An eyewitness account described the impact as "a burning sensation in the head, red-hot needles in the lungs, the throat seized as by a strangler. He served as a private in Company B, 7th Infantry before rising to a sergeant in Company H, nd Infantry, 36th Division, a consolidated unit of infantries from Oklahoma and Texas.
After training at Camp Bowie, Cox was deployed to Europe where he was one of 70, Americans exposed to gas during the war. Smithsonian has written about Haldane before , because he was the man who devised the idea of using canaries and other small animals in coal mines to detect odorless, deadly gases.
He had also done previous work on how to protect miners from gas using respirators, according to Jerry Chester for the BBC. His job was to ID the kind of gas that was being used. Haldane and his team were able to identify the gas used at Ypres as chlorine by examining discolored metal buttons on soldiers' uniforms. After he returned to his home in Oxford, England, he started experimenting to find out what would keep the gas out. On himself. The latter were formed millions of years ago after dead plants and animals mingled with silt, sand or calcium bicarbonate and over time became buried deep under Lake Erie.
Multiple layers of sediment added pressure and heat to this mixture, eventually transforming the carbon and hydrogen it contained into natural gas. More than three trillion cubic feet of it lie beneath the lake. And just before midnight on July 24, , the sandhogs struck an explosive pocket.
By the time Morgan was called in and descended the tunnel, bodies from the two previous rescue parties lay strewn across the tube. But eight men were still alive, and Morgan hauled them all to safety. Morgan was indignant. Some five years later, in the early s, the inventor witnessed a horrific accident between an automobile and a horse-drawn cart at an intersection. Once again, his ingenuity kicked in.
Before Morgan, traffic signals only had two positions: stop and go. He purchased acres later that year in Wakeman, Ohio, and transformed it into an African American country club complete with a party room and dance hall. The inventor founded Siebe, Gorman and Co. In , Lewis P. Haslett patented an "Inhaler or Lung Protector," the first U.
Haslett's device filtered dust from the air. In , Scottish chemist John Stenhouse invented a simple mask that used charcoal to filter noxious gases. The device was made up of a nose clip, and a mouthpiece attached to an air tank that the rescue worker carried on his back.
In , British physicist John Tyndall invented a fireman's respirator that filtered air against smoke and gas. In , British inventor, Samuel Barton patented a device that "permitted respiration in places where the atmosphere is charged with noxious gases, or vapors, smoke, or other impurities" according to U. American, Garrett Morgan patented the Morgan safety hood and smoke protector in Two years later, Garrett Morgan made national news when his gas mask was used to rescue 32 men trapped during an explosion in an underground tunnel feet beneath Lake Erie.
The publicity sold the safety hood to firehouses across the United States.
