Natech hazard and risk assessment

This document is the ninth and last in a series of hazard-specific risk assessment modules, compiled as part of the Words into Action Guidelines on National Disaster Risk Assessment by UNISDR. This section provides a general introduction to the assessment of the risk of natural hazard-triggered technological accidents. 

The impacts of natural hazard events on chemical installations, pipelines, offshore platforms and other infrastructure that process, store or transport dangerous substances can cause fires, explosions and toxic or radioactive releases. Although these “natech” accidents are a recurring feature in many natural disasters, they are often overlooked, despite the fact that they can have major social, environmental and economic impacts.
