An explosion from a chemical reaction in a Pacifica neighborhood Wednesday injured one person and resulted in a five-hour road closure, according to a news release from Pacifica police.

Around 6:12 p.m. Wednesday, Pacifica police and North County Fire Authority workers arrived to the 1000 block of Everglades Drive after receiving a report of an explosion.
