Process Safety in Distilleries: Electrical Classification

“To be beyond any existing classification has always pleased me.”  — Boyd Rice Every distiller understands that they are working with extremely explosive hazards. There is ethanol, a flammable liquid.  And there is milled grain, a source of combustible dust.

Combustible Dust: Probability of Ignition

“Before the first atomic bomb test, scientists took the time to calculate whether the blast would ignite the nitrogen in the Earth’s atmosphere and incinerate us all.

Carbon Dioxide: Silent but Deadly

“I had thought fermentation was controlled death.”  — Michelle Zauner I enjoy touring distilleries. I love seeing the process of making whiskey, but I’m usually taken aback when we get to the fermentation step. Occasionally, the fermenters are enclosed and vent to the roof. Most fermenters that I see, however, are open top vats. This [...]

Confined Spaces: Even in Craft Distilleries and Microbreweries

“I have a horror of being in confined spaces.”  — Hayley Mills At a craft distillery that is not too far from Bluefield’s offices, the owner spoke about his need to climb into the pot still to clean out the stillage, especially the spent grains. He saw me wince and said, “Yeah, I know. It’s [...]

One incident in Volume 3, though, was [...]

Hot Work: Explosion and Fire in Tequila, Mexico

“Tastes like heaven, burns like hell.” — Fireball slogan Tequila is a far cry from the cloying cinnamon-flavored spirit called Fireball. But they both have one thing in common: they burn like hell.
