Technological hazards often come with little or no warning. They originate from technological or industrial accidents, infrastructure failures, or certain human activities. Technological hazards can cause the loss of life or injury, property damage, social and economic disruption, or environmental degradation.

 Examples include:

• Airplane crash.
• Communications and/or computer database failure.
• Dam failure.
• Hazardous materials release.
• Power failure.
• Radiological release.
• Train derailment.
• Urban fire.
