Greater Danbury area Fire Departments are urging caution this holiday weekend when it comes to fireworks.  Fireworks injure over 10,000 people a year, with hand and finger injuries the most common, followed by head, face, and ear injuries.  People should only light one firework at a time, maintain a safe distance after lighting and never re-light or pick up fireworks that did not fully ignite.  A bucket of water or garden hose should be nearby in case of fire.
