VIDEO: The Plover Fire Department recently started using navigation compass devices in their masks. It not only helps crews combat structure fires but it also helps them save lives. "We've had two actual structure fires within the last week," said Plover Fire Dept. Captain Ethan Meddaugh. "One in the village of Plover and one in the village of Whiting." Time is everything when it comes to a fire. "Time is very valuable," says Meddaugh. "In a matter of seconds a fire can double in size." The compass devices make it easier for firefighters to find their way around when battling a blaze. "The mask can definitely help us in a structure fire to keep the hot air and smoke away from us and having to breathe in the fire," says Meddaugh. "But adding the new navigation device to our masks it has it readily available in our field of vision so we can see through the smoke."
