“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 [...]
“Ventilation is the profound secret of existence.” — Peter Sloterdijk Most people, when hearing about the legal limits of ethanol, will think of Blood Alcohol Concentration (BAC).

The question of whether whiskey needed an SDS came up. It [...]
“Perfection is not attainable, but if we chase perfection, we can catch excellence.” — Vince Lombardi I don’t believe that I have ever facilitated a perfect PHA. The question is, how would I recognize it if it was perfect? And would others agree? What exactly is a perfect PHA? A PHA Identifies Hazards The primary [...]
“Oxygen is the vital ingredient for the survival of every cell in our bodies. Too little—or too much—can spell disaster.” — Venki Ramakrishnan A reader recently complained about OSHA’s insistence on defining the safe limits of oxygen in terms of volume percent: 19.5% by volume to 23.5% by volume. “The fact that OSHA does not [...]
