ECHA has long released the Exposure Scenario Format and also a modified version to incorporate Contributing scenarios based on revised understanding. Exposure Scenarios are the set of information on operational conditions and risk management measures to be communicated to the users. Generally exposure scenario consists of description of conditions suitable to ensure control of risk related to the uses of a substance during the entire life-cycle. Environment, Workers and consumers are included covering one or more exposure uses. Data required for Exposure Scenario include Substance Properties, amounts, emission factors, onsite measures, personal respiration protection, frequency and duration of exposure, frequency and duration of use etc, depending whether it is Environmental Exposure, Workers or Consumer Exposure Scenario.
However one of the challenges in using exposure format is the availability some practical examples of exposure scenarios. Last week ECHA released sample exposure scenarios constituting three substances. These scenarios are specific to Semi Conductor Industry. The lesson's learned therein like how to manage site specific conditions versus Site independent data and how air emission management could generate risk to water compartment are very much helpful to understanding the complexity of the process.The data available therein is very good source to validate SAP EH&S Data models for Exposure Scenarios and also checking suitability of WWI Templates.
