Over 200 million pounds of fireworks were set off annually. Fireworks are a class of low explosive pyrotechnic devices used for aesthetic and entertainment purposes. The most common use of a firework is as part of a fireworks display (also called a fireworks show or pyrotechnics), a display of the effects produced by firework devices. But on average, fireworks injured nearly 10 thousand people a year.
1 month after people: In rural Pennsylvania, thousands of pounds of explosive power sit idle in a fireworks factory. The fireworks and gunpowder lie dormant behind blast walls and their bunkers, and there will be no fireworks displayed this year, at least for now.
20 years after people: Vines and vegetation have covered the concrete and steel bunkers of the fireworks factory. For a decade, rainwater has been dripping into the deteriorating bunkers wetting the gunpowder and causing it to become even more volatile. The late summer dry heat had cause a wildfire, and causing it to burn out of control. The fire reaches the edges of the fireworks factory, and the flames lick through the cracks in the walls, causing the powder to ignites. Spreading like a domino effect, these fires spreads from bunker to bunker. The once prepared fireworks were destined for 100 different fireworks displays are now all go off at once.
