 Dr. Samuel Gerber estimated that the initial death toll stood at 200; however, Gerber was quoted in newspaper wire stories stating the magnitude of the fire and the intense temperatures had the power to vaporize human flesh and bone, making an exact count impossible until weeks after the disaster. The final death toll was lower than the coroner’s initial estimates.

The toll could have been significantly higher had the event occurred after local schools had let out and working parents returned to their homes for the evening. In all over 600 people were left homeless, and seventy homes, two factories, numerous cars and miles of underground infrastructure destroyed.

Following the explosions and fires, East Ohio Gas worked to assure the public that the destroyed plant only held 24 hours worth of gas for the city. Many families living in the area not only lost their homes, but stocks, bonds and cash, which many kept at home. Estimates for destroyed personal and industrial property ranged between $7,000,000 and $15,000,000.

Following the disaster, utility companies and communities began to rethink their natural gas storage systems, and below ground storage of natural gas grew in popularity.

The disaster plays a major role in Don Robertson's 1965 novel "The Greatest Thing Since Sliced Bread."
