Document Summary
Hybrid disasters may fit into this category, ex. Technological disaster involving the environment are included in this category as well, ex. Typically, death tolls from technological hazards are relatively low. Vulnerability is greatest for those involved in industry or transportation systems, workers in resource industries in hinterlands at higher risk (ex. Extreme hazards: widespread and long term, cumulative effects (nuclear accidents) Rare catastrophes: airplane crashes, mine collapses, shipwrecks. Conditions that worsen slowly over time as exposure to a concentration increases, eventually reaches concentration critical to human health. Include exposure to toxic chemicals, acid precipitation, groundwater contamination, and ozone depletion. Large-scale structures: risk is defined as the probability of failure during the lifetime of the structure. Transportation: risk is the probability of death or injury per km travelled. Industry: risk is probability of death or injury per person per number of hours exposed.
