Blood Alcohol Concentration (BAC)
Blood Alcohol Concentration (BAC) refers to the amount of alcohol in an individuals bloodstream. A persons size, gender, weight, fat content and amount of food in the stomach will effect the absorption of alcohol in the bloodstream. The predominant factor in absorption is the metabolism of alcohol by the liver. When alcohol enters the bloodstream, 95% is metabolized by the liver and 5% is excreted in breath, sweat and urine. The liver takes about one hour per drink to clear the body of alcohol. Remember just one drink can impair your skills and judgment. It is risky to operate any machinery or engage in any activity that requires concentration and alertness after drinking any amount of alcohol. In the following chart, one drink is defined as 1 1/2 oz. of 80 proof liquor, 12 oz. of beer, or 4 oz. of wine.
