INERIS action in the field of dangerous substances
Résumé
Since it was created in 1947. the Centre d'Etudes et Recherches de Charbonnages de France (CERCHAR) has devoted a considerable part of its activity to safety with regard to explosion risks in the Underground workings of coal mines. It has been concerned with the use of explosive products in these workings, the main aim being to reduce the risk of firedamp and coal dust ignition. For about twenty years, the work relating to explosive products has gradually included, on the one hand, their use in mines other than coal mines and in quarries and, on the other hand, the general safety (manufacture, transport, storage and use) of explosive products as a whole designed for civll use. In the same period, the work on gas and dust explosions has been extended to the majority of industries : chemical, petrochemical and the agricultural industry
