IND EX is the Intercontinental Association of Experts for Industrial Explosion Protection and since its establishment in July of 2009, the association grows steadily. IND EX` objective is to achieve a worldwide harmonized level of industrial Explosion Protection. Safety first is many corporations aim but the way they try to achieve this is too often not in line with enforced regulations and standards. A common platform is needed to create a common understanding of Explosion Protection.

And last but not least IND EX is the driver for new technologies and innovative safety practices and products. Its research programme includes scientific work. True to the motto „From Experts for Experts“, the association is also organizing Congresses and Symposiums to bring all the knowledge and expertise to the public.
