Manmade disasters are unpredictable and can spread across geographical boundaries. Some disasters in this class are entirely manmade while others may occur because of natural disasters, equipment failures, or workers are undertrained, ill-equipped, less qualified or overworked resulting in technical errors/ accidents.
Technological disasters include a broad range of incidents. Routes of exposure through water and food, airborne releases, fires and explosions, and hazardous materials or waste (e.g., chemical, biological, or radioactive) released into the environment from a fixed facility or during transport. Fires, explosions, building or bridge collapses, transportation crashes, dam or levee failures, nuclear reactor accidents, and breaks in water, gas, or sewer lines are other examples of technological disasters.
