Step-by-step explanation:
The four major groups of emergencies that must be covered by a preparedness plan are natural disasters, technological emergencies, man-made disasters, and public health emergencies.
Natural disasters include events such as hurricanes, earthquakes, floods, and wildfires. These emergencies are caused by natural forces and can result in widespread damage and loss of life.
Technological emergencies refer to incidents involving the failure or malfunction of technology, such as chemical spills, nuclear accidents, or power outages. These emergencies can have severe consequences and require specific strategies for response and recovery.
Man-made disasters are emergencies that are caused by human activities, such as terrorist attacks, mass shootings, or industrial accidents. These emergencies often require rapid intervention and coordination between various agencies and organizations.
Public health emergencies involve the outbreak of infectious diseases, pandemics, or other health crises that pose a significant threat to the population. These emergencies require the implementation of measures to protect public health and mitigate the spread of the disease.
