Webb31 maj 2024 · Risk evaluation involves the determination of whether a risk reduction is required for a particular hazard. Manufacturers should weigh the combination of the probability that a hazard occurs with the severity level of the hazard. A risk evaluation matrix, such as the following example, is often used to to visualize risk acceptability.
