Ridgefield Firefighters are asking that residents keep a few things in mind this 4th of July holiday.  Only sparkler effect fireworks are legal in Connecticut.  Purchasers should only buy from licensed dealers.  Children should be closely supervised around fireworks.  Only adults should be the ones to light them and they should be pointed away from people and buildings.  Only one firework should be lit at a time.  A bucket of water should be kept close by and used fireworks should be soaked in water before being thrown in the trash.  A dud firework should never be re-lit.
