TECHNOLOGICAL HAZARDS
Technological hazards are an increasing source of risk to people and
their environment. This is an effect of the globalization of production, an in-
crease of industrialization and a certain level of risk of accidents connected
with production, processes, transportation and waste management. Severe
accidents have happened which afflicted thousands of people. These have
found expression in the public demand to provide technical and organiza-
tional tools for the prevention and mitigation of disasters.
Structural collapse
Structural collapses are often caused by engineering failures. Bridge
failures may be caused in several ways, such as under-design (as in the Tay
Bridge disaster), by corrosion attack (such as in the Silver Bridge collapse),
or by aerodynamic flutter of the deck (as in Tacoma Narrows Bridge). Fail-
ure of dams was not infrequent during the Victorian era, such as the Dale
Dyke dam failure in Sheffield, England in the 1860s, causing the Great Shef-
field Flood. Other failures include balcony collapses or building collapses
such as that of the World Trade Center.
Power outage
A power outage is an interruption of normal sources of electrical pow-
er. Short-term power outages (up to a few hours) are common and have mi-
nor effect, since most businesses and health facilities are prepared to deal
