Review the site's classification of headings
I use chemicals. How do I know if my site qualifies for ICPE classification?

For each ICPE heading :

• subtotals, i.e. by hazard class, substance or chemical family according to the heading;

• deduct the regime applicable by ICPE heading ;

• compare the resulting diet with the previous one;

• if there is no change in regime and you are under authorization, compare plant capacities (% increase or decrease).

INERIS and the French Ministry of the Environment have published a technical guide to help operators determine SEVESO status: "Application de la classification des substances et mélanges dangereux à la nomenclature des installations classées pour la protection de l'environnement". This guide is available on the INERIS CLP helpdesk website (home > focus > CLP and ICPE/Seveso 3)....
