Preliminary Screening

The preliminary screening step can be simplified by expanding general approaches ("response actions") into Technologies and Process Options. This is best done using either a table or a flow diagram (as shown below). Reviewing this table/flow diagram, it assists with the selection of approaches which are unlikely to be effective.

The table/flow diagram is developed from the long list of potential risk management options and is therefore site-specific. Consequently, a new table/flow diagram will have to be created for each new site.
