A report by the U.S. Consumer Product Safety Commission and a study in Pediatrics estimate 6,400 fireworks-related injuries -- more than two-thirds of all fireworks-related injuries in 2006 -- occurred between June 16 and July 16, a statement by the Centers for Disease Control and Prevention said.

During that same time period:

-- One out of every three people injured were children under 15 years of age.

-- About three times as many males were injured as females.

-- Young people under age 20 sustained nearly half of all injuries from fireworks.

People actively participating in fireworks-related activities are more frequently and severely injured than bystanders.

Injuries most often affected the hands -- 2,300 injuries, 1,500 injuries affected the eyes and 1,400 injuries affected the head, face and ear.

-- More than half of the injuries were burns.

-- Fireworks can be associated with blindness, third-degree burns and permanent scarring.
