Quizplus · Accepted Answer

TWA (Time Weighted Average) is a type of exposure limit that defines the maximum amount of a substance that an employee can be exposed to over the course of an 8-hour workday. It is calculated by measuring the concentration of the substance in the air over a period of time and averaging it out. The TWA is designed to prevent long-term health effects from exposure to hazardous substances.
