Proportionate Advice Update

NCEC is proud to announce the introduction of new levels of proportionate advice in the 2015.2 release of its Chemdata software. We see this development as a significant step forward in helping the emergency services respond to chemical incidents safely but also efficiently.

Different chemical hazard databases are available to emergency responders around the world but the advice presented usually relates to bulk incidents or spills of around 200 litres. Chemdata is changing that! We have listened to feedback from our users that the majority of incidents attended involve much smaller quantities of around 1 litre or 25 litres so we have now included 4 levels of advice to cater for very small, small medium and large spills. The aim of this is to help emergency responders apply the appropriate level of PPE and decontamination for the size of incident they are dealing with thereby reducing costs and the time taken to deal with smaller scale incidents.

Initially this expanded advice is available for the top 30 substances that our users have told us that they search for but we will be extended that to more and more of our database of over 61,000 substances over the next few years.




Proportionate advice is available in all versions of Chemdata including our Pocket Chemdata apps for Android and iOS devices.

NCEC have applied proportionate advice in Chemdata by adding new levels of advice within the existing precautions advice and also adding scaled advice for personal protective equipment (PPE) and decontamination. Decontamination advice is based on the type of PPE used and the degree of contamination. Phrases relating specifically to ‘Immediate Life Saving (Snatch) Rescue’ have also been incorporated. NCEC’s definitions of spill sizes have been consulted on with a selection of current end users and agreed. The table below also shows how they compare to the North American Emergency Response Guide (ERG) definitions:
