 And health officials are urging caution for those planning to set off fireworks on this 4th of July holiday. Ellen Walston, ECU Health Injury Prevention Coordinator, tells WITN fireworks should not be handled by young people. When children are playing with sparklers, they're running, they're excited, they may run into another child, again hit that child with the tip of the sparkler, so that just increases their risk for injury. According to Safe Kids Worldwide, more than 3,000 children under the age of 15 are sent to the emergency room each year
