This year’s deadly tornados have everyone thinking about emergency preparedness. Henry County Emergency management coordinator Deb Goetting has been thinking a lot about Mt. Pleasant’s outdoor warning sirens. Since beginning her position in April she has discovered as many residents already may know sometimes Mt. Pleasant’s six sirens work and sometimes they don’t. Replacement parts for the sirens are no longer available due to their age. So the question becomes should they be replaced. Tuesday the Mt. Pleasant City Council public safety committee met with a representative from Danko Safety systems. As expected, replacing the sirens would be costly. Depending on if they get battery back up and if the city does the bulk of the installation the cost could range from $9,900 to $13,000 a piece.
