Which of the following is NOT a primary objective of a human effect episode investigation?

Improving work practices, while certainly important in the context of safety and environmental health, is not typically classified as a primary objective of a human effect episode investigation. The main focus of such investigations is to understand and evaluate the immediate effects and circumstances of exposure incidents.

The primary objectives emphasize understanding the nature and extent of exposure, determining if any regulations or safety guidelines were violated, and identifying the circumstances that led to the exposure. These objectives are critical for ensuring proper responses to incidents, protecting public health, and preventing future occurrences.

While enhancing work practices can be a byproduct of insights gained from the investigation, it falls more under the realm of ongoing occupational health and safety improvements rather than being a direct objective of an episode investigation itself. Thus, it is not included among the core goals of assessing the impacts of a specific exposure event.
