Which type of hazard includes chemical spills and nuclear accidents?

The correct identification of this hazard type as technological hazards is based on the nature of the events it encompasses. Technological hazards are typically associated with human-made systems and processes, including those involving machinery, transportation, and industrial activities. Chemical spills and nuclear accidents arise from industrial practices, improper handling of substances, or the failure of technology, which can lead to significant consequences for public health and safety.

In contrast, natural hazards stem from environmental forces such as earthquakes, floods, and storms. Biological hazards involve pandemics or biological threats, such as viruses or bacteria, that pose risks to health. Environmental hazards may broadly cover various pollution or ecological damage but generally do not specifically address the technological failures or accidents that characterize events like chemical spills and nuclear incidents. Therefore, the classification as technological hazards accurately reflects the root causes and implications of these events in the context of emergency management.
