The Practical tables contain IMPACT, STATE, PRESSURE and DRIVER tables (so called "ISPD tables") and also useful additional check-lists for screening ELD cases and for identifying cases of imminent threat of damage. The ISPD tables can be used for a complete assessment, namely during the whole investigation: they contain indicators to conduct the screening of ELD cases, identify the imminent threat of damage, identify the clues of environmental damage as well as the evidence of damage. Hence, the check-lists for screening ELD cases and for identifying cases of imminent threat of damage are additional to ISPD tables and can be used indipendently for their specific purposes.
