don't store water in them. We recognize we live in the Midwest and these kinds of temperatures occur, so we have devices that are made to withstand these temperatures. “
