Hazardville originated as an industrial village centered around the manufacture of gunpowder using water power from the Scantic River. The first small black powder mill was established in 1835 by Allen Loomis in an area then known as Powder Hollow. This became the Hazard Powder Company.

Hazardville takes its name from Colonel Augustus George Hazard.[3]
