Document Summary
Has wide and varied interpretation; can vary from a single toxic chemical accident to an entire industry such as nuclear energy. Other examples include exposure to pollutants or hazardous waste. Hybrid disasters may fit in this category. Example: an earthquake that causes an oil or chemical spill from a pipeline. Technological disasters involving the environment are also included in this category. Example; sinking of the titanic, explosions of the challenger and columbia space shuttles. Vulnerability is greatest for those involved in industry or transportation systems. Workers in resource industries in hinterlands are at higher risk ( e. g. miners) There are 3 types of technological hazards: extreme hazards. Widespread and long-term (such as nuclear accidents) They are conditions which worsen slowly over time as exposure to concentration increases. Situations related to this include exposure to toxic chemicals, acid precipitation, groundwater contamination, and ozone depletion. Eventually, the concentration reaches a threshold critical to human health.
