5/18/1927 The Bath School disaster killed forty-five and injured fifty-eight, most children in the second to sixth grades, attending Bath Consolidated School in Bath Township, Michigan. In the morning a school board member, Andrew Kehoe, upset by a property tax levied to fund the construction of the school building. He killed his wife, set his farm buildings on fire, and detonated dynamite and hundreds of pounds of pyrotol he planted inside the school. As rescuers arrived at the school, Kehoe drove up and detonated a bomb inside his shrapnel-filled vehicle that killed himself, the school superintendent, and several others. An additional 500 pounds of unexploded dynamite and pyrotol was discovered planted throughout the basement of the school’s south wing… “Pyrotol was an explosive available for a time after World War I. It was reprocessed from military surplus. Usually, used in combination with dynamite, it created an incendiary blast. Since it was very inexpensive, it was often used by farmers to remove tree stumps and clear ditches.”
5/18/1918 the Aetna chemical explosion in Oakdale, Pennsylvania claimed 193 lives both inside and outside the facility. “At noon an explosion in a room used to mix chemicals inside the plant triggered a chain of blasts and fires that claimed 193 lives both inside and outside the facility, according to NFPA data. The catastrophe remains the deadliest fire or explosion in a manufacturing plant in U.S. history, according to NFPA. … Only about half of the victims could be identified, … the bodies of the other people lost in the blast had been incinerated among the wreckage of the plant. The company suffered an estimated $2 million in losses, and an additional $200,000 of damage was inflicted on nearby properties. An investigation revealed that the blast occurred because Aetna, which manufactured TNT for the Allied powers in World War I, ignored an order from the federal government to stop using a chemical that was linked to dangerous reactions, … Even so, the company was never held accountable for its actions. The Oakdale plant closed six months after the explosion.”
