Final answer:
A person is considered intoxicated with a blood-alcohol percentage of 0.08% or higher. This is the typical legal threshold for intoxication and affects an individual's ability to perform tasks safely. The metabolism rate of alcohol in the human body influences the duration of intoxication.
Step-by-step explanation:
A member is considered intoxicated when they have a blood-alcohol percentage of 0.08% or higher. In terms of Health and safety regulations, this level has been established as the threshold for legal intoxication in most U.S. states and in other countries. Drinking alcohol affects the performance of tasks that require skill and judgment, and a blood alcohol concentration (BAC) at or above 0.08% is considered impaired to the point where operating vehicles or performing other dangerous activities is illegal.
Beyond legal considerations, higher BAC levels can lead to acute intoxication, loss of consciousness, and even death. The relative intoxication levels are proportionate to the rate of metabolism of alcohol in the body, which is about 15 mg/dL per hour. However, these effects can differ due to individual responses and the ability to metabolize alcohol, making it a personal experience for each drinker.
