Across Washington on the Fourth of July, the pop of fireworks was often followed by the whine of sirens.

The D.C. fire department responded to 17 outdoor fires after dark on Friday. Spokesman Tim Wilson said that fire investigators did not go to the scene of all of those incidents, so the fire department cannot confirm that all were caused by fireworks, but Fourth of July festivities were likely to blame for most of the blazes.

Wilson said that no one was injured in any of the Friday night fires in Washington.

Many types of fireworks are legal for home use in the District and some surrounding counties. Other jurisdictions strive for a quieter night: In Montgomery and Prince George’s counties in Maryland and the cities of Alexandria and Falls Church in Virginia, all fireworks are illegal.
