Based on the hazard curves obtained, the uniform seismic hazard acceleration response spectrum (USHARS) is constructed for the location, according to the type of soil and the required hazard level (exposure time and exceedance probability).
Decision makers with different responsibilities require hazard information at various timescales (black bars on Fig. 4A) and levels of detail, with an emphasis on uncertainty.
First, land-use decisions require hazard-zonation maps that are scientifically defensible, accurate, and understandable, given the potential for political, social, or legal push-back from various constituents.
If, however, PCPs were classified and labelled in accordance with the CLP, many of them would require hazard pictograms on the label [26].
If, however, PCPs were classified and labelled in accordance with the criteria of the European regulation on classification, labelling and packaging of substances and mixtures (CLP-regulation [8]), many of them would require hazard pictograms on the label [9].
Information management: Requiring hazard information to be included on land information memoranda issued by the local council, and requiring applicants to provide hazard information where uncertainty exists, are useful ways to encourage hazard information to be used in the planning process, prior to its formal inclusion in a land use plan.
For example, the United States Geological Survey operate dual volcano alert level systems to accommodate both the aviation industry, who require hazard information as rapidly as possible, and those responsible for hazard response on the ground who may prefer a lead time to inform and educate decision makers (Fearnley et al., 2012).
There are significant hazards from almost all Canadian volcanoes that require hazard maps and emergency plans.
And in July, when a rule requiring hazard-control plans at food manufacturing facilities came due, again -- nothing.
Such risk assessment requires hazard identification and dose response data.
It was found that stricter concentration standards were required for hazards that are more strongly bound to soil and/or are more toxic/infectious.
