A possible HAZMAT situation in Brookfield has been mitigated.  Both of Brookfield’s fire companies were dispatched to the area of Cedar Hill on Friday for a reported pool house on fire. A large plume of smoke could be seen and first responders were concerned about the spread to the main residence.  As firefighters started to extinguish the flames, they discovered a large amount of chlorine tablets inside the pool house.  Since the water and heat from the fire could have dispersed that chlorine in a gaseous form; firefighters evacuated some nearby residences as a precaution.  After the gas had dispersed, the tablets were placed in a metal container for disposal.  The Fire Marshal is investigating the cause of the fire.
