Hazardous Materials Reference Guide:

You can enter the UN number after starting the application using a big and easy to use keypad. Information can thus be retrieved quickly.

This product uses ERI-Cards based Information but is not endorsed, certified or otherwise approved in any way by CEFIC.

"The CEFIC Emergency Response Intervention Cards (ERICards or ERIC's) provide guidance on initial actions for fire crews when they first arrive at the scene of a chemical transport accident without having appropriate and reliable product specific emergency information at hand".

The ERICards are displayed as a table following the seven categories.

An internet connection is not needed to display the ERICards. Therefore, the app can be used with an ipod touch or in remote areas
without internet connection.


The information displayed is based on the CEFIC-"Emergency Response Intervention Cards" (ERI-Cards). They are available at the Cefic website free of charge. The price you pay for this application is for the user-interface, data-formatting and search function.

Cefic has developed ERICards in good faith and has made every effort to ensure the reliability and completeness of the information provided. They are designed as guidelines to be used by fire crews, in the case of an emergency response to a chemical transport accident. The information available on the ERICards should be applied on the basis of sound judgement, taking into consideration the particular circumstances of each accident and the specialised equipment available. Consequently, this information may not be sufficient or appropriate in all cases and the Cefic and 2denker will not be liable for the results of any misinterpretation or misuse of this information by fire crews or any other persons.
