Document Summary
Vulnerability to technological hazards: typically, the death tolls from technological hazards are relatively low, vulnerability is greatest for those involved in industry or transportation systems, workers in resources industries in hinterlands are at higher risks (e. g. miners) Categories: widespread, long term (nuclear accidents, hazards leading to cumulative effects, rare events, airplane crashes, mine collapses, shipwrecks, common, automobile accidents, poisons. Industry (manufacturing, power production): risk is the probability of death or injury per person per number of hours exposed. It is difficult to detect because the gas is odourless, colourless and tasteless. In canada, uranium is mined in northern saskatchewan and northern ontario: mines produce wastes known as tailings that can be a radioactive hazard, production of electricity, uranium is used in nuclear reactors. Nuclear accidents: nuclear meltdown an informal term for an accident that results in damage from overheating, the hot liquid could melt through the bottom of the reactor and seep into the soil.
