Capt. Gregg Karl says the first step to fireworks safety is to make sure you’re using fireworks that are legal in Arlington County. Any fireworks purchased from an authorized fireworks stand in the county should comply with county regulations, Karl said. Those regulations specify that the fireworks emit a flame or spark less than 12 feet in the air.
Any fireworks that are “projectiles, explode, emit flames or sparks to a distance greater than twelve (12) feet are prohibited by Arlington County,” according to the county’s fireworks safety web page. The fire department also has a 42 page long list of fireworks approved for use in Arlington.
