Acetylene and Oxygen Cutting Torch - OSHA Says Oxyfuel Safety is Part of Welding Safety

Two Oxyfuel Safety Horror Stories - and one of them could have been a tragedy.

Story #1

A worker was returning from a lunch break and preparing to complete his task of cutting a truck u joint with an oxygen acetylene torch.

He turned on the Acetylene valve and then proceeded to open the valve on the oxygen tank. The oxygen regulator exploded which then saturated his shirt with oxygen. His shirt ignited and burn him severely on his torso. The cause of the accident was determined to be Regulator Burnout or RBO caused by the worker not bleeding down the pressures when he left for lunch.

Story #2

A worker was preparing for July 4th festivities by filling latex gloves with an oxygen and acetylene mixture. His plan was to be the hit of the neighborhood by lighting these latex glove bombs later that night. As he was carrying an armload of the explosive latex balloons, a static spark from the latex rubbing together made them all explode. A burned chest, some permanent hearing loss, and dislodged kidney stones that he wasn't even aware of were the price for stupidity that day. Had they ignited in the trunk of his Camaro, which is where he planned to put them, he would probably not have survived.

Oxyfuel equipment is dangerous.

Story #1 is understandable but entirely preventable by using known oxyfuel safety principles

Story #2 is natural selection at work. There is no excuse . And yet I sometimes see YouTube videos of people filling balloons with oxygen and acetylene and I think to myself "Holy Crap, they are all going to Die!"

Marijuana Tax Act of 1937 Opposed by the AMA (American Medical Association)

1936 - 1938: William Randolph Hearst's newspaper empire fuels a tabloid journalism propaganda campaign against marijuana. Articles with headlines such as Marihuana Makes Fiends of Boys in 30 Days; Hasheesh Goads Users to Blood-Lust create terror of the killer weed from Mexico. Through his relentless misinformation campaign, Hearst is credited with bringing the word marijuana into the English language. In addition to fueling racist attitudes toward Hispanics, Hearst papers run articles about marijuana-crazed negroes raping white women and playing voodoo-satanic jazz music. Driven insane by marijuana, these blacks -- according to accounts in Hearst-owned newspapers -- dared to step on white men's shadows, look white people directly in the eye for more than three seconds, and even laugh out loud at white people. For shame! 1936: DuPont obtains a patent license to manufacture synthetic plastic fibers from German industrial giant IG Farben Corporation. The patent license is obtained as part Germany's reparation payments to the United States after World War I. A few years later, IG Farben manufactures deadly Zyklon-B gas, used in Nazi death camps to murder millions of Jews (along with many homosexuals and drug users). DuPont owned and financed approximately 30% of Hitler's IG Corps, the military-industrial backbone of the fascist Third Reich. 1937: The year the federal government outlawed cannabis. -- DuPont patents petrochemical manufacturing processes for making plastics, as ...
