During the high season between August and Christmas, people in Mexico state buy more than 100 tons of fireworks, according to officials there.
Adriano Serrano Rosas, the owner of the house that was leveled, said he lost three children and two grandchildren, all of them between 4 and 18 years old.
At least 14, including five children, have died following an explosion in a fireworks warehouse in Mexico, according to reports. Fireworks vendors and manufacturers said it will duplicate the previous market in size, with space for 300 vendors.
The explosion, which was heard 10 kilometers away, took nine members of the Serrano family and destroyed their house.
It is thought that at least 30 people have been injured.

The fireworks explosion on Monday is one of a few that have happened in Mexico in recent years. The market had seen two explosions in 2005 and 2006.
