The tool allows people to test how effective policies and interventions would have been had they been implemented in the context of past droughts and it also allows them to explore different future scenarios to see the impacts of the policies, interventions and potential changes in climate.2.1 ‘NATURAL’ DISASTERS?Risk = Hazard X Exposure X VulnerabilityFigure 2.1: Commonly used elements and equation for disaster risk.Įxposure (X) means the quotient of dQ by dm where dQ is the absolute value of the total charge of the ions of one sign produced in air when all the electrons and positrons liberated or created by photons in air of mass dm are completely stopped in air thus X = dQ/dm, in units of C/kg. The exact relationship is defined different- ly in varying models.Risk = Hazard X Exposure X Vulnerabilityble fashion, using inadequate masonry techniques in earthquake-prone areas and settling unstable hillsides surrounding coastal cities with high precipitation levels. Yes File Risk AnalysisNo Risk = Exposure X Severity X Probability = E X S X P Controlling the RiskTo eliminate or minimize the risk, measures are proposed that should be implemented in an action-plan or job-plan. Primary Route(s) of Exposure X Inhalation _Skin _Ingestion Acute ToxicityEYE CONTACT: Direct contact with dust may cause irritation by mechanical abrasion. Risk = Exposure X Hazard Risk assessment should be flexible to deal with the complexity of real life situations. Environmental Exposure: May be exposed to chemically treated fluids 7.
