Every home and business should have a Class B or ABC fire extinguisher handy. The flame retardant in a fire extinguisher is the most effective method for putting out small grease and home fires. Because the equipment to refill a fire extinguisher is very costly, having the device refilled by a professional is more cost effective. It’s also best to have a professional refill your fire extinguisher because you want to be certain it’s in working condition, as your life may depend on it.
