Fortunately, our welder was okay. He was briefly exposed to a toxic fume that killed around 90,000 people over 100 years ago.
Mustard gas.
World War I
Mustard gas was used during World War I, primarily by the German forces. It was first used on July 12, 1917, causing more than 2,100 casualties. The Allies also began using mustard gas against German troops in June 1918.
Mustard gas was a significant chemical weapon during the war, causing more casualties than other chemical weapons such as chlorine and phosgene.
Although the mortality rate from mustard gas was *only* 2-3%, those who suffered chemical burns and respiratory problems dealt with long hospitalizations and, if they recovered, were thought to be at higher risk of developing cancers during later life.
Hidden Danger in Plain Sight
Why am I talking about mustard gas?
Brake cleaner is a popular tool for cleaning metal due to its degreasing properties and ability to remove oils, fats, and other contaminants from metal surfaces.
However, the danger existed because of a single ingredient: chloride.
When heated, chloride forms phosgene gas.
This gas has another name: mustard gas!

In Sum
Sometimes, article inspiration is as simple as seeing a headline in a trade publication. Other times, it's walking out to our shop floor.
I did that this morning when walking out to our machine shop, and I needed information from Frank, our incredibly talented Renaissance Man. As I spoke to him, my "Look! A Squirrel!" kicked in and I looked down to see an aerosol can that declared itself chlorine-free and was curious, so I asked Frank about it.
He told me that one of our previous safety coordinators learned about it while he was in the military and shared that information.
Frank told me he was lucky: he experienced those toxic fumes first-hand, hitting him like a hammer.
Luckily, his exposure was brief, but he still vividly remembers it.
Employers and welding personnel must adhere to safety protocols and adopt preventive measures to minimize risks.
By embracing safe alternatives and stringent safety practices, the overall workplace environment is significantly enhanced, promoting a culture of safety and well-being for all individuals involved in metal joining processes.
