RSA Online and Blood Alcohol Concentration (BAC)

Learning to estimate Blood Alcohol Concentration (BAC) is fundamental to the responsible service of alcohol.

Blood Alcohol Concentration (BAC) is simply how much alcohol is in the body. BAC is measured in grams of alcohol per 100 millilitres of blood (g%). For example, a BAC of 0.05% means that there is 0.05 grams of alcohol in every 100 millilitres of blood.

Blood Alcohol Concentration varies

The more a person drinks, the higher their BAC, however, two people who drink the same amount of alcohol might register quite different BACs. Reasons for this include a person’s body size, gender (men are generally able to tolerate alcohol more efficiently due to body fat ratios) and even experience. Seasoned drinkers have a greater tolerance to alcohol so their blood alcohol concentration will often be lower than inexperienced drinkers.

So how do I keep my BAC below 0.05%?

According to the Australian Drug Foundation average sized men can keep their BAC below 0.05% if they don’t consume more than two (2) standard drinks in the first hour and no more than one in every hour after that.

For women who are average sized, to stay under the limit they must not have more than one standard drink every hour.

Remember that alcohol can affect people differently, so use the above formula as a guide. The South Australian Drug and Alcohol Services has a cool app called “Drink Meter”. Check it out to help you to estimate your Blood Alcohol Concentration through a simulated drinking session.
