Are explosion venting panels the cheapest way of achieving ATEX compliance?

If you are lucky enough to have placed your plant or process near a wall or safe venting area then a venting panel is the cheapest way to protect your plant.  For 300 to 500 euro plus a small short explosion duct you can protect your plant and comply with ATEX.  If you have located the equipment in the middle of a busy work place and you cannot use explosion prevention measures, then you may have to consider, Flameless venting, Explosion Suppression or Containment never forget the needs for Explosion isolation!
